Are electronic signatures legal in the Dominican Republic?
Yes. The Dominican Republic's Ley 126-02 says information can't be denied legal effect just because it's in digital form, and lets a qualifying digital signature carry the force of a handwritten one. A 2025 regulation from INDOTEL, the telecoms regulator, now maps those rules onto simple, advanced and qualified signatures.

Ley 126-02
The Law on Electronic Commerce, Documents and Digital Signatures (Ley 126-02) was promulgated on September 4, 2002 and took effect on publication (art. 62). Its implementing regulation is Decreto 335-03 of April 8, 2003, whose recitals say the law rests on the UNCITRAL model laws. The main rules:
- Information can't be denied legal effect, validity or binding force solely because it's a digital document or data message (art. 4).
- A legal writing requirement is met by a digital document whose information is accessible for later consultation (art. 5).
- Where a law requires a signature, a digital document meets it if it's digitally signed in line with the law's validity requirements (art. 6).
- Digital documents are admissible as evidence, with the probative force the Civil Code gives private signed instruments (art. 9).
When a signature equals a handwritten one
Article 31 gives a digital signature the same force and effect as a handwritten one if it's unique to the signer, can be verified, is under their exclusive control, is linked to the document so that any change invalidates it, and conforms to the executive's regulations. Once a digital signature is affixed, the signer is presumed to have intended to be bound (art. 33). Article 32 adds a stronger "secure digital signature", verified under a security procedure that meets the law and its regulation.
| Level | In Ley 126-02 and Decreto 335-03 |
|---|---|
| Simple | The electronic signature the parties agree on, which lacks one of a digital signature's requirements (Decreto 335-03, art. 1) |
| Advanced | A digital signature with the art. 31 attributes |
| Qualified | A secure digital signature (art. 32) |
Read the 2025 norm alongside the law
INDOTEL's July 2025 norm on trust services says no level can be denied legal effect or admissibility, but treats only the qualified level as equal to a handwritten signature. That sits uneasily with article 31 of the law, so ask a Dominican lawyer how a court would read them together.
Exclusions
Article 1 leaves out only two things: the State's obligations under international treaties, and warnings the law requires to be printed on risky products. Ley 126-02 doesn't list wills, family law or real estate, so form rules in the Civil Code and other laws, such as notarial requirements, decide those. INDOTEL authorizes and supervises certification entities (art. 56).
Where SignMaster fits in the Dominican Republic
SignMaster provides electronic signatures with an audit trail: the simple level, an agreed method rather than a certificate-based digital signature from an INDOTEL-authorized entity. Make the agreement explicit in your contract. Each completed PDF ends with a certificate of completion recording each signer's email, IP address, consent and timestamps, and a SHA-256 fingerprint of each file shows whether anything changed. It suits service agreements, quotes, supplier contracts and NDAs.
Questions? Answers.
Is an e-signed contract valid in the Dominican Republic?
Yes. Ley 126-02 bars denying legal effect to information solely because it's digital (art. 4), and digital documents are admissible with the force of private signed instruments (art. 9). How much a simple signature proves depends on the evidence behind it.
Who regulates digital signatures in the Dominican Republic?
INDOTEL, the Dominican Telecommunications Institute, authorizes and supervises certification entities under article 56 of Ley 126-02 and issued the 2025 trust services norm.
Does Ley 126-02 exclude wills or property deeds?
Not expressly; its only exclusions are treaty obligations and mandatory product warnings. Other laws' form rules, including notarial requirements, still decide whether those documents can be electronic.
