General Business Use (Yes)

Whilst 100% legal; there are exceptions for very specific types of transactions. It is still up to the discretion of the independent user, or governing body, whether they are used or not. As each business needs are different and the agreements themselves may vary. We always advise you to speak with an authority within your businesses category.


Court-Admissible (Yes)

Each country has its own regulations that determine whether an electronic signature is seen as legal or not. So, as long as your electronic signature adheres to these, a signature won’t be rejected simply for not being handwritten.

e-Signature Legal Model (Tiered)

Brazil’s legal model is a tiered one. This means that Qualified Electronic Signatures are seen as a legal type of e-Signature. This doesn’t mean that a non-QES e-Signature can’t be submitted in court, but it will need extra evidence to support it.


eSignature Legality Summary

Under Brazilian law, a written signature is not necessarily required for a valid contract. Contracts are generally valid if legally competent parties reach an agreement, whether they agree verbally, electronically or in a physical paper document. According to the Brazilian Code of Civil Procedure, electronic records can be used to substantiate the validity of a contract.

The Provisional Measure No. 2,200-2/01, which created the “Infraestrutura de ChavesPúblicas Brasileira” (ICP Brasil), was established in 2001. e-Signatures used with the ICP-Brasil have authenticity, integrity, reliability and cannot be denied as evidence. The e-Signature stays linked to the signed electronic document. If the document undergoes any changes the e-Signature becomes invalid.

The eSignature Legality Guide is the result of legal research into the laws and practices regarding eSignature on a country-by-country basis. Each country-level analysis was conducted by local law firms located in that country, in that country’s local language. This legal analysis was then supplemented with complementary research on eSignature and digital signature technology standards conducted by independent technology experts. Together, this information is provided as a public resource to understand eSignature legality, and clarify some of the common misconceptions about international eSignature legality.


A basic measure of eSignature legality in a country is whether courts will admit eSignatures as evidence in court. In most countries in the world, an eSignature cannot be rejected simply because it is electronic, meaning that it should be admissible, subject to proof.

While there are exceptions for very specific types of transactions, eSignatures, independent of the underlying technology, may be used for the majority of general business transactions in most countries. Issues that may restrict general business use include local technology requirements or other restrictions on special transactions types. Learn more about specific transaction types, below.


‘Tiered’ countries recognize Qualified Electronic Signature (QES, or the locally named equivalent) as a distinct type of eSignature. In these countries, a QES has special legal status in the form of presumed authenticity, and may be legally required for a few, specific transaction types. In spite of this, a non-QES eSignature can still be submitted as evidence in court even in Tiered countries, so long as the party presenting it has sufficient evidence to prove that it is valid. Countries imposing QES standards often struggle to promote electronic business transactions, especially across country borders. ‘Open’ countries have no such technology requirements or eSignature types that receive special legal status.
