Types of electronic signature in Puerto Rico
Electronic signature
Any electronic symbol or process adopted with intent to sign (Act 148-2006 and the federal ESIGN Act). Its validity depends on proving intent and process — the role of Firmiu's audit trail.
Remote notarization
For documents that require a notary, Puerto Rico has enabled remote execution mechanisms. Ordinary contracts don't need it.
What makes a signature valid in Puerto Rico?
A valid signature requires intent to sign, consent and a record of the process. Firmiu's audit trail — IP, device, location, timestamp and verification — meets those requirements.
