How to Verify a Brazilian Lawyer's Credentials in 5 Steps

The Short Answer

Verifying a Brazilian lawyer takes less than five minutes using the OAB’s free ConfirmADV tool at confirmadv.oab.org.br. Search by name or OAB number, confirm their status shows “Regular,” check their registration type is “Advogado,” look for any disciplinary history, and verify any claimed specializations. Sao Paulo alone has logged over 1,600 complaints about people illegally practicing law — verification isn’t paranoia, it’s basic due diligence.

“Verification isn’t about being paranoid — it’s about being smart. In a country with over 1.3 million registered lawyers and thousands of unregistered people offering legal services, five minutes on ConfirmADV is the highest-return due diligence you’ll ever do.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

Why Verification Matters More in Brazil

Here’s something that surprised me when I first started practicing here: Brazil has over 1.3 million registered lawyers — more lawyers per capita than almost any country on earth. That’s the good news. The bad news is that the sheer volume means quality varies enormously, and the market attracts people who aren’t lawyers at all but claim to be.

In Sao Paulo state alone, the OAB’s Comissao de Combate ao Exercicio Ilegal da Profissao has received over 1,600 complaints about individuals practicing law without authorization. These aren’t just people who let their registration lapse. Some never attended law school. Others were disbarred and kept working. A few are outright fraudsters who collect fees and disappear.

As a foreigner, you’re a particularly attractive target because you may not know how to check credentials and you’re often dealing with urgent matters (visa deadlines, property closings) that create pressure to skip due diligence.

Step 1: Search on ConfirmADV

The OAB’s official verification tool is ConfirmADV. It’s free, public, and updated in real time.

How to search:

• By name: Enter the lawyer’s full name. Brazilian names are long — Maria da Silva Oliveira Santos is one person. Use the full name as given to you.
• By OAB number: The format is OAB/[STATE] [NUMBER]. For example: OAB/SP 351.356. Enter the state abbreviation and number.
• By CPF: If you have their CPF (Brazilian tax ID), you can search by that too.

What you’ll see:

The results page shows the lawyer’s full registration details. Here’s what to look for:

• Nome: Full legal name
• Numero de inscricao: OAB registration number
• Seccional: State of primary registration (SP, RJ, MG, etc.)
• Tipo de inscricao: Type of registration
• Situacao: Current status
• Data de inscricao: Registration date (tells you how long they’ve been practicing)

If your search returns no results, that’s an immediate disqualifier. Every practicing lawyer in Brazil must have an OAB registration. No exceptions.

Step 2: Understand the Status Codes

The Situacao field is the most important thing on the page. Here’s what each status means:

Regular

Active and in good standing. This is what you want to see. The lawyer has paid their annual dues, has no current suspensions, and is authorized to practice law in Brazil.

Licenciado

Voluntarily inactive. The lawyer has requested a leave of absence — common for those who enter government service, academia, or take time off. A licenciado lawyer cannot practice law or represent clients. If someone with this status offers to represent you, they’re violating OAB rules.

Suspenso

Suspended. This is a disciplinary action. The lawyer has been suspended from practice, typically for 30 days to 12 months, due to ethical violations. A suspended lawyer cannot practice law. Hiring one is both risky and potentially harmful to your case — any legal acts they perform may be challenged.

Cancelado

Registration permanently cancelled. This can happen due to serious disciplinary violations, a final criminal conviction, or the lawyer’s own request. Do not hire.

Excluido

Expelled from the OAB entirely. This is the most severe sanction. Do not hire under any circumstances.

Important nuance: A lawyer can be “Regular” in one state and have a different status in another if they hold multiple registrations. Always check the state where they’ll be representing you.

Step 3: Verify Registration Type

The Tipo de inscricao field tells you what kind of OAB registration the person holds:

• Advogado/Advogada: Full lawyer. This is what you need.
• Estagiario: Law student intern. They can assist a supervising lawyer but cannot represent you independently or sign legal documents on your behalf.
• Suplementar: A supplementary registration in a second state. This is fine — it means they’re registered in their home state and also registered where you need services.

I’ve seen cases where a law student intern presented themselves to foreign clients as a “lawyer” during consultations. The client had no way of knowing the difference because the intern was in a law office and spoke with confidence. Always check the tipo de inscricao.

Step 4: Check Disciplinary History

ConfirmADV shows current status but not full disciplinary history. For that, you need to take an extra step:

Option A: Request directly from the OAB Seccional Contact the OAB in the lawyer’s state and request a “certidao de regularidade” or “certidao de inteiro teor.” This is a certificate showing their full registration history, including any disciplinary proceedings. Any member of the public can request this, though some seccionais charge a small fee (R$20-50).

Option B: Ask the lawyer directly A straightforward approach: “Can you provide a certificate of good standing from the OAB?” Any ethical lawyer will comply without hesitation. Reluctance to provide this is a red flag.

Option C: Search public records OAB disciplinary proceedings that result in suspension or exclusion become public record. You can search for the lawyer’s name in the Diario da Justica Eletronica (electronic court gazette) of their state.

What disciplinary actions look like:

• Censura (Censure): A warning under OAB Code of Ethics Art. 36. Not great, but not disqualifying for a single occurrence.
• Suspensao (Suspension): Practice ban for a period under Estatuto da Advocacia Art. 37. Serious. Ask about the circumstances.
• Exclusao (Expulsion): Permanent under Estatuto Art. 38. Disqualifying.

A single censure from 10 years ago is different from a pattern of disciplinary issues. Context matters.

Step 5: Verify Claimed Specializations

Brazilian lawyers love to list specializations on their websites. But in Brazil, the term “especialista” has a specific legal meaning that most foreigners (and many Brazilians) don’t understand.

OAB-recognized specialist titles:

The OAB awards an official “Titulo de Especialista” in specific areas of law. To earn this, a lawyer must:

• Have at least 5 years of practice
• Pass an exam administered by the OAB’s National Council
• OR hold a recognized postgraduate degree in the specialty AND demonstrate practical experience

There are currently recognized specializations in areas like Direito Imigratario (Immigration Law), Direito Imobiliario (Real Estate Law), Direito Tributario (Tax Law), Direito Internacional (International Law), and others.

What this means in practice:

• A lawyer can claim to “work in” immigration law without being an OAB-certified specialist.
• Having the official specialist title demonstrates verified expertise but isn’t required to practice in that area.
• Many excellent lawyers don’t have the specialist title because the exam is relatively new and voluntary.

How to verify specialist titles:

Ask the lawyer for their specialist title number and verify it with the OAB’s national council. Alternatively, search for them in the OAB’s specialist directory.

What about LL.M. degrees and other credentials?

An LL.M. (Master of Laws) is an academic degree, not an OAB specialist title. Both are valuable, but they’re different things. I hold an LL.M. from USC Gould — it demonstrates academic training but it’s separate from OAB specialization. Look for both practical experience and formal credentials.

Bonus: Verify the Law Firm Itself

If you’re considering a firm rather than a solo practitioner, verify the firm’s registration too:

• Sociedade de Advogados: A registered law firm partnership. You can verify registration with the OAB.
• Sociedade Individual de Advocacia: A single-lawyer firm entity. Also OAB-registered.
• CNPJ: Ask for the firm’s CNPJ (corporate tax ID) and verify it on the Receita Federal website.

A legitimate law firm in Brazil will be registered with both the OAB and the Receita Federal. If a “firm” has no CNPJ or no OAB registration as a sociedade, you may be dealing with an informal operation.

Frequently Asked Questions

Can a foreign lawyer practice in Brazil?

No — with very rare exceptions. To practice law in Brazil, you must have graduated from a Brazilian law school (or had a foreign degree revalidated by a Brazilian university), passed the OAB exam, and been admitted to the Brazilian Bar. I went through this entire process myself, which is why the “first American admitted to the OAB” distinction matters — it was genuinely difficult. Foreign lawyers can advise on their home country’s law but cannot represent clients in Brazilian legal matters.

What if my lawyer has a suspended status but says it’s a mistake?

It happens — administrative suspensions for unpaid dues can occur. But the burden of proof is on them. Ask them to resolve it with the OAB and provide updated proof of “Regular” status before you engage them. Don’t take their word for it.

How often should I re-verify my lawyer’s status?

For ongoing matters (litigation, long-term immigration cases), I’d suggest checking once every 6 months. It takes 30 seconds. Suspensions can happen mid-case, and you want to know immediately.

Are there lawyers who specialize in serving foreigners but aren’t registered?

Unfortunately, yes. Some immigration consultants and despachantes position themselves as “lawyers” to foreign clients. They may be helpful for document preparation, but they’re not lawyers and can’t represent you before courts, the Federal Police, or government agencies. See lawyer vs. immigration consultant for the critical differences.

What if the lawyer I’m considering doesn’t appear on ConfirmADV?

If they don’t appear at all, they’re either not registered or you may have misspelled their name. Try variations (Brazilian names can be registered differently than how the person uses them informally). If you still can’t find them, ask for their OAB number directly. If they won’t provide it or it doesn’t verify, do not hire them. Period.

My lawyer has two OAB numbers in different states. Is that normal?

Yes, completely normal. A lawyer registered in Sao Paulo (OAB/SP) who also practices in Rio de Janeiro will have a supplementary registration (OAB/RJ suplementar). Both should show as “Regular.”

“I encourage every potential client to check my OAB registration. Any lawyer who is offended by verification is revealing something about how they handle scrutiny — and that’s useful information.” — Zachariah Zagol, Founding Partner, OAB/SP 351.356

The Bottom Line

Verification isn’t about being paranoid — it’s about being smart. In a country with over 1.3 million registered lawyers and thousands of unregistered people offering “legal services,” five minutes on ConfirmADV is the highest-return due diligence you’ll ever do.
