Key Takeaways

What is wills variation?

Wills variation is a legal process under WESA Section 60 that allows certain people to ask the BC Supreme Court to change the distribution in a will. Unlike some jurisdictions where a will is absolute, BC law imposes a moral and legal obligation on will-makers to provide for their spouse and children.

If the court finds that a will doesn't make "adequate provision" for a spouse or child, it can rewrite the distribution — sometimes dramatically.

Who can make a wills variation claim?

Only two categories of people:

No one else can bring a wills variation claim — not siblings, not parents, not friends, not charities. The right is limited to spouses and children only.

The 180-day deadline

A wills variation claim must be filed in the BC Supreme Court within 180 days of the grant of probate. This is a hard deadline. Courts have very limited discretion to extend it.

This is also why executors should wait at least 210 days before distributing estate assets — to allow for possible claims plus processing time.

What the court considers

When deciding whether to vary a will, the court looks at two separate sets of considerations:

Legal obligations

These are obligations that would be enforceable during the will-maker's lifetime:

Moral obligations

This is where it gets subjective. The court asks: would a "judicious parent" or "judicious spouse" have made this provision? Factors include:

Spouses and wills variation

Spousal claims are the strongest. BC courts consistently hold that a long-term spouse is entitled to a fair share of the estate, regardless of what the will says. A will that completely disinherits a surviving spouse of a decades-long marriage will almost certainly be varied.

The court's approach is roughly analogous to family law: if the couple had divorced, what would the spouse have received? The estate should provide at least that much.

Children and wills variation

Children's claims are more complex and depend heavily on the circumstances:

Minor or dependent children

A will that fails to provide for minor or financially dependent children will very likely be varied. The moral obligation to provide for dependent children is strong.

Adult independent children

This is the more contested area. The leading BC case (Tataryn v. Tataryn Estate, a Supreme Court of Canada decision) established that adult independent children have a weaker moral claim than spouses or dependent children, but they're not without rights.

Courts consider:

What counts as a "valid and rational reason"? The will-maker's stated reasons matter, but only if they're objectively supportable. "I never liked them" is not sufficient. "We have been estranged for 20 years after they committed fraud against me" may be. The bar is higher than many people expect.

How to reduce the risk of your will being varied

You cannot prevent a wills variation claim entirely — it's a statutory right. But you can reduce the likelihood of success:

The executor's role in variation claims

If a variation claim is filed, the executor must:
