TL;DR: In South Africa, a Will must be signed by the testator on every page and witnessed by two competent witnesses aged 14+. A witness must make a sworn statement which shows they observed the correct execution of the document. While not legally required, it significantly simplifies the probate process. The Wills Act 7 of 1953 sets out all signing requirements.

What Are the Signing Requirements for a Will in South Africa?
The legal validity of your Will depends on proper execution of signatures and witness documentation according to South African law. The Wills Act 7 of 1953 establishes specific rules which must be followed during execution to prevent your Will from becoming void. An Affidavit of Execution, while optional, provides additional legal protection by confirming the signing process was followed correctly.
- The Wills Act 7 of 1953 establishes these requirements which a Will must follow to obtain legal validity:
- The document requires physical presence to exist in written form through either handwriting or typed or printed text.
- The testator needs to sign or initial every page which appears in the document.
- Two witnesses who have reached the age of 14 need to sign the document while being present.
- Both witnesses need to observe each other simultaneously during their moment of witness.
- Any person aged 14 or older who is competent to give evidence in court can be a witness. Critical rule: a witness must not be a beneficiary of the Will. A beneficiary who signs as a witness will lose their right to receive any inheritance according to that specific Will. The witness’s spouse or civil union partner is also disqualified from benefiting.
Who Can Be a Witness to a Will in South Africa?
One of the Will witnesses must swear an Affidavit of Execution which confirms they properly signed and witnessed the Will document. The witness needs to swear before a Commissioner of Oaths that:

What Is an Affidavit of Execution?
Both witnesses signed in each other’s presence and in the presence of the testator
- The testator appeared to be of sound mind and not under duress
- No. An Affidavit of Execution is not required for a Will to be valid in South Africa. However, it is highly recommended because it provides evidence that the signing requirements were met. The Master of the High Court will need to verify correct document execution during probate when this document does not exist which leads to longer waiting periods.
- The Will remains unsigned because I failed to place my signature or initials on every page.
Is an Affidavit of Execution Legally Required?
The document fails to include two witnesses because we only obtained one signature.

Common Signing Mistakes to Avoid
- The witnesses failed to sign the document at the same time and they also did not sign in the same location.
- The process allows a beneficiary to act as a witness.
- The law does not permit witnesses who are younger than 14 years old to participate in this matter.
- All parties need to sign documents together when they should be present for each other’s signatures.
- No. Currently, South African law requires a physical (wet ink) signature on a printed Will. Electronic signatures do not support Will acceptance.
- No. Wills do not need notarization to become valid documents according to South African law. Proper signing and witnessing is sufficient.
