Contesting a Will in Singapore

Most people who say they intend to contest a will mean one of two entirely different things, and the distinction decides everything that follows. Some mean that the document is not a valid will at all — that the deceased did not know what he was signing, or was pressed into signing it, or that the signature is not his. Others mean that the will is perfectly valid and profoundly unfair, and that the court should redistribute the estate.

Singapore law treats those as separate exercises, with separate grounds, separate procedures and, importantly, separate prospects. A challenge to validity is a probate action and it succeeds only on proof of something specific having gone wrong. A claim for provision out of the estate is a statutory application available to a defined and comparatively narrow class of dependants. Confusing the two is the commonest error in this field, and it is usually an expensive one.

What follows is a map of both: the grounds on which a Singapore will can be set aside, the evidence each requires, the procedure that preserves your position while you investigate, and the very different regime that applies to Muslim estates.

Challenging the validity of the will

Formal validity

The starting point is the least glamorous and the most frequently decisive. A will must be executed in accordance with the Wills Act: in writing, signed by the testator (or by some other person in his presence and by his direction), with the signature made or acknowledged in the presence of two or more witnesses present at the same time, who then attest and subscribe the will in the testator's presence.

Each element does work. Witnesses who sign separately, in different rooms or on different days, do not satisfy the requirement that they be present at the same time. And a beneficiary who witnesses the will, or whose spouse witnesses it, generally forfeits the gift — the will stands, but the legacy fails. Home-made wills and wills executed hurriedly in hospital are where these problems cluster.

Testamentary capacity

The classical test, applied throughout the common law world and in Singapore, comes from Banks v Goodfellow (1870) LR 5 QB 549. The testator must understand the nature of the act of making a will and its effects; understand the extent of the property of which he is disposing; be able to comprehend and appreciate the claims to which he ought to give effect; and be free from any disorder of the mind that perverts his sense of right or prevents the exercise of his natural faculties.

Two points about the burden of proof matter more than the test itself. The legal burden lies on the person propounding the will. But where a will is rational on its face and duly executed, capacity is presumed, and it is for the challenger to raise a real doubt before the propounder is put to proof. A challenge founded on the assertion that an elderly testator "was not himself" will not survive that presumption without evidence.

The evidence that decides these cases is medical and contemporaneous: hospital records, the general practitioner's notes, cognitive assessments, and above all the drafting solicitor's attendance notes. Where a solicitor took proper instructions from a frail or elderly testator, made a record of his assessment and — following the golden rule of practice — arranged for a medical practitioner to witness the will and record an opinion on capacity, a challenge is very hard indeed. Where no note exists at all, the position is considerably more open.

Want of knowledge and approval

A testator must know and approve the contents of the will. Ordinarily this is presumed from capacity and due execution. But where the circumstances excite the suspicion of the court — the principal beneficiary drafted the will, or took the testator to the solicitor and interpreted for him, or the testator was blind, illiterate or signing in a language he did not read — the propounder must affirmatively prove that the testator understood and approved what he signed.

This is frequently the strongest ground available, because it does not require proof of any wrongdoing. It requires only suspicious circumstances, which the challenger can often establish from the file, and then places the burden on the party defending the will.

Undue influence

Undue influence in probate is a narrow and demanding ground, and it is not the same doctrine that operates in the law of contract and gifts made during life. There is no presumption of undue influence in probate: it must be proved, and what must be proved is coercion — that the testator's volition was overborne, so that the will represents somebody else's wishes rather than his own. Persuasion, appeals to affection, even the exercise of considerable pressure by a family member, do not by themselves suffice.

Because coercion is rarely documented, the ground succeeds only where the surrounding evidence is strong: isolation of the testator, control of his correspondence and finances, a sudden change of testamentary pattern in favour of the person exercising the control, and an absence of any independent advice. Pleaded without that material, an allegation of undue influence is close to an allegation of fraud, and it will attract the costs consequences that follow an unproved allegation of that character.

Forgery, fraud and revocation

Forgery is a straightforward allegation that requires handwriting evidence and rarely anything else. Fraudulent calumny — poisoning the testator's mind against a natural beneficiary by dishonest representations — is distinct from undue influence and can succeed where undue influence fails. And a will may be perfectly valid when made and yet revoked afterwards: by a later will or codicil, by destruction with the intention of revoking, or by the testator's subsequent marriage, which under the Wills Act revokes an earlier will save in defined circumstances.

Preserving your position: the caveat

The practical first step is procedural, and it is time-sensitive. A person with an interest in the estate may enter a caveat, which prevents a grant of probate or letters of administration being issued without notice to him. A caveat is effective for a limited period and may be renewed.

Its purpose is to buy time to investigate, not to obstruct. Once a caveat is entered, the party seeking the grant may issue a warning, to which the caveator must respond by entering an appearance setting out his interest. If he does not, the caveat ceases to have effect and the grant proceeds. If he does, the matter becomes contentious and proceeds as a probate action.

Alongside the caveat, the single most useful investigative step is a written request to the solicitor who drew the will for a statement of the circumstances in which it was prepared and executed, together with the file. The practice — familiar in England as a Larke v Nugus request and followed in substance across the common law world — is that a solicitor should assist. The answer will very often decide whether there is a case at all.

The other claim: provision out of the estate

A person who cannot impugn the will may still be able to claim provision from the estate under the Inheritance (Family Provision) Act. The Act is deliberately narrow, and it is much narrower than its Australian and English counterparts.

It applies only where the deceased died domiciled in Singapore.
The class of applicants is limited — broadly, a surviving spouse, an unmarried daughter, an infant son, and a son or daughter under a disability. There is no general category of persons maintained by the deceased, as there is in England.
The standard is maintenance. The court asks whether the disposition of the estate makes reasonable provision for the applicant's maintenance — not whether the estate has been divided fairly, and not what the applicant deserves.
The deadline is short. An application must ordinarily be made within six months of the grant of representation, and extensions are not to be assumed.

Anyone comparing outcomes across jurisdictions should note how differently this is handled elsewhere. Australia's family provision regimes admit a far wider class of eligible applicants, as our guide to contesting a will in Australia explains, and the English Act extends to cohabitants and to any person maintained by the deceased, as we set out in our guide to Inheritance Act claims in England and Wales. A claim that would be straightforward in Sydney or London may have no home at all in Singapore.

Muslim estates

The estate of a Muslim who dies domiciled in Singapore is governed by the Administration of Muslim Law Act and by the applicable rules of Muslim inheritance law. The shares of heirs are fixed under faraid, and the Syariah Court may issue an inheritance certificate identifying the heirs and their proportions. A will has a limited role: broadly, a Muslim testator may dispose by will of no more than one third of the estate, and not to those who take as heirs, save with the consent of the heirs.

The consequence is that the analysis in the rest of this guide does not transfer. Advice on a Muslim estate must begin with the applicable inheritance rules, not with the Wills Act.

Who pays for all this

There is a persistent belief that the estate pays the costs of any dispute about the estate. It is not the modern position. The general rule is that costs follow the event, and an unsuccessful challenger will ordinarily be ordered to pay the costs of the party defending the will — a serious exposure where the estate is modest and the litigation has been fought.

Two long-standing exceptions survive. Where the litigation was caused by the conduct of the testator or of those interested in the residue — an ambiguous will, a suspicious execution, a missing file — the costs may come out of the estate. And where the circumstances reasonably called for investigation, the court may make no order as to costs, leaving each side to bear its own. Both exceptions reward the challenger who investigated properly before issuing and pleaded only what the evidence supported. Neither rescues a speculative allegation of undue influence. Our guide to costs orders sets out the general rule and its exceptions in more detail.

If a will has been made that you believe does not reflect the deceased's intentions, the sequence is: enter a caveat to stop the grant, request the drafting solicitor's file, obtain the medical records, and only then decide which ground — if any — the evidence will actually support. If you are working through that sequence and want to test the grounds against your own facts before instructing anybody, CommonBench's Legal Chat can take you through the elements and the authorities.
