Are electronic signatures legal in Colombia?
Yes. In Colombia an electronic signature has the same validity and legal effects as a handwritten signature, as long as the method is reliable and appropriate for the purpose. When the parties agree in advance on how they'll sign, the law presumes their method meets that test.

Ley 527 de 1999
Ley 527 de 1999 governs data messages, electronic commerce and digital signatures. It was published in the Diario Oficial on August 21, 1999 and follows the UNCITRAL Model Law on Electronic Commerce; article 3 asks courts to read it in light of that international origin, as the Constitutional Court noted in ruling C-662 of 2000. Three rules carry most of the weight:
- Information can't be denied legal effect, validity or binding force just because it's a data message (art. 5).
- Where the law requires a signature, a data message meets it if a method identifies the sender, shows their approval, and is as reliable as it is appropriate for the purpose (art. 7).
- Data messages are admissible as evidence (art. 10), and the General Code of Procedure presumes documents in the form of data messages authentic (art. 244).
Electronic and digital signatures
| Firma electrónica | Firma digital | |
|---|---|---|
| Basis | Ley 527, art. 7; Decreto 2364 de 2012 | Ley 527, arts. 2(c) and 28 |
| What it is | Codes, passwords, biometric data or private keys that identify a person, if reliable and appropriate (Decreto 2364, art. 1(3)) | A numeric value attached to the message, computed with a known mathematical procedure from the signer's key, that shows the message hasn't changed |
| Effect | Same validity and effects as a signature when it meets art. 3 of the decree (art. 5) | Same force as a handwritten signature when it meets the five attributes in art. 28 |
Decreto 2364 is now compiled in Decreto 1074 de 2015 (arts. 2.2.2.47.1 and following). It says a signature is reliable when the signing data belong only to the signer and any later change to the message can be detected (art. 4). Under article 7, methods the parties agree on are presumed to meet the requirements unless proven otherwise, and the party that supplied the method must be able to prove it's secure and reliable.
Digital certification entities are accredited by the national accreditation body, ONAC, and supervised by the Superintendence of Industry and Commerce. For court cases, Ley 2213 de 2022 (art. 5) lets a party grant a power of attorney by data message with just their typed name, no handwritten or digital signature needed.
Exclusions
Ley 527's article 1 excludes only two things: the Colombian State's obligations under international treaties, and written warnings that the law requires to be printed on certain products because of their risk. Other laws still set their own form requirements, so a document that must be a public deed still goes through a notary.
Where SignMaster fits in Colombia
SignMaster provides firma electrónica with an audit trail, not a certificate-based firma digital. Because Decreto 2364 presumes an agreed method valid, write into your contract that both parties accept signing through SignMaster, and keep the evidence. Each completed PDF carries a certificate of completion listing each signer's email, IP address, consent and timestamps, and a SHA-256 fingerprint of each file shows whether anything changed after signing, the alteration test article 4 sets.
Questions? Answers.
Is a firma electrónica as valid as a handwritten signature in Colombia?
Yes, when the method is reliable and appropriate for the purpose (Decreto 2364, arts. 3 and 5). A method the parties agreed on is presumed to meet that test unless someone proves otherwise (art. 7).
Do I need a firma digital for business contracts in Colombia?
Usually not. Ley 527 and Decreto 2364 are technology neutral, so a reliable electronic signature works. A firma digital adds stronger presumptions and is required where a specific rule calls for it.
Who accredits digital signature providers in Colombia?
The Organismo Nacional de Acreditación de Colombia (ONAC) accredits digital certification entities, and the Superintendence of Industry and Commerce supervises them.
