The short answer is that an electronically signed Offer to Purchase (OTP) for immovable property is not valid and is therefore not legally binding on the parties in South Africa.

The Legal Framework

Electronic signatures in South Africa are governed by the Electronic Communications and Transactions Act 25 of 2002 (“ECTA”). Section 4 of ECTA regulates the areas of law to which electronic signatures apply. Importantly, section 4(4) expressly excludes certain transactions from the ambit of ECTA, including agreements for the alienation of immovable property, which remain governed by the Alienation of Land Act 68 of 1981 (“AoLA”).

Section 2(1) of the AoLA provides that no sale of land will be of any force or effect unless it is contained in a written deed of alienation signed by the parties. The Act requires strict compliance with its formalities, and these statutory requirements cannot be satisfied by electronic means.

Case Law Confirmation

The legal position regarding electronic signatures and property transactions has been confirmed by the Johannesburg High Court in Aarifah Security Services CC v Jakoita Properties (Pty) Ltd and Others 2020 JOL 48794 (GJ).

At paragraph 63 of the judgment, the court held:

“A ‘normal’ signature, such as one finds at the foot of an email, whilst it might suffice for a formality requiring a signature laid down in contract, cannot suffice if the signature is required by statute. More fundamentally, however, sections 4(3) and 4(4) read with Schedules 1 and 2 of ECTA make it clear that its provisions can in any event not be employed to validate Deeds of Sale under the Alienation of Land Act.”

This judgment confirms that electronic signatures cannot be relied upon to validate an agreement of sale for immovable property.

Practical Implications

It is therefore clear that:

• An Offer to Purchase relating to immovable property must be in writing;
• It must be signed by all sellers and purchasers; and
• The signatures may not be electronic.

Failure to comply with these requirements will result in the agreement of sale being invalid and unenforceable, regardless of the intentions of the parties.

Conclusion

While electronic signatures are widely accepted in many contractual contexts, they cannot be used for agreements involving the sale of immovable property in South Africa. Parties are strongly advised to ensure that all statutory formalities are complied with to avoid disputes, delays, or the invalidation of a property transaction.
