Electronic signatures in BrazilBuilt for business
across Brazil.

For the documents Provisional Measure 2.200-2 of 24 August 2001 deals with, article 10 says those electronic documents are public or private documents for all legal purposes. Paragraph 1 says statements in documents produced with the ICP-Brasil certification process are presumed true as to the signatories, in the form of article 131 of Law 3,071 of 1 January 1916. The text on the Planalto site still cites that 1916 article. Paragraph 2 says the measure does not prevent another means of proving authorship and integrity of an electronic document, including certificates not issued by ICP-Brasil, if the parties admit that means as valid or the person against whom the document is used accepts it. Article 107 of the Civil Code, Law 10,406 of 2002, says a declaration of will needs no special form unless the law expressly requires one. Article 219 says statements in signed documents are presumed true as to the signatories. Article 221 says a private instrument signed by a person who can freely dispose of their property proves conventional obligations of any value, but its effects against third persons do not arise before it is filed in a public registry. The standard inSigner signature is a simple electronic signature. It is not an advanced electronic signature under article 4, item II, of Law 14,063 of 2020, and it is not an ICP-Brasil qualified signature. Whether paragraph 2 applies still depends on the document, the parties, and the person the document is used against. inSigner does not decide that question.

Law 14,063 of 23 September 2020 classifies electronic signatures in article 4. A simple electronic signature identifies the signer and attaches or associates data with other electronic data of the signer. An advanced electronic signature uses a certificate not issued by ICP-Brasil, or another means of proving authorship and integrity, if the parties admit it as valid or the person against whom the document is used accepts it. It must also be linked to the signer in a univocal way, use creation data the signer can operate under exclusive control with a high level of confidence, and be linked so that any later change is detectable. A qualified electronic signature uses a digital certificate under paragraph 1 of article 10 of Provisional Measure 2.200-2. Paragraph 1 of article 4 says the qualified signature has the highest level of reliability. Article 2 says the chapter sets rules for internal interaction of public bodies, for interaction between private persons or private legal entities and those public bodies, and for interaction among those public bodies. The sole paragraph says the chapter does not apply to interaction between natural persons or between private legal entities. inSigner does not issue an ICP-Brasil certificate and is not an accredited certification authority or registration authority. QES for Europe is an Enterprise option and is not an ICP-Brasil qualified signature.

The hash shows whether the final file still matches. It is not an ICP-Brasil certificate, it is not a qualified signature under article 4 of Law 14,063, and it is not a digital time stamp.

No. Essential and Pro use a simple electronic signature. Article 4, item II, of Law 14,063 describes an advanced electronic signature, and item III describes a qualified signature that uses an ICP-Brasil certificate. inSigner does not issue that certificate. QES for Europe is an Enterprise option, priced separately, and it is not an ICP-Brasil signature. It is not on Essential or Pro.

No. Article 10 of the provisional measure is not a filing rule for a public body. Article 5 of Law 14,063 says each public body sets the minimum signature level for documents and interactions with that body. A simple signature may be allowed for low-impact interactions that do not involve classified information. A qualified signature is required for an electronic invoice, except when the issuer is an individual or a micro-entrepreneur (MEI), for the transfer and registration of immovable property, with the commercial-board exception in article 5, paragraph 1, item II, letter c, and in the other cases the law sets, including acts signed by a head of a branch of government or a minister. Article 13 says prescriptions for controlled medicines and electronic medical certificates are valid only with a qualified signature of the health professional. Article 17-A, added by Law 14,620 of 2023, says certain real-estate credit instruments may use an advanced or a qualified signature. Article 108 of the Civil Code requires a public deed for many transfers of real rights over immovable property above the threshold the article sets. inSigner does not issue an electronic invoice, does not file a property transfer, and does not act as a notary or a commercial board. Your counsel decides the form a document needs.

Not by itself. Paragraph 2 of article 10 is met when the parties admit the means as valid, or when the person against whom the document is used accepts it. Accepting the electronic process in inSigner records consent to sign that document. It does not, by itself, prove that a third person admitted the means, and it is not the signature level a public body requires under article 5 of Law 14,063.

No. For the documents you send, you decide the purpose. inSigner does not write your privacy notice and does not make a workflow comply with Law 13,709 of 2018, the LGPD.
