eSignature Legality in Uruguay

E-Signature Legality Summary

This guide explains the electronic-signature framework in Uruguay, including the governing laws, legal effect, accepted signature methods, validity requirements, exclusions and practical business uses.

Applicable Laws

Law No. 18,600 on Electronic Documents and Electronic Signatures

Legal Status

Electronic records and signatures receive legal recognition in Uruguay under Law No. 18,600 on Electronic Documents and Electronic Signatures. The signing process must also satisfy every document-specific rule on identity, evidence, delivery, retention, witnessing, notarization, registration or filing.

Regulatory Authority

The competent regulator is the Agency for Electronic Government and Information and Knowledge Society (AGESIC), through its Electronic Certification Unit (UCE), which is specifically responsible for electronic-signature supervision.

Legal Recognition (Effect)

The legal effect of an electronic signature is assessed under Law No. 18,600 on Electronic Documents and Electronic Signatures. The assessment covers signer intent, reliable attribution, integrity of the signed record and compliance with every prescribed form for the document or transaction.

Accepted Types of Electronic Signatures

Advanced electronic signature (including AES and QES)

Electronic signature: data in electronic form attached to or logically associated with an electronic document, used for the identification of the signatory.

Advanced electronic signature: an electronic signature that meets the following requirements:

1. it is required to contain information unique to the signatory so that the signatory can be uniquely identified;

2. it must be created in a manner that the signatory can keep under sole control;

3. it must be capable of being verified by a third party;

4. it is linked to the electronic document in such a way that any subsequent change can be detected; and

5. it is created using a technically secure and reliable signature creation device and based on a recognized certificate valid at the time of signing.

An Electronic Signature (SES) is electronic data attached to or logically associated with an electronic document for identification of the signatory. An Advanced Electronic Signature (AES) must contain information unique to the signatory and identify the signatory uniquely, be created by means under the signatory’s exclusive control, be verifiable by a third party, be linked to the electronic document so that any subsequent alteration is detectable, and be created using a technically secure and reliable signature-creation device based on a public certificate valid at the time of signing.

Legal Requirements for Electronic Signatures

Advanced electronic signature: an electronic signature that meets the following requirements:

1. it is required to contain information unique to the signatory so that the signatory can be uniquely identified;

2. it must be created in a manner that the signatory can keep under sole control;

3. it must be capable of being verified by a third party;

4. it is linked to the electronic document in such a way that any subsequent change can be detected; and

Limitations and Exceptions

An advanced electronic signature is required in notarial work and in use scenarios involving state agencies (Articles 7 and 8 of Law No. 18600).

For marriage, wills, trusts, real-estate transactions and government filings, identify and complete every statutory formality before using an electronic process.

Industry Applications and Typical Use Cases

Supported in most scenarios

Electronic signatures support commercial contracts, sales and procurement, employment documentation, internal approvals and customer onboarding when the governing document and sector rules are satisfied.

For regulated or cross-border workflows, record the governing law, required assurance level, signer-authentication method, evidence package, retention period and receiving-party requirements before launch.
