Key takeaways
  • A Court of King's Bench judge can order maintenance and support out of an estate, even against a will, where a dependant's resources are insufficient.
  • The deadline is four months after the death, not after probate, and a later application is only possible for part of the estate still undistributed if a judge finds it just.
  • Being disappointed or left out of a will is not, by itself, a ground to have the will declared invalid.

Finding out that a will leaves you little or nothing can be a shock, especially if you depended on the person who died. Many people assume the will is the last word. In New Brunswick, it is not always.

There are different routes for different situations: a support claim for dependants, a separate property claim for married spouses, and a challenge to the will itself. This article explains how they differ, and why the timing matters so much.

This article covers the law of New Brunswick.

What the Provision for Dependants Act allows

Under the Provision for Dependants Act, a judge of the Court of King's Bench may order maintenance and support out of the estate where the dependant's resources are insufficient. The judge can do this even against the terms of a will.

The judge may also suspend administration of the estate while the claim is dealt with. The application is made by notice of application.

Who counts as a dependant

Common-law partners are not automatically left out. The Family Law Act applies the spousal support obligation to common-law partners who have cohabited continuously for not fewer than three years with one substantially dependent on the other, or who have cohabited in a situation of some permanence with a child born of whom they are parents. A partner who meets that test may apply to the Court of King's Bench within the four-month limit. Whether a particular partner qualifies depends on the facts, so it is worth getting advice.

The four-month deadline

No application under the Act may be made later than four months after the death. The clock runs from the death, not from the grant of probate, so you should not wait to see how the estate is administered.

There is a limited exception. A judge may allow a later application for any part of the estate still undistributed, if the judge considers it just. This is not something to count on.

Even a timely claim can fail. A judge may refuse an order if the applicant's character or conduct disentitles them.

Married spouses: a separate marital property claim

A surviving married spouse has another option. They may apply to the Court to have marital property divided in equal shares as against the deceased's estate. This is available to married spouses only.

That application must also be made within four months of death. The period can be extended if the spouse did not know of the death or was prevented by circumstances beyond their control.

Support claim versus challenging the will

A support claim does not ask the court to say the will is invalid. It asks for provision out of the estate despite the will. Challenging a will is different. Grounds such as lack of testamentary capacity, undue influence, fraud, or lack of knowledge and approval are decided under common-law principles.

Simply being disappointed or excluded is not itself a ground to set a will aside. On fraud or undue influence, the burden is on those attacking the will.

What to do next

Frequently asked questions

Can a judge really override a will?

Yes, in a support claim. A Court of King's Bench judge may order maintenance and support out of the estate where a dependant's resources are insufficient, even against a will. The judge may also suspend administration of the estate.

Does the four months start when probate is granted?

No. The four-month limit runs from the death. A judge may allow a later application only for part of the estate still undistributed, if just.

Can my common-law partner claim support?

Possibly. A common-law partner who meets the Family Law Act test, such as three years of continuous cohabitation with substantial dependence, may apply within the four-month limit. Whether you qualify depends on your facts.

Is being left out of a will enough to cancel it?

No. Simply being disappointed or excluded is not itself a ground to challenge a will. Challenges rest on grounds such as capacity, undue influence, fraud, or lack of knowledge and approval.
