Key takeaways
  • The Supreme Court of Canada in Tataryn measured an "adequate, just and equitable" provision by two norms: legal obligations and moral obligations.
  • Where an estate cannot meet every claim, legal obligations generally come ahead of purely moral ones.
  • Only a spouse or child can bring a wills variation claim, and the claim must be started within 180 days of the grant.

If you are a spouse or child who feels a will left you too little, you will keep running into one name: Tataryn. It is the Supreme Court of Canada decision that British Columbia courts have long used to decide what a fair provision looks like in a wills variation claim.

This article explains the test in plain words, how its two kinds of obligation fit together, and what else shapes a claim. How a court weighs these ideas turns heavily on the facts of each family, so treat this as background and not a forecast.

This article covers the law of British Columbia.

Where the test comes from

Section 60 of the Wills, Estates and Succession Act (WESA) lets the court order that adequate, just and equitable provision be made from an estate when a will does not make adequate provision for the proper maintenance and support of the will-maker's spouse or children.

The words "adequate, just and equitable" are broad. In Tataryn v. Tataryn Estate, 1994 CanLII 51 (SCC), the Supreme Court of Canada explained that this standard is measured by two norms. Those two norms are the core of what people mean by the Tataryn test.

The two norms: legal and moral obligations

NormWhat it asksPlain-words example
Legal obligationsWhat the law would have required of the will-maker during lifeSupport the will-maker would have owed a spouse or child while alive
Moral obligationsSociety's reasonable expectations of what a judicious person would do, judged by contemporary community standardsWhat an ordinary, fair-minded parent or partner would be expected to do

The moral side is not about what you personally feel you deserve. It asks what the community would reasonably expect, which is why two families with similar wills can end up with different outcomes.

How competing claims are ranked

Tataryn also deals with what happens when more than one person has a claim. Where the estate is large enough, all claims should be met. Where priorities have to be set, claims based on legal obligations generally take precedence over purely moral claims, and some moral claims may be stronger than others.

In practice, this matters most in modest estates, where meeting one person's claim leaves less for another.

What else shapes a claim today

Tataryn is the starting framework, but a court looks at the whole picture. How later decisions treat adult children, estrangement, or relatives such as stepchildren and grandchildren depends on the facts and is worth discussing with a lawyer who can check the current case law.

Who can claim, and the clock

Only the will-maker's spouse or children can bring the claim. Two people are spouses if they were married, or had lived together in a marriage-like relationship for at least 2 years.

There are exceptions. Married spouses stop being spouses for WESA purposes when an event such as separation gives rise to an interest in family property under the Family Law Act. Spouses are not treated as separated if, within one year, they resume living together mainly to reconcile and do so for periods totalling at least 90 days. An unmarried partner whose relationship ended before the death is not a spouse who can claim.

The claim must be started within 180 days from the date the grant is issued in British Columbia. The pleading must be served on the executor no later than 30 days after that period expires, unless the court extends the time for service.

What to do next

Frequently asked questions

What is the Tataryn test in simple terms?

It is the way the Supreme Court of Canada said to measure whether a provision is adequate, just and equitable. The court looks at the legal obligations the will-maker had in life and the moral obligations a judicious person would be expected to meet by community standards.

Do legal or moral obligations come first?

Where the estate cannot satisfy every claim, claims based on legal obligations generally take precedence over purely moral claims. Some moral claims may be stronger than others.

Can a stepchild or grandchild bring a wills variation claim?

Section 60 names only the will-maker's spouse or children. Whether other relatives can fit within that wording depends on the facts and the case law, so ask a lawyer before relying on it.

How long do I have to start a claim?

The proceeding must be started within 180 days from the date the grant is issued in British Columbia. Service on the executor is due within a further 30 days, unless the court extends the time for service.
