Joint Custody in Brazil: Complete Guide for 2026
Direct Answer
Joint custody is the default rule in Brazil since Law 13,058/2014 and must be applied even when parents do not agree. Under this arrangement, both parents jointly exercise parental responsibilities — decisions about education, health, and upbringing — regardless of which parent the child primarily lives with. The judge will only grant sole custody in exceptional situations involving risk to the minor’s welfare. Learn more about our real estate law services.
What Is Joint Custody
Joint custody, established in arts. 1,583 and 1,584 of the Civil Code (as amended by Law 13,058/2014), is the joint exercise of parental authority by both parents. It differs fundamentally from alternating custody (equal time division) and sole custody (responsibility concentrated in one parent).
In practice, joint custody means:
- Both parents decide together about school, doctor, extracurricular activities
- The child has a primary residence but maintains regular contact with both parents
- Neither parent needs the other’s authorization for everyday decisions
- Major decisions require consensus or, failing that, a court ruling
Legislative Evolution

| 2008 | Law 11,698 | Regulation of joint custody |
| 2014 | Law 13,058 | Joint custody as mandatory default rule |
| 2022 | Law 14,340 | Procedural adjustments and child protection |
Types of Custody in Brazil
Joint Custody (Guarda Compartilhada)
Both parents jointly exercise parental authority. It has been the legal default since 2014. The child has a defined primary residence but spends time with both parents in a balanced arrangement.
Sole Custody (Guarda Unilateral)
Parental responsibility is assigned to only one parent. The other retains visitation rights and a duty to monitor the child’s well-being. Applicable only when joint custody is impractical or harmful to the child.
Grounds for sole custody (case law):
- Proven domestic violence
- Serious abuse or neglect
- Severe substance abuse without treatment
- Voluntary parental abandonment
- Proven risk to the minor’s welfare
Alternating Custody (Guarda Alternada)
Not expressly provided for in Brazilian legislation, alternating custody divides time equally (e.g., one week with each parent). It is controversial and rarely adopted by courts, which consider it potentially harmful to the child’s emotional stability.
Comparison of Custody Types
| Aspect | Joint | Sole | Alternating |
|---|---|---|---|
| Joint decisions | Yes | No | Yes |
| Fixed primary residence | Yes | Yes | No (alternates) |
| Legal default | Yes | Exception | Not provided |
| Balanced contact | Yes | Limited | Equal |
| Child stability | High | Medium | Variable |
Best Interest of the Child Principle
The best interest of the child principle (art. 227, Federal Constitution; art. 3, ECA) guides all custody decisions. The judge must consider:
- Affection and bonds — quality of the relationship with each parent
- Health and safety — each parent’s capacity to care for the child
- Stability — maintenance of school and social routines
- Family environment — living and cohabitation conditions
- Child’s wishes — heard when the child has appropriate age and maturity (art. 12, Convention on the Rights of the Child)
Social studies and psychological evaluations, conducted by the court’s multidisciplinary team, are essential tools supporting the judicial decision.
Visitation Schedule
The visitation schedule (regime de convivência) establishes how the child’s time will be distributed between parents under joint custody.
Common Models
Biweekly model: Alternating weekends (Friday to Sunday) with the non-residential parent, plus one or two days during the week.
Extended weekly model: Monday to Wednesday with one parent, Thursday to Sunday with the other, alternating biweekly.
Split vacation model: School vacations divided equally, with alternating extended holidays and commemorative dates.
Schedule Elements
- Days and times for transitions between residences
- Division of school vacations (July and December/January)
- Alternation of holidays and special dates
- Communication (phone calls and video calls)
- Transportation and logistics
Flexibility Clause
Including a flexibility clause in the agreement is recommended, allowing consensual adjustments without a new court proceeding. Excessive rigidity tends to generate conflicts and harm the coparenting relationship.
How to Request Joint Custody
In Consensual Separation
When there is agreement, joint custody is formalized in the agreement ratified by the judge or in the public divorce deed.
Required documents:
- Children’s birth certificates
- Proposed visitation schedule
- Child support agreement
- Proof of residence for both parents
In Litigious Separation
When there is no agreement, either parent may request joint custody in court. The judge will order social and psychological studies to evaluate the situation and establish the arrangement that best serves the child’s interest.
Procedure:
- Initial petition requesting joint custody
- Service of process on the other parent
- Conciliation hearing (art. 695, CPC)
- Social study and psychological evaluation
- Evidentiary hearing (if needed)
- Judgment establishing custody and visitation schedule
Custody Modification
Custody may be modified at any time when factual circumstances change. Art. 1,586 of the Civil Code authorizes review whenever the child’s interest so requires.
Grounds for Modification
- Relocation of one parent
- Change in health or financial conditions
- Proven parental alienation
- Repeated violations of the visitation schedule
- Adolescent’s expressed wishes
- New marriage or common-law union impacting visitation
Procedure
Modification must be requested through a custody modification action (art. 1,585, CC). The judge may grant urgent relief to provisionally change custody when there is imminent risk to the child.
Relocation
One of the most contentious issues in joint custody is relocation to another city or state by one parent. Brazilian case law establishes that:
- Relocation cannot be unilateral under joint custody
- The relocating parent must obtain consent from the other or court authorization
- The judge will evaluate the impact on the visitation schedule and the child’s best interest
- Unauthorized relocation may constitute breach of custody and even parental alienation
Factors Considered by the Court
- Reason for relocation (work, health, family)
- Distance and feasibility of maintaining visitation
- Child’s age and adaptability
- Support network in both locations
- Possibility of adjusting the visitation schedule
Child Support Under Joint Custody
Joint custody does not eliminate the child support obligation. Even with shared responsibilities, the parent with greater financial capacity must contribute proportionally to the children’s expenses.
The STJ has established that joint custody alone is not grounds for waiving or reducing child support (REsp 1,629,994/RJ). The amount follows the trinomial of need-ability-proportionality.
Division Methods
- Fixed support: Monthly amount set by court
- Proportional expense sharing: Each parent covers expenses proportional to their income
- Joint account: Deposits into a specific account for children’s expenses
- Mixed system: Fixed support plus sharing of extraordinary expenses
Consequences of Violating the Visitation Schedule
Violation of the visitation schedule by either parent can result in legal consequences:
- Search and seizure of the child (extreme measure)
- Fines (astreintes) for non-compliance with court orders
- Custody modification in favor of the affected parent
- Moral damages compensation to the parent and child
- Criminal liability for disobedience (art. 330, Criminal Code)
When to Consult an Attorney
Custody matters require specialized family law guidance. You should consult an attorney when:
- There is disagreement about the visitation schedule
- One parent intends to relocate
- Parental alienation is suspected
- Existing custody needs to be modified
- The established schedule is being violated
