Electronic signature in Argentina

Is the electronic signature legal in Argentina?

Yes. Electronic signatures are legal and valid in Argentina. The framework was set by Law 25,506 of 2001 on Digital Signatures, reinforced by the Civil and Commercial Code, which recognises that an act may be recorded in an electronic document instead of on paper (art. 1106). A document signed with SignaSuite has legal effect, provided the method identifies the signer and preserves the integrity of the content.

Unlike other countries, Argentine law draws a clear distinction between two concepts: the digital signature (which enjoys a presumption of authorship and integrity) and the electronic signature (valid, but with a different burden of proof). Both produce legal effects; the difference is evidentiary, as explained below.

Legal framework for electronic and digital signatures in Argentina

• Law 25,506 of 2001 (Digital Signature) — Defines the digital signature and the electronic signature, their requirements and the presumption of authorship and integrity of the digital signature.
• Civil and Commercial Code (art. 288) — States that, in electronic instruments, the signature requirement is met with a digital signature that ensures authorship and integrity, which may replace the handwritten one.
• Civil and Commercial Code (art. 314) — Governs the acknowledgement of the signature and the evidentiary value of private instruments.
• Civil and Commercial Code (art. 1106) — Allows the written-form requirement to be met through electronic means in contractual matters.
• Decree 182/2019 and Decree 892/2017 — Implement the Digital Signature Infrastructure and regulate the remote digital signature.
• Resolution MTEySS 1455/2011 — Authorises the issuance of pay slips in digital or electronic format in the employment field.

Types of signature recognised in Argentina

Digital signature vs. electronic signature in Argentina

This is the most important distinction in Argentine law. The key lies in the burden of proof:

• The digital signature automatically carries authorship and integrity thanks to a licensed certifier. It is presumed valid unless proven otherwise (arts. 7 and 8), and the burden of proof falls on whoever challenges it.
• The electronic signature is more flexible and needs no licensed certificate: it is valid, but if challenged, the party invoking it must prove its validity with the technical evidence generated (signature audit, time stamp, traceability, etc.).

That is why SignaSuite backs every electronic signature with robust evidence — two-factor (OTP), biometric analysis, time stamps and an audit trail — that supports its evidentiary value in court.

Which documents can be signed electronically in Argentina?

Evidentiary value: does an electronic signature hold up before an Argentine judge?

Yes. The digital signature enjoys a presumption of authorship and integrity (arts. 7 and 8 of Law 25,506): it is presumed valid unless proven otherwise and gives the document the same evidentiary status as an instrument signed in writing (art. 314 of the Civil and Commercial Code). The electronic signature is also admissible as evidence, but if it is denied or challenged, the party invoking it must prove its validity. The stronger the technical evidence — robust authentication, integrity secured by a time stamp and full traceability — the greater the document's evidentiary weight.

SignaSuite generates a self-contained evidence record for every signed document, helping to demonstrate authorship, integrity and non-repudiation, ready to be submitted in legal proceedings.

Frequently asked questions about electronic signatures in Argentina

Which law governs electronic signatures in Argentina?

The framework law is Law 25,506 of 2001 on Digital Signatures, complemented by the Civil and Commercial Code (arts. 288, 314 and 1106) and, in the employment field, by Resolution MTEySS 1455/2011.

Does an electronic signature have the same validity as a handwritten one?

The digital signature replaces the handwritten one and enjoys a presumption of authorship and integrity (art. 288 of the Civil and Commercial Code). The electronic signature is valid, but if challenged, the party invoking it must prove its validity with the associated technical evidence.

What is the difference between a digital and an electronic signature in Argentina?

The digital signature is created with a certificate from a licensed certifier and enjoys a legal presumption of authorship and integrity. The electronic signature is more flexible and does not require that certificate, but its validity must be proven if questioned.

Do I need a certificate to sign electronically?

Not for the electronic signature. A licensed certifier's certificate is only required for the digital signature. An electronic signature backed by robust evidence, like SignaSuite's, is valid without it.

Which documents cannot be signed electronically in Argentina?

Acts requiring a handwritten signature or a specific form: wills and strictly personal acts, corporate minutes with shareholder or board resolutions, and employee resignation letters (which require a certified letter under art. 240 of the Employment Contract Law).

Are electronic pay slips valid in Argentina?

Yes. Resolution MTEySS 1455/2011 authorises employers to issue pay slips in digital or electronic format, replacing the paper version.
