Key takeaways
  • Ontario's Succession Law Reform Act sets the order of heirs when there is no will: spouse, issue, then parents, then brothers and sisters.
  • A common-law spouse does not inherit on an intestacy, though a dependant support claim may be available.
  • An estate trustee who cannot find an heir can ask the court for direction instead of distributing around them.

When someone dies without a will, the law decides who inherits. The first job is working out who those people are and whether they can be found.

This article explains how heirs are identified in Ontario, what tracing involves, and what commercial heir hunters generally do.

Who the heirs are under Ontario's rules

With no issue, the spouse takes everything. With issue, the spouse takes the preferential share and then one-half of the residue (one child) or one-third (two or more children). The rest goes equally among the issue. With no spouse or issue, the estate goes to the parents, then to brothers and sisters.

The spouse's preferential share is $350,000 for deaths on or after March 1, 2021, and $200,000 for deaths before that date.

There are important exceptions. A common-law spouse does not inherit under the Succession Law Reform Act when there is no will, and their remedy is a dependant support claim. Whether a separated spouse loses intestate entitlements can depend on when the person died and on how the Act defines separation, so it is worth confirming with a lawyer.

How estate trustees trace relatives

The estate trustee holds the property for the people entitled, subject to the deceased's debts. So the trustee needs a reliable picture of the family.

What heir hunters do

Heir hunters, also called probate genealogists, are private firms that research family trees to find people who may be entitled to an estate. They may contact a relative and offer to prove the claim in exchange for payment.

Contact from an heir hunter does not change who is entitled, and it does not change the estate trustee's duties. If you are approached, read any agreement carefully and have a lawyer review it before signing. You can also ask the estate trustee directly what you may be owed.

When an heir cannot be found

An estate trustee may apply to the Superior Court of Justice for the court's opinion, advice or direction without starting an action. This is the usual route for a beneficiary who cannot be found.

Advertising for creditors does not protect a trustee who distributes without a missing beneficiary's share. The protection a trustee gets from giving notice to creditors does not apply to heirs and next of kin claiming as such. When a judge passes final accounts and finds money belonging to a person whose address is unknown, it must be paid into court.

Dependants may also claim. If the deceased did not make adequate provision for a dependant's proper support, the court may order support from the estate. Once the estate trustee is served with notice of a support application, they must not distribute the estate unless all persons entitled to apply consent or the court orders it.

What to do next

Frequently asked questions

Who inherits when there is no will in Ontario?

It depends on the family. A spouse and issue share under a fixed formula, and with no spouse or issue the estate goes to the parents, then to brothers and sisters.

Does a common-law partner inherit without a will?

Not under the Succession Law Reform Act. Their remedy is a dependant support claim.

Is it safe to deal with an heir hunter?

Contact from an heir hunter does not change who is entitled. Read any agreement carefully and have a lawyer review it before you sign.

How long do I have to make a dependant support claim?

An application must be made within six months after letters probate or letters of administration are granted. The court may allow a later application against the part of the estate not yet distributed.
