Comply with NOM-151 and Avoid Risks in Your Electronic Documents

In the digital era, secure and reliable management of electronic documents is a priority for businesses and professionals. The authenticity and protection of digital files are essential to prevent fraud and ensure the validity of contracts, invoices, and other legal documents. This is where NOM-151 plays a key role. In this article, we’ll explain how to comply with NOM-151, its benefits, and how this standard can help you minimize risks associated with electronic documents.

What is NOM-151 and Why Is It Important?

NOM-151, or the Official Mexican Standard NOM-151-SCFI-2016, is a regulation that sets the requirements for data preservation and the generation of digital documents with legal validity. In simple terms, it ensures that an electronic document maintains its integrity and cannot be altered without leaving evidence. This standard is especially useful for documents that require authenticity and permanence over time, such as contracts, fiscal receipts, or minutes.

Complying with NOM-151 provides legal certainty to electronic documents, preventing legal issues and facilitating audits. The standard requires documents to include a timestamp, which is obtained through a Certification Service Provider (PSC) authorized by the Mexican Ministry of Economy.

What is a Certification Service Provider (PSC)?

An authorized PSC is an entity validated by the Ministry of Economy to certify the authenticity of electronic documents through timestamping. These timestamps confirm the date and time a document was created, ensuring that any subsequent alteration will be recorded.

At Contractualis, we ensure that documents signed on the platform comply with NOM-151 by working with a PSC authorized by the Ministry of Economy. This guarantees that every document managed on our platform has legal backing and protection against possible modifications, providing peace of mind for our users.

Why Comply with NOM-151?

Complying with NOM-151 is a crucial preventive measure to avoid risks such as document falsification or tampering. Here are some key benefits of adopting this standard:

  • Security and Authenticity: NOM-151 ensures that the document remains intact from the moment it is created, preventing tampering.
  • Legal Validity: Complying with NOM-151 gives documents legal recognition, which is essential in legal or audit processes.
  • Trust in Digital Transactions: In business, it’s crucial to show that a document hasn’t been altered. Complying with NOM-151 promotes transparency and trust between the parties involved.
  • Optimization of Digital Processes: By ensuring document security, businesses can adopt digital processes without worrying about the validity or protection of their files.

By choosing solutions like Contractualis, which comply with NOM-151, you not only protect your documents but also strengthen your business relationships by offering transparency and commitment.
