Key takeaways
  • Capacity is presumed when a will is duly executed, but suspicious circumstances can shift the burden to the person propounding the will.
  • Undue influence and fraud must be proven by the person attacking the will.
  • A will that seems unfair is not necessarily invalid, and dependants may have separate claims under The Dependants' Relief Act, 1996.

Finding out that a family member left you less than you expected, or nothing at all, is painful. Many people ask whether they can contest the will. The answer depends on why you think the will is wrong, and on whether you have a legal basis to challenge it.

This article explains the main grounds people raise in Saskatchewan, who may have a claim, and what else may be available if the will is valid but unfair. Time limits can apply, so speak to a lawyer early.

This article covers the law of Saskatchewan.

Invalid versus unfair

Two different questions often get mixed up. The first is whether the will is valid at all. The second is whether a valid will left someone without enough. Courts treat them differently. Feeling that a will is unfair is not the same as having a legal ground, such as those below, to challenge it, and a lawyer can help you tell which situation you are in.

Some people have separate rights even when the will is valid. Dependants include a legal, common-law or same-sex spouse, children under 18, and adult children unable to support themselves due to disability, and they may claim under The Dependants' Relief Act, 1996 where the will makes inadequate provision.

The main grounds for challenging a will

GroundWhat it means in plain wordsWho must prove it
Lack of capacityThe person did not understand what they were signing or what they ownedWhere the will is duly executed, capacity is presumed, so the challenger starts at a disadvantage
Suspicious circumstancesFacts about how the will came to be made that raise doubt; what counts depends on the case, so it is worth confirming with a lawyerIf shown, the burden shifts to the person propounding the will
Undue influencePressure that overpowered the person's own wishesThe person attacking the will
FraudThe person was tricked about what the document was or saidThe person attacking the will
Improper signingThe will was not signed and witnessed as the law requiresDepends on the facts; the person seeking probate normally files an affidavit of execution

Testamentary capacity is a legal test decided by a court or lawyer, not by any single doctor or assessor. Medical records and witness evidence are often important.

Who can raise a challenge and how it starts

Whether you are in a position to challenge a will depends on your connection to the estate and on the facts, such as how the estate would pass if there were no will. Without a will, a spouse inherits the entire estate if all the children are also the spouse's, with different shares if there are children from another relationship. A spouse who had lived separate and apart from the deceased for two years takes no share on intestacy. Whether you have standing in your own case is a question for a lawyer.

Saskatchewan courts allow a will to be proven in solemn form (Rule 16-48) and a caveat to be filed. How a caveat works in practice, and whether it suits your situation, depends on the facts, so it is worth raising with a lawyer early. You can also find out whether an estate application has been filed by requesting a search of the Wills and Estates Registry in Regina, which costs $20 and lists estate applications filed since 1905, though only estates that went through court.

Because deadlines can be short, do not wait to see what the executor does before getting advice.

What to do next

Frequently asked questions

Can I contest a will just because it is unfair?

An unfair will and an invalid will are different questions, and the answer depends on the facts, so it is worth confirming with a lawyer. Separately, eligible dependants may claim under The Dependants' Relief Act, 1996 where the will makes inadequate provision.

Is it easy to prove someone lacked capacity?

It is difficult. Where a will is duly executed, capacity is presumed. Suspicious circumstances can shift the burden to the person propounding the will.

Who has to prove undue influence or fraud?

Those attacking the will bear the burden for both undue influence and fraud.

Is there a deadline?

Yes, in some situations. A surviving spouse's family property application cannot be started more than six months after the grant of probate or administration. Other time limits depend on the claim, so speak with a lawyer quickly.
