# Verify Brazilian Lawyer: OAB Number Check in 2 Minutes **URL:** **Lang:** pt-BR --- [Expat Legal Guide](https://www.ribeirocavalcante.com.br/english/expat-legal-guide/) 18 min read By: [Lucas Ribeiro Cavalcante](https://www.ribeirocavalcante.com.br/autor/lucas/) | OAB/CE 44.673 # Verify Brazilian Lawyer: OAB Number Check in 2 Minutes Published: 24/08/2026 | Last updated: 09/09/2026 Content reviewed by Lucas Ribeiro Cavalcante, attorney — OAB/CE 44.673, on 09/09/2026 Facebook WhatsApp Share **Quick Summary** Only registration with the Ordem dos Advogados do Brasil (OAB) allows someone to legally advise or represent you in Brazil. You can check any lawyer's name or OAB number free on the OAB national database in under two minutes. Under Law 8.906/1994, legal acts performed by unregistered persons are null and your money is usually unrecoverable. You are about to hand a stranger in Brazil control over your money, your visa, or your property. That fear is rational, and it has a two-minute solution. Almost every horror story we hear from foreigners in Brazil starts the same way: a friendly, fluent, confident “lawyer” who was never a lawyer at all. In Brazil there is exactly one credential that decides whether a person can legally advise you, sign a petition for you, or represent you before a court: registration with the **Ordem dos Advogados do Brasil (OAB)**, the Brazilian Bar Association. Not a diploma. Not a business card. Not a website with a photo of the Rio skyline. Under Law 8.906/1994, the Bar Statute, acts reserved to lawyers that are performed by someone who is not registered with the OAB are **null**. Null means they never legally happened. Checking this costs R$ 0.00 and takes less than two minutes on the OAB’s national database. Yet thousands of foreigners skip it every year, pay five figures in reais, and only discover the problem when a deadline is lost or a contract is challenged. This guide explains why that happens so often, how to verify credentials yourself, what each registration status actually means, and what to do if the name does not come up. On this page ## What Is the Costliest Mistake Foreigners Make When Hiring a Lawyer in Brazil? The costliest mistake is paying a large sum to someone who is not registered with the OAB. Under Article 4 of Law 8.906/1994, acts exclusive to lawyers performed by an unregistered person are legally null. That means a petition, a legal opinion, or a representation agreement can be treated as if it never existed, and the money is usually gone. Start from the worst case and the rule becomes obvious. Imagine you pay R$ 80,000 to a “lawyer” to handle a beachfront apartment purchase in Bahia. He drafts the purchase agreement, holds your funds, and arranges the transfer at the cartório (notary office). Months later a family member of the seller challenges the sale. Your representative was never registered with the OAB, so the legal advisory work he performed is null, the power of attorney he used may be defective, and he has no professional insurance, no OAB disciplinary record, and no assets in his name. **Common mistake:** assuming that because the money went through a bank transfer and there were signed papers, the transaction is protected. In Brazil, formality is everything. A signed document produced by someone legally incapable of producing it is not a shield, it is evidence that you were misled. The same logic destroys immigration cases. A residency application prepared by an unlicensed “consultant” who then disappears leaves you with no one who can legally answer a formal request for clarification from the Polícia Federal (Federal Police). Deadlines in Brazilian administrative processes are short and unforgiving, and the authority will not reopen a case because your representative was a fraud. ## What Is the OAB and Why Is It the Only Credential That Counts? The OAB is Brazil’s single national bar association, created by Law 8.906/1994, with a state chapter (Conselho Seccional) in each of the 26 states plus the Federal District. Every practising lawyer holds an inscrição (registration) with a number formatted as state plus digits, for example OAB/SP 351.356 or OAB/CE 44.673. Without it, there is no lawyer. Brazil follows the Civil Law tradition, not Common Law. There is no split between solicitors and barristers, no separate licensing board per state as in the United States, and no parallel regulator. One law school degree plus one national bar exam (Exame de Ordem) plus one registration equals one profession. That simplicity is good news for you: there is a single list to check. The Bar Statute reserves two activities to registered lawyers. First, representing clients before courts. Second, and this is the part foreigners rarely know, **legal consultancy, advisory work and legal opinions**. “Legal advice” is not an open market in Brazil. When an unlicensed immigration consultant tells you which visa category fits your situation and what the legal consequences are, that is regulated activity performed illegally. **Worth knowing:** the Statute also provides escalating disciplinary penalties for registered lawyers who breach professional duties, ranging from censure to suspension to exclusion from the Bar. This matters to you because a suspended lawyer is temporarily *prohibited* from practising, and acts performed during suspension are just as null as acts performed by someone who was never registered. You can read the full text of the Bar Statute on the Brazilian government’s legislation portal, [Law 8.906/1994 on planalto.gov.br](https://www.planalto.gov.br/ccivil_03/leis/l8906.htm). It is in Portuguese, but Articles 1, 3 and 4 are short and worth running through a translator if you want to see the rule with your own eyes. ## How Do You Verify a Brazilian Lawyer’s OAB Registration in Under Two Minutes? Use the Cadastro Nacional dos Advogados (National Register of Lawyers), the OAB’s official free database at [cna.oab.org.br](https://cna.oab.org.br/). Search by full name, by registration number, or by CPF. The cost is R$ 0.00, no account is needed, and results appear instantly with the lawyer’s photo, state chapter, registration number and current status. Here is the sequence that catches almost every problem: - **Ask for the OAB number in writing.** A legitimate Brazilian lawyer gives it without hesitation, usually in their email signature. Format: OAB/[state] [number]. - **Ask for the full name as registered.** Many Brazilians use a shortened professional name. You want the name on the registration. - **Search the CNA by number first, then by name.** Searching by number tells you who that number actually belongs to. This detects the classic fraud of borrowing a real lawyer’s number. - **Compare the photo.** The CNA shows the registered photo. If the person you are meeting on video does not match, stop there. - **Check the “situação” (status) field.** Only “Regular” or “Ativo” means the person can practise today. - **Check the state chapter.** A lawyer registered in one state can act nationwide, but a firm claiming a São Paulo office with a lawyer registered only in Acre deserves a follow-up question. **In practice:** a client of ours in Lisbon was quoted €4,500 by an “immigration lawyer in Brazil” for a family reunion residency. The name returned no result on the CNA. The number he had provided belonged to a real labour lawyer in Minas Gerais who had never heard of him. Two minutes of searching prevented a five-figure loss in reais. If you want the click-by-click version with screenshots of the portal, we published a dedicated walkthrough on how to [verify a Brazilian lawyer’s OAB registration free online](https://www.ribeirocavalcante.com.br/brazil-expat-guide/verify-oab-registration/). ## What Do the OAB Status Labels Actually Mean for Your Case? Only an active registration allows legal practice. Under Article 4 of the Bar Statute, acts reserved to lawyers are null when performed by someone unregistered, suspended, on leave (licenciado), barred (impedido), or whose registration was cancelled. A “found” result on the CNA is not enough by itself. The status line is what protects you. | Status on the CNA | Portuguese term | Can this person legally act for you? | | --- | --- | --- | | Active / regular | Ativo / Regular | Yes. Full practice rights nationwide. | | Suspended | Suspenso | No. Disciplinary penalty. Acts performed are null. | | On leave | Licenciado | No. Voluntarily inactive (illness, public office, personal reasons). | | Barred / conflicted | Impedido | Partially. Cannot act in matters involving certain public bodies. | | Cancelled | Cancelado | No. Registration terminated. Acts are null. | | Law student trainee | Estagiário | Only limited acts, always supervised by a registered lawyer. | | Not found | Não encontrado | Treat as not a lawyer until proven otherwise. | **Heads up:** a “não encontrado” result is not always fraud. Recently admitted lawyers can take a few weeks to appear in the national database, and spelling variations in Brazilian surnames (Cavalcante versus Cavalcanti, Souza versus Sousa) produce false negatives constantly. Search by registration number and by CPF before drawing conclusions. The Estagiário category is the one foreigners misread most often. A law student registered as a trainee is a real entry in the database, which makes the profile look legitimate. But a trainee cannot give you independent legal advice or sign your petitions alone. If a trainee is your only point of contact and no supervising lawyer is named in the engagement letter, that is a structural problem, not a detail. ## Do You Even Need a Lawyer in Brazil? The Strongest Argument Against Hiring One Here is the honest counter-argument, in its strongest form. Most Brazilian immigration and tax procedures do not legally require a lawyer. The Federal Police charges a fixed fee of R$ 204.77 for CRNM registration (roughly US$ 40), the forms are online, and a competent despachante or consultant who has done it 300 times may genuinely be faster and cheaper than a law firm. That argument is correct as far as it goes, and any lawyer who denies it is selling you something. Registering a CPF, scheduling a Federal Police appointment through the [Polícia Federal portal on gov.br](https://www.gov.br/pf/pt-br), or submitting an ordinary residency renewal are administrative acts. You can do them yourself. Many people should. Now the answer. The distinction is not “simple versus complicated”, it is **form-filling versus legal judgment**. The moment someone tells you which residency category your situation fits, how a foreign document will be interpreted, whether your marriage certificate needs apostille and sworn translation, what happens to your tax residency, or how to respond to a denial, that is legal advisory work reserved by law to registered lawyers. When a non-lawyer does it, three protections vanish at once: - **No accountability.** A registered lawyer answers to the OAB disciplinary system and can be censured, suspended or excluded. A consultant answers to nobody. - **No privilege.** Lawyer-client confidentiality in Brazil is a professional duty tied to OAB registration. Your consultant’s WhatsApp history is not protected. - **No standing.** If the case becomes contentious and goes to court, your consultant cannot file anything. You start over, often after the deadline has passed. So the practical rule is: use official channels and your own hands for pure paperwork, and use a verified OAB-registered lawyer the moment a decision, a risk assessment, or money at stake enters the picture. Our overview of [real Brazilian bureaucracy timelines for foreigners](https://www.ribeirocavalcante.com.br/brazilian-bureaucracy-timelines-foreigners-2026/) shows which processes genuinely justify professional help and which do not. ## Why Do So Many Foreigners Lose This Protection Without Realising It? Because the warning signs are cultural, not legal, and foreigners cannot read them. A Brazilian client instinctively expects an OAB number on a business card and a written fee agreement. A newcomer sees a bilingual website, a WhatsApp reply in 20 minutes, and assumes competence. The gap between those two expectations is exactly where fraud operates. These are the patterns we see repeatedly in cases that reach us after the damage is done: - **No OAB number anywhere.** Brazilian professional ethics rules require lawyers to identify themselves by registration number in professional communications. Absence is not modesty, it is a signal. - **Titles that sound legal but are not.** “Legal consultant”, “immigration specialist”, “documentation agent”, “paralegal”. None of these is a regulated title in Brazil. - **Payment to a personal account with no invoice.** Fees should be paid against a written contract (contrato de honorários) and a proper receipt or nota fiscal. - **Guaranteed outcomes.** “Approval guaranteed in 30 days” is a promise no lawyer is allowed to make, because no lawyer controls the Federal Police or a judge. - **Pressure to sign a broad power of attorney fast.** A procuração should describe specific powers. A blank cheque over your assets is not normal. - **Refusal to put anything in writing in English.** Legitimate firms serving foreigners explain the scope, the fee and the timeline in a language you understand. **Worth knowing:** practising a regulated profession without qualification is itself unlawful in Brazil, and the OAB actively prosecutes it through its Comissão de Fiscalização. Reporting a fake lawyer is not just revenge, it is often the fastest way to build the paper trail you will need to recover money. ## What Changed in 2026 for Verifying Brazilian Lawyers? The legal rule has not changed: Law 8.906/1994 still governs, and OAB registration is still mandatory. What changed is the verification environment. The CNA database remains free at R$ 0.00, digital OAB credentials with QR codes are now standard, and courts have moved almost entirely to electronic filing, which makes an invalid representation surface faster than it used to. Three practical developments matter to you in 2026: - **Digital ID with QR code.** Brazilian lawyers carry a digital OAB credential in the OAB app. You can ask for a screenshot and scan the code, which resolves to the official OAB record rather than to a file the person controls. - **Electronic case files everywhere.** Filing in Brazil now requires a personal digital certificate tied to the lawyer’s registration. A non-lawyer physically cannot file for you. That is protective, but it also means the fraud shifts to the pre-litigation phase: fake “advice”, fake negotiations, fake fee collection. - **AI-generated legal content.** Convincing bilingual websites and “law firm” profiles can now be produced in an afternoon. Design quality has stopped being any indicator of legitimacy. The database is. **Heads up:** the OAB awards an official Título de Especialista (specialist title) in fields such as Direito Imigratório (Immigration Law), Direito Imobiliário (Real Estate Law), Direito Tributário (Tax Law) and Direito Internacional (International Law). Many excellent lawyers do not hold it, so its absence proves nothing. But a firm claiming an official specialisation that does not appear on the OAB record is misrepresenting itself. ## Step-by-Step: How to Hire a Brazilian Lawyer Safely Follow six steps, in this order, before you transfer any money. The verification stage costs nothing and takes minutes. The documentation stage is where most disputes are actually prevented: a written fee agreement naming the lawyer’s OAB registration number is your single best piece of evidence if anything goes wrong. - **Step 1. Collect the data.** Full registered name, OAB state and number, CPF or the firm’s CNPJ, and the office address. - **Step 2. Search the CNA.** Go to cna.oab.org.br, search by number, then by name. Confirm status is active and the photo matches. - **Step 3. Cross-check the firm.** Law firms in Brazil are registered as a sociedade de advogados with the OAB and have a CNPJ. Ask for both. A firm with no CNPJ and no OAB society registration is an individual practice wearing a firm’s clothes. - **Step 4. Demand a written engagement.** The contrato de honorários should state the scope of work, the total fee, the payment schedule, what is excluded (court costs, cartório fees, translations), and the lawyer’s OAB number. Ask for a bilingual version. - **Step 5. Read the power of attorney.** The procuração should list specific powers. Powers to receive money, sell property or settle claims on your behalf should be granted only when strictly necessary and clearly explained. - **Step 6. Pay traceably.** Bank transfer to the firm’s account (CNPJ) or to the lawyer’s account named in the contract. Keep every receipt for at least five years. **In practice:** for a straightforward residency filing, a bilingual Brazilian firm typically quotes between R$ 3,000 and R$ 8,000 in professional fees, separate from the government charge of R$ 204.77 collected by the Federal Police. A quote of R$ 25,000 for the same procedure, from someone who will not give you an OAB number, is a red flag by price alone. Our breakdown of typical [English speaking lawyer fees in Brazil for 2026](https://www.ribeirocavalcante.com.br/english-speaking-lawyer-brazil-2026/) gives you a benchmark before you negotiate. One document trap deserves a line of its own. Foreign documents used in Brazilian legal processes almost always need an apostille and a sworn translation by a tradutor público. An unlicensed consultant who never mentions this is not saving you steps, they are setting your case up to be rejected. Check our [apostille document checklist for Brazil](https://www.ribeirocavalcante.com.br/apostille-for-brazil-document-checklist-2026/) before you submit anything. ## Frequently Asked Questions About OAB Registration and Verification These are the questions foreigners search most often when checking a Brazilian lawyer. Short answers first: verification is free, it works from abroad, and a foreign lawyer cannot practise Brazilian law without OAB registration. ### Can I verify a Brazilian lawyer from outside Brazil? Yes. The Cadastro Nacional dos Advogados at cna.oab.org.br is open worldwide, free, and requires no Brazilian document or account. You can search by name, by OAB registration number or by CPF from anywhere. The interface is in Portuguese, but the fields you need are simple: “Nome” (name), “Inscrição” (registration number), “Seccional” (state chapter) and “Situação” (status). Browser translation handles the rest. If a result does not appear, try the registration number alone and check surname spelling variants before concluding anything. ### Can a foreign lawyer practise law in Brazil? Not as a Brazilian lawyer. Under Law 8.906/1994, only OAB-registered professionals may represent clients before Brazilian courts or provide Brazilian legal advice. Foreign lawyers may register with the OAB as a consultor em direito estrangeiro (foreign law consultant), which allows them to advise on the law of their own jurisdiction, not on Brazilian law. In practice, cross-border matters work best as a team: your home-country lawyer plus a verified Brazilian lawyer. Beware of anyone marketing themselves as an “international lawyer” handling Brazilian filings without an OAB number. ### What happens if my lawyer’s registration was suspended mid-case? Acts performed during a suspension are null under the Bar Statute, so anything filed in that window can be challenged. Practically, you must appoint a new lawyer immediately and have them review everything filed, then request whatever remedy is available for acts already lost. This is why verification is not a one-time event. If your case runs for a year, re-check the CNA every few months. It costs nothing, and a suspended lawyer has no obligation to volunteer the news to you. ### Can I get my money back from a fake lawyer? Sometimes, and your paper trail decides it. Recovery normally runs on two tracks: a civil claim for restitution and damages, and a criminal complaint (fraud, plus illegal practice of a regulated profession). Traceable bank transfers, a written agreement, and preserved WhatsApp messages make the civil case realistic. Cash payments with no contract make it very hard. File a complaint with the relevant OAB state chapter as well, because the Bar’s oversight commission investigates people falsely claiming to be lawyers and its findings support your case. ### Is a despachante the same thing as a lawyer? No. A despachante is a document facilitator, useful and legitimate for queues, filings and vehicle or registry paperwork. What a despachante may not do is give legal advice, interpret your rights, or represent you in a contentious matter. Many foreigners use a despachante for a CPF or an apostille errand and a lawyer for anything involving risk. That combination is perfectly sensible. The problem starts when a despachante is presented to you as a “lawyer” and charges lawyer-level fees. ### Do I need a CPF before hiring a Brazilian lawyer? No, you can sign an engagement letter and grant a power of attorney without a CPF, and a lawyer can help you obtain one. But almost everything else in Brazil, from opening a bank account to registering property, requires a CPF, so it is usually the first step your lawyer will take. If you want to know exactly where the wall is, see our guide on [what you can and cannot do without a CPF in Brazil](https://www.ribeirocavalcante.com.br/without-a-cpf-in-brazil-2026/). ## OAB Verification at a Glance | Item | Detail | | --- | --- | | Official database | Cadastro Nacional dos Advogados (CNA), cna.oab.org.br | | Cost to verify | R$ 0.00 | | Time needed | Under 2 minutes | | Search fields | Name, OAB registration number, CPF, state chapter | | Governing law | Law 8.906/1994 (Bar Statute), Articles 1, 3 and 4 | | Consequence of unregistered practice | Reserved acts are null; possible criminal and civil liability | | Only acceptable status | Active / regular | | Federal Police CRNM fee (2026) | R$ 204.77, paid to the government, never to a consultant as “the fee” | | Typical bilingual firm fee, residency filing | R$ 3,000 to R$ 8,000, in writing, before payment | | Re-verify | Every few months on long-running cases | ## Verify Your Brazilian Lawyer’s OAB Registration Before You Pay Anything Navigating Brazilian law from abroad is hard enough without wondering whether the person answering your messages is real. You should not have to take that on faith, and now you do not have to. One free database, one status field, and one written contract naming an OAB number is the whole defence. Our team is fully registered with the OAB and works in English, Portuguese and Spanish on immigration, real estate, contracts and litigation for foreign clients.
