Is an electronic signature legal in Uruguay?
A written signature is not required for a valid contract — parties can agree verbally, electronically, or on paper (Civil Code Art. 1252) — and electronic records are admissible in evidence. Uruguay uses tiers: a standard electronic signature (SES), an advanced electronic signature (AES), and a qualified electronic signature (QES).
What types of electronic signature are recognized in Uruguay?
An SES suits most ordinary documents. An AES is uniquely linked to and identifies the signatory, is under their sole control, and is tamper-evident. A QES is a government-certified, device-based implementation, required for securities (títulos valores).
What documents can be signed electronically in Uruguay?
With an SES: HR documents, commercial agreements (NDAs, purchase orders, procurement, sales, distribution, service), consumer agreements, residential and commercial leases (except residential-lease termination notices), and software/IP licenses and transfers.
What documents cannot be signed electronically in Uruguay?
An AES is required for higher-stakes matters — contracts over ~100 Readjustable Units, defined-term labor contracts, loan-interest agreements, settlements, rural-estate leases and sharecropping, and insurance — and a QES for securities.
