No-contest clauses, sometimes called forfeiture or in terrorem clauses, are provisions inserted into a will to discourage beneficiaries from challenging it. The idea is simple: if you contest the will and lose, you lose your inheritance as well. In practice, though, the position in England and Wales is more nuanced than many people assume. Courts take a careful view of these clauses, balancing the testator's wishes against the beneficiary's right to bring a genuine claim. If you are drafting a will and considering adding one, or you have been named in a will that contains one and you are unsure whether to challenge it, the practical effect of the clause depends heavily on the circumstances. This guide explains how these clauses tend to work, where they bite, and where they do not.

What this document is

A no-contest clause is a written provision in a will that says a beneficiary who challenges the will, and fails, forfeits whatever they would otherwise have received. The beneficiary's gift usually passes instead to another named person or falls into residue.

The label 'in terrorem' comes from the Latin for 'in fear', which captures the point: the clause works by making beneficiaries afraid to litigate. In England and Wales, these clauses are not automatically unenforceable, but they are not a guaranteed shield either.

The courts look closely at what the clause actually says, whether the challenge brought was reasonable, and whether the beneficiary had probable cause to bring it. A clause that attempts to stop someone bringing a legitimate claim, for example under the Inheritance (Provision for Family and Dependants) Act 1975, may be read narrowly or treated as ineffective against that specific type of claim. The drafting matters enormously, which is why generic clauses copied from templates often underperform when tested.

How to use this document

  1. Work out what is actually being challenged. Not every dispute about a will is a 'contest' in the technical sense. A claim for reasonable financial provision under the 1975 Act is different from a challenge to the validity of the will itself. The type of claim affects whether a no-contest clause applies at all, so identify the nature of the dispute first. 2. Read the clause carefully, word by word. No-contest clauses vary enormously in scope. Some cover only challenges to validity, others extend to any proceedings 'touching or concerning' the will. The precise wording determines whether a particular action triggers forfeiture. Do not assume the clause does what it looks like it does on a first reading. 3. Identify the gift-over. A no-contest clause only works if there is somewhere for the forfeited gift to go. If the clause says 'any beneficiary who contests loses their share' but does not specify who receives it instead, courts may treat the clause as ineffective. Check whether the will names a substitute beneficiary or directs the gift into residue. 4. Assess the strength of any potential challenge. Before bringing a claim, take a realistic view of the grounds. Lack of capacity, undue influence, want of knowledge and approval, forgery and improper execution are the main routes. Weak or speculative claims are more likely to trigger forfeiture than well-founded ones supported by evidence. 5. Weigh the financial risk against the potential reward. Contesting a will is expensive and the outcome is never certain. If you stand to inherit a modest sum, the cost of litigation plus the risk of forfeiture may outweigh any likely gain. If the inheritance is substantial and the grounds are strong, the calculation shifts. Think carefully before issuing proceedings.

Common questions

Q Are no-contest clauses legally enforceable in England and Wales?
They can be, but enforcement is not automatic. English courts will generally give effect to a clearly drafted clause where there is a valid gift-over to another beneficiary. However, courts are reluctant to apply these clauses in a way that shuts out genuine claims, particularly those based on the will's validity or on statutory rights. Much depends on the exact wording and the nature of the challenge.
Q Does a no-contest clause stop a claim under the Inheritance Act 1975?
Not necessarily. A claim under the Inheritance (Provision for Family and Dependants) Act 1975 is a statutory claim for reasonable financial provision, not a challenge to the will itself. Courts have generally been cautious about letting a no-contest clause override a statutory entitlement, although the clause may still affect what the beneficiary takes under the will if the claim fails.
Q What happens if a beneficiary successfully contests the will?
If the challenge succeeds, the no-contest clause typically falls away with the rest of the offending provisions, because a successful challenge usually means the will, or part of it, is set aside. The beneficiary then takes under the earlier will or under the intestacy rules, depending on what the court decides. A successful claim does not trigger forfeiture.
Q Can a beneficiary ask the court whether a claim will trigger forfeiture?
In some situations, yes. A beneficiary may be able to seek the court's guidance through a construction claim, asking the court to decide whether a proposed action would actually fall within the scope of the clause. This can give clarity before committing to full proceedings, although it adds its own costs and is not available in every case.
Q Should I include a no-contest clause in my will?
It depends on your circumstances. If you are worried about disputes between beneficiaries and you are leaving unequal shares or cutting someone out, a carefully drafted clause with a proper gift-over can be a useful deterrent. It will not stop determined litigation, but it raises the stakes for anyone thinking about challenging your wishes on weak grounds.
Q Do no-contest clauses work the same way as in the United States?
No. American law, which varies state by state, has developed its own body of case law around these clauses, and some states treat them more strictly than others. English law has taken a different path and tends to focus on the drafting, the gift-over, and whether the beneficiary had probable cause. Do not assume US commentary reflects the position here.
Q Can a no-contest clause be removed or amended after the testator dies?
Not by a beneficiary acting alone. The will stands as written once the testator has died. However, beneficiaries can enter into a deed of variation to redistribute the estate by agreement, which can sidestep the issue in some cases. This requires the consent of the affected beneficiaries and meets certain formal requirements.
