Buying a Company in Brazil: Legal Due Diligence Checklist (2026)

Reviewed by Luiz Eduardo da Silva, director of LegalBR. Updated on 25 October 2026. About 11 minutes to read.

Legal due diligence in Brazil is where foreign buyers find the liabilities that the seller’s presentation left out: tax assessments, labor claims, environmental duties that follow the land and gaps in the corporate records. Because several of these liabilities pass to the buyer by law, the checklist below decides both the price and the structure of the deal. It reflects the rules and antitrust thresholds in force in October 2026.

Why due diligence in Brazil works differently

In many jurisdictions, a buyer that acquires shares inherits the company’s history, while a buyer that acquires assets leaves most liabilities behind. Brazil narrows that distinction. Several statutes transfer liabilities to the acquirer of a business even in an asset deal, and courts tend to extend them in favor of employees, consumers and the tax authorities.

• Tax succession. Under the National Tax Code (CTN), articles 129 to 133, the company resulting from a merger or incorporation answers for the taxes of the absorbed companies. In addition, whoever acquires a business establishment and continues the activity may answer for the taxes owed up to the transfer.
• Labor succession. The CLT (articles 10, 448 and 448-A) protects employees when the ownership or structure of the business changes. The successor answers for labor debts, and the seller remains jointly liable in cases of fraud.
• Sale of a business (trespasse). When a business establishment is sold, the buyer answers for prior debts that were properly recorded in the books, and the seller stays jointly liable for one year (Civil Code, article 1,146).
• Anti-corruption. In mergers and incorporations, the successor answers for fines and full repair of damage under the Clean Company Act (Law 12,846/2013), up to the value of the assets transferred.

As a result, due diligence in Brazil is less about choosing a structure that avoids liabilities and more about measuring them precisely, then allocating them through price, escrow, indemnities and conditions precedent.

Certificates and searches

Brazil has a dense system of public certificates (certidões). They are fast, inexpensive and indispensable, but each one covers a narrow slice of risk. Therefore, the review should pull them for the target, for its branches and, where relevant, for its partners and administrators.

Certificates expire quickly, so the final set is usually pulled again close to signing and closing. A positive certificate with effects of negative (positiva com efeitos de negativa) means debts exist but are suspended, for example by an installment plan or a guarantee, and the underlying file still needs review. Our certificates and due diligence service organizes this collection across all states and courts.

Corporate and ownership review

The corporate review confirms that the seller can actually deliver what it is selling. In Brazil, it often uncovers gaps that do not appear in any certificate.

• Chain of title. Rebuild the history of the quotas or shares from incorporation to today. Each assignment of quotas in a limited company requires an amendment registered with the Board of Trade, and each transfer of shares in a corporation requires an entry in the share transfer book.
• Corporate books. A corporation (S.A.) keeps mandatory books, including the share register and minutes books. Missing, unsigned or outdated books are a common finding, and they can block a clean transfer of shares. See our corporate books service for how they are rebuilt.
• Liens and agreements. Check for pledges over quotas or shares, shareholder agreements, preemptive rights and transfer restrictions in the articles or bylaws.
• Foreign capital registration. If the target already has foreign shareholders, confirm that their investment is registered in the Central Bank’s SCE-IED system. An unregistered or outdated record complicates future dividend remittances and repatriation.
• Powers of the signatories. Confirm that the administrators who sign the deal have current powers and that all required approvals are in place.

Tax and labor review

Tax and labor are usually where the largest contingencies sit. The review goes well beyond certificates, because assessments under discussion, aggressive positions and payroll practices do not show up there.

Tax

• Map the tax regime (Lucro Real or Lucro Presumido) and test whether the company qualified for it. Our corporate tax guide explains the regimes.
• Review the last five years of returns, administrative and judicial tax disputes, installment programs and tax credits used to offset debts.
• Check state tax incentives (ICMS benefits), credits of PIS and COFINS, and the readiness for CBS and IBS, which are being phased in from 2026 to 2033.
• Assess transfer pricing on intercompany transactions, especially if the seller is a foreign group.

Labor and social security

• List pending labor claims and estimate their exposure by type of claim.
• Test the use of contractors hired as companies (pejotização), outsourcing arrangements, overtime controls and variable pay. These practices generate most labor liabilities in Brazil.
• Confirm eSocial reporting, FGTS deposits and health and safety programs required by the regulatory standards.

Environmental, real estate, regulatory and compliance

Environmental liability in Brazil is strict, which means it does not depend on fault (Law 6,938/1981). Moreover, the courts treat the duty to repair environmental damage as attached to the property, so the current owner can be required to remediate contamination caused by previous owners. For industrial sites, logistics yards and rural land, a technical environmental assessment should complement the legal review of licenses and permits.

• Real estate. Review the updated property record (matrícula) of every owned property. Since Law 13,097/2015, liens and lawsuits that affect a property should be recorded on its matrícula to be enforceable against a good faith buyer, which increases the weight of that document. Leases, zoning permits and fire department certificates also matter for operating sites.
• Rural land. Brazilian companies controlled by foreigners face limits and authorization requirements to acquire rural land (Law 5,709/1971). Targets with farmland, forestry or energy sites need a specific review.
• Regulatory licenses. Check sector licenses, such as health surveillance (ANVISA), energy (ANEEL), telecom (ANATEL) or financial services, and whether a change of control requires prior consent from the regulator.
• Data protection. Review compliance with the General Data Protection Law (LGPD), including records of processing, incidents and international data transfers.
• Integrity. Review dealings with public entities, compliance programs and investigations, given successor liability under the Clean Company Act.
• Contracts. Identify change of control clauses, exclusivity, guarantees given by the target and key customer and supplier dependencies.

Share deal or asset deal

The due diligence findings usually decide the structure. The table compares the two main routes as they work in Brazil.

In a quota deal involving a limited company, note that the seller remains jointly liable with the buyer for partner obligations for two years after the amendment is registered (Civil Code, article 1,003). In addition, when a non-resident seller makes a capital gain on Brazilian assets, the buyer or its attorney in Brazil is responsible for withholding the income tax due by the seller, so this point must be addressed in the purchase agreement.

Foreign buyers also need the practical pieces in place before closing: a CNPJ for the foreign acquiring entity, a resident legal representative and apostilled corporate documents. Our guide on CNPJ for foreign companies covers that registration.

CADE merger control

Brazil has a mandatory, suspensory merger control system under Law 12,529/2011. A transaction must be notified to the Administrative Council for Economic Defense (CADE) when, in addition to qualifying as a concentration, at least one group involved had gross revenue in Brazil of R$ 750 million or more in the year before the deal, and at least one other group had R$ 75 million or more. These values were set by an interministerial ordinance in 2012 and still apply in October 2026.

• No closing before approval. The parties must keep their businesses separate until CADE clears the deal. The law allows a review of up to 240 days, which may be extended to a maximum of 330 days. Simple cases follow a fast-track procedure and usually clear much sooner.
• Gun jumping. Closing early, or integrating operations before approval, can lead to fines from R$ 60 thousand to R$ 60 million, the nullity of acts and an investigation.
• Minority stakes. CADE rules also require notification of certain minority acquisitions without control, depending on the stake acquired and whether the target competes with or supplies the buyer.

Closing a deal after due diligence in Brazil

A due diligence report is useful only if its findings reach the contract. In practice, Brazilian purchase agreements translate findings into four tools.

1. Price adjustments for quantified liabilities and working capital differences.
2. Specific indemnities for known contingencies, usually with longer survival periods than general warranties, because tax and labor claims surface years later.
3. Escrow or holdback of part of the price, which is common in Brazil because enforcing an indemnity against a seller abroad or a dissolved seller is slow.
4. Conditions precedent such as CADE clearance, regulatory consents, regularization of corporate books and settlement of specific debts.

After closing, the registry work follows: the amendment or share register entry, updates to the CNPJ and its partner list, the Central Bank SCE-IED registration of the new foreign investment and the appointment of new administrators. Our guide on the SCE-IED registration explains that last step.
