Arbitration & Mediation in Brazil

You signed a commercial contract that includes an arbitration clause. Now a dispute has arisen, and both parties are considering whether to pursue arbitration or court litigation. Or you want to preserve a business relationship while resolving a conflict—mediation might be the path. Brazil has modern arbitration and mediation frameworks that offer alternatives to slow, public court litigation. Understanding these options, their enforceability, and their cost-benefit compared to court can determine not just whether you win, but whether the process bankrupts you or preserves your relationship. This guide explains Brazilian arbitration and mediation law, the major arbitration centers, and when each approach makes business sense. For international arbitration across borders, see international arbitration and contract disputes.

Arbitration in Brazil: Lei de Arbitragem (Law 9.307/1996)

Brazil’s Lei de Arbitragem (Arbitration Law) is modern, sophisticated, and modeled on international best practices. It permits private parties to submit disputes to a neutral arbitrator (or panel of arbitrators) instead of state courts.

What is Arbitration?

Arbitration is a consensual dispute resolution process where:

• Parties agree to submit their dispute to one or more neutral arbitrators (instead of a judge)
• Arbitrators are chosen by the parties (often selecting arbitrators with technical expertise in the subject matter)
• Proceedings are private and flexible (parties set rules, schedule, and location)
• Award is final (very limited grounds for appeal or challenge)
• Award is enforceable internationally under the New York Convention (1958)

When Does Arbitration Apply?

Valid Arbitration Agreements

An arbitration clause is valid if:

• Written — Must be in writing (email, contract, letter, or signed agreement)
• Clear intention — Both parties explicitly agree to arbitrate disputes
• Future disputes — Parties can agree to arbitrate future disputes (e.g., clause in contract)
• Existing disputes — Parties can agree to arbitrate a dispute that has already arisen (compromise agreement)

Examples:

• “Any disputes arising from this contract shall be submitted to arbitration under CAM-CCBC rules”
• “The parties agree to resolve disputes via JAMS arbitration in New York”
• After a dispute arises: “We agree to arbitrate this dispute with an arbitrator selected by mutual consent”

Disputes That Cannot Be Arbitrated

• Familial matters — Divorce, custody, inheritance (though not absolute; some family-related commercial disputes can be arbitrated)
• Labor disputes — Disputes between employer and employee (though individual worker agreements may be arbitrable in limited cases)
• Criminal matters — Arbitration cannot resolve criminal liability
• Public policy matters — Some disputes involving public rights cannot be arbitrated (though scope is narrow)

Practical note: Most commercial contract disputes are arbitrable in Brazil, including disputes over payment, performance, damages, and even non-compete violations.

Steps in a Brazilian Arbitration

Step 1: Initiation

One party sends a notice to arbitrate (notificação para arbitragem) to the other party or files a request for arbitration with an arbitration center:

• Notice must specify: Dispute subject, relief sought, and request to proceed with arbitration
• Timeline: Arbitration begins immediately upon notice (no court filing needed)

Step 2: Selection of Arbitrator(s)

The parties select arbitrator(s):

Single arbitrator:

• Used for smaller disputes or if parties agree
• Faster and less expensive

Panel (usually 3 arbitrators):

• Used for larger or more complex disputes
• Each party selects one arbitrator; those two select the third (president)
• More comprehensive analysis; slower

Institutional arbitration (through arbitration center like CAM-CCBC):

• Parties don’t select arbitrators themselves
• Center has roster of arbitrators; parties nominate preferences
• Center’s panel management adds formality and oversight

Step 3: Procedural Rules

The arbitration agreement specifies procedural rules:

• Brazilian rules — e.g., CAM-CCBC or FIESP rules
• International rules — e.g., UNCITRAL Arbitration Rules
• Custom rules — Parties can agree to any rules they prefer
• Default — If no rules specified, Lei de Arbitragem default rules apply

Typical procedural steps:

1. Filing of claims and counterclaims (written submissions)
2. Evidence exchange (documents, expert reports)
3. Hearing(s) with oral testimony and argument
4. Deliberation by arbitrator(s)
5. Issuance of award (written decision)

Step 4: The Hearing

The hearing in arbitration is typically flexible and efficient:

• Single or multiple sessions — Parties decide length and number of hearings
• Confidential — Proceedings are private; only parties and arbitrators present
• Flexible schedule — No court calendar constraints
• Expert arbitrators — Arbitrators often understand the technical or industry issues (engineers, accountants, builders, etc.)
• Expedited procedures — For small claims, abbreviated procedures can be used (1–2 month timeline)

Step 5: The Award (Sentença Arbitral)

The arbitrator(s) issue a written award containing:

• Findings of fact — What happened
• Legal conclusions — Which party breached, liability, damages
• Ruling — Who wins, what they’re owed
• Costs allocation — Usually the losing party pays arbitrator fees and legal costs

Finality: The award is final and binding. Unlike court judgments, arbitration awards cannot be appealed on the merits.

Step 6: Enforcement

If the losing party doesn’t pay the award:

• Homologation — File the award with a Brazilian court for official recognition (quick, usually granted)
• Execution — Court enforces the award like a judgment (seize assets, garnish wages, etc.)
• International enforcement — Under the New York Convention, the award can be enforced in over 170 countries

Timeline for Arbitration

Type	Duration
Expedited (small claims)	2–4 months
Standard institutional	6–12 months
Complex commercial	12–18 months
Large international	18–24 months

Comparison to court: Court litigation in Brazil typically takes 1–2.5 years for first instance alone, plus possible appeals. Arbitration is generally faster.

Costs of Arbitration

Arbitrator Fees

Fees are set by the arbitration center or agreed by parties:

CAM-CCBC Fees (Example):

• Small claims (< R$ 100,000): R$ 5,000–15,000 total arbitrator fees
• Medium claims (R$ 100,000–1,000,000): R$ 15,000–50,000
• Large claims (> R$ 1,000,000): R$ 50,000–200,000+

Solo arbitrator: Typically 20–30% lower than panel fees

International arbitration (e.g., ICC, LCIA, UNCITRAL): Usually higher; R$ 20,000–500,000+ depending on complexity and amount in dispute

Legal Fees

• Simple arbitration: R$ 15,000–40,000
• Moderate complexity: R$ 40,000–100,000
• High complexity: R$ 100,000–300,000+

Administrative Costs

• Filing fees: R$ 2,000–5,000
• Hearing room rental (if not at arbitration center): R$ 1,000–3,000 per day
• Expert witnesses: R$ 5,000–30,000 per expert
• Translations: R$ 2,000–8,000

Total Estimated Arbitration Costs

Dispute Value	Low	High
R$ 100,000	R$ 8,000	R$ 25,000
R$ 500,000	R$ 25,000	R$ 80,000
R$ 2,000,000	R$ 50,000	R$ 150,000

Comparison: Arbitration is typically 20–40% cheaper than court litigation for equivalent disputes due to faster timeline and efficiency.

Mediation in Brazil: Lei da Mediação (Law 13.140/2015)

Mediation is a facilitated negotiation where a neutral third party (mediator) helps disputing parties reach their own agreement. Unlike arbitration, the mediator doesn’t decide the dispute—the parties do.

What is Mediation?

Mediation involves:

• Neutral facilitator — Mediator has no decision-making authority; only helps communication
• Party autonomy — Parties themselves create the solution
• Confidentiality — Mediation sessions are confidential; nothing said can be used in court later
• Non-binding — Unless parties reach agreement, there is no award or decision
• Preservation of relationship — Mediation prioritizes maintaining business or personal relationships

When Should You Mediate?

Mediation works best when:

• Relationship matters — You want to preserve the business relationship
• Communication has broken down — Parties have stopped talking; mediator reopens dialogue
• Multiple issues — Dispute involves multiple facets (payment, delivery, quality, relationship) where creative solutions exist
• Emotions high — Mediation helps move past anger/blame to focus on interests
• Speed essential — You need resolution urgently (mediation is fast)
• Cost critical — You can’t afford months of litigation or arbitration

Mediation may not work when:

• One party is not interested in settlement — If defendant refuses to engage, mediation fails
• Clear right/wrong needed — You need a judge or arbitrator to declare you right (e.g., for precedent)
• Defendant has no assets — Even successful mediation requires defendant to have resources to pay

Process of Mediation (Lei 13.140/2015)

Step 1: Initiating Mediation

• Mutual agreement — Both parties agree to mediate (in writing)
• Court-ordered — Judge may order mediation in pending litigation
• Mediator selection — Parties select from roster of certified mediators, or court appoints
• First session scheduled — Mediator meets with parties

Cost: R$ 1,000–5,000 per session (varies by mediator and complexity)

Step 2: Information Gathering

Mediator meets with each party separately (confidential caucuses) to understand:

• Each party’s interests — What do you really need? (Not just the legal claim, but underlying interests)
• Constraints — What are your walk-away points?
• Solutions brainstorming — What might work?

Mediator identifies common ground and areas of disagreement.

Step 3: Negotiation Sessions

Mediator facilitates joint or separate sessions where parties:

• Exchange information — Each side explains their position
• Reality-test — Mediator helps parties evaluate strength of their case
• Generate options — Mediator suggests compromises or creative solutions
• Bargain — Parties move toward agreement

Number of sessions: Typically 2–6 sessions over 2–8 weeks

Step 4: Agreement or Impasse

If agreement is reached:

• Parties sign a settlement agreement (termo de acordo)
• Agreement is binding (enforceable like a contract)
• Agreement can be registered with court if there was pending litigation
• Dispute is resolved

If parties can’t agree:

• Mediation ends
• Either party can pursue litigation or arbitration
• Nothing said in mediation can be used in court (confidentiality protection)

Timeline for Mediation

Stage	Duration
Scheduling	1–2 weeks
Initial session	Week 1
Mediation sessions	2–6 weeks total
Total	2–8 weeks

Fastest dispute resolution option: Mediation can resolve disputes in weeks, compared to months (arbitration) or years (litigation).

Costs of Mediation

• Mediator fee: R$ 1,000–3,000 per session; average 4 sessions = R$ 4,000–12,000
• Lawyer representation (optional): R$ 3,000–10,000 (less than arbitration or litigation)
• Administrative costs: Minimal

Total: R$ 5,000–20,000 for a mediated dispute

Comparison: Mediation is the cheapest dispute resolution option.

Strategic Decision Framework

Choose Litigation if:

• You need a precedent-setting decision
• Defendant refuses alternative dispute resolution
• Public ruling would benefit your reputation
• You’re confident in your legal position
• You have the time and cost tolerance

Choose Arbitration if:

• Contract includes arbitration clause
• Speed is important
• Confidentiality is critical
• You want an expert arbitrator in your industry
• International enforceability needed
• You want finality (no appeals)

Choose Mediation if:

• You want to preserve the business relationship
• Quick resolution is critical
• Cost is a major concern
• Multiple interests (not just legal) are at stake
• You believe settlement is possible with help

Combine Approaches

• Mediation first, then arbitration — Try to settle via mediation; if unsuccessful, proceed to arbitration (common in commercial contracts)
• Litigation with settlement conference — Brazilian courts require mediation/settlement conference before trial anyway
• Negotiation + arbitration — Attempt negotiation; if unsuccessful, arbitrate per contract clause

Practical Checklist: Choosing Dispute Resolution

BEFORE DISPUTE ARISES
☐ Review all contracts for arbitration or mediation clauses
☐ Understand which jurisdiction/law applies
☐ If negotiating new contract, consider preferred dispute resolution
☐ Consider arbitration clause for international contracts (easier enforcement)
☐ Consider mediation clause for long-term relationships

IF DISPUTE ARISES
☐ Assess the dispute:
  ☐ How much is at stake? (influences cost-benefit of each approach)
  ☐ Is relationship important to preserve?
  ☐ How urgent is resolution?
  ☐ Do you need a public ruling or precedent?
  ☐ How complex is the dispute?

DISPUTE RESOLUTION STRATEGY
☐ Attempt negotiation/settlement directly (often fastest, cheapest)
☐ If unsuccessful, check contract for arbitration clause
  ☐ If arbitration clause exists: initiate arbitration
  ☐ If no clause: consider proposing mediation to other party
  ☐ If other party refuses ADR: prepare for court litigation
☐ Consider timing: Can you afford to wait 1–2 years (litigation)?
☐ Assess defendant's assets: Can you collect a judgment?

IF PURSUING ARBITRATION
☐ Notify other party of arbitration per contract
☐ Select arbitrator(s) or arbitration center
☐ Gather evidence and prepare statement of claim
☐ File with arbitration center (if institutional)
☐ Attend hearings and present evidence
☐ Await award (typically 6–18 months)

IF PURSUING MEDIATION
☐ Propose mediation to other party
☐ Select mediator
☐ Prepare for sessions (understand your interests, not just legal positions)
☐ Attend sessions (mediator guides process)
☐ Negotiate toward settlement
☐ If successful, formalize agreement; if not, pursue other avenues

IF PURSUING LITIGATION
☐ Consult litigation lawyer immediately
☐ Prepare complaint and evidence
☐ File with trial court
☐ Attend mandatory settlement conference (Brazilian courts require)
☐ Participate in trial
☐ Await judgment (1–2 years likely)
☐ Prepare for possible appeals
