Estate Planning With an Estranged Child in Canada
Estrangement is one of the hardest situations a will has to carry. A parent who has not spoken to an adult child in fifteen years wants to leave them out — not out of spite, but because the relationship simply ended — and worries in equal measure about two things: whether they are even allowed to, and whether doing so will drag the rest of the family into a courtroom. The honest answer is that in most of Canada you can disinherit an estranged adult child, but how you do it determines whether your will survives the challenge that often follows.
This guide explains the legal freedom you have, the two limits on it, and the practical steps that make a disinheritance more defensible. It is general information for the common-law provinces and territories, not advice; disinheritance is exactly the kind of decision that warrants a lawyer.
The general rule — testamentary freedom
Across most of Canada, a competent adult can generally leave their estate as they choose, and an independent adult child has no automatic right to a share.[3] You can divide unequally, and you can leave a child out. That freedom is the legal starting point, and for many provinces it is close to the finishing point too.
Two limits qualify it, and they matter enormously depending on where you live and on your child's circumstances.
Limit one — dependant support
The first limit is dependant relief. If your child relied on you for support — because of age, disability, or other circumstances — provincial law generally treats them as a dependant who can claim provision from your estate, regardless of estrangement.[2] You cannot use a will to cut off someone the law says you were responsible for supporting. For a child with a disability, the answer is usually to plan for them, often through a properly structured trust, rather than to attempt to exclude them. Our guide on dependant relief in Canada covers this in depth.
Limit two — British Columbia
The second limit is geographic. British Columbia stands apart: under the wills variation provision of its Wills, Estates and Succession Act, a court can vary a will that fails to make adequate, just, and equitable provision for a spouse or child — and that includes a financially independent adult child.[1] BC courts assess a parent's moral obligations through an objective lens of what a reasonable, judicious parent would do, measured against current social norms. The practical consequence is that a flat disinheritance of an adult child is far more exposed in BC than elsewhere, and even valid, rational reasons may not fully defeat a variation claim. If you live in BC, get province-specific advice before disinheriting.
How to disinherit more safely
Where the law permits disinheritance, the goal is a will that holds up. The most useful steps:
- Be explicit. Name the child and state that the omission or reduced gift is intentional. Silence invites an argument that you simply forgot them.
- Record your reasons. A contemporaneous, factual memorandum or your lawyer's notes — kept with the file — help, particularly in defending a BC variation claim where reasons are weighed. Keep them measured and truthful; an inflammatory letter can backfire.
- Shore up capacity and independence. A disinherited child frequently challenges on lack of testamentary capacity or undue influence rather than on fairness. Documenting capacity and using an independent lawyer closes those doors.
- Consider where the assets sit. Assets that pass by beneficiary designation or survivorship generally fall outside the estate, reducing what is available to a claim — though this interacts with provincial rules, so take advice.
- Weigh a token gift versus nothing. A small gift can signal the child was not forgotten, but it also makes them a beneficiary. Reasonable lawyers disagree; decide with one.
The leading Canadian decision on a parent's freedom to disinherit an independent adult child is discussed in our explainer on the Spence v. BMO Trust disinheritance case.
Plan for reconciliation, too
Estrangements sometimes end. If you want a path back, say so in the will rather than leaving it to chance — for example, a gift that takes effect only if certain conditions are met, drafted carefully so it is clear and enforceable. Ambiguous "if we reconcile" language causes more disputes than it prevents, so this is a place for precise drafting.
What we focus on at It's Simple Will
The Will Creator helps you state your wishes clearly, which is half the battle in any contested estate. But disinheritance — especially of a dependant, or anywhere in British Columbia — is a situation where a lawyer-assisted will and documented reasons are worth the cost, and our guides are meant to prepare you for that conversation. For the broader context on what children can claim, see adult children inheriting from parents.

Frequently asked questions
Can I disinherit an estranged adult child in Canada?
In most provinces, generally yes — testamentary freedom lets you decide who inherits, and an independent adult child has no automatic entitlement. The main exceptions are a child who was financially dependent on you, who may claim support, and British Columbia, where the law allows even independent adult children to challenge an unfair will.
Why is British Columbia different?
Under its Wills, Estates and Succession Act, a court can vary a will that fails to make adequate, just, and equitable provision for a spouse or child — including an independent adult child. BC courts weigh a parent's moral obligations using an objective standard, so a bare disinheritance is more vulnerable there than elsewhere in Canada.
How do I disinherit a child as safely as possible?
Where the law allows it, be explicit — name the child and state that the omission is intentional — and record your reasons in a way your lawyer can preserve. Make sure your capacity is documented and the will is free of undue influence, because a disinherited child often challenges on those grounds rather than on fairness.
Should I leave a token gift instead of nothing?
It is a judgment call. A modest gift signals the child was not forgotten, which can blunt a claim, but it also gives them standing as a beneficiary. Lawyers differ on this, and the right choice depends on your province and your family. Discuss it with an estate lawyer.
Can a no-contest clause stop a challenge?
Only partially. A no-contest (in terrorem) clause can discourage challenges by threatening to cancel a gift if the beneficiary sues, but its effect is limited, it only bites if you actually leave the person something to lose, and courts will not let it block legitimate dependant-relief or variation claims.
What if my estranged child depended on me?
Then you generally cannot simply cut them off. A child who relied on you for support — for example because of a disability — is a dependant, and dependant-relief law can require provision from your estate regardless of estrangement. Plan for them, often through a properly structured trust.
