On What Grounds Can You Contest a Will in South Africa?

A will in South Africa can be contested on four recognised legal grounds: lack of testamentary capacity at the time the will was made, undue influence by someone in a position of dominance over the testator, fraud or forgery (the testator was deceived or did not sign the document at all), and non-compliance with the Wills Act 7 of 1953’s formalities (the will was not in writing, signed, or attested by two competent witnesses as the Act requires). The contestation must in most cases be brought within three years of the date the Master of the High Court issues the letter of authority in the estate. It is launched either by way of a written objection lodged with the Master’s Office of the High Court in whose area the deceased was ordinarily resident, or — where the Master declines to act, or where the executor disputes the objection — by way of a High Court application under section 2(1)(b) of the Wills Act 7 of 1953, which gives the court jurisdiction to declare the validity, interpretation, or effect of a will. A potential contestant should gather the death certificate, the will itself, any prior will, and evidence relevant to the specific ground (medical records for capacity, witness statements for undue influence, handwriting evidence for fraud or forgery) before instructing an attorney.

The Legal Framework: How South African Law Treats a Will Contest

Will contests in South Africa are governed primarily by the Wills Act 7 of 1953, which sets out the formal-validity rules (including the formalities required for execution, set out in section 4A and the amendments regime in section 2), read together with the Administration of Estates Act 66 of 1965, which governs the Master’s Office process for winding up deceased estates. The substantive grounds for setting aside a will — capacity, volition (freedom from undue influence), knowledge and approval, and compliance with formalities — come from common law as codified and supplemented by the Wills Act.

It is important to distinguish a will contest from a maintenance claim against an estate. A will contest challenges the validity of the will itself on one of the grounds listed above. A maintenance claim is brought under section 3 of the Maintenance Act 99 of 1998 and section 2 of the Maintenance of Surviving Spouses Act 27 of 1990 by a surviving spouse or a child who was being maintained by the deceased, where the will (or intestate succession) fails to make adequate provision for their needs. The two routes run independently and may sometimes be pursued in parallel; an estate that survives a failed will contest may still give rise to a successful maintenance claim, and vice versa.

The Four Recognised Legal Grounds

A will can be set aside only on one of the four grounds recognised under South African succession law. Each ground requires its own evidentiary foundation, and the strength of the available evidence determines whether a contestation will succeed, settle, or fail.

1. Lack of Testamentary Capacity

The testator (the person who made the will) must have been capable of understanding the nature of making a will, the claims of those who might expect to benefit, and the extent of the estate being disposed of. These are the three classic capacity tests applied under South African common law.

Capacity is assessed as at the time the will was made, not at the time of death — a testator who was incapacitated for years could still have made a valid will during a lucid interval, and a testator whose faculties declined sharply after signing is not assisted by that fact if they were competent at execution. The evidentiary centre of gravity is usually contemporaneous medical records (diagnoses of dementia, delirium, or psychotic episodes), prescription records showing heavy sedation at the relevant time, and the surrounding circumstances (was the testator in hospital, in care, in an operating-theatre pre-medication bay, or recovering from a stroke at the time the will was signed?). A will made under a properly registered Power of Attorney is not automatically invalid; capacity remains the touchstone, not the document type.

2. Undue Influence

The challenger must show that the testator was coerced into making the will — or into particular bequests within it — by someone in a position of dominance over them. The dominant figure is typically a primary caregiver, a cohabiting partner, or a relative who was present at the will’s execution. The line between legitimate persuasion (encouraging, recommending, even strongly urging a particular bequest) and undue influence is whether the testator’s will was overborne — whether the testator’s mind has effectively become that of the influencer, so that the will reflects the influencer’s wishes rather than the testator’s own.

Evidence typically clusters around four indicators: the influencer’s presence at the will’s execution (or their role in arranging it), sudden exclusion of natural heirs who would ordinarily inherit, recent and unexplained changes of attorney and of witnesses, and the disproportionate benefit the influencer receives under the disputed will.

3. Fraud or Forgery

Fraud covers situations where the testator was deceived into signing — for example, being told the document was something other than a will (a power of attorney, an insurance form, a routine affidavit) — or where a bequest was inserted by deception after the will was signed. Forgery covers a will that the testator did not sign at all, where the signature is not the testator’s, or where one or both witnesses are not genuine. Forensic handwriting analysis (a registered forensic document examiner comparing the disputed signature against admitted specimens) and witness testimony about the execution are the usual evidentiary routes.

4. Non-Compliance with Wills Act Formalities

Under section 4A of the Wills Act 7 of 1953, read with the formalities in section 2, a valid will must be in writing, signed by the testator (or by someone else in the testator’s presence and by the testator’s direction), and attested by two competent witnesses who sign in the presence of the testator and in the presence of each other. A witness or the witness’s spouse who receives a benefit under the will is in principle disqualified from that benefit unless the court grants relief under section 4A(2).

A will that does not meet these formalities is not automatically void — the High Court has a dispensing power to validate a will in defined circumstances under section 2(3) — but the default position is invalidity. Common defect scenarios include one witness leaving the room before the other signed, the testator signing by mark without the required commissioner of oaths’ certification, a page substitution after execution, or only one competent and disinterested witness where section 4A would require two.

Common Sub-Situations Searchers Actually Face

Situation	Likely ground(s)	Practical consideration
Surviving spouse excluded	Capacity / undue influence	The survivor may also have a separate maintenance claim under the Maintenance of Surviving Spouses Act 27 of 1990, which is a different action from a will contest
Adult child excluded	Capacity / undue influence / improper execution	Children do not have an automatic right to inherit, so the contest is harder than it first appears
Child of the deceased excluded from a later will	Capacity / undue influence / revocation	Consider whether a prior valid will exists; the later will must stand on its own validity, but the prior will may still be operative if the later will is invalid
Second spouse’s family benefits at the expense of the first family	Capacity / undue influence / formalities	Medical and witness evidence becomes central
Will amended on the testator’s deathbed	Capacity / undue influence	Records from the treating doctor and attending nurse are pivotal
Will bears suspicious signatures	Fraud / forgery	Forensic examination and witness testimony on the execution

The Process, Step by Step

1. Obtain the documents. Obtain the death certificate and a copy of the disputed will from the Master’s Office of the High Court in whose area the deceased was ordinarily resident at death. For Gauteng-resident deceaseds, the Johannesburg Master’s Office (corner Sauer and Commissioner Streets, Marshalltown) handles estates of Johannesburg and surrounding areas, while the Pretoria Master’s Office (second floor, East Wing, Pretoria High Court, Paul Kruger Street) handles estates of Pretoria, Centurion, and northern/eastern Gauteng.
2. Identify the ground and gather evidence. Identify which of the four legal grounds applies, and gather the evidence relevant to that ground: medical records and prescription history for capacity; witness statements and evidence of presence at execution for undue influence; prior wills, handwriting samples, and witness testimony for fraud or forgery; the will itself and execution evidence for formalities.
3. Lodge an objection with the Master. Lodge a written objection with the Master within three years of the Master’s letter of authority being issued. The Master’s office will not validate the will over a properly lodged objection.
4. If unresolved, instruct an attorney for a High Court application. If the Master declines to act, or the executor disputes the objection, instruct an attorney to launch a High Court application under section 2(1)(b) of the Wills Act 7 of 1953, seeking an order declaring the will valid, invalid, or partially invalid.
5. Serve the respondents. Serve the application on the executor and on each beneficiary under the disputed will. They become respondents and have the right to oppose.
6. Affidavit evidence, or trial on oral evidence. The court hears the matter on affidavit evidence in motion court, or — where there is a genuine dispute of fact that cannot be resolved on the papers — on oral evidence at trial.
7. The court’s order. The court issues an order declaring the will valid, invalid in whole, or invalid in part. Partial invalidity is possible where only some clauses fail and the remainder can be sustained.

Time Limits and What Stops a Contest

The general three-year outer limit runs from the date the Master issues the letter of authority in the estate. Condonation for late filing is available only on good cause shown and is not routinely granted; the longer a contestant waits after acquiring knowledge of the disputed will, the harder it is to satisfy the court that condonation is warranted.

Two further bars are often overlooked. First, a person who, with full knowledge of the facts, has acted in a way consistent with the will being valid — for example, accepting a benefit under it, or assisting the executor in administering the estate without objection — may be barred from later challenging it. This is the “approbation and reprobation” line of cases: a litigant cannot approbate (accept the benefit of) a will and reprobate (seek to set aside) the same will at the same time. Second, the death of a potential witness does not by itself defeat the contest, but it does affect the weight of evidence available — contemporaneous medical records become correspondingly more important where witness memory is no longer reachable.

Costs and Prospects (What a Prospective Contester Should Know)

A contested estate action is generally more expensive than an uncontested winding-up, because the work runs on affidavit exchanges, expert evidence (medical or forensic), and opposed hearings. Fee ranges depend on the complexity of the file and on whether the matter settles before hearing. A clear-cut formalities defect that resolves on the papers is materially cheaper than a capacity challenge that requires expert medical evidence and a contested trial.

The general rule on costs — “costs follow the event” — means the losing party usually pays the winner’s legal costs. A contestant who fails on the merits can be ordered to pay the estate’s costs, and those costs are typically recovered from what the contestant would otherwise have received under the will or under intestate succession. Many contests settle before trial once the strength of the medical or witness evidence becomes clear. The practical question, in many files, is not “will I win” but “what does the evidence look like, and is a structured settlement with the executor and the beneficiaries possible at this stage?”

Contesting a will is squarely within the firm’s Wills & Estates and general litigation practices — Director Anna-Mi Nel, who heads the Family Law Department and co-directs the Sandton branch, has a reported specialisation in deceased estates and High Court litigation; the firm’s Roodepoort branch, under Director Nadine Roesch-Prinsloo, fields general litigation work that includes estate disputes. The combination means a client with grounds to suspect a will is invalid does not need to brief two firms: the same firm can review the Master’s file with one team and run the High Court application with the other.

Frequently Asked Questions

What are the four legal grounds to contest a will in South Africa?

The four recognised grounds are (1) lack of testamentary capacity at the time the will was made, (2) undue influence by someone in a position of dominance over the testator, (3) fraud or forgery (the testator was deceived or did not sign), and (4) non-compliance with the Wills Act 7 of 1953’s formalities (writing, signature, two-witness attestation). Each ground is treated separately in the case law and each requires its own evidentiary foundation.

How long do I have to contest a will after someone dies in South Africa?

The general rule is three years from the date the Master of the High Court issues the letter of authority in the estate. Outside that period a contest can only be brought with condonation from the High Court on good cause shown, which is not routinely granted. Acting promptly once grounds are suspected is therefore important.

Do children automatically inherit if they are excluded from a will?

No. South African law does not give children an automatic right to inherit. A child who has been excluded can only challenge the will if they can prove one of the four legal grounds (typically capacity or undue influence). A child who was being maintained by the deceased may, separately, have a maintenance claim against the estate under the Maintenance of Surviving Spouses Act 27 of 1990 or the Maintenance Act 99 of 1998 — that is a different action from a will contest.

Does a surviving spouse have more rights than children to contest a will?

A surviving spouse does not have stronger inheritance rights by default, but the spouse can claim maintenance from the estate under the Maintenance of Surviving Spouses Act 27 of 1990 if the will (or the intestate succession rules) fails to make adequate provision. This maintenance claim runs alongside — and is separate from — any contest on the four legal grounds.

Can I contest a will without a lawyer in South Africa?

A layperson may lodge a written objection with the Master’s Office, but once the matter escalates to a High Court application under section 2(1)(b) of the Wills Act 7 of 1953, the matter runs as motion-court litigation: affidavit founding papers, answering affidavits, replying affidavits, set-down, and (where facts are disputed) trial. Most contesting parties instruct an attorney for the High Court stage and brief counsel for the hearing.

Does the Master’s Office have the power to declare a will invalid?

The Master administers the estate and will not validate a will over a properly lodged objection, but the Master does not have the power to declare a will invalid. Only the High Court has that power under section 2(1)(b) of the Wills Act 7 of 1953. Where the Master declines to validate and the parties cannot agree, the dispute has to be referred to the High Court.

What evidence do I need to contest a will?

It depends on the ground. For capacity: contemporaneous medical records, prescription records, and statements from treating staff. For undue influence: evidence of who was present at execution, who suggested the bequests, and whether the testator’s will was overborne. For fraud or forgery: forensic handwriting analysis and witness testimony on the execution. For formalities: the will itself, and evidence of where and how it was signed and witnessed.

How much does it cost to contest a will in South Africa?

Costs depend on complexity. A clear-cut formalities defect that resolves on the papers is materially cheaper than a capacity challenge requiring expert medical evidence and opposed trial. As a rule, costs follow the event — a contestant who loses is usually ordered to pay the estate’s costs out of what they would otherwise have received.
