Are E-Signatures Legally Valid in South Africa?

The short answer is yes— electronic signatures are legally valid and enforceable in South Africa for the vast majority of commercial documents. Here's everything your business needs to know.

The governing law: ECT Act 25 of 2002

Electronic signatures in South Africa are governed by the Electronic Communications and Transactions (ECT) Act 25 of 2002. Section 13 of the Act explicitly recognises that a requirement in law for a signature is satisfied by an electronic signature, provided the method used is reliable and appropriate for the purpose.

This means that for most everyday commercial and civil documents — service agreements, employment contracts, NDAs, lease agreements, purchase orders, engagement letters — an electronic signature has exactly the same legal weight as a handwritten signature.

Types of electronic signatures under the ECT Act

The ECT Act recognises two categories of electronic signatures:

• Electronic signature (Section 13): Any data attached to or associated with a document that is intended to serve as a signature. This is what SignZA uses — a name, IP address, timestamp, and document fingerprint captured at the time of signing.
• Advanced electronic signature (Section 13(3)): A higher-assurance signature using an accredited authentication service, required for a small number of specific document types (see below).

What SignZA's audit trail captures

Each signed document produced by SignZA includes a certificate of completion that records:

• The signer's full name (as entered)
• The signer's email address
• The signer's IP address at time of signing
• The device and browser used
• The exact date and time of each action (email opened, document viewed, signed)
• A cryptographic hash of the document — proving it has not been altered since signing

This audit trail is what makes the signature enforceable in a dispute. If a signatory later claims they did not sign, the audit trail provides clear evidence of their identity and intent.

When you still need an advanced electronic signature or wet ink

A small number of document categories require either an advanced electronic signature or a traditional wet ink signature. These include:

• Wills and testamentary documents
• Negotiable instruments (e.g. cheques, bills of exchange)
• Deeds of sale for immovable property (though initial agreements of sale can be electronic)
• Divorce agreements and certain family law documents
• Documents requiring a Commissioner of Oaths or notarisation

If you are unsure whether your specific document requires wet ink or an advanced electronic signature, consult your attorney.

Signed documents are retained for 7 years

SignZA retains all signed documents and their audit trails for 7 years from the date of signing, in line with South African legal record-keeping requirements. You can download your documents at any time from your dashboard.

Frequently asked questions

Can a signed document be disputed in court?

Any document can theoretically be disputed. However, SignZA's audit trail — capturing the IP address, device, timestamp, and document hash — provides strong evidence of intent and identity. The burden of proof shifts significantly to the party disputing the signature.

Does the signer need to consent to e-signing?

By proceeding with the signing process (clicking the link, reviewing the document, and confirming their signature), the signer implicitly consents. SignZA's signing page includes a clear legal confirmation statement before the signature is finalised.

Is there a difference between a digital signature and an electronic signature?

Yes. A digital signatureuses cryptographic public-key infrastructure (PKI) to bind a person's identity to a document — it is a technical implementation. An electronic signature is the broader legal concept under the ECT Act. SignZA uses electronic signatures supported by a robust audit trail, which is legally sufficient for Section 13 purposes.
