When Can a Child Be Disinherited? Understanding Estrangement, Misconduct, and Valid and Rational Reasons Under WESA

Disinheriting an adult child can be a contentious issue in wills and estate litigation. While British Columbia’s Wills, Estates and Succession Act (WESA) allows will-makers wide freedom to distribute their estate as they choose, the courts retain the power to vary a will when adequate provision has not been made for a spouse or child.

But when, exactly, can a child be disentitled to relief under WESA? Courts have identified several categories of relevant considerations: the nature of the parent–child relationship (including estrangement), the child’s misconduct, and the will-maker’s stated reasons for disinheriting the child.

Estrangement in the Parent–Child Relationship

Estrangement does not automatically erase a parent’s moral obligation to provide for a child. Courts rarely accept estrangement on its own as a justification for cutting a child out of a will.

If the distance in the relationship arose from the parent’s own behaviour, such as neglect or long periods of absence, the court may step in and restore the child’s share. The same applies when the estrangement was caused by circumstances the child could not control. For example, a parent might have been prevented from seeing the child because the other parent blocked access. In situations like these, the moral duty usually remains.

Courts examine the entire history of the relationship. They look at who contributed to the breakdown, whether the parent treated the child fairly, and whether the child ever had a real chance to rebuild the connection.

Estrangement can justify disinheritance, but only in limited situations. It must be lengthy, and it must be caused by the child’s own behaviour rather than the will-maker’s. When the child is responsible for the breakdown and the parent acted reasonably throughout, the court may find that there is no remaining moral obligation to provide for that child.

Misconduct by the Child

BC courts set a high bar for disinheriting a child based on poor behaviour. The court will only uphold disinheritance when the behaviour is truly extreme.

Serious misconduct can include abusive treatment of a parent or the misuse of a parent’s assets for personal gain. In these situations, the conduct is so damaging that it warrants disheritance.

Most disappointing behaviour does not qualify. Courts have rejected disinheritance where a child chose a partner the parent disliked, removed small items from the home, failed to stay in touch, or struggled with money.

The standard is strict. Only actions that deeply undermine the parent-child relationship or are profoundly inappropriate will justify cutting a child out of a will.

Valid and Rational Reasons for Disinheritance

Even when misconduct or estrangement is involved, the will-maker must still have valid and rational reasons for disinheriting a child. The law requires more than strong feelings or long-held grudges.

Valid means the reasons are based on true facts. Rational means those facts logically support the decision to cut the child out. This test does not require the will-maker’s reasoning to be kind or morally popular. A parent can make a hard choice, as long as the decision is grounded in reality.

Courts will uphold disinheritance when the will-maker’s beliefs are accurate. For example, a parent may leave the estate to a child with genuine financial need or may reward someone who provided meaningful care and support. If those reasons are factually correct, the court will often respect them.

Problems arise when the parent relied on mistaken assumptions. If the parent misunderstood the family dynamics, overlooked a child’s contributions, or believed something that was simply untrue, the court can step in and vary the will.

What Families and Executors Should Keep in Mind

Disinheriting your child is legally possible in British Columbia, but courts examine the circumstances with great care. Estrangement is not sufficient on its own because the court focuses on how and why the relationship broke down. Misconduct must be truly severe before it can justify excluding a child. The will-maker’s stated reasons must be accurate and logically connected to the decision. Courts will intervene when necessary to ensure that a will reflects the legal and moral obligations owed to a child.
