Is an electronic signature legal in Brazil?
Is an e-signature legal in Brazil?
Yes, for most contracts, under MP 2.200-2/2001 and Lei 14.063/2020. Medida Provisória 2.200-2/2001 gives ICP-Brasil certificate signatures a presumption of authenticity and expressly allows other means of proving authorship and integrity when the parties accept them, so simple e-signatures are widely used for private contracts.
Main exceptions: Transfer and registration of real estate: qualified (ICP-Brasil) signature required (Lei 14.063/2020, art. 5 §2 IV); Acts signed by heads of branches of government and ministers: qualified signature required; Most electronic invoices (notas fiscais eletrônicas): qualified signature required, optional for individuals and MEIs.
Our take: Brazil is one of the friendliest countries for simple e-signatures between private parties, as long as you do one thing: write into the contract that both sides accept electronic signing and the method used. That clause engages MP 2.200-2 Article 10 §2 directly. Where Brazil gets strict is with public bodies, real estate and electronic invoices, which need ICP-Brasil qualified signatures. eSignSimple provides simple electronic signatures with an audit trail, so it fits service agreements, NDAs and freelance contracts, not a property transfer or a nota fiscal.
Which laws govern electronic signatures in Brazil?
Medida Provisória nº 2.200-2, de 24 de agosto de 2001
Created the ICP-Brasil public key infrastructure. Article 10 §1 presumes documents signed with ICP-Brasil certificates to be true in relation to the signatories, and §2 states that the MP does not prevent the use of other means of proving authorship and integrity, including non-ICP-Brasil certificates, if the parties accept them as valid or the person the document is used against accepts it.
Lei nº 14.063, de 23 de setembro de 2020
Classifies electronic signatures into simple, advanced and qualified (Article 4) and sets the minimum level required in interactions with public bodies (Article 5).
What are Brazil's three levels of electronic signature?
Simple: identifies the signatory and attaches or associates data with other electronic data of the signatory. Advanced: uses non-ICP-Brasil certificates or another means of proving authorship and integrity accepted by the parties, is uniquely linked to the signer, under their exclusive control, and makes later changes detectable. Qualified: uses an ICP-Brasil digital certificate and has the highest level of trust.
Can private contracts use simple e-signatures in Brazil?
Between private parties, MP 2.200-2 Article 10 §2 is the key rule: any means of proving authorship and integrity is valid if the parties accept it. That is why simple and advanced signatures are common for commercial contracts, NDAs, service agreements and employment documents.
Qualified ICP-Brasil signatures enjoy a legal presumption of truth in relation to the signers, which reduces the burden of proof in a dispute.
What applies to public bodies and real estate in Brazil?
Lei 14.063/2020 lets each public body set the minimum level it accepts. Simple signatures can be admitted for low-impact interactions, advanced signatures for others (including registrations at the Juntas Comerciais), and qualified signatures are accepted in any interaction.
Article 5 §2 makes a qualified signature mandatory for, among others, acts of transfer and registration of real estate (subject to the Juntas Comerciais exception) and the issuance of most electronic invoices (notas fiscais eletrônicas).
How should you e-sign contracts in Brazil?
Put a clause in your contract where the parties agree to sign electronically and accept the chosen method, which directly engages MP 2.200-2 Article 10 §2.
eSignSimple provides simple electronic signatures with an audit trail that records timestamps, IP addresses and a document hash. It does not issue qualified, advanced or certificate-based signatures, so where a law requires one of those you will need a licensed or accredited provider.

- Acts signed by heads of branches of government and ministers: qualified signature required
- Most electronic invoices (notas fiscais eletrônicas): qualified signature required, optional for individuals and MEIs

Frequently asked questions
Does eSignSimple meet the requirements in Brazil?
For private contracts where the parties accept the method, yes: MP 2.200-2 Article 10 §2 allows it, and eSignSimple adds an audit trail and SHA-256 fingerprint. It does not issue ICP-Brasil qualified signatures, so it is not suitable for real estate registration, most notas fiscais or public bodies requiring qualified signatures.
Do I need an ICP-Brasil certificate to sign a contract?
Not for most private contracts. MP 2.200-2 allows other methods if the parties accept them. ICP-Brasil signatures carry a presumption of authenticity, which helps in disputes.
What is the difference between advanced and qualified signatures in Brazil?
Advanced signatures use non-ICP-Brasil certificates or other accepted means with specific security features. Qualified signatures use an ICP-Brasil digital certificate.
Can real estate transfers be e-signed?
Acts of transfer and registration of real estate require a qualified electronic signature under Lei 14.063/2020.
