Short answer: yes, but the type of signature matters. Argentina's Ley 25.506 recognizes both firma electrónica and firma digital. An ordinary electronic signature can support proof that someone accepted a private agreement, while a qualifying digital signature receives stronger statutory presumptions.

The electronic medium does not eliminate a public-deed, registration, certified-signature, or other formality required for the underlying transaction.

Legal sources last reviewed July 29, 2026.

Three sources shape the analysis:

  • Ley 25.506: Article 1 recognizes electronic and digital signatures. Article 3 says a qualifying digital signature satisfies a legal requirement for a handwritten signature. Article 5 defines an electronic signature and places the burden of proving it on the party relying on it if the signature is denied.
  • Digital-signature presumptions: Articles 7 and 8 presume authorship and document integrity for a valid digital signature, subject to contrary proof. Article 9 ties validity to a current certificate issued or recognized by a licensed certifier.
  • Civil and Commercial Code: Articles 286 and 288 recognize electronic written expression but say the requirement for a person's signature on an electronically generated instrument is satisfied by a digital signature that reliably assures authorship and integrity.

The Decreto 182/2019, as amended, regulates the national digital-signature infrastructure, licensed certifiers, remote digital signing, trust services, and record preservation.

“Electronic” and “digital” are therefore not interchangeable labels in Argentine law. A typed name, drawn signature, approval button, or commercial platform record may be evidence of assent without becoming a firma digital.

When an ordinary electronic signature may be appropriate

An ordinary platform workflow is often considered for private agreements that have no special statutory form, such as many:

  • service and freelance agreements;
  • NDAs and confidentiality agreements;
  • software subscriptions and licenses;
  • statements of work and change orders;
  • purchase orders and routine B2B agreements; and
  • letters of intent.

That is not a universal list of “automatically valid” documents. The parties' identity and intent, the agreement itself, governing law, transaction value, evidence, and any sector-specific rule still matter.

When a signing platform alone is not enough

Article 4 of Ley 25.506 excludes:

  • dispositions upon death;
  • family-law acts;
  • highly personal acts; and
  • acts subject to requirements or formalities incompatible with digital signing.

Other transactions may require a public deed, notarization or signature certification, registration, a government portal, or a licensed digital signature. Real-estate dispositions, wills, powers, corporate acts, employment documents, court filings, tax procedures, and regulated transactions should be checked individually.

The careful rule is not “these documents can never be electronic.” It is that an ordinary platform signature does not replace an additional legal formality.

What evidence should be retained?

If an electronic signature is denied, Article 5 makes evidence especially important. A defensible record should connect the person, the approval, and the final document:

  • the final document and a tamper-evident hash;
  • the signer's identity and authentication evidence;
  • an explicit record of intent to sign;
  • timestamps, delivery records, IP, and user-agent evidence where lawful and proportionate;
  • the version of the agreement and disclosure shown to the signer; and
  • a complete audit trail that can be exported and retained.

A pasted image alone is easier to copy and usually proves less than a controlled signing workflow.

Can a foreign platform be used?

A platform is not automatically accepted or rejected because its company or servers are outside Argentina. For an ordinary electronic signature, the useful question is whether the complete record proves identity, assent, and integrity.

US ESIGN/UETA compliance may matter to a US party, but it is not the Argentine legal test. Foreign digital certificates also follow the separate recognition rules in Article 16 of Ley 25.506.

How SignQuick supports the evidence

SignQuick records consent, signer activity, timestamps, IP and user-agent evidence, SHA-256 document hashes, and an audit-trail PDF. It also records the result of its third-party RFC 3161 timestamp request.

Those records can support an Argentine firma electrónica analysis. They do not guarantee enforceability, create a licensed Argentine firma digital, or replace a public deed, government portal, court system, or transaction-specific formality.

Frequently asked questions

Are electronic signatures legal in Argentina?

Yes. Ley 25.506 recognizes both electronic and digital signatures, but they have different evidentiary effects. If an electronic signature is denied, the party relying on it must prove its validity.

Is an electronic signature the same as a digital signature in Argentina?

No. A digital signature must satisfy Ley 25.506 and use a valid certificate issued or recognized within Argentina's licensed infrastructure. It receives presumptions of authorship and document integrity that an ordinary electronic signature does not.

Can I use a foreign signing platform for a contract with an Argentine client?

A foreign platform may provide evidence of assent for an ordinary private agreement, but its origin or US compliance does not guarantee enforceability. The transaction's formalities, governing law, evidence, and any requirement for a licensed digital signature still control.
