# Electronic signatures in South Africa

Electronic signatures are valid for most business agreements in South Africa: the Electronic Communications and Transactions Act 25 of 2002 (ECTA) says an agreement or an electronic signature is not without legal force merely because it is electronic, and the Supreme Court of Appeal has held that typed names met a signing requirement the parties had set themselves. Only where a law itself requires a signature, a notarised act or a seal does the Act demand an accredited advanced electronic signature, and land sales, leases over 20 years, wills and bills of exchange fall outside it; for everyday contracts, what counts is evidence of who signed what, which Attest records with each signer's own passkey signature.

## The law: the ECT Act

The **Electronic Communications and Transactions Act 25 of 2002** ([ECTA](https://www.gov.za/sites/default/files/gcis%5Fdocument/201409/a25-02.pdf)) was published in Government Gazette No. 23708 of August 2, 2002 and came into force on August 30, 2002. It applies to any electronic transaction or data message (section 4(1)). Its core rules:

- "An agreement is not without legal force and effect merely because it was concluded partly or in whole by means of data messages" (section 22(1)).
- An electronic signature "is not without legal force and effect merely on the grounds that it is in electronic form", subject to the rule for signatures a law requires (section 13(2)).
- A legal requirement that a document be in writing is met by a data message that is accessible in a manner usable for subsequent reference (section 12).
- Nobody has to go electronic, and a person may set their own requirements for the data messages they accept (section 4(2)).

[gov.za](https://www.gov.za/documents/electronic-communications-and-transactions-act) lists two amending Acts (the Consumer Protection Act 68 of 2008 and the Cybercrimes Act 19 of 2020); the sections quoted here are from the Act as published in the Gazette.

## Electronic and advanced electronic signatures

The Act has two kinds of signature, and the difference decides where each one works.

|                           | Electronic signature                                                                                                                                                                                            | Advanced electronic signature                                                                                                                                                                                                                                                                                                                                                         |
| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Definition (section 1)** | "data attached to, incorporated in, or logically associated with other data and which is intended by the user to serve as a signature"                                                                          | "an electronic signature which results from a process which has been accredited by the Authority as provided for in section 37"                                                                                                                                                                                                                                                       |
| **What it takes**          | Where the parties require a signature but haven't agreed on its type: a method that identifies the person and indicates their approval, as reliable as was appropriate in all the circumstances (section 13(3)) | An authentication product or service accredited by the Accreditation Authority (section 37), which must be satisfied that the signature is uniquely linked to the user, capable of identifying them, created with means under their sole control, linked to the data so that a later change is detectable, and "based on the face-to-face identification of the user" (section 38(1)) |
| **Effect**                 | Not without legal force merely because it is electronic (section 13(2)), and it meets signing requirements the parties set (section 13(3))                                                                      | The only signature that meets a signature requirement in a law that doesn't specify the type (section 13(1)), and presumed valid and properly applied unless the contrary is proved (section 13(4))                                                                                                                                                                                   |

The Act also requires an advanced electronic signature from the person authorised to notarise, acknowledge, verify or administer an oath, where a law requires that (section 18(1)); to confirm the certification of an electronic copy of a paper document (section 18(3)); and from the person who must seal a document, where a law requires a seal (section 19(3)). There is no higher tier.

## Spring Forest: signatures the parties require

The leading case is [_Spring Forest Trading 599 CC v Wilberry (Pty) Ltd t/a Ecowash_](http://web.archive.org/web/20250518011505/https://www.saflii.org/za/cases/ZASCA/2014/178.html) \[2014\] ZASCA 178, decided by the Supreme Court of Appeal on November 21, 2014. The parties' agreements required cancellation in writing signed by the parties, and they later cancelled by email. The court held:

- Section 13(1) didn't apply, because "the non-variation clauses were agreed upon by the parties: they were not imposed upon the parties by any law" (paragraph 20).
- Section 13(3) did, and "the typewritten names of the parties at the foot of the emails" were data logically associated with the emails, so they "satisfy the requirement of a signature" (paragraph 28).
- The courts' approach to signatures "has therefore been pragmatic, not formalistic": they look at whether the method fulfils the function of a signature (paragraph 26).

So where the signing requirement comes from the contract rather than a statute, an electronic signature works, and the advanced tier is reserved for signatures a law demands. See [is a typed name a legal signature?](https://attest.datahubz.com/legal/is-a-typed-name-a-legal-signature) for other countries.

## Documents excluded or with their own rules

The Act "must not be construed as giving validity to" these transactions (section 4(4) and Schedule 2):

1. an agreement for the alienation of immovable property under the Alienation of Land Act, 1981;
2. an agreement for the long-term lease of immovable property in excess of 20 years under that Act;
3. the execution, retention and presentation of a will or codicil as defined in the Wills Act, 1953;
4. the execution of a bill of exchange as defined in the Bills of Exchange Act, 1964.

Schedule 1 also switches off listed sections of the Act for those laws and the Stamp Duties Act, 1968 (section 4(3)). Beyond these lists:

- **Signatures a statute requires.** Where any law requires a signature without saying which kind, only an advanced electronic signature satisfies it (section 13(1)), so check the law behind a document before signing it electronically.
- **Notarial acts, oaths and seals** need the advanced electronic signature of the notary, commissioner or person who seals (sections 18 and 19(3)).

## Proving an electronic signature

- **Admissibility.** The rules of evidence must not deny a data message's admissibility merely because it is a data message or, if it is the best evidence reasonably obtainable, because it isn't in its original form (section 15(1)).
- **Weight.** A data message "must be given due evidential weight" (section 15(2)), assessed by the reliability of how it was generated, stored or communicated, the reliability of how its integrity was maintained, the manner in which its originator was identified, and any other relevant factor (section 15(3)).
- **Business records.** A data message made in the ordinary course of business is admissible on its mere production and is "rebuttable proof of the facts" it contains (section 15(4)).
- **Presumption.** Only an advanced electronic signature is presumed valid (section 13(4)). With any other electronic signature, the party relying on it shows who signed and what was signed.
- **Retention.** A duty to keep information is met by a data message that stays accessible, in the format in which it was generated, sent or received (or one shown to represent it accurately), with its origin, destination and the date and time it was sent or received determinable (section 16(1)).

## How to make an electronic signature hold up

1. **Check the document.** If it is on Schedule 2, or a statute requires the signature, follow that law's process.
2. **Use a method that identifies each signer and records their approval** (section 13(3)).
3. **Keep evidence of what section 15(3) weighs:** how the signature was made, how integrity was kept and how each signer was identified.
4. **Keep the signed record** in a form that meets section 16.

## How Attest fits ordinary business agreements

Attest signatures are electronic signatures under section 1 of the Act. They are not advanced electronic signatures, which in South Africa require an accredited authentication product and face-to-face identification; each Attest signature is made with a passkey registered to the signer's email address, and Attest confirms control of that address and the passkey, not a government ID. For agreements whose signing requirement comes from the parties, such as client contracts, statements of work, NDAs and supplier agreements, each signature carries evidence aimed at what a court weighs:

| What the court weighs                                    | What Attest records                                                                                                                                                                                                                                                                                                                                                   |
| -------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **How the originator was identified** (section 15(3)(c)) | Each signature is made with a passkey registered to the signer's email address. A passkey is a cryptographic key only the signer controls, unlocked with Face ID, Touch ID, Windows Hello or the device PIN, and it must confirm the signer is present and verified. Attest confirms control of the email address and the passkey, not a government ID                |
| **Approval of the information** (section 13(3)(a))       | The signer reviews the document, and their passkey signs a statement that begins "I have reviewed and I sign", naming the document by its fingerprint. Attest checks each signature against the passkey's public key before recording it                                                                                                                              |
| **How integrity was maintained** (section 15(3)(b))      | The statement includes the SHA-256 fingerprint of the exact document and of the signer's entries, and the signed state is anchored on the Horizen public blockchain. Change one byte and verification fails                                                                                                                                                           |
| **Retention** (section 16(1))                            | Every party downloads the same sealed PDF: the signed pages, with a "Signed with Attest" stamp on each signature and a seal line at the foot of every page, a certificate of completion, the audit trail up to completion in UTC and a "Verify it yourself, without us" page, with the full evidence, the original document and a standalone verifier attached inside |

A **fingerprint** (SHA-256 hash) is a short code calculated from a file's contents that changes if a single byte changes. The open-source verifier inside the copy runs in any browser without any Attest service and checks each signer's passkey signature, the original document, the pages you see and Attest's anchored record on Horizen. As with any evidence, the court decides its weight.

For a signature a statute requires, use an accredited advanced electronic signature; for a document on Schedule 2 or a notarial act, follow the process that law sets.

Every document is end-to-end encrypted, so Attest can't read it. Signers need no account and never pay, and anyone can verify a signed copy for free at [attest.datahubz.com/verify](https://attest.datahubz.com/verify). Your first 2 documents are free, in total, then the Signing plan is $5 a month for 20 documents.

## Questions people ask

Is an electronic signature legally binding in South Africa?

Yes, for most agreements. The ECT Act says an agreement is not without legal force merely because it was concluded by data messages (section 22(1)), and an electronic signature is not without legal force merely because it is electronic (section 13(2)). The exceptions are signatures a statute requires, which need an advanced electronic signature, and the transactions on Schedule 2.

What is an advanced electronic signature in South Africa?

One that results from a process accredited under section 37 of the ECT Act. Accreditation requires, among other things, that the signature is uniquely linked to the user, under their sole control and "based on the face-to-face identification of the user" (section 38(1)). It is presumed valid unless the contrary is proved (section 13(4)).

Is a typed name a valid signature in South Africa?

It can be. In Spring Forest (2014), the Supreme Court of Appeal held that the parties' typed names at the foot of emails satisfied a signing requirement in their own contract, under section 13(3). That works for requirements the parties set; where a statute requires the signature, section 13(1) asks for an advanced electronic signature.

Can I sign a property sale or a lease electronically in South Africa?

The ECT Act doesn't validate an agreement for the alienation of immovable property, or a lease of immovable property in excess of 20 years, under the Alienation of Land Act (Schedule 2), so those follow that Act's own formalities. Leases of 20 years or less aren't on that list.

Are Attest signatures advanced electronic signatures?

No. They are electronic signatures under section 1 of the ECT Act; the advanced tier requires an accredited authentication product and face-to-face identification. Each Attest signature carries evidence aimed at section 15(3): the signer's own passkey signature over the document's fingerprint, a public blockchain anchor and a verifier anyone can run.
