E-Signature Legality in Brazil (2026): MP 2200-2 Compliance Guide

Key Takeaways: Medida Provisória 2.200-2: Legal Framework · Types of E-Signatures Recognized in Brazil · Key Requirements for Valid E-Signatures · Exceptions and Limitations

Brazil's electronic signature framework is governed by Medida Provisória 2.200-2/2001, which established the ICP-Brasil (Brazilian Public Key Infrastructure). In 2026, Brazilian e-signature law recognizes both certified (ICP-Brasil) and uncertified electronic signatures, with the latter gaining broader acceptance after Law 14.063/2020 introduced three signature tiers.

This guide covers everything businesses need to know about e-signatures in Brazil — from legal requirements to practical implementation.

Medida Provisória 2.200-2: Legal Framework

Brazil's e-signature ecosystem operates under a tiered system since Law 14.063/2020:

The ICP-Brasil system uses a hierarchical PKI structure with the ITI (Instituto Nacional de Tecnologia da Informação) as the root certificate authority. Qualified certificates can be obtained from authorized certificate authorities (ACs) throughout Brazil.

Types of E-Signatures Recognized in Brazil

Simple Electronic Signatures (SES)

• Any electronic method indicating intent to sign
• Valid for most private agreements between consenting parties
• Examples: typed name, click-to-sign, drawing on screen

Advanced Electronic Signatures (AES)

• Must be uniquely linked to the signatory
• Must identify the signatory with reasonable certainty
• Created using data under the signatory's sole control
• ZiaSign provides AES-compliant signatures for Brazilian businesses

Qualified Electronic Signatures (QES via ICP-Brasil)

• Created using a government-issued digital certificate
• Legally equivalent to a notarized handwritten signature
• Required for certain government interactions

Key Requirements for Valid E-Signatures

For an e-signature to be legally valid in Brazil:

1. Intent — Clear demonstration of the signer's intent to be bound
2. Identity — Adequate identification of the signatory (for AES/QES)
3. Integrity — The signed document must not be alterable after signing
4. Consent — All parties must agree to electronic transaction methods
5. Retention — Documents must be stored in accessible, reproducible format

Pro tip: For transactions with Brazilian government entities, ICP-Brasil certificates are generally required. For private B2B contracts, Advanced Electronic Signatures (like ZiaSign provides) are fully sufficient.

Exceptions and Limitations

E-signatures are not valid in Brazil for:

• Real estate transfers requiring public deed (escritura pública)
• Certain family law documents (marriage, adoption)
• Documents requiring notarization without remote online notarization
• Wills and testaments (must be handwritten or public deed)
• Some labor law documents (though this is rapidly changing with CLT updates)
