Which Documents Cannot Be Signed Electronically in South Africa?

Four things. Under Schedule 2 of the Electronic Communications and Transactions Act 25 of 2002, an electronic signature cannot validly execute the sale of immovable property, a long-term lease of property in excess of 20 years, a will or codicil, and a bill of exchange such as a cheque. Everything else your business signs can be signed electronically.

This is general information to help you understand the law, not legal advice. For a specific document or dispute, check with an attorney.

The four exclusions, straight from the Act

The list is short, closed, and has not changed since the Act commenced. Schedule 2 of ECTA, read with section 4(4), names exactly these four:

Excluded transaction	Governed by	Everyday example
Agreement for the alienation of immovable property	Alienation of Land Act 68 of 1981	An offer to purchase or deed of sale for a house or land
Long-term lease of immovable property in excess of 20 years	Alienation of Land Act 68 of 1981	A 25 year ground lease
Execution, retention and presentation of a will or codicil	Wills Act 7 of 1953	Your last will and testament
Execution of a bill of exchange	Bills of Exchange Act 34 of 1964	A cheque

You can read the wording yourself in the official text of the Act. If the document in front of you is not on that list, ECTA lets you sign it electronically. That is the whole test, and it is narrower than most people assume.

The detail most guides get wrong

Two things worth getting right, because plenty of published summaries do not.

The lease threshold is 20 years, not 10. You will see "ten years or longer" repeated on a surprising number of South African pages. Schedule 2 says "in excess of 20 years". The 10 year figure belongs to a different statute dealing with lease formalities, and it has been quietly copied across into e-signature guides where it does not belong. If you are signing a 15 year lease, the ECTA exclusion does not touch you.

ECTA does not "ban" these signatures. This sounds like hair-splitting; it is not. Section 4(4) says the Act "must not be construed as giving validity to any transaction mentioned in Schedule 2". ECTA does not prohibit you from applying an electronic signature to a deed of sale. It simply declines to lend its validity to it, which throws you back on the formalities in the underlying statute, and those are what decide whether your document stands. That is why the property question has been argued in court rather than settled by the Act alone.

Has a court ever accepted an electronic signature on a property sale?

Once, on narrow facts, and it is not the green light it gets quoted as. In Borcherds and Another v Duxbury and Others (judgment 22 September 2020, Eastern Cape High Court), a seller used DocuSign to apply an image of his own wet-ink signature to a sale agreement. The court held he had signed as the Alienation of Land Act requires, because it was still his actual signature and not a computer-generated mark intended to stand in for one.

Read the limits carefully before you rely on it. It is a single High Court judgment, not binding on other divisions, and it has not been confirmed by the Supreme Court of Appeal. It turned on a digitised copy of a real handwritten signature, not on a typed name or a click-to-sign box. The practical position for a South African business in 2026 is unchanged: wet ink on the property sale, and keep the innovation for the other 95% of your paperwork.

What you can sign electronically, and which type you need

Nearly everything else, but the type of signature matters. Section 13(1) of ECTA draws a line that catches people out:

• Where a law requires a signature and does not say what kind, only an advanced electronic signature will do. That is an accredited signature tied to a verified identity, not any e-signature tool.
• Where the parties themselves require a signature, an ordinary electronic signature is enough. In Spring Forest Trading v Wilberry (judgment 21 November 2014), the Supreme Court of Appeal accepted typed names at the foot of emails as valid signatures to cancel an agreement, because the parties had set that formality themselves.

So your service agreements, quotes, NDAs, employment contracts, engagement letters, and the ordinary run of commercial paperwork are all fair game for electronic signing. Suretyships and anything where a statute demands a signature without specifying the type are where you reach for the advanced electronic signature.

A practical checklist before you send anything for signature

1. Is it on the list of four? Property sale, lease over 20 years, will, bill of exchange. If yes, print it and sign it in ink.
2. Does a law require the signature? If yes and the law is silent on type, use an advanced electronic signature.
3. Is it just the parties requiring it? An ordinary electronic signature is enough.
4. Can you prove who signed and that nothing changed after? Keep the audit trail. This is what gets tested if the signature is ever challenged.

If you work in property, where this list bites hardest, the 2026 playbook for estate agents covers what can and cannot be automated around the deal.

Frequently Asked Questions

Can a will be signed electronically in South Africa?
No. The execution, retention and presentation of a will or codicil under the Wills Act 7 of 1953 is excluded by Schedule 2 of ECTA. A will must be signed by hand in the presence of two competent witnesses. An electronically signed will risks being invalid.

Can I sign an offer to purchase electronically?
Not safely. An agreement for the alienation of immovable property is excluded under Schedule 2. One High Court judgment accepted a digitised image of a real handwritten signature applied via DocuSign, but it is not binding nationally and has not been confirmed on appeal. Use wet ink.

Is a lease of 10 years excluded from electronic signature?
No. Schedule 2 only excludes a long-term lease of immovable property in excess of 20 years. A 10 year or 15 year lease can be signed electronically. The widely repeated "10 year" figure comes from a different statute and does not apply to the ECTA exclusion.

What is the difference between an ordinary and an advanced electronic signature?
An ordinary electronic signature is any data intended to serve as a signature, such as a typed name. An advanced electronic signature is accredited and tied to a verified identity. Section 13(1) of ECTA requires the advanced type wherever a law demands a signature without specifying which kind.

Does ECTA make electronic signatures illegal for these four documents?
Not exactly. Section 4(4) says the Act must not be construed as giving validity to those transactions. It does not prohibit the signature; it withholds ECTA's validity, which leaves the formalities of the underlying law to decide. In practice the result is the same: sign those four by hand.

Take the paperwork drag out of your week

The list of things you cannot sign electronically is four items long. The list of things you can is everything else, and most South African businesses are still printing, scanning and chasing all of it. NexSign handles the signing and the audit trail on the paperwork that is allowed to move, so the only thing that needs ink is the deed of sale. Not sure which of your documents are stuck for a good reason and which are stuck out of habit? A Business Autopsy maps where the paperwork actually jams, or book a discovery call to talk it through.
