Is an Electronic Signature Legally Valid in Brazil? (2026)

Yes. An electronic signature is legally valid in Brazil. Brazil is not part of the EU, so it does not use eIDAS. It has its own framework built around ICP-Brasil, the national public key infrastructure, and a law that sets out tiers of electronic signature for dealings with public bodies. For private contracts, parties are generally free to agree that an electronic signature binds them. This is general information, not legal advice. The rules and standards change, so confirm the current position before relying on any point below. ## The law that governs e-signatures in Brazil Two pieces matter most. The first is Provisional Measure 2.200-2 of 2001, which created ICP-Brasil, the Brazilian public key infrastructure. A digital signature backed by an ICP-Brasil certificate is presumed authentic and true in relation to the signatory. The same measure makes clear that other electronic signing methods are not excluded, as long as the parties accept them. The second is Law 14.063 of 2020, which sets out electronic signatures for interactions with public entities and defines a three-tier model. <!-- [VERIFY] the exact provisions of Provisional Measure 2.200-2/2001 and Law 14.063/2020 before citing specific articles --> For private contracts between businesses, the Civil Code and the principle of freedom of form mean most agreements can be made and signed electronically. ## The three types of signature Law 14.063/2020 defines three levels for use with public bodies, and the model is a useful guide generally. - Simple electronic signature (assinatura eletronica simples). Identifies the signatory and attaches or associates data. Suitable for lower risk interactions.

• Advanced electronic signature (assinatura eletronica avancada). Uses certificates not issued by ICP-Brasil but with features that link it uniquely to the signatory and detect later changes.
• Qualified electronic signature (assinatura eletronica qualificada). Uses an ICP-Brasil digital certificate. This is the highest tier and carries the strongest legal presumption. ## When you need a stronger signature For many private contracts a simple or advanced signature is accepted when the parties agree to it. An ICP-Brasil qualified signature is the safest choice where the law or a public body requires it, where you want the statutory presumption of authenticity, or where the value or sensitivity of the deal justifies strong proof of identity. Some filings and dealings with government require the qualified level. ## What you usually need extra care with Brazilian law allows electronic signatures broadly, but some acts still need a specific form, a notary, or registration, which an ordinary electronic signature does not by itself replace. These can include: - Acts that require a public deed (escritura publica), such as certain real estate transactions.
• Wills and some succession documents.
• Documents that a specific statute requires in a set form or requires to be registered. <!-- [VERIFY] the current list of Brazilian acts requiring a public deed, notarisation or registration before relying on it --> ## Making an electronic signature stand up in Brazil Even an accepted simple signature should be easy to prove. Good practice includes: - Recording identity, intent to sign, and consent to sign electronically, especially where the signature is not ICP-Brasil based.
• Keeping an audit trail of who signed, when, from where, and which version.
• Using an ICP-Brasil qualified certificate where the strongest presumption or a public body requires it.
• Storing the final signed file so later tampering would be detectable. The ICP-Brasil route gives the strongest legal footing; other methods work when the parties clearly accept them. ## Keeping signed contracts in one place An electronic signature is only the last step. Before it, a contract in Brazil has to be drafted, reviewed for risk, checked against local form and signing rules, and then tracked through its life so renewal dates and obligations are not missed. When that work sits in email, Word files and spreadsheets, the signed PDF often becomes the only record anyone can find later.

The point worth keeping is that signed contracts are easier to govern when the document, its signing evidence and its key dates stay together.
