Are electronic signatures legal in South Africa? The ECT Act, advanced signatures and property

South Africans e-sign all the time: lease agreements, employment contracts, loan documents, school forms. Most of the time that is perfectly valid. But South African law has one sharp edge that catches people out every year: an offer to purchase a house signed electronically may not be a valid sale.

The short answer

• The Electronic Communications and Transactions Act 25 of 2002 (ECTA) gives legal recognition to data messages (electronic documents) and electronic signatures.
• When the parties want a signature but have not agreed a type, any method that identifies the person and shows their approval, reliable enough for the purpose, will do. This covers most contracts.
• When a law requires a signature and does not say what type, only an advanced electronic signature (AES) satisfies it. An AES must be based on a product or service accredited by the South African Accreditation Authority.
• ECTA does not apply to agreements to sell land, long leases of land, wills and codicils, or bills of exchange. Those still need paper and ink.

The law: the ECT Act

ECTA follows the UNCITRAL model law. Its main rules:

• Information is not denied legal force just because it is in electronic form.
• Where a law requires a document to be in writing, a data message that is accessible for later use satisfies it.
• Data messages are admissible in evidence, and their weight depends on how reliably they were made, stored and communicated and how the originator was identified.

Section 13: two kinds of electronic signature

Section 13 creates two tiers:

An advanced electronic signature, once properly applied, is presumed valid. An ordinary electronic signature is not presumed valid in the same way, so if someone denies signing you must prove it, which is where an audit trail helps.

Who accredits advanced electronic signatures

Under ECTA, advanced electronic signatures must come from an authentication product or service accredited by the Accreditation Authority, now operated as the South African Accreditation Authority (SAAA) within the Department of Communications and Digital Technologies. The SAAA publishes the list of accredited products and services. Very few providers have been accredited, and an AES normally involves identifying the signer face to face before a certificate is issued. Check the SAAA's current list rather than relying on a vendor's marketing: an ordinary platform signature, however professional, is not an AES unless it runs on an accredited service.

What the courts have said

• Spring Forest Trading 599 CC v Wilberry (Pty) Ltd t/a Ecowash (Supreme Court of Appeal, 2014; reported as 2015 (2) SA 118 (SCA)). A contract had a clause saying it could only be changed or cancelled in writing signed by the parties. The court held that an exchange of emails with the parties' typed names at the end was enough. Because it was the parties, not a statute, that required the signature, section 13(3) applied and an advanced signature was not needed. The case confirms that typed names in emails can be signatures where the parties require one.
• Borcherds v Duxbury (Eastern Cape High Court, Port Elizabeth, 2020; reported as 2021 (1) SA 410 (ECP)). The buyers signed an offer to purchase a property in ink and emailed it. The seller opened it on his phone and signed and initialled it through DocuSign, then received a higher offer and tried to walk away from the first sale. The court held that by applying his signature through DocuSign with the intention of being bound, he had signed the deed of alienation as the Alienation of Land Act requires, and ordered him to honour the first sale. Commentators have criticised the judgment for not dealing with the ECTA exclusion discussed below. It is a single High Court judgment, and it has not changed the practice of conveyancers, who still insist on ink signatures for land sales.

Documents you cannot sign electronically (or need a special signature)

Section 4(3) and Schedule 1 switch off ECTA's writing and signature rules (and, for wills, most of its other rules on data messages) for certain Acts, and section 4(4) and Schedule 2 say ECTA must not be read as giving validity to four transactions. Together they exclude:

1. Agreements for the alienation (sale, exchange or donation) of land under the Alienation of Land Act 68 of 1981. Section 2(1) of that Act requires a written deed of alienation signed by the parties, and ECTA's writing and signature rules do not apply. Offers to purchase and sale agreements for property should be signed in ink.
2. Long-term leases of immovable property, described in Schedule 2 as leases "in excess of 20 years" under the Alienation of Land Act. Commentators have pointed out that the reference is muddled (the Alienation of Land Act does not deal with leases; the law on long leases is the Formalities in Respect of Leases of Land Act 18 of 1969, which deals with leases of 10 years or more), so treat any lease meant to be registered against the title deed as a paper-and-notary document.
3. Wills and codicils under the Wills Act 7 of 1953: executing, keeping and presenting them. A will must be on paper, signed and witnessed.
4. Bills of exchange (a cheque is a type of bill of exchange) under the Bills of Exchange Act 34 of 1964.

Schedule 1 also mentions the Stamp Duties Act 77 of 1968, which has since been repealed, so that item no longer has practical effect.

Where a statute requires a signature, you need an advanced electronic signature. Common examples are suretyships (which must be in writing and signed by the surety under the General Law Amendment Act 50 of 1956), and some documents under other laws. Where a notary, commissioner of oaths or witness is required, e-signing on your own does not satisfy the law.

Common situations

Employment contracts

The Basic Conditions of Employment Act requires employers to give written particulars of employment, but it does not require the contract to be signed in a particular way. Offer letters and employment contracts are routinely e-signed and are valid under section 13(3).

Residential leases

The Rental Housing Act 50 of 1999 requires a lease to be put in writing if the tenant asks, but it does not demand a particular kind of signature. A normal residential lease signed electronically is valid. The exception is a long lease (more than 10 years) that is meant to be registered against the title deed: registration needs a notarial lease executed before a notary, so that is still a paper process.

Buying or selling a house

Sign the offer to purchase and the deed of sale in ink, as explained above. Estate agents who send offers for electronic signature are taking a risk that the sale is void.

Transfers and the deeds office

The Electronic Deeds Registration Systems Act 19 of 2019 provides the legal basis for electronic lodgement and registration of deeds. The electronic system is being rolled out in stages, and for now your conveyancer will tell you what can be done electronically. None of this changes the rule that the underlying sale agreement must be signed.

Company documents

The Companies Act 71 of 2008 allows documents, notices and records to be in electronic form, and board and shareholder resolutions can be adopted by written consent, which can be given electronically. Documents that must be notarised or lodged in a specific format follow those rules.

How to get an advanced electronic signature in South Africa

An AES comes from an accredited provider listed by the SAAA. It usually starts with an in-person identity check, and the certificate is then held on a token, a card or in the provider's own signing platform. If the key is held on a token or inside the provider's platform, it cannot be used on a website that asks for a certificate file. Most people only need an AES for the relatively rare documents where a statute requires a signature.

Doing it with KovaPDF

• Leases, employment contracts, NDAs and service agreements: use Request Signatures. Each signer gets a private email link and signs in the browser without an account. Everyone receives the completed PDF with a certificate of completion (names, emails, open and sign times, IP address, browser), and the file is sealed with a trusted timestamp so any later change is visible. These are ordinary electronic signatures under section 13(3), not advanced electronic signatures.
• Signing on your own: Sign PDF adds a drawn, typed or uploaded signature image to a PDF.
• With a certificate: Digital Signature signs with your own .pfx or .p12 file. It only produces an advanced electronic signature if the certificate comes from an SAAA-accredited service and the key is exportable, which accredited services often do not allow.
• Checking a signature: Verify PDF Signature shows whether a digitally signed file has been changed.

Not for: offers to purchase land, deeds of sale, wills, long notarial leases or bills of exchange. See also can you e-sign a property deed or sale contract and can you sign a will electronically.
