No-Contest Clauses in Canadian Wills (In Terrorem)
A no-contest clause in a Canadian Will attempts to deter beneficiaries from challenging the Will by threatening them with loss of their gift if they do. Unlike some U.S. states, where no-contest clauses can be enforced quite broadly, Canadian courts treat them as a deterrent, not an absolute bar — enforceability depends heavily on the type of challenge and provincial law, and a clause that tries to shut down a dependant's statutory claim can simply be struck down.[1]
What an in terrorem clause looks like
Standard wording:
"Should any beneficiary, directly or indirectly, contest or attempt to invalidate this Will or any provision of it, that beneficiary shall be deemed to have predeceased me and shall forfeit all gifts, bequests, and entitlements under this Will. The portion that would have gone to such beneficiary shall instead pass to [named alternate beneficiary or charity]."
The clause has three elements:
- Trigger — what counts as a contest
- Consequence — beneficiary loses their gift
- Gift-over — what happens to the forfeited share
When these clauses work
Speculative or frivolous challenges. When a disappointed beneficiary has no real legal grounds and is "rolling the dice," an in terrorem clause is a genuine deterrent.
Properly drafted clauses with gift-over. The clause must specify what happens to the forfeited gift. Without a clear gift-over, the threat is hollow and the clause is often unenforceable.
Adult non-dependant beneficiaries. Where the beneficiary has no statutory protection (BC's Wills, Estates and Succession Act variation provisions, Ontario's Succession Law Reform Act dependant relief, equivalents), the clause has more force.
When these clauses fail
Legitimate dependant relief claims. Provincial dependant relief / wills variation statutes protect specific classes of dependants regardless of Will provisions. Courts have held a no-contest clause void, as against public policy, where it purports to block:
- A surviving spouse's or dependant's claim for adequate provision or variation (BC, Ontario, several provinces)
- An infant or adult child with actual dependency
- A common-law spouse with statutory protection
The dependant can pursue their claim and still inherit; in terrorem clauses are not enforced against legitimate dependant relief, regardless of whether the clause is otherwise well drafted.
Note on "good faith" or "reasonable grounds" — this is narrower in Canada than in some U.S. states. A number of American jurisdictions recognize a broad "probable cause" exception that excuses any good-faith challenge from triggering a no-contest clause. Canadian courts have not adopted an equivalent general doctrine. Instead, the Canadian carve-outs are narrower and more specific: the clause must have a genuine gift-over or it is treated as an idle threat and is void, and it cannot oust a beneficiary's statutory entitlement (dependant relief, wills variation, or a right expressly conferred by provincial estates legislation). Outside those specific carve-outs, Canadian appellate authority has read no-contest clauses fairly robustly — an Alberta Court of Appeal decision held that even applying to the court for formal proof of a Will, based on suspicion about how it was signed, was enough to trigger forfeiture, because a merely procedural right to challenge a Will is not the kind of statutory "right or benefit" the courts treat as protected.[1] Do not assume a good-faith or well-founded challenge is automatically safe from forfeiture in Canada — that protection is not general, and it should not be relied on without a lawyer's advice on the specific clause and province.
Will entirely invalidated. If a court finds the Will invalid (e.g., lack of testamentary capacity, undue influence, improper execution), the in terrorem clause falls with the rest of the Will.
Vague drafting. Clauses that don't specify what counts as a "contest" or what happens to the forfeited gift are often unenforceable.
What counts as a "contest"
Courts have considered:
Clear contests:
- Filing a court application to invalidate the Will
- Seeking to set aside specific provisions
- Challenging executor's authority
Generally NOT contests:
- Requesting accountings or information
- Asking the executor questions
- Seeking interpretive ruling on ambiguous provisions
- Filing a dependant relief application (in many provinces)
- Negotiating with the estate
Borderline:
- Filing a will variation claim in BC (WESA — the Wills, Estates and Succession Act — explicitly permits these claims; in terrorem clauses generally don't block them)
- Mediation requests
- Specific provincial procedures
Provincial variation
Each Canadian province has specific law on in terrorem clauses:
British Columbia. WESA (Wills, Estates and Succession Act) variation claims are not blocked by in terrorem clauses. The legislature deliberately preserved variation rights.
Ontario. Generally enforceable for speculative or frivolous challenges; legitimate dependant relief under SLRA Part V typically not blocked.
Alberta, Saskatchewan, Manitoba, Atlantic provinces. Specific provincial dependant relief / family relief statutes; in terrorem clauses subject to similar limitations.
Specific case law in each province addresses specific situations.
Drafting effective no-contest clauses
If using an in terrorem clause:
- Specify the trigger clearly. What exact actions constitute a contest?
- Specify the consequence. Beneficiary loses everything? Specific gifts only?
- Include a gift-over. Where does the forfeited share go?
- Carve out legitimate inquiries. "Nothing in this clause prevents a beneficiary from seeking information about the estate, requesting accountings, or pursuing dependant relief claims under applicable provincial law."
- Make the gift-over attractive to a residual beneficiary. If a sibling stands to gain from another sibling's forfeiture, the clause has more force.
When NOT to use this clause
- When all beneficiaries are happy. No deterrent needed.
- When the disappointed beneficiary has strong dependant relief claim. Clause won't work; may incentivize them.
- When the clause is so harsh that a court would invalidate it. Overly punitive provisions are sometimes struck down.
Alternative approaches
Mediation requirement. Will provides that disputes must go to mediation before court. Less punitive than in terrorem.
Explanatory letter. Letter of wishes accompanying the Will explains reasoning for distribution. Doesn't deter challenges legally but provides context that may reduce litigation appetite.
Discussion with beneficiaries during life. Explaining the Will to family before death often reduces post-death disputes. Most useful when family dynamics permit.
Trust structures. Some inheritance structured as discretionary trust with broader scope removes specific provisions to challenge.
What we focus on at It's Simple Will
The Will Creator does not currently offer in terrorem clause options as a built-in feature. For specific contest deterrents, discussion with a Canadian lawyer is appropriate — drafting requires care and the law varies significantly by province. A local estates lawyer can also be found through a provincial or the national law society / bar association referral service.[2]

Frequently asked questions
What's an in terrorem clause?
A Will provision that threatens beneficiaries with loss of their gift if they challenge the Will. 'In terrorem' is Latin for 'as a threat'. Common wording — 'Any beneficiary who contests this Will or any provision shall be deemed to have predeceased me and shall receive nothing.' The purpose is to deter litigation by making contest expensive even if unsuccessful.
Are these clauses enforceable in Canada?
Mixed — not uniformly enforceable the way they can be in some U.S. states. Canadian courts have generally upheld properly drafted clauses (with a gift-over) as a deterrent against frivolous or speculative challenges. But a no-contest clause is void, as against public policy, to the extent it tries to block a beneficiary's statutory rights — most importantly a dependant's claim for support or variation under provincial family-law and wills-variation statutes (BC's Wills, Estates and Succession Act, Ontario's Succession Law Reform Act, and equivalents elsewhere). The protection of dependants supersedes the testator's wishes.
What's a 'gift-over' and why does it matter?
A gift-over names who receives the gift if the beneficiary loses it through contest. Without a gift-over, the clause may be unenforceable because the threat doesn't have a clear consequence. With a gift-over, the contesting beneficiary's share goes to a named alternative (often another family member or charity).
What if the contest succeeds?
If the Will is invalidated entirely, the no-contest clause goes with it. If only specific provisions are struck down, the no-contest clause may apply to other provisions or may also be void depending on circumstances. Specific to provincial case law.
Can I prevent my child from contesting my Will?
You can include an in terrorem clause, but it's not a guarantee. If the child has dependant relief rights (typically requires showing actual dependency), provincial law protects those rights regardless of clause. For non-dependant adult children, the clause can be effective deterrent if drafted properly with gift-over.
Should I include this in my Will?
Depends on circumstances. Useful when family dynamics suggest contest risk. Drafting requires precision — vague clauses are often unenforceable. Discuss with lawyer if there are specific concerns about contests from specific beneficiaries.
