What Clauses Are Essential To All Wills?

A valid South African will must satisfy the execution formalities in section 2 of the Wills Act 7 of 1953 — the testator signs at the end of the document in the presence of two competent witnesses, who sign in the testator’s presence and in the presence of each other — and must contain a defined set of essential clauses: identification of the testator, revocation of prior wills, appointment of an executor, identification of heirs and the share each is to receive, a residuary clause, a substitution clause, a survivorship clause, and a proper attestation block. Wills that omit any of these elements risk being interpreted against the testator’s wishes, falling into intestate succession under the Intestate Succession Act 81 of 1987, or being challenged on the grounds of ambiguity or invalid execution. The clauses below are the working minimum a properly drafted South African will contains; this article walks through each one, why it is essential, and what happens when it is missing.

The Statutory Framework: Wills Act 7 of 1953

The Wills Act 7 of 1953 governs the execution, interpretation, and revocation of wills in South Africa and applies uniformly across all provinces. Section 2 of the Act sets the formalities that make a will valid: the testator must sign the will at the end, in the presence of two or more competent witnesses, who in turn must sign in the presence of the testator and of each other. Section 2A was introduced to permit certain informal amendments made by the side of the end of a will under tightly limited conditions, but the safer practice remains the fresh execution of a new will whenever the testator’s wishes change materially. Section 2B of the Act, in turn, automatically treats bequests to a former spouse as revoked on divorce.

What happens after the testator dies is governed by the Administration of Estates Act 66 of 1965. The Master of the High Court for the province in which the deceased was ordinarily resident at death accepts the will, examines it for compliance with the Wills Act, formally appoints the executor named in the will (or appoints one where none is named), and supervises the winding-up of the estate. The Master’s Office also maintains a free safe-custody facility for original wills during the testator’s lifetime.

The Essential Clauses in a South African Will

Every well-drafted South African will contains the following clauses. Each is essential because its absence creates a specific, predictable failure mode in the administration of the estate.

1. Identification of the Testator

The will must state the testator’s full names, identity number, and an address. Without clear identification, the will can be challenged on identity grounds — a particular risk where two living people share a name or where the testator’s particulars on the will do not match those on the death certificate.

2. Revocation of Prior Wills and Codicils

An express clause revokes all earlier wills and codicils, so that the current document is the only operative testamentary instrument. Without this clause, an earlier will remains on foot to the extent it is not inconsistent with the new one, which is a common source of disputes where a testator updates their will informally.

3. Appointment of an Executor

The will names at least one executor to administer the deceased estate; the Master confirms the appointment and issues letters of executory. A “no appointment” clause is a frequent cause of delay and added cost because the Master must then select an executor under section 5 of the Administration of Estates Act 66 of 1965, with no input from the family.

4. Specific Bequests (Legacies)

Particular items or amounts left to named beneficiaries are recorded as specific legacies, each clearly identified. A general drafting rule is that the more specific the description, the less room there is for ambiguity later.

5. Identification of Heirs and Their Shares

The will states who inherits the residuary estate and in what proportions. A common drafting error is to leave a residual heir unstated, which forces intestate succession on the unallocated portion and distributes it under the Intestate Succession Act 81 of 1987 — not under the testator’s wishes.

6. Substitution Clause

The substitution clause names the person who inherits if a named heir predeceases the testator (typically outside the survivorship period). Without this clause, the predeceased heir’s share falls into intestacy rather than passing to the substitute the testator would have wanted.

7. Survivorship Clause

A survivorship clause typically requires heirs to survive the testator by a stated period — commonly 30 days. It prevents the estate from having to be administered twice in quick succession when two related deaths occur close together, which otherwise complicates accrual claims and exposes the estate to double estate duty.

8. Debt, Cost, and Tax Directions

The will states whether debts, funeral costs, and estate duty are to be paid from the residue or charged against a specific heir’s share, and identifies any assets bequeathed free of such charges. This single clause often determines whether an heir inherits a clean asset or a liability.

9. Power of Executor Clause

The executor clause grants the executor the powers needed to administer the estate: to sell, to invest, to distribute in specie, to sign documents, and to settle disputes. The Master’s standard form grants most of these powers automatically, but a tailored clause removes doubt and speeds up administration.

10. Testamentary Trust Clause

Where any beneficiary — typically a minor child or a person with special needs — is to inherit through a trust rather than directly, the will sets up the trust, names the trustees, states the vesting age, and defines the trustees’ powers. Without this clause, the executor would have to administer the inheritance on behalf of a minor, which is cumbersome and rarely in the testator’s long-term interest.

11. Guardianship Clause for Minor Children

Strictly not a “clause of the will” in the technical sense, but the appointment of a guardian for minor children is almost always inserted in the same document. The clause names the proposed guardian and expresses the testator’s wishes; the Master’s Court ultimately confirms the appointment, and the clause is persuasive rather than dispositive.

12. Attestation Clause

The attestation clause is the witness block: signature lines for the two witnesses, with a clear statement that the testator signed in their presence and they signed in the presence of the testator and of each other. This clause is the formal anchor of the will’s validity under section 2 of the Wills Act.

Clauses to Avoid or Use With Care

Some clauses that are common in foreign wills are either invalid or do not work in South African law as drafted. Practitioners should specifically watch for the following:

• Joint wills — two testators in a single document are not permitted under SA law and the will is invalid. Mirror wills, by contrast, are valid (two testators make substantially identical separate wills), but each testator must still execute independently.
• Marriage revocation — marriage (other than to an out-of-community spouse under an antenuptial contract with accrual) generally revokes a prior will; testators marrying after drafting a will must execute a new one, and the same applies to a civil union under the Civil Union Act.
• Divorce revocation — section 2B of the Wills Act automatically treats bequests to a former spouse as revoked on divorce, but a fresh will is still the safer route because section 2B revokes only the bequest, not the rest of the will.
• “No contest” or forfeiture clauses — these are generally not enforceable in SA in the same way as in US or UK practice, and should not be assumed to override a valid claim.
• Foreign-jurisdiction clauses — clauses drafted with reference to UK, US, or Australian practice often contain terminology (such as “testatrix,” “testimonium,” or “probate”) that either has no SA equivalent or carries a different meaning in SA law.

What Happens if Essential Clauses Are Missing

Each missing clause has a predictable consequence. The table below pairs the omission with the likely outcome:

Missing Clause	Likely Outcome
No executor appointed	Master appoints an executor under section 5 of the Administration of Estates Act 66 of 1965; the family has no say in the choice; delay and extra cost follow.
No residuary clause or unstated share	Unallocated residue falls into intestate succession and is distributed per the Intestate Succession Act 81 of 1987, not per the testator’s wishes.
No substitution clause	The share of a predeceased heir falls into intestacy rather than passing to the substitute the testator would have chosen.
No survivorship clause	Two deaths in quick succession force the estate to be wound up twice within a short period, complicating accrual claims and exposing the estate to double estate duty.
No proper attestation	The will is invalid under section 2 of the Wills Act; the estate falls entirely into intestacy regardless of how clearly the testator’s wishes are otherwise expressed.
No identification of heirs	The Master cannot determine beneficiaries; the estate may be administered as intestate until heirs are identified through family tracing.

Lodging the Will with the Master of the High Court

Every validly executed South African will is lodged with the Master of the High Court for the province in which the deceased was ordinarily resident at death (or, in the case of immovable property, where the property is registered) once the testator dies. The Master examines the will for compliance with the Wills Act 7 of 1953 formalities, formally appoints the executor named in the will, and issues letters of executory that authorise the executor to wind up the estate.

A copy of the will should also be held in safe custody during the testator’s lifetime — the Master’s Office maintains a safe-custody facility for this purpose at no charge, and many South African attorneys also keep original wills in their trust vaults. Practitioners almost always recommend that the testator’s nominated executor and at least one trusted family member know where the original will is stored; an original that cannot be found when it is needed may, in some cases, lead to a presumption of revocation and force the estate into intestacy.

Frequently Asked Questions

How many witnesses do you need for a valid will in South Africa?

Two competent witnesses who sign in the presence of the testator and in the presence of each other. Section 2 of the Wills Act 7 of 1953 makes these formalities mandatory — a will with only one witness, or where the witnesses did not sign in each other’s presence, is invalid regardless of how clearly the testator’s wishes are otherwise expressed.

Does a South African will have to be notarised or witnessed by a lawyer?

No. Section 2 of the Wills Act 7 of 1953 requires only two competent witnesses and the testator’s signature at the end of the document. A notary, attorney, or other official is not a requirement of validity, although practitioners strongly recommend drafting through an attorney because poorly-drafted clauses cause much of the litigation the formalities exist to prevent. Burger Huyser Attorneys’ Wills & Estates practice drafts wills across all Gauteng branches so that each clause is anchored to the testator’s specific circumstances rather than to a generic template.

What happens if my will does not name an executor?

The Master of the High Court will appoint an executor under section 5 of the Administration of Estates Act 66 of 1965, and the testator’s family will have no say in the choice. This almost always delays the winding-up of the estate and adds cost, which is why the appointment of an executor is treated as an essential clause rather than optional.

Does getting married cancel my existing will in South Africa?

Generally yes — entering into a marriage other than out of community of property under an antenuptial contract with the accrual system operates to revoke an earlier will. The same applies to a civil union under the Civil Union Act. A testator who marries after signing a will should execute a fresh one as soon as reasonably possible.

Does divorce cancel bequests to my former spouse in my will?

Section 2B of the Wills Act 7 of 1953 automatically treats bequests to a former spouse as revoked on divorce, as if the spouse had died on the day the divorce was granted. However, executing a fresh will after the divorce is still recommended — section 2B revokes only the bequest, not the rest of the will, and the surviving clauses may not reflect the testator’s changed intentions.

Can I write my own will without a lawyer in South Africa?

Yes — the law does not require a lawyer, and a hand-written will is valid provided the Wills Act 7 of 1953 formalities (testator’s signature at the end, two competent witnesses signing in the testator’s presence and in each other’s presence) are met. Practitioners strongly recommend using an attorney nonetheless, because missing essential clauses (executor appointment, substitution clause, residuary clause) are the typical reason hand-written wills end up in litigation or intestacy despite being validly signed.

A valid South African will that includes all essential clauses — revocation, executor appointment, identification of heirs, residuary and substitution clauses, survivorship period, and a properly witnessed attestation block — is the single most effective step a testator can take to protect their family.
