Key takeaways
  • A dependant support application generally cannot be made more than six months after the grant of letters probate or letters of administration.
  • A court may allow a late application, but only against the part of the estate still undistributed on the date of the application.
  • The general two-year limitation period does not replace this deadline, because the six-month rule applies instead.

If you were left out of a will, or the estate does not provide for you, and you relied on the deceased for support, the clock may already be running. The deadline for asking a court to order support from an estate is short.

This article explains the six-month rule, who can claim, what happens if you are late, and what happens to the estate while a claim is pending.

The six-month deadline

Under the Succession Law Reform Act (SLRA), the court may order that adequate provision be made out of the estate if the deceased, with or without a will, did not make adequate provision for the proper support of their dependants. An application for dependant support may not be made more than six months after the grant of letters probate of the will or of letters of administration.

The six months run from the grant, not from the death. The Limitations Act, 2002 lists SLRA s. 61 as a limitation period that applies instead of the general two-year rule. You should not assume you have two years.

For comparison, the general rule is that most claims must be started within two years after the day the claim was discovered. Claims by or against a deceased person's estate for torts or injuries, other than libel and slander, must be started within two years of the death. Which period applies to your situation depends on the type of claim, so it is worth confirming with a lawyer.

Who counts as a dependant

A dependant is the deceased's spouse, parent, child, or brother or sister to whom the deceased was providing support, or was under a legal obligation to provide support, immediately before death.

The dependant, or the dependant's parent, may apply, and certain agencies, including the Ministry and municipalities, may also apply in specified circumstances. There is no general duty to provide in a will for an adult, independent child.

Can you apply late?

Sometimes. The court may allow an application after the six months, but only against any portion of the estate still undistributed on the date of the application. Once the estate has been paid out, a late claim may have little to attach to, so waiting carries real risk.

Whether the court will permit a late application depends on the facts, and it is not something to count on. Get advice quickly if the date has passed.

What happens to the estate while a claim is pending

StepWhat the law says
Notice to the personal representativeOnce served with notice of the application, the personal representative must not distribute the estate until the court has disposed of the application.
ExceptionDistribution is allowed if everyone entitled to apply consents or the court orders otherwise.
Suspending administrationThe court may suspend administration of the estate, in whole or in part, for as long and to the extent it decides.
Setting supportThe court considers all the circumstances, including the dependant's age and health, future assets and means, and the claims of other dependants.

A court can make a support order even if the dependant signed an agreement or waiver saying otherwise.

Joint property and next steps

For these claims, a joint account that passes to the survivor, and property held by the deceased and another as joint tenants, are treated as testamentary dispositions at the date of death. They count toward the net estate only to the extent the funds or consideration came from the deceased, and the dependant must prove that.

A person with a financial interest in an estate can file Form 74P to ask the court to notify them when someone starts a proceeding involving the estate. Whether that step suits your situation depends on the facts, so it is worth raising with a lawyer.

Frequently asked questions

When does the six months start?

It runs from the grant of letters probate of the will or of letters of administration, not from the date of death.

What if the estate has not applied for probate yet?

The six-month period is tied to the grant. Whether you should act before then depends on your circumstances, so it is worth getting advice.

If I miss the deadline, is my claim over?

Not necessarily. The court may allow an application after six months, but only against the portion of the estate still undistributed on the application date.

Can a waiver I signed stop my claim?

Not always. A court can make a support order even if the dependant signed an agreement or waiver saying otherwise.
