A European technology group agrees a letter of intent to acquire a São Paulo-based software company. The target looks clean on paper: audited accounts, no publicly listed disputes, and a capable management team. Six weeks into due diligence, the legal team uncovers undisclosed labour proceedings, a contested intellectual property licence, and a corporate structure that triggers mandatory approval from Brazil's competition authority. The deal does not collapse – but the timeline extends by four months, the price is renegotiated downward, and the acquirer's legal costs double. This scenario is not unusual. Brazil's legal system is sophisticated, multilayered, and unlike anything foreign acquirers encounter in common law jurisdictions.
M&A due diligence in Brazil is a structured legal review of the target company's corporate, tax, labour, regulatory, and contractual position before a share purchase agreement is signed. It must be completed before closing conditions are agreed and before representations and warranties are finalised. A thorough review typically takes between six and sixteen weeks, depending on the target's size and the quality of its records.
This guide sets out the step-by-step process, the documentary checklist, the most common errors made by foreign acquirers. The cost profile of a properly scoped review. Additionally, a decision framework for choosing the right approach in different transaction scenarios. Engaging a lawyer in Brazil with cross-border M&A experience is not optional at this stage – it is the primary control against post-closing liability.
Why Brazil requires a distinct due diligence approach
Brazil operates under a civil law system rooted in its civil and corporate legislation. The country's Consolidação das Leis do Trabalho (CLT – Brazil's consolidated employment legislation) creates an unusually broad set of employer obligations. These obligations generate contingent liabilities that do not always appear on a target's balance sheet. Foreign acquirers accustomed to common law due diligence frameworks routinely underestimate this exposure.
Tax is equally distinctive. Brazil's tax legislation is layered across federal, state, and municipal levels. A single commercial transaction may attract multiple levies simultaneously. Tax disputes in Brazil are among the most protracted of any major economy. An acquisition that absorbs a company with unresolved tax proceedings can bind the acquirer to those proceedings for years after closing.
Corporate legislation in Brazil regulates both sociedades anônimas (SAs – joint-stock companies) and sociedades limitadas (Ltdas – limited liability companies). The structural differences between these two forms affect how equity is transferred, how minority shareholders may challenge decisions, and what consents are needed before a share purchase can be completed. Identifying which form the target uses – and whether recent conversions have occurred – is a foundational step that must happen before any other review begins.
Regulatory oversight adds a further dimension. Brazil's competition authority, the Conselho Administrativo de Defesa Econômica (CADE), exercises mandatory pre-closing merger control over transactions that meet specified market thresholds. In addition, regulated sectors including financial services, insurance, telecommunications, and media require sector-specific approvals. These approvals are not formalities. Processing times at CADE can run from thirty days for simple cases to well over a year for complex ones. Failing to identify a mandatory filing before signing produces closing risk that cannot easily be unwound.

Step-by-step due diligence process in Brazil
The review unfolds across five sequential stages. Each stage produces outputs that feed directly into the share purchase agreement, the representations and warranties schedule, and the closing conditions checklist.
Stage 1 – Scope definition and document request (weeks 1–2). The process begins with a document request list sent to the target. This list covers corporate documents, material contracts, employment records, tax filings, regulatory licences, litigation registers, and intellectual property registrations. The quality of the target's response sets the pace of everything that follows. Targets with disorganised records – common in founder-led businesses – extend this stage significantly. Counsel should send an initial request and follow up within five business days. Gaps in the initial response are themselves a finding.
Stage 2 – Corporate and title review (weeks 2–4). Counsel examines the target's corporate books, shareholder agreements, and the chain of title for the shares being acquired. In Brazil, share registers must be physically maintained under corporate legislation. Discrepancies between the register and the stated cap table are not rare, particularly in companies that have undergone informal share transfers. Any encumbrances – pledges, usufructs, or tag-along rights held by departing shareholders – must be identified and mapped against the SPA structure.
Stage 3 – Tax, labour, and regulatory review (weeks 3–8). This is the most time-intensive stage. Tax review covers all federal, state, and municipal obligations, including any pending administrative proceedings before the Conselho Administrativo de Recursos Fiscais (CARF – Brazil's federal tax appeals body). Labour review covers the CLT obligations, active proceedings before the Tribunal Superior do Trabalho (TST. Brazil's Superior Labour Court). Trade union agreements. Additionally, whether the target has used third-party service providers in ways that could give rise to joint employer liability. Regulatory review confirms all licences in force, identifies any breach notifications, and maps the CADE merger control analysis.
Stage 4 – Contracts and IP review (weeks 4–7). Material contracts are reviewed for change-of-control clauses. In Brazil, many commercial agreements contain provisions that automatically terminate or grant counterparty consent rights upon a change of ownership. Failing to identify these before signing can result in the acquirer inheriting a business whose key contracts have lapsed. Intellectual property review covers registrations with the Instituto Nacional da Propriedade Industrial (INPI – Brazil's industrial property office), licence chains, and any open disputes over ownership.
Stage 5 – Report, SPA input, and closing conditions (weeks 8–12). Counsel consolidates findings into a due diligence report structured by risk category. Each identified risk is assessed for materiality and mapped to one of three responses: a specific indemnity in the SPA, a price adjustment, or a pre-closing remediation condition. Closing conditions are drafted to include CADE clearance where required, sector approvals, and any corporate consents identified in Stage 2. The representations and warranties schedule is drafted against the findings of this report.
Documentary checklist: what foreign acquirers must request
The following categories represent the core of a Brazil-specific document request. Each category carries distinct risks that counsel should assess independently.
Corporate records. Request the target's current and historical articles of association. All amendments to the corporate contract or estatuto social (corporate bylaws), minutes of shareholder meetings and board meetings for at least five years, and the share register. For SAs, request the full register of nominative shares. For Ltdas, confirm that all quota transfers have been properly registered.
Tax records. Request federal tax clearance certificates (certidões negativas de débitos), state and municipal equivalents, payroll tax records, transfer pricing documentation, and any correspondence with the Receita Federal (Brazil's federal tax authority). Active disputes at CARF should be individually assessed for provisioning adequacy.
Labour and employment records. Request a complete list of employees and their employment terms, all trade union (sindicato) agreements, records of third-party service contracts, and a register of active and resolved labour proceedings. Brazil's employment legislation creates strict rules on overtime, profit-sharing, and termination – all of which generate quantifiable contingent liability.
Regulatory licences. Request all operating licences, environmental permits, sector-specific regulatory approvals, and any correspondence with regulatory bodies indicating breach or enforcement risk. For businesses in regulated sectors, confirm whether licences are transferable upon a change of control.
Material contracts. Request all contracts above a defined threshold value, all long-term supply or distribution agreements, and any agreements with public entities. Confirm whether any contract contains change-of-control provisions or exclusivity clauses that affect post-closing operations.
Intellectual property. Request INPI registration certificates for all trademarks, patents, and software registrations. Confirm ownership – many Brazilian technology companies hold IP in the name of founders rather than the operating entity. Confirm that all employee invention rights have been properly assigned under employment legislation.
Common errors by foreign acquirers – and how to avoid them
The most consistent error is relying on the target's own representations as a substitute for independent legal review. In Brazil, the legal maxim caveat emptor (buyer beware) applies in full. Courts have consistently held that a purchaser who fails to conduct adequate due diligence bears the consequence of undiscovered liabilities, subject to the specific terms of the SPA's indemnification provisions.
A second frequent error is underweighting labour risk. Foreign acquirers from common law systems often expect financial audits to capture employment liabilities. They do not – not reliably. Brazil's employment legislation generates claims that surface months or years after an employment relationship ends. A proper legal review requires analysis of actual employment relationships, not just payroll records.
A third error is assuming that a clean tax clearance certificate means no tax risk. Clearance certificates confirm the absence of registered debts at the date of issue. They do not address potential reclassification of past transactions or the outcome of pending audits that have not yet produced an assessment. Counsel should review tax audit history and the target's positions on disputed items independently.
Timing errors are also common. Foreign acquirers sometimes compress the due diligence timeline to match the seller's preferred schedule. In Brazil, this creates disproportionate risk. CADE filings, if required, must be made after signing and before closing. If the transaction requires a mandatory CADE notification and this is not identified until after the SPA is executed. The parties face the prospect of a binding agreement that cannot be completed lawfully without regulatory approval they did not plan for.
Finally, many international buyers underestimate the importance of coordinating Brazilian counsel with their home-jurisdiction legal team. The SPA for a cross-border acquisition may be governed by English law or New York law – but the representations and warranties it contains must reflect Brazilian legal reality. A misalignment between the governing law of the SPA and the legal regime that generates the underlying risk is a structural vulnerability that skilled counsel on both sides must address directly.

Cost profile and decision framework
Legal fees for a Brazil due diligence review vary with transaction size, target complexity, and the number of workstreams engaged simultaneously. For a focused review of a single operating entity with straightforward corporate and tax records, fees typically fall in the range of tens of thousands of US dollars. Multi-entity targets, regulated sector acquisitions, or targets with significant litigation histories will require broader scopes – and correspondingly higher fees.
The relevant comparison is not between the cost of due diligence and the cost of proceeding without it. The relevant comparison is between the cost of a thorough review and the cost of a post-closing dispute over undisclosed liabilities. Brazilian courts are competent and relatively efficient by regional standards, but commercial litigation timelines are measured in years, not months. A well-scoped due diligence process is the principal instrument for avoiding that outcome.
The decision framework depends on three variables: transaction size, the target's sector, and the acquirer's tolerance for post-closing risk. Small acquisitions in low-regulation sectors with a target that has clean records may support a condensed review of four to six weeks, focused on title, material contracts, and basic tax clearance. Mid-sized acquisitions in any sector warrant the full five-stage process described above. Acquisitions in regulated sectors – regardless of size – require the full process plus dedicated regulatory counsel. Acquisitions where the acquirer will use the target's existing contracts as a revenue base require particular attention to change-of-control provisions in Stage 4.
Where the acquirer intends to acquire assets rather than shares, a different but equally detailed review applies. Asset acquisitions in Brazil carry their own risks under commercial and employment legislation, including potential successor liability for pre-existing labour claims. The choice between a share deal and an asset deal should be made with full knowledge of the liability profile identified in due diligence – not before it.

Self-assessment checklist before engaging in Brazil due diligence
This process is most directly applicable where:
- The acquirer is a foreign entity purchasing shares or a controlling interest in a Brazilian company
- The target is incorporated in Brazil as an SA or Ltda
- The transaction involves assets, contracts, or employees located in Brazil
- The combined market position of the parties may trigger CADE merger control thresholds
- The acquirer intends to rely on the target's existing revenue contracts post-closing
Before initiating the review, verify the following:
- A data room has been established and access has been granted to Brazilian legal counsel
- The target has confirmed the structure of its corporate group and identified all subsidiaries
- A preliminary CADE threshold analysis has been completed by local counsel
- The governing law and dispute resolution mechanism for the SPA have been agreed in principle
- The acquirer's home-jurisdiction counsel and Brazilian counsel have been introduced and aligned on scope
If any of the above conditions are not yet met, the document request should not be sent. Sending a request before the data room is properly configured, or before counsel alignment is confirmed, produces a fragmented review with gaps that are difficult to close before signing.
Frequently asked questions
Q: How long does M&A due diligence in Brazil typically take?
A: A focused due diligence review of a mid-sized Brazilian company typically takes between six and twelve weeks. Larger targets or businesses with complex regulatory histories may require sixteen weeks or more. The timeline depends heavily on the quality and organisation of the target's document room.
Q: Do foreign acquirers need Brazilian regulatory approval to complete an acquisition?
A: Many transactions require prior approval from CADE, Brazil's competition authority, where combined market thresholds are met. Certain regulated sectors – including financial services, insurance, and media – also require approval from sector-specific agencies. These approvals are closing conditions that must be satisfied before the share purchase agreement can be completed.
Q: Is it a misconception that Brazilian labour liabilities are always disclosed in financial statements?
A: Yes. A common misconception among foreign acquirers is that financial audits capture the full scope of labour exposure. Brazilian employment legislation creates contingent liabilities that are frequently not provisioned on the balance sheet. Independent legal due diligence of employment records, trade union agreements, and active labour proceedings is essential before signing.
