Key takeaways
  • WESA section 60 allows only the will-maker's spouse or children to bring a wills variation claim, and it names no other relatives or beneficiaries.
  • A will can still be challenged on other grounds, such as lack of mental capacity, defective formalities or undue influence.
  • Whether a stepchild or grandchild fits within section 60 is a legal question that depends on the facts and should be confirmed with a lawyer.

If you are a stepchild or grandchild left out of a will, you may feel you were treated as family in every way except on paper. The law of wills variation is narrower than many people expect.

This article explains who the statute names, what other grounds may be open, and what steps are available to anyone with an interest in an estate.

This article covers the law of British Columbia.

Who can bring a wills variation claim

Only the will-maker's spouse or children can bring a wills variation claim under section 60 of the Wills, Estates and Succession Act (WESA). The section names no other relatives, beneficiaries or interested persons.

The section's wording refers to spouses and children and does not mention stepchildren or grandchildren. How this applies to you depends on your situation, so it is worth confirming with a lawyer before you assume either answer.

One related point: a parent-child relationship created by adoption is determined under the Adoption Act, and an adopted child is not entitled to the estate of a pre-adoption parent except through that parent's will.

Spouses are also defined narrowly

WESA also defines who counts as a spouse, which can matter when a will-maker had a partner. Two people are spouses if they were married to each other, or if they had lived with each other in a marriage-like relationship for at least 2 years, generally judged as of the date of death.

Other ways to challenge a will

A wills variation claim is not the only route. A will can be attacked on validity grounds, and these may be worth discussing with a lawyer if you have a real concern.

GroundWhat the law says
CapacityA person who is 16 or older and mentally capable may make a will; a will made without capacity can be challenged
FormalitiesA will must be in writing and signed at its end in the presence of 2 or more witnesses present at the same time, who then sign in the will-maker's presence
Undue influenceIf a claimant shows the potential for dependence or domination, the party defending the will has the onus of proving no undue influence was exercised

Even a will that does not meet the formalities can be upheld, because the court may order that a record or document, including electronic data, is fully effective as the will-maker's will. Who has standing to raise these grounds depends on the facts.

Steps and deadlines for interested persons

Before a grant is applied for, the applicant must deliver a notice of proposed application in Form P1 to the persons listed in Rule 25-2(2), including each beneficiary under the will and those who would be intestate successors. The application cannot be made until at least 21 days after delivery.

A person who is or must be given that notice, or who claims an interest under a prior or subsequent will, may file a notice of dispute in Form P29 before the earlier of the issue of an authorization or the estate grant. While it is in effect, the registrar must not issue the grant.

If a wills variation claim is available to anyone, it must be started within 180 days from the date the grant is issued in British Columbia. A copy of the initiating pleading must be served on the executor no later than 30 days after that period expires, unless the court extends the time for service.

If the will-maker has minor children, or a spouse or child is mentally incapable, the pleading must also be served on the Public Guardian and Trustee, or the claim will not be heard. A personal representative must not distribute the estate within 210 days after the grant is issued unless the court orders otherwise, although earlier distribution is possible if all beneficiaries and all persons who may bring a wills variation proceeding consent.

What to do next

Frequently asked questions

Is a stepchild a child under WESA section 60?

Section 60 refers to the will-maker's spouse or children and names no other relatives or interested persons. Whether a stepchild is included depends on your situation, so it is worth confirming with a lawyer before relying on it.

Can a grandchild make a wills variation claim?

The section names only spouses and children. A grandchild might have other grounds, for example if the will itself is invalid, which depends on the facts.

What if the will was made when the person lacked capacity?

A will made without mental capacity can be challenged as invalid. How this applies depends on your situation, so it is worth confirming with a lawyer.

Is there a deadline for a stepchild or grandchild?

Any wills variation proceeding must be started within 180 days of the grant. Other steps, such as a notice of dispute, must be filed before the earlier of the issue of an authorization or the estate grant.
