Binational Divorce in Brazil: US-Brazil Jurisdiction, Asset Division & Child Issues

Why Is Binational Divorce Between the US and Brazil So Complex?

Divorce is difficult in any circumstance. When a marriage spans two countries — two legal systems, two property regimes, two sets of custody rules, two languages, and often two very different expectations about spousal rights — the complexity multiplies in ways most couples do not anticipate until they are in the middle of it.

I write this guide from a position of unusual specificity. As an American-born attorney admitted to the Brazilian Bar (OAB/SP 351.356) with a USC LL.M. in international family law, I have represented both American and Brazilian spouses in binational divorces — handling the Brazilian-side proceedings under the OAB and coordinating closely with US-licensed counsel on the US side. I have filed divorce proceedings in Brazilian courts, sought homologation of US judgments at the STJ, coordinated QDRO filings with US counsel, and navigated Hague Convention custody disputes. This is not a theoretical overview — it is a practitioner’s guide to the real issues that arise when US-Brazil marriages end.

The core challenge is jurisdictional fragmentation. Brazilian law governs Brazilian assets. US state law governs US assets. Custody depends on the child’s habitual residence. Spousal support enforceability depends on where the payor has assets. And the two legal systems do not automatically recognize each other’s judgments. Every binational divorce requires parallel legal strategies in both jurisdictions — or, at minimum, a Brazilian strategy that accounts for US implications.

“I tell every binational couple the same thing at the first consultation: your divorce will be resolved in two legal systems, whether you plan for it or not. The only question is whether you coordinate those systems strategically or let them collide chaotically. The cost difference between those two approaches is often six figures.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

Which Country Has Jurisdiction Over a Binational Divorce?

Jurisdiction is the threshold question in every binational divorce. Under Brazilian law, jurisdiction is governed by Articles 21–23 of the Código de Processo Civil (CPC), as supplemented by Article 7 of the Lei de Introdução às Normas do Direito Brasileiro (LINDB).

When Brazilian Courts Have Jurisdiction

Brazilian courts assert jurisdiction over divorce proceedings when any of the following conditions are met:

1. Last marital domicile in Brazil (CPC Art. 21, I): If the couple’s last shared residence was in Brazil, Brazilian courts have jurisdiction regardless of either spouse’s nationality.

2. Defendant domiciled in Brazil (CPC Art. 21, II): If the spouse being served (the defendant/réu) is domiciled in Brazil, Brazilian courts can hear the case even if the plaintiff lives abroad.

3. Plaintiff domiciled in Brazil (CPC Art. 21, III combined with LINDB Art. 7, §6): If the plaintiff has been domiciled in Brazil for at least one year, they can file for divorce in Brazil.

4. Brazilian nationality (LINDB Art. 7, §6): If either spouse is a Brazilian national, Brazilian courts have broader jurisdictional reach.

5. Brazilian real property at issue (CPC Art. 23, I): When the divorce involves division of Brazilian real property, Brazilian courts have exclusive jurisdiction over that property. No foreign court can adjudicate the division of a Brazilian apartment, house, or land.

When US Courts Have Jurisdiction

US divorce jurisdiction is state-based. Generally, a US state court has jurisdiction if:

• The filing spouse meets the state’s residency requirement (typically 6–12 months)
• The respondent spouse is domiciled in or has minimum contacts with the state
• The couple was married in the state (in some jurisdictions)

The Concurrent Jurisdiction Problem

In most US-Brazil binational divorces, both countries have jurisdiction simultaneously. This creates a strategic choice:

Filing in Brazil is generally advantageous when:

• The majority of marital assets are in Brazil
• Brazilian property regime (comunhão parcial) favors your position
• Children are habitually resident in Brazil
• Your spouse has limited US assets or connections
• You want to avoid US discovery rules (which are broader and more expensive)

Filing in the US is generally advantageous when:

• Significant retirement accounts (401k, IRA, pension) need QDRO division
• US equitable distribution or community property rules favor your position
• Children are habitually resident in the US
• Your spouse has limited Brazilian assets
• You need US court enforcement mechanisms for support

Filing in both jurisdictions may be necessary when:

• Substantial assets exist in both countries
• Children have connections to both countries
• One spouse needs a QDRO in the US and property division in Brazil

“Strategic jurisdiction selection is the most consequential decision in a binational divorce. I’ve seen cases where filing in the wrong jurisdiction cost clients hundreds of thousands of dollars in unfavorable property division. A couple with a R$3 million apartment in Jardins and a $500,000 401(k) in the US needs coordinated proceedings in both countries — not a single filing that ignores half the marital estate.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

How Does Homologação de Sentença Estrangeira Work at the STJ?

When a divorce is obtained abroad — typically in a US state court — and one or both spouses have connections to Brazil, the first question is which of two doors applies, because the answer changes the timeline by a year or more.

A consensual foreign divorce needs no homologation. CPC art. 961, §5, in force since 18 March 2016, provides that “a sentença estrangeira de divórcio consensual produz efeitos no Brasil, independentemente de homologação pelo Superior Tribunal de Justiça”. It is annotated directly in the Brazilian civil registry, and §6 allows any judge to examine its validity if the question arises in a case within their jurisdiction. Before 2016 every foreign divorce required STJ homologation — which is why the older rule is still repeated so widely.

A contested foreign divorce does require homologation, as do foreign decisions on support, custody and the division of property — including the property provisions of an otherwise consensual decree. Those remain with the Superior Tribunal de Justiça (STJ).

Where homologation is required, the process is governed by CPC Articles 960–965 and the STJ’s internal rules. This process is governed by CPC Articles 960–965 and Resolução STJ nº 9/2005. Our page on getting your foreign divorce recognised in Brazil describes how we handle these petitions.

Requirements for Homologation

The STJ will homologate a foreign divorce judgment only if all of the following conditions are satisfied:

1. Competent foreign court: The US court that issued the judgment must have had proper jurisdiction under its own law. The STJ verifies this independently.

2. Proper service of process: Both parties must have been properly notified of the proceedings. If the Brazilian-domiciled spouse was not served in accordance with the Hague Service Convention or Brazilian law, homologation will be denied.

3. Final and unappealable judgment: The US divorce decree must be final (not subject to further appeal). Interlocutory or provisional orders generally cannot be homologated.

4. No violation of Brazilian public policy (ordem pública): The foreign judgment cannot contradict fundamental principles of Brazilian law. This is where most disputes arise.

5. Apostille and sworn translation: The US judgment must bear an apostille under the Hague Apostille Convention and be translated into Portuguese by a sworn translator (tradutor juramentado).

What the STJ Will and Will Not Homologate

The STJ will homologate:

• The dissolution of the marriage itself (the divorce decree)
• Spousal support obligations stated in the US judgment
• Custody and visitation provisions (subject to best-interests review)
• Division of US-located assets as stated in the judgment

The STJ will NOT homologate:

• Provisions purporting to divide Brazilian real property (exclusive jurisdiction of Brazilian courts under CPC Art. 23)
• Provisions that violate Brazilian forced heirship rules
• Provisions that contravene Brazilian public policy on child welfare
• Provisional or non-final orders

Critical implication: If your US divorce decree says “Husband receives the São Paulo apartment,” that provision will not be enforced in Brazil through homologation. You need a separate Brazilian proceeding — either a consensual partition agreement registered at a cartório, or a judicial action for property division (ação de partilha) — to actually transfer Brazilian real property. This is one of the most common and costly mistakes in binational divorce.

Timeline and Costs of Homologation

• Filing: Petition filed at STJ in Brasília with all supporting documents
• PGR review: The Procuradoria-Geral da República (federal prosecutor) reviews and issues an opinion
• STJ decision: A minister of the STJ reviews and issues a decision
• Timeline: 6–18 months (complex cases with contested service or public policy arguments take longer)
• Costs: R$5,000–R$15,000 in legal fees plus R$1,500–R$4,000 in translation and filing costs

“Homologation at the STJ is not a rubber stamp. I’ve seen US divorce decrees rejected because the American court purported to divide a Brazilian beach house — something only a Brazilian court can do. I’ve also seen homologation denied because the Brazilian spouse was served by publication in a US newspaper, which the STJ found inadequate under Brazilian due process standards. Every detail of the US proceeding matters for Brazilian recognition.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

How Is Property Divided in a Binational Divorce?

Property division in a binational divorce is governed by the intersection of Brazilian marital property regimes and the lex rei sitae principle (property is governed by the law of the jurisdiction where it is located).

Step 1: Determine the Applicable Marital Property Regime

Under LINDB Article 7, §4, the marital property regime is determined by the law of the country where the couple was domiciled at the time of marriage. This creates different scenarios:

Married in Brazil (or domiciled in Brazil at marriage): Brazil’s default regime — comunhão parcial de bens (partial community of property) under Civil Code Articles 1.658–1.666 — applies unless the couple signed a pacto antenupcial (prenuptial agreement) choosing a different regime.

Married in the US (domiciled in a US state at marriage): The property regime of the US state applies. In community property states (California, Texas, Arizona, etc.), assets acquired during marriage are community property. In equitable distribution states (New York, Florida, etc.), assets are divided equitably (not necessarily equally).

Married in a third country: The property regime of the country of domicile at marriage applies.

Step 2: Apply Lex Rei Sitae to Brazilian Assets

Regardless of the applicable marital property regime, Brazilian real property is always divided under Brazilian law. This principle is established in CPC Article 23, I and LINDB Article 8.

Practical implications:

• An apartment in São Paulo is divided under Brazilian community property rules, even if the couple married in New York under New York equitable distribution principles
• A ranch in Goiás is divided under Brazilian rules, even if the couple signed a California prenup
• Brazilian bank accounts and investment accounts held at Brazilian financial institutions follow Brazilian rules

Step 3: Address Foreign Assets Separately

US assets — real property, bank accounts, retirement accounts, brokerage accounts — are generally governed by US law. Brazilian courts typically defer to US courts on the division of US-located assets, though they may consider the value of US assets when calculating offsets or compensating adjustments in the Brazilian proceeding.

The Prenuptial Agreement Complication

Foreign prenuptial agreements present unique challenges in Brazilian courts. Under Brazilian law, prenuptial agreements (pacto antenupcial) must be registered at a Cartório de Registro Civil to be effective against third parties. A US prenup was not registered in Brazil.

Brazilian courts will generally enforce a US prenup if:

• It was validly executed under US state law
• Both parties had independent legal counsel (or knowingly waived it)
• There was full financial disclosure
• The agreement does not violate Brazilian public policy

Brazilian courts will NOT enforce a US prenup if:

• It purports to eliminate a spouse’s meação (50% share of community property under comunhão parcial)
• It violates forced heirship rules for estate planning purposes
• There is evidence of duress, fraud, or unconscionability
• The agreement was not translated and presented to the Brazilian court

For detailed prenuptial analysis, see our guide on prenuptial agreements in Brazil, which covers foreign prenups as well.

Property Division Case Walkthrough (Anonymized)

An American husband and Brazilian wife married in Florida in 2012 under Florida equitable distribution rules (no prenup). They moved to São Paulo in 2016. During marriage, they acquired a R$2.8 million apartment in Itaim Bibi, a R$600,000 beach house in Ubatuba, a US brokerage account worth $420,000, and husband’s 401(k) worth $380,000.

Division approach: We filed for divorce in São Paulo. The Brazilian court applied comunhão parcial de bens to the Brazilian real property (acquired during marriage = community property, divided equally). For the US assets, we coordinated with Florida counsel who filed a supplemental action for equitable distribution of the brokerage account and a QDRO for the 401(k). The Brazilian judgment addressed only Brazilian assets; the US proceeding addressed only US assets. Total legal fees across both jurisdictions: approximately R$85,000.

How Are US Retirement Accounts (401k, IRA, Pension) Handled?

US retirement accounts are among the most complex assets in a binational divorce because they sit at the intersection of US tax law (ERISA, IRC §401), US domestic relations law (QDROs), and Brazilian marital property law.

The Core Problem

Brazilian courts cannot directly order a US financial institution to divide a 401(k) or IRA. US plan administrators will only accept a Qualified Domestic Relations Order (QDRO) issued by a US state court. A Brazilian divorce decree — even if homologated by the STJ — is not a QDRO.

The Solution: Coordinated Dual-Jurisdiction Approach

1. In the Brazilian proceeding: The 401(k)/IRA value is disclosed and considered part of the marital estate. The Brazilian court may award compensating Brazilian assets to the non-account-holding spouse (e.g., a larger share of the São Paulo apartment to offset the 401(k) the other spouse retains).

2. In the US proceeding: A US family law attorney files for a QDRO with the appropriate US state court. The QDRO directs the plan administrator to divide the account according to the divorce settlement.

3. Coordination: The Brazilian and US proceedings must be coordinated to avoid double-counting. If the Brazilian court awards the wife a compensating share of Brazilian real estate equivalent to her 401(k) interest, the US QDRO should not award her another share of the 401(k).

Pension and Social Security

• US pensions: Divisible via QDRO (for ERISA-covered plans) or court order (for government pensions under different statutes)
• US Social Security: Not divisible in divorce, but an ex-spouse married 10+ years may claim benefits on the former spouse’s record
• Brazilian INSS benefits: Not divisible but may be considered when calculating spousal support obligations
• Private Brazilian pension (previdência privada): Divisible as a marital asset under comunhão parcial if contributions were made during the marriage

How Does Spousal Support (Alimentos) Work Across Borders?

Brazilian courts may award spousal support (alimentos) under Civil Code Articles 1.694–1.710. The support determination considers:

• Duration of the marriage
• Each spouse’s earning capacity, age, and health
• Standard of living during the marriage
• Caretaking responsibilities (especially for children)
• Each spouse’s assets and income

Cross-Border Enforcement Challenges

Enforcing Brazilian spousal support in the US: Brazil is not a party to the Hague Convention on International Recovery of Child Support and Other Forms of Family Maintenance (2007), though the US ratified it in 2017. Enforcement requires registering the Brazilian judgment in a US state court under the Uniform Interstate Family Support Act (UIFSA) as adapted for international cases, or filing a new action in the US.

Enforcing US spousal support in Brazil: A US support order must be homologated by the STJ before it can be enforced in Brazil. Once homologated, Brazilian enforcement mechanisms apply — including wage garnishment, asset seizure, and even imprisonment for willful non-payment of family support obligations (alimentos are one of the few debts for which Brazilian law permits imprisonment under CF Art. 5, LXVII). Child support follows its own treaty routes, set out on our child support enforcement in Brazil page.

“Enforcement is the hidden crisis of binational divorce. A beautifully drafted settlement means nothing if you can’t collect. When the payor spouse lives in one country and the payee in another, enforcement requires active coordination between legal systems that don’t naturally talk to each other. I always build enforcement mechanisms directly into the settlement — Brazilian bank guarantees, US wage assignments, reciprocal contempt provisions — so there’s a clear path to collection if payment stops.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

How Does Child Custody Work in a US-Brazil Binational Divorce?

Child custody in a binational divorce is governed by the child’s habitual residence — a concept derived from the 1980 Hague Convention on the Civil Aspects of International Child Abduction, to which both the US and Brazil are signatories.

Determining Habitual Residence

The child’s habitual residence determines which country’s courts have primary jurisdiction over custody. Habitual residence is determined by factors including:

• Where the child has lived for the longest continuous period
• Where the child attends school
• Where the child has social connections (friends, extended family, community)
• The parents’ shared intent regarding the child’s residence
• The child’s own sense of home (for older children)

If the child is habitually resident in Brazil: Brazilian courts have primary custody jurisdiction. The Brazilian court applies the melhor interesse da criança (best interests of the child) standard under ECA (Estatuto da Criança e do Adolescente), Lei nº 8.069/1990 and Civil Code Articles 1.583–1.590.

If the child is habitually resident in the US: US courts have primary jurisdiction under the UCCJEA (Uniform Child Custody Jurisdiction and Enforcement Act).

The Hague Convention and International Child Abduction

Both the US and Brazil are parties to the 1980 Hague Convention. If one parent removes a child from their country of habitual residence without the other parent’s consent or a court order:

• The left-behind parent can petition for the child’s immediate return to the country of habitual residence
• In Brazil, the ACAF (Autoridade Central Administrativa Federal) processes Hague return petitions
• In the US, the Office of Children’s Issues at the State Department handles incoming and outgoing petitions
• Return is generally ordered unless narrow exceptions apply (grave risk of harm, child’s objection if of sufficient age and maturity, settlement in the new country for more than one year)

Critical warning for parents: Taking a child from Brazil to the US (or vice versa) without the other parent’s written consent or a court order authorizing the relocation is treated as international child abduction under the Hague Convention. This triggers criminal proceedings, mandatory return orders, and lasting damage to the abducting parent’s custody position. Always obtain judicial authorization before any international relocation with a child.

For detailed guidance on cross-border custody, see our guide to international child custody.

Shared Custody (Guarda Compartilhada) in Binational Families

Brazil’s Lei nº 13.058/2014 established shared custody (guarda compartilhada) as the default arrangement, meaning both parents share decision-making authority even if the child resides primarily with one parent.

In binational families, shared custody creates practical challenges:

• How do parents in different countries share educational decisions?
• Who bears international travel costs for visitation?
• How are school holiday schedules coordinated across countries with different academic calendars?
• What communication methods are required (video calls, messaging)?
• What happens if the primary custodial parent wants to relocate within the non-primary parent’s country?

Best practice: The custody agreement should address these specifics explicitly. I draft binational custody agreements that include detailed visitation schedules calibrated to both countries’ school calendars, allocation of airfare costs, communication protocols, passport custody provisions, and relocation notification requirements.

Custody Case Walkthrough (Anonymized)

An American father and Brazilian mother divorced in São Paulo after 8 years of marriage. Two children (ages 5 and 8) had lived their entire lives in Brazil. The father planned to return to the US; the mother would remain in São Paulo.

Custody arrangement: The court awarded guarda compartilhada (shared custody) with primary residence with the mother in São Paulo. The agreement provided: father receives children for 6 weeks in summer (US schedule), 2 weeks at Christmas/New Year, and 1 week at Easter; father bears 100% of airfare costs; weekly video calls on a fixed schedule; neither parent may relocate internationally without 90 days’ written notice and judicial authorization; children’s passports held by mother with release for agreed travel dates.

Divorce Itself Has No Waiting Period and No Fault Requirement

One point regularly surprises foreign spouses, particularly those from jurisdictions with separation periods. Since Emenda Constitucional nº 66/2010, CF art. 226, §6 reads simply: “O casamento civil pode ser dissolvido pelo divórcio.” The previous requirement of one year’s judicial separation or two years’ separation in fact was removed, and no statement of cause or fault is needed. Nobody has to prove anything about the other spouse’s conduct in order to be divorced.

Two things are commonly confused with this. Separação consensual at a notary — a different and now largely disused institution — still carries a one-year-of-marriage requirement under Res. CNJ 35/2007, art. 47. And fault can still matter to ancillary questions, such as the measure of support, even though it is irrelevant to the dissolution itself.

Where in Brazil the Case Is Filed

Once Brazilian jurisdiction is established, venue is a separate question and it has practical consequences for cost and speed. The general rule favours the domicile of the guardian of the couple’s children; failing that, the last common domicile; failing that, the domicile of the respondent. Where the parties agree and the case is consensual, the practical answer is usually the registry or the court district where the documents and the assets already are. Getting venue wrong produces a redistribution order and a lost quarter.

What Are the Types of Divorce Available in Brazil?

Consensual Divorce (Divórcio Consensual)

When both spouses agree on all terms — property division, custody, spousal support — Brazil allows a streamlined divorce process:

• Extrajudicial (cartório): If no minor children are involved and both spouses consent, the divorce can be finalized at a notary office (cartório) in 30–60 days. Governed by Lei nº 11.441/2007.
• Judicial consensual: If minor children are involved, the divorce must go through a judge but proceeds on an expedited track. Timeline: 3–6 months.
• No fault required: Brazil eliminated fault-based divorce with EC nº 66/2010. Neither spouse needs to prove infidelity, abandonment, or misconduct.

For binational couples: Consensual divorce is almost always preferable. A negotiated settlement that addresses Brazilian assets, US assets, custody, and support in a coordinated framework saves enormous time and cost compared to litigation. See our comparison of consensual vs. contested divorce in Brazil.

Litigious Divorce (Divórcio Litigioso)

When spouses cannot agree, one files a petition and litigation proceeds:

• Timeline: 1–3 years for first instance; appeals add 6–18 months
• Discovery: Brazilian discovery is narrower than US litigation but includes document production, expert appraisals, and witness testimony
• Expert valuations: Courts routinely appoint expert appraisers (peritos) for real estate and business valuations
• Costs: R$15,000–R$80,000+ in legal fees, plus R$3,000–R$15,000 in court costs and expert fees

See our comparison of judicial vs. extrajudicial divorce.

What Divorce Does to a Residence Permit

For the foreign spouse who lives in Brazil on a family-reunion basis, the divorce is also an immigration event, and it is better planned than discovered.

A temporary family-reunion authorisation (code 285) is conditioned on the family bond, not on the expiry date printed on the CRNM. When the bond is dissolved, the basis for the authorisation goes with it, whatever the card says. A permanent, indefinite-term residence (code 286) that has already been granted is a far more durable position.

The practical consequence is that a foreign spouse contemplating divorce should establish, before anything is filed or signed, whether they hold 285 or 286, and — if 285 — what independent ground would support their continued residence: their own employment or business, a Brazilian child, or the conversion to indefinite-term residence if it is still available on the existing bond. The same sequencing point applies to the reduced one-year naturalisation clock for the spouse or companion of a Brazilian (Lei 13.445/2017, art. 66, III), which requires the couple not to be separated at the moment the naturalisation is granted.

The change of civil status should in any event be reported to the Federal Police with the divorce properly annotated in the civil registry.

Taxes on the Partition Itself

Dividing the marital estate is not, in principle, a taxable transfer — each spouse is taking what the regime already allocated to them. Two taxes appear when the division departs from that line:

• ITCMD, the state gift and inheritance tax, where one spouse receives more than their share and the excess is gratuitous — a donation in substance.
• ITBI, the municipal transfer tax, where the excess is compensated — paid for, in cash or by offset against another asset.

Rates, bases and exemptions are set by the state and the municipality respectively, and they differ. A partition drafted without modelling the excess is the commonest way a “amicable” settlement produces an unexpected assessment months later. Where Brazilian real property is being partitioned after a divorce abroad, see dividing Brazilian property in a foreign divorce.

How Can You Enforce a Divorce Judgment Across Borders?

Enforcing a Brazilian Judgment in the US

A Brazilian divorce decree does not automatically have legal effect in the US. To enforce it:

1. Register the judgment in the appropriate US state court (procedure varies by state)
2. Comity doctrine: US courts generally recognize foreign judgments under principles of comity, but the losing party can challenge recognition on grounds of lack of jurisdiction, inadequate notice, or public policy violation
3. For property division: If the Brazilian judgment awards US-located assets, registration in the relevant US state is required
4. For support: Registration under UIFSA for ongoing enforcement

Enforcing a US Judgment in Brazil

1. Homologation at STJ: Required for the judgment to have effect in Brazil (see above)
2. Post-homologation enforcement: Once homologated, the judgment is enforceable through Brazilian execution proceedings (execução)
3. Asset seizure: Brazilian courts can freeze and seize bank accounts, garnish wages, and attach real property
4. Imprisonment for non-payment of alimentos: Willful non-payment of family support obligations can result in imprisonment (civil detention) under CF Art. 5, LXVII — one of the strongest enforcement tools available globally

What Else Decides the Outcome: Regimes, Support and Settlement Practice

Jurisdiction and asset location set the frame of a binational divorce. Within that frame, three further questions decide what the client actually walks away with: which property regime governs the marriage, how the court sets support, and whether the case settles or is litigated to judgment. None of these is a matter of advocacy skill alone; each turns on rules a foreign spouse can be told in advance.

The four Brazilian property regimes

Brazilian law recognises four marital property regimes, set out in the Civil Code at Articles 1.639 to 1.688. Where LINDB Article 7 points to Brazilian law, one of these four governs, and identifying which one is the first analytical step in any division of Brazilian assets.

Comunhão parcial de bens (partial community) is the default where the couple signed no pacto antenupcial. Assets acquired during the marriage are shared equally; assets owned before it remain individual, as do inheritances and gifts received during it.

Comunhão universal de bens (universal community) pools everything — pre-marital property, inheritances and gifts included — subject to narrow exceptions such as assets held under a fideicomisso and items of personal use. It must be elected by prenuptial agreement.

Separação total de bens (total separation) leaves each spouse with their own property, with no sharing on dissolution. It too must be elected by prenuptial agreement, and it is imposed by law where one of the spouses is over seventy.

Participação final nos aquestos (final participation in acquired assets) lets each spouse manage their own property during the marriage while dividing net acquisitions equally on dissolution. It is rarely chosen in practice.

For a foreign spouse the practical point is that the regime is not an argument the court weighs. It is a rule the court applies. A Brazilian judge does not decide what division would be fair in the circumstances of the marriage, as a court in England or in a US equitable-distribution state might; the judge identifies the regime and applies its arithmetic to the Brazilian estate. That is why the analysis under LINDB Article 7 is worth doing carefully at the outset rather than arguing about later.

How Brazilian courts set support

Spousal support (pensão alimentícia) between former spouses is not automatic and must be claimed. The court weighs the claimant’s need (necessidade), the payer’s capacity (possibilidade) and proportionality against the standard of living during the marriage. There is no statutory formula, and awards in practice have tended to fall in a band around a fifth to a third of the payer’s net income, but that is an observed range rather than a rule a court is bound by.

The more consequential trend is in duration. Brazilian courts increasingly award alimentos transitórios — support for a defined period, commonly a small number of years, intended to carry the receiving spouse to self-support — rather than open-ended maintenance. Indefinite support is now largely reserved for cases where age, health or a long absence from paid work makes self-support unrealistic. A foreign spouse who relocated to Brazil for the marriage and gave up a career abroad is squarely within the situation transitional support is designed for, and the evidence for that claim is documentary: the employment history before the move, the visa status, the caretaking arrangements the couple adopted.

Child support is a separate obligation from spousal support and is not extinguished by any agreement between the parents. It covers food, housing, schooling, health, clothing and transport, and it runs until the child reaches eighteen, or later — commonly to twenty-four — where the child is in higher education. Enforcement is the part foreign clients underestimate: unpaid family support is one of the few civil debts for which Brazilian law permits detention of the debtor, under the procedure in CPC Article 528, for a period the court fixes in months. That tool exists on both sides of a binational case and is a material consideration when deciding where a support order should be obtained.

Mediation is an offer the court must make

Since the 2015 Code of Civil Procedure, a Brazilian family court is required to schedule a conciliation or mediation hearing before the adversarial phase begins (CPC Article 694). For binational couples this is more useful than it is for most Brazilian ones, for reasons that have nothing to do with sentiment:

• A mediation can be conducted in English, or with an interpreter, in a way a formal hearing cannot. The foreign spouse can follow and participate in the discussion that decides their case.
• A mediator can hold two sets of legal expectations in the room at once — what a US or European client assumes about spousal maintenance, what Brazilian law actually provides — and reconcile them, which a judgment cannot do.
• It compresses the calendar. A mediated settlement is measured in sessions over weeks; a contested first-instance judgment is measured in years, and appeals add to that.

State courts maintain registers of accredited mediators, and private chambers also take family matters. Counsel who dismisses mediation without giving a substantive reason is either unfamiliar with the current procedure or has a different interest in the case.

Running the case from abroad

Physical presence in Brazil is not required for most of a divorce. A power of attorney (procuração), signed at a Brazilian consulate or before a local notary and apostilled, allows Brazilian counsel to act throughout a judicial divorce, and remote hearings are now routine. The extrajudicial route at a notary’s office requires the parties or their specially empowered representatives to appear.

One preliminary step catches couples who married abroad and now wish to divorce in Brazil: the foreign marriage must first be transcribed in the Brazilian civil registry. That requires the marriage certificate apostilled in the country of issue and translated by a sworn translator registered in Brazil, and the registry fees and translation costs are paid to those authorities and professionals, not to counsel. It is a short step, but it has to be finished before the divorce petition can proceed, and it is better started at the first consultation than discovered at filing.

Protecting yourself against a case that never settles

Contested family litigation rewards duration. That is a structural feature of any market in which work is billed by the hour and the client cannot readily assess whether a step was necessary, and foreign clients are more exposed to it than local ones: they are less able to judge whether a motion was required, they cannot easily read the file, and they are often not in the country. The protections are contractual and procedural, and they should be agreed at the outset rather than raised once the relationship has soured.

• Put the scope in writing. The engagement letter should state what is included, what is billed separately, and what triggers a change in the arrangement. An open-ended instruction is the condition in which drift happens.
• Ask for itemised billing. Each statement should say what was done, on what date, and what it produced. “Professional services rendered” is not a description, and the OAB’s professional rules require a lawyer to be clear with the client about the basis of the charge.
• Prefer milestones to duration. Where the nature of the work allows it, tying the arrangement to defined stages — petition filed, asset disclosure complete, settlement agreement executed, judgment obtained — aligns the lawyer’s interest with reaching those stages rather than with the passage of time.
• Ask for settlement positions in writing. If counsel advises rejecting an offer from the other side, the reasoning should be recorded: which terms are deficient, by reference to what the applicable regime or the support rules would produce. A reasoned rejection is easy to give; its absence is informative.
• Ask about the path to agreement at the first meeting. The first question a family practitioner should ask is whether a consensual resolution is available and on what terms. Where the answer is an immediate move to litigation, it is fair to ask why.
• Check standing with the OAB. Registration and good standing can be verified directly with the relevant state section of the Ordem dos Advogados do Brasil, as set out in our guide to verifying a Brazilian lawyer’s credentials.

Why ZS Advogados for Your Binational Divorce?

This is my signature practice area. As an American who moved to Brazil at 18, became the first American admitted to the OAB, and built a binational family of my own, I understand the pressures of cross-border marriage and divorce at a personal level. My USC LL.M. in international family law and my daily practice representing American, European, and other foreign spouses in Brazilian courts give me a combination of technical knowledge and cultural fluency that is difficult to replicate.

I do not treat binational divorce as a routine family law matter with international complications. I treat it as a multi-jurisdictional strategic engagement that requires understanding both legal systems — how Brazilian judges think about property division, how US courts handle QDROs, how the STJ evaluates homologation petitions, and how the Hague Convention applies to custody disputes in practice.

What we do:

• Jurisdictional analysis and strategic forum selection
• Consensual divorce negotiation and drafting (bilingual settlement agreements)
• Contested divorce litigation in Brazilian courts
• Homologação de sentença estrangeira at the STJ
• Cross-border property division coordinated with US counsel
• QDRO coordination for US retirement account division
• Hague Convention custody proceedings (both return applications and defense)
• Spousal support negotiation and cross-border enforcement
• Coordination with estate planning for post-divorce asset protection
• Coordination with binational family structuring
