E-signature legality · South Africa
Are electronic signatures legal in South Africa?
Reviewed
In short
Yes, with conditions. Under the Electronic Communications and Transactions Act 25 of 2002, an electronic signature isn't denied legal force just because it is electronic, and where the parties themselves require a signature, any reliable method that identifies the person and shows approval is generally enough. But where a law requires a signature without specifying its type, only an accredited advanced electronic signature satisfies it. The Act also doesn't validate electronic wills, land-sale agreements, long leases or bills of exchange.

In practice
Things to know
Every PDFBetter signer signs with their own cryptographic key: their browser generates an ECDSA P-256 key that never leaves the device and signs a statement binding the document's SHA-256 fingerprint to exactly what they entered, and PDFBetter's certificate authority certifies that key. Every completed PDF and its certificate of completion are digitally sealed with a PAdES signature and, when the service is reachable, independently time-stamped under RFC 3161, so any change shows in PDF readers. The evidence is built into the file: signed statements, device signatures, certificates, entered values and a hash-chained audit log of every view, consent, signature and decline with time and IP address. Signers consent to sign electronically first, the sender can require an emailed 6-digit code, and completed evidence is kept for 7 years. Signature requests are designed to the technical requirements of an advanced electronic signature (eIDAS art. 26): a unique key per signer, under their sole control, linked to the document so any change is detectable. Signers are identified by email (and an optional emailed code), not by ID documents or SMS.
South Africa is stricter than many countries where a statute, rather than the parties, requires a signature: only an advanced electronic signature from a product accredited under the ECT Act meets that requirement. PDFBetter is not an accredited advanced electronic signature product.
PDFBetter does not create qualified electronic signatures (QES) and does not offer SMS codes, phone authentication, knowledge-based questions or government ID checks. Its seal certificate comes from PDFBetter's own certificate authority, not a government-accredited one, and is not yet on Adobe's trust list, so Acrobat shows the seal's identity as not verified while still detecting changes. Where a law requires a qualified or accredited signature, verified identity, a notary, wet ink or a witness, use a process that provides it.
This page summarizes what the law generally says, with links to the official texts. PDFBetter is not a law firm; for an important or unusual document, check with a lawyer qualified where the document will be relied on.
