Legal framework in South Africa
Section 13 of ECTA (Act 25 of 2002) governs electronic signatures and recognizes two types: the standard one and the advanced one (accredited by the relevant authority). A signature doesn't lose legal effect merely for being electronic.

Standard electronic signature
The 2002 ECTA recognizes it broadly: data linked to the document with intent to sign. Valid for most private contracts with reliability evidence.
Advanced electronic signature (AES)
Issued under South African accreditation. It is mandatory where a law requires a signature for certain acts, such as suretyships.
What makes a signature valid in South Africa?
ECTA excludes acts such as the alienation of immovable property, long leases and bills of exchange. For the rest, Firmiu backs each signature with IP, device, location and verification.
