What Makes a Will Valid in South Africa, and Who Must Not Witness It

The most expensive mistake in South African estate planning is not choosing the wrong heir. It is asking the wrong person to sign as a witness.

Section 4A of the Wills Act 7 of 1953 disqualifies that person from inheriting anything under the will — and disqualifies their spouse too. It is a single sentence, it is absolute unless one of three exceptions applies, and it routinely destroys the intention of a perfectly sensible document because the testator asked the two people standing nearest to them.

Those two people are usually family.

The five formalities

Section 2(1)(a) of the Wills Act sets out what makes a will validly executed. All five must be satisfied.

(i) "the will is signed at the end thereof by the testator or by some other person in his presence and by his direction"

(ii) "such signature is made by the testator or by such other person or is acknowledged by the testator and, if made by such other person, also by such other person, in the presence of two or more competent witnesses present at the same time"

(iii) "such witnesses attest and sign the will in the presence of the testator and of each other, and, if the will is signed by such other person, in the presence also of such other person"

(iv) "if the will consists of more than one page, each page other than the page on which it ends, is also so signed by the testator or by such other person anywhere on the page"

(v) "if the will is signed by the testator by the making of a mark or by some other person in the presence and by the direction of the testator, a commissioner of oaths certifies that he has satisfied himself as to the identity of the testator and that the will so signed is the will of the testator, and each page of the will, excluding the page on which his certificate appears, is also signed, anywhere on the page, by the commissioner of oaths who so certifies"

Four of those five fail in ordinary households for ordinary reasons.

Signed at the end. Not initialled somewhere near the bottom, not signed on the first page. At the end of the will.

Both witnesses present at the same time. The commonest execution failure in practice is the relay: the testator signs, one neighbour signs in the morning, the other signs that evening. Sub-paragraph (ii) requires two or more competent witnesses present at the same time, and (iii) requires them to sign in the presence of the testator and of each other. A will witnessed in sequence has not been executed in compliance with section 2.

Every page signed. Sub-paragraph (iv) requires the testator to sign every page except the last, anywhere on that page. An unsigned page 2 in a four-page will is a defect.

A mark or a proxy signature brings in a commissioner of oaths. If the testator cannot write and signs with a mark, or directs someone else to sign for them, a commissioner of oaths must certify identity and that the document is the testator's will, and must sign every page except the one carrying the certificate. This is the route for a frail or illiterate testator and it is frequently done wrong — usually by omitting the certificate altogether.

Who counts as a competent witness

Section 1 defines it narrowly and usefully:

"a person of the age of fourteen years or over who at the time he witnesses a will is not incompetent to give evidence in a court of law"

Fourteen is the floor. Note what the definition does not say: it does not exclude a beneficiary. A beneficiary is a perfectly competent witness. The will remains valid. The beneficiary simply loses the inheritance — which is a much crueller outcome, and it is section 4A that does it.

Section 4A: the provision that disinherits

4A(1) "Any person who attests and signs a will as a witness, or who signs a will in the presence and by direction of the testator, or who writes out the will or any part thereof in his own handwriting, and the person who is the spouse of such person at the time of the execution of the will, shall be disqualified from receiving any benefit from that will."

Three categories of person are caught, and in each case their spouse goes down with them:

The witnesses. The well-known one.
Anyone who signs on the testator's behalf, in their presence and by their direction.
Anyone who writes out the will, or any part of it, in their own handwriting.

That third limb is the one nobody sees coming. A wife who handwrites her husband's will — a common thing in households where a lawyer is unaffordable — has disqualified herself from benefiting under it. So has an adult son who writes out a few clauses for an elderly parent.

And the spousal extension doubles the blast radius. Asking your son-in-law to witness disqualifies your daughter.

The three exceptions

Section 4A(2) provides three ways out, and they are uneven.

(a) A court declaration. A court may declare the person competent to receive the benefit "if the court is satisfied that that person or his spouse did not defraud or unduly influence the testator." A real remedy — and a High Court application, paid for out of an estate the family is already waiting on.

(b) The intestate-share cap. A disqualified person who would have inherited under intestate succession anyway may still receive a benefit, but "the value of the benefit which the person concerned or his spouse receives, shall not exceed the value of the share to which that person or his spouse would have been entitled in terms of the law relating to intestate succession."

This is the quiet partial rescue, and it explains why the mistake is often invisible until it matters. A spouse or child who witnesses the will does not usually lose everything — they are capped at what they would have received had there been no will at all. Which is precisely the outcome the will existed to change. Someone who was left the house instead of an equal share gets the equal share. See our guide to intestate succession for what that share actually looks like.

(c) Two other clean witnesses. A witness is not disqualified if "the will concerned has been attested and signed by at least two other competent witnesses who will not receive any benefit from the will concerned."

Read that carefully, because it is the practical fix: the Act requires two witnesses, but nothing stops you having four. If two disinterested witnesses sign, a third who happens to be a beneficiary is protected by 4A(2)(c).

That said, the better answer is simply not to use beneficiaries as witnesses at all.

If it goes wrong: section 2(3)

Section 2(3) is a genuine safety net, and it is stronger than people expect:

"If a court is satisfied that a document or the amendment of a document drafted or executed by a person who has died since the drafting or execution thereof, was intended to be his will or an amendment of his will, the court shall order the Master to accept that document … as a will, although it does not comply with all the formalities for the execution or amendment of wills referred to in subsection (1)."

Note "shall", not "may". Where the court is satisfied on intention, it must order acceptance.

Two things temper that.

It is a court application. Somebody must brief an attorney, launch proceedings in the High Court, and prove the deceased's intention — usually against a family member who prefers the intestate outcome. The estate is frozen while it runs.

The test is intention, and intention has to be proved by evidence. A draft on a laptop with no signature and no date is a much harder case than a signed will missing an initial on page three.

Section 2(3) is the reason a defective will is not automatically worthless. It is not a reason to be casual about the formalities, because the cure costs more than the disease would have.

Getting it right in one sitting

Print the whole will. Do not sign a document that has been amended by hand unless the amendment itself complies with the Act's formalities for amendments.
Get two witnesses who inherit nothing, and whose spouses inherit nothing. Neighbours, colleagues, the person at the pharmacy counter. Not your children, not your beneficiaries' spouses, not the person who typed it.
Everyone in the same room at the same time. Testator signs at the end; both witnesses watch; both witnesses then sign in front of the testator and in front of each other. No relay.
Sign every page. Testator signs each page except the last, anywhere on it. Have the witnesses do the same — the Act does not require it of them on every page, but it removes an argument.
If a mark or a proxy signature is involved, get a commissioner of oaths, get the certificate, and have the commissioner sign every page except the certificate page.
Keep the original safe and tell someone where it is. The Master administers the original. A photocopy sends the family to court.

Once it is signed, the will decides what happens; how much the estate pays to be wound up is a separate matter, covered in our guides to executor fees and winding up a deceased estate. What the estate owes SARS is covered in estate duty and inheritance tax.

Frequently asked

Can my wife witness my will? She may — she is a competent witness and the will stays valid — but section 4A(1) then disqualifies her from receiving any benefit under it, subject to the exceptions. Do not do it.

My son witnessed my will. Does he lose everything? Not necessarily. Section 4A(2)(b) lets a disqualified person who would have inherited on intestacy still receive a benefit, capped at the value of their intestate share. If the will left him more than that share, the excess is lost.

I wrote my husband's will out by hand. Does that affect me? Yes. Section 4A(1) disqualifies "any person who writes out the will or any part thereof in his own handwriting", and their spouse. Writing it out is treated the same as witnessing it.

How many witnesses do I need? Two competent witnesses, present at the same time. There is no bar on having more, and section 4A(2)(c) protects a beneficiary-witness where at least two other competent witnesses who take no benefit have also signed.

How old must a witness be? Fourteen or over, and not incompetent to give evidence in a court of law.

Do I have to sign every page? Yes — every page other than the one on which the will ends, anywhere on the page, under section 2(1)(a)(iv).

My father's will is missing a signature on one page. Is it void? It does not comply with section 2(1), but section 2(3) allows a court to order the Master to accept a document it is satisfied was intended to be the will. That requires an application, so take legal advice promptly rather than assuming either outcome.

Does a will have to be typed or drafted by a lawyer? Neither is required by the Act. But if someone handwrites it, section 4A(1) disqualifies that person and their spouse from benefiting — which is why a handwritten will drafted by a family member so often defeats itself.
