eSignature legality summary
A written signature is not required for a valid contract; the E-Signature Law confirms a contract is not unenforceable merely for being electronic, and electronic records are admissible where they comply with the General Regulation (ss. 10, 16, 17).
Types of permitted electronic signature
Ecuador recognizes only a qualified electronic signature (QES) — a government-certified digital signature created with a secure signature-creation device. Foreign certificates must be revalidated by a locally accredited certification agency; non-accredited agencies must disclose that status.
Documents that may be signed electronically
Many transactions are eligible but must use a QES — commercial agreements (NDAs, sales, service), consumer agreements, employee confidentiality/invention agreements, insurance policies, public-entity certificates, software licenses, and tax documents.
Use with caution / not typically appropriate
A signature that does not comply with the E-Signature Law’s requirements is invalid, compromising enforceability; verify accreditation of the certificate provider.
