Is e-signature legal in Argentina? A 2026 overview
Short answer: yes. Argentina has recognized e-signatures since 2001 under Ley 25.506 (Ley de Firma Digital) and modernized the regime via Decreto 182/2019. For most commercial contracts, simple e-signatures are valid and accepted by Argentine courts.
This is a brief English overview. The full guide is in Spanish and covers the framework in depth for LATAM readers.
The Argentine two-tier distinction
Argentina makes an important distinction unique in the region:
- Firma electrónica — broad concept, any electronic data used by the signer for identification. Valid in court, but the party presenting it must prove authorship and integrity.
- Firma digital — PKI-based signature using a certificate from a licensed certifier (ARCERT, AC ONTI, etc.). Carries a legal presumption of authorship and integrity — the burden flips to whoever challenges it.
Both are legal. The difference is litigation cost, not validity.
What CAN be e-signed (with simple e-signature)
Standard B2B commerce: services agreements, NDAs, freelance contracts, software licenses, MSAs, SOWs, change orders, employment offer letters, lease agreements (movables), letters of intent.
What CANNOT be e-signed (or requires firma digital)
Per article 4 of Ley 25.506, excluded acts include:
- Wills (disposiciones por causa de muerte)
- Family law acts (marriage, adoption)
- Personalísimos acts
- Acts requiring escritura pública
Some government processes (AFIP, judicial filings via Lex 100/SISFE, IGJ in some provinces) require firma digital specifically.
SignQuick in Argentina
SignQuick is ESIGN/UETA compliant. For Argentine commercial counterparties, SignQuick signatures qualify as firma electrónica under Ley 25.506 — valid in court, with full audit trail (SHA-256 document hashes, RFC 3161 timestamps, IP, geolocation, user agent, explicit ESIGN/UETA consent) supporting authorship and integrity claims.
It is not a substitute for firma digital certificada — for AFIP filings, judicial filings, or government processes that require it specifically, you'll need a licensed Argentine certifier.
