Electronic signatures in MexicoBuilt for business
across Mexico.

For commercial matters, article 89 of the Commercial Code says the title applies throughout the Republic, without prejudice to treaties, and that commercial acts may use electronic, optical, or any other technology. The same article defines an electronic signature as data in electronic form placed in a data message, or attached to it or logically associated with it, used to identify the signer and to show that the signer approves the information. It states that this signature produces the same legal effects as a handwritten signature and is admissible as evidence. Article 89 bis says legal effects, validity, or binding force are not denied solely because the information is in a data message, if the message follows the Code and the corresponding rules. Article 93 says a writing requirement is satisfied when the information stays intact and accessible for later consultation, and that a signature requirement is satisfied for a data message when the message is attributable to the parties. Article 96 says the Code is applied so as not to exclude any method of creating an electronic signature. Article 97 says that when the law requires a signature, or the parties agree to one, the requirement is satisfied if the electronic signature is appropriate for the purposes for which the message was generated or communicated. The standard inSigner signature is an electronic signature. It is not an advanced or reliable electronic signature under fractions I to IV of article 97. Whether it is appropriate still depends on the document and the law that governs it. inSigner does not decide that question.

Article 89 defines an advanced or reliable electronic signature as an electronic signature that meets fractions I to IV of article 97. Those fractions require that the signature creation data correspond exclusively to the signer in the context in which they are used, that they were under the signer's exclusive control at the time of signing, that any later alteration of the signature can be detected, and that any later alteration of the information in the data message can be detected. The same article says anyone may prove reliability in another way, or prove that a signature is not reliable. The Advanced Electronic Signature Law was published in the Official Journal on 11 January 2012. Article 2, fraction XIII, defines that signature as data and characters that identify the signer, created under the signer's exclusive control, linked only to the signer and to the data, so that a later change can be detected, and that produce the same legal effects as a handwritten signature. Article 7 says a document or data message that has an advanced electronic signature produces the same effects, and the same evidentiary value, as one presented with a handwritten signature. Article 1 and article 3 cover acts in which private persons and federal public servants use that signature. Article 4 says the law does not apply to tax, customs, and financial matters, and that commercial acts and entries in the Public Registry of Commerce follow the Commercial Code. The tax authority's e.firma, formerly called FIEL, is a certificate for tax filings. inSigner does not issue it and is not an accredited certification provider. QES for Europe is an Enterprise option and is not a Mexican advanced electronic signature.

Each person signs the fields you placed on the document you sent. The evidence record keeps their name and email or phone, when the document was sent, viewed, and signed, the IP address, the device data, and the authentication used.

Yes. You can download the completed PDF and the evidence record, including a SHA-256 hash of the final file. If a single byte changes, the hash no longer matches. The hash shows whether the final file still matches. It is not a conservation certificate under NOM-151-SCFI-2016, and it is not a digital time stamp. Article 93 bis is about a reliable assurance of integrity when information must be presented or kept in original form. The hash does not by itself decide that article. Article 95 bis 2 says that keeping data messages under the merchant's own control, so they can be consulted later, is the merchant's responsibility.

No. Essential and Pro use a simple electronic signature. Fractions I to IV of article 97 describe an advanced or reliable electronic signature. NOM-151-SCFI-2016, published in the Official Journal on 30 March 2016, is the official standard on digitization and conservation of data messages. Articles 100 and 101 reserve conservation certificates, digital time stamps, and digitization for a certification provider accredited by the Ministry of Economy. inSigner does not issue a constancia de conservación. QES for Europe is an Enterprise option, priced separately, and it is not a Mexican advanced electronic signature. It is not on Essential or Pro.

No. Article 89 limits the title to commercial matters. It is not a general rule for a civil, family, or labor act, and many non-commercial acts follow a state civil code. The third paragraph of article 93 does not remove a requirement that an act be granted in a public instrument. A notary and the parties may express the terms in data messages. The notary must record how those messages are attributed, keep an intact version for later consultation, and grant the instrument under the notarial law. inSigner does not act as a notary or a commercial broker, does not witness a signature, and does not file a document in a property registry or in the Public Registry of Commerce. Negotiable instruments follow the General Law of Negotiable Instruments and Credit Operations. inSigner does not decide whether that form is met. Your counsel decides the form a document needs.

Not by itself. Article 93 satisfies a writing requirement when the information remains intact and accessible for later consultation, and a signature requirement when the data message is attributable to the parties. Accepting the electronic process in inSigner records consent to sign that document. It does not, by itself, decide attribution under article 93, and it is not an advanced electronic signature for a procedure before a federal public body. Article 3 of the Advanced Electronic Signature Law covers public servants and private persons when they use an advanced electronic signature in the acts that law covers. The e.firma is a different certificate.

No. For the documents you send, you decide the purpose. inSigner does not write your privacy notice and does not make a workflow compliant with the Ley Federal de Protección de Datos Personales en Posesión de los Particulares, which article 95 bis 1 still names for information held by a certification provider.
