Disputing a Will? | Challenging the Validity of a Will in South Africa

A will can be challenged in South Africa on a closed set of grounds under the Wills Act 7 of 1953 and the common law — most commonly lack of testamentary capacity (section 4), undue influence, fraud or forgery, duress, or non-observance of the Act’s formalities (sections 5 and 6). The challenge is launched by lodging a caveat at the Master’s Office for the region in which the deceased was ordinarily resident (or held immovable property), which prevents the Master from issuing letters of executorship until the caveator’s objection is dealt with. Beneficiaries named in an earlier valid will and intestate heirs under the Intestate Succession Act 81 of 1987 have standing to challenge, the disputed will is presumed valid until the challenger proves the ground on the balance of probabilities, and costs follow the result.

The Legal Framework: When a Will Can Be Challenged

The substantive law on testamentary capacity and the validity of wills sits in the Wills Act 7 of 1953 (as amended), read with the South African common-law grounds of undue influence, fraud, duress, and mistake. The Act prescribes both the formalities a will must satisfy (sections 5 and 6) and the capacity test for the testator (section 4), while the common-law grounds fill the gaps the statute does not expressly cover.

A properly executed will is taken to reflect the deceased’s free and informed intention. The challenger therefore bears the onus of rebutting the presumption of validity — simply disagreeing with how the estate was divided is not a ground. Only parties with sufficient legal standing may bring a challenge (covered below), and a successful challenge may lead to the will being set aside in whole or in part, to the will being rectified by the court, or to an earlier valid will being substituted.

Burger Huyser Attorneys’ Wills & Estates practice is built around these mechanics. Caveat work, family-mediation support, and Master’s Office submissions sit within the practice under Managing Director Marni Huyser, supported by the firm’s Deceased Estate Administrator.

Who Has Standing to Challenge a Will

Standing is a threshold issue — a challenge brought by the wrong party is open to being struck off the roll with costs. The categories that typically have a sufficient legal interest are:

• Beneficiaries named in an earlier valid will — if the deceased made a prior will that the challenger argues is the true “final” testament, the prior-will beneficiaries have a direct interest in supporting the challenge.
• Intestate heirs — persons who would inherit under the Intestate Succession Act 81 of 1987 if no valid will existed have standing, because the relief they seek (a finding that the disputed will is invalid) is what would shift the estate onto the intestate track in their favour.
• The surviving spouse — a surviving spouse generally has standing regardless of whether they would also inherit as an intestate heir, given the overlay of matrimonial property law (community of property, accrual, or antenuptial contract).
• The Master of the High Court — the Master may intervene on the public-interest side where the formalities are clearly breached.
• Third parties (no standing) — creditors and other third parties generally lack standing to dispute a will’s validity; their recourse lies against the estate once administration is under way.

The Recognised Grounds for Challenging a Will

The grounds on which a will may be impugned are closed. The principal grounds, the source for each, and what the challenger must show, are set out in the table below.

Ground	Source	What the challenger must show
Lack of testamentary capacity	Wills Act 7 of 1953 s 4; common law	At the time of execution, the deceased did not have the mental ability to understand the nature and effect of the will, the assets being disposed of, or the claims of those who might expect to benefit.
Undue influence	Common law	Someone improperly coerced the deceased’s mind; the pressure was so serious the deceased would not have made the same dispositions but for the influence.
Fraud or forgery	Common law	The will was not in fact the deceased’s act — for example, substituted pages, a forged signature, or material misdescription of contents at signing.
Duress or fear	Common law	Threats (usually of serious harm to the deceased or a near-one) drove the deceased’s testamentary dispositions.
Non-observance of formalities	Wills Act 7 of 1953 ss 5, 6, 13	Will not signed in the manner required, not attested by two competent witnesses present at the same time, or marks not properly attested.
Mistake / rectification	Common law	The will does not reflect the deceased’s actual intention in a way the court can correct without rewriting the document.
Revocation	Wills Act 7 of 1953 ss 4A, 5A	A subsequent marriage (subject to a contrary-intention provision in the will), dissolution of an out-of-community marriage with accrual, or destruction of the will with intention to revoke.

A challenge need not pick one ground only — pleadings will typically plead more than one in the alternative where the available evidence is consistent with several. Lack of capacity and undue influence together account for the bulk of contested estates in reported High Court decisions. Non-observance of formalities is the cleanest ground where a witness signature is missing or the testator did not sign in front of both witnesses; the will is void, not merely voidable.

Step-by-Step: How to Dispute a Will in South Africa

The dispute process has a fixed order. Each step is set out below.

1. Confirm standing — establish that you fall into one of the standing categories above (earlier-will beneficiary, intestate heir, surviving spouse); obtain a family-tree and prior-will audit before going further.
2. Investigate the basis — gather evidence relevant to the ground: medical and pharmacy records on capacity, contemporaneous notes on the deceased’s mental state, communication records around the time of execution, drafts and witness accounts, and any record of relationship dynamics relevant to undue influence.
3. Obtain a copy of the will from the Master — once the estate file is open, a copy of the lodged will is generally available on request from the Master’s Office.
4. Lodge a Master’s Office caveat — lodge the caveat in the prescribed form at the Master’s Office for the region in which the deceased was ordinarily resident or held immovable property; the caveat pauses the issue of letters of executorship until the caveator’s objection is resolved.
5. Consider family mediation or negotiation — many will challenges settle at this stage; a properly mediated settlement, once reduced to a court order, has the same force as a judgment on the merits.
6. Issue a High Court application — where the caveat is not resolved, the challenge is brought in the division of the High Court with jurisdiction (typically where the deceased was ordinarily resident, or — where the relief sought targets immovable property — where the property is registered).
7. Plead, exchange discovery, and lead evidence — formally plead the ground(s); exchange discovery; lead oral evidence, including expert psychiatric evidence where capacity is in issue.
8. Obtain the order and finalise the estate — the court may set aside the will in whole or in part, order rectification, or substitute an earlier valid will; the executor then administers the estate on the basis of the order.

Where the matter tips into a contested motion-court application, the file typically moves into the firm’s General Litigation practice (Director Nadine Roesch-Prinsloo, Roodepoort branch) and runs alongside the Wills & Estates work already on foot.

Time Limits: How Long You Have to Challenge

There is no single short statutory deadline that extinguishes the right to challenge a will — there is no equivalent of a three-year prescriptive bar for this category of dispute. The Prescription Act 68 of 1969 extinguishes ordinary debt claims by lapse of time but does not bar a will-validity challenge in the same way, because the matter is one of substantive validity, not a money claim.

The practical urgency sits with the Master’s Office caveat. Once the Master issues letters of executorship and the executor administers and distributes the estate, recovery is materially harder — even if a later challenge succeeds. Delay is also a credibility factor the courts take into account when assessing the merits, the risk of prejudice to other heirs, and the integrity of distributions already made. Where the challenge is raised years later, the explanation for the delay should be set out in the founding affidavit at the outset rather than buried in replying affidavit evidence.

The Master’s Office and the High Court: Where Each Sits in the Process

Two distinct forums do the work — the Master’s Office for the procedural-administration layer, and the High Court for the substantive dispute.

• Master’s Office (Department of Justice and Constitutional Development) — administers estates, holds the original will, and may refuse to issue letters of executorship while a caveat is in force. The relevant Master is the Master of the High Court for the region in which the deceased was ordinarily resident or held immovable property.
• Master’s filing layer — typical actions include lodging the caveat, requesting a copy of the will, opposing the appointment of the nominated executor, and (on resolution) issuing the letters of executorship in line with the court’s order or settlement.
• High Court — the division with jurisdiction is typically the one in whose area of jurisdiction the deceased was ordinarily resident at death (or, where the relief targets immovable property specifically, where the property is registered).
• Procedure in the High Court — challenges usually proceed on application (motion court) supported by founding affidavits, with the disputed will and the medical/expert record annexed; contested challenges are usually referred to trial, with oral evidence.
• Practice directives vary by division — the Gauteng Local Division (Pretoria and Johannesburg seats) has its own practice directives and Rules of Court. Practitioners should check the relevant division’s rules for any pre-trial alternative-dispute-resolution step.

The Remedy: What an Order Setting Aside or Rectifying a Will Does

The court’s order determines what happens to the estate. The available outcomes, in ascending order of scope, are:

• Will set aside in full — the estate is administered as if the deceased died intestate under the Intestate Succession Act 81 of 1987, with the estate distributed to the intestate heirs in the order set out in that Act.
• Will set aside in part — only the offensive clauses are removed; the valid parts of the will stand and govern the remainder of the estate.
• Rectification ordered — the will is read as the deceased intended it to read; a narrow remedy granted only where the court is satisfied of the deceased’s actual intended wording.
• Earlier valid will substituted — the earlier will governs the estate in place of the disputed will.
• Executor’s exposure — an executor who has administered and distributed the estate in the face of a properly lodged caveat may face personal liability to the caveator for distributions made in disregard of the caveat.

Practical Cost and Risk Considerations

Cost and risk considerations should drive the decision to challenge (or defend) before the substantive merits are reached.

• Costs follow the result — an unsuccessful challenger generally pays a portion of the other side’s costs; a successful challenger recovers costs from the estate.
• Investigation costs — gathering psychiatric records, tracing drafts, and commissioning expert evidence can be substantial before any application is filed; these costs are not always fully recoverable even where the challenge succeeds.
• Settlement is common — most contested estates settle before trial, particularly where there is a clear family-relationship driver (a remarriage, an estrangement, a perceived disinheritance); a properly reduced settlement order is binding.
• Adverse-costs risk on weak challenges — a poorly formulated challenge, or one raised without proper standing, can attract adverse-costs orders, particularly where the executor is forced to defend the Master’s process.
• Tax consequences — where the challenge succeeds and the estate falls into intestacy, the estate duty calculation changes; the estate’s tax practitioner should re-run the calculation on the basis of the court order.

Frequently Asked Questions

Can you dispute a will in South Africa?

Yes — a will can be disputed on a closed set of grounds: lack of testamentary capacity under section 4 of the Wills Act 7 of 1953, undue influence, fraud or forgery, duress, non-observance of the Act’s formalities, revocation (in some cases), and a narrow set of common-law grounds such as mistake. The challenger must prove the chosen ground on the balance of probabilities, and must have standing — typically as an earlier-will beneficiary or an intestate heir under the Intestate Succession Act 81 of 1987.

How long do you have to contest a will?

There is no single short statutory deadline that extinguishes the right to challenge a will. The Prescription Act 68 of 1969 does not bar a will-validity challenge in the way it bars an ordinary debt claim. The practical urgency is to lodge a Master’s Office caveat before the Master issues letters of executorship and the estate is administered — once assets have vested in the nominated beneficiaries, recovery is far harder even if a later challenge succeeds. Delay is also a credibility factor the court considers on the merits.

Who can challenge a will?

Standing is restricted to parties with a sufficient legal interest. In practice that means beneficiaries named in an earlier valid will and intestate heirs under the Intestate Succession Act 81 of 1987, plus the surviving spouse (with the overlay of matrimonial property law). The Master of the High Court can intervene in limited cases where formalities are clearly not observed. Creditors and other third parties generally do not have standing to dispute a will’s validity.

What are the most common grounds for contesting a will?

Testamentary capacity (the deceased did not have the mental ability to understand the nature and effect of the will at the time of execution) and undue influence (someone improperly coerced the deceased’s mind at the relevant time) account for most contested estates in reported decisions. Where any of the formalities in section 5 of the Wills Act 7 of 1953 — signature by the testator in the presence of two competent witnesses who also sign in the testator’s presence — is breached, the will is invalid for non-observance of formalities.

Do I need a lawyer to challenge a will?

A caveator can lodge a Master’s Office caveat personally and represent themselves in court, but disputes over testamentary capacity (which turn on psychiatric and medical evidence) and undue influence (which is factually contested) are almost always run through attorneys and counsel. Wrongly pleaded challenges or challenges by parties without standing can attract substantial adverse-costs orders, and a properly evidenced challenge requires drafting and evidentiary discipline of the kind typical of motion-court litigation.

What happens to the estate while the will dispute is ongoing?

A caveat properly lodged at the Master’s Office prevents the Master from issuing letters of executorship to the nominated executor until the caveator’s objection is resolved. Where the Master issues letters despite an existing caveat, the executor’s subsequent distributions are at personal risk. Most disputes are resolved (by mediation or negotiation) before formal litigation; only the unresolved minority reach a contested High Court hearing.
