Key takeaways
  • A common-law partner does not inherit under Ontario's intestacy rules when there is no will.
  • You may still have a priority right to apply to administer the estate, and you may be able to ask the court for support as a dependant.
  • A support application cannot be made after six months from the grant of letters probate or letters of administration, with limited exceptions.

Losing your partner is hard enough. Learning that they left no will, and that you were never married, can add a second shock: the law may not treat you the way you expected.

This article explains where you stand in Ontario. You do not receive an automatic share, but you may have two other routes: applying to manage the estate, and asking the court for support. It also explains who inherits in your place, and the deadlines to watch.

Why you do not inherit automatically

When someone dies without a valid will, Ontario's Succession Law Reform Act decides who inherits, and the people who can inherit are the deceased's spouse and closest next-of-kin. For these rules, "spouse" has the meaning in section 1 of the Family Law Act, which covers people who are married to each other.

The result is that a common-law spouse does not inherit under the Succession Law Reform Act when there is no will. The law does give unmarried partners other rights, described below.

Route one: applying to administer the estate

Someone has to be appointed to manage the estate. The estate trustee is the only person with legal authority to manage or distribute it, and the court's certificate gives the authority to manage estate assets and pay estate debts.

On an intestacy, administration may be granted to the person the deceased was married to immediately before death, or a person living with the deceased in a conjugal relationship outside marriage immediately before death, or to the next of kin, or to both. In practice, the spouse or common-law partner usually has the first right to apply, and close adult relatives such as a child, parent, grandchild, sibling or nephew or niece can apply after them.

This right is not absolute. The court is not obliged to grant administration to the person otherwise entitled, and where necessary or convenient it may appoint anyone it thinks fit, on security the court directs.

Being appointed does not make you an heir. It gives you the job of managing the estate for the people who are entitled to it.

Route two: a dependant support claim

Part V of the Succession Law Reform Act lets a dependant apply to court for support from the estate if the deceased did not make adequate provision for them. For this Part, "spouse" takes the meaning in section 29 of the Family Law Act.

Under that section, unmarried partners count as spouses if they cohabited continuously for at least three years, or were in a relationship of some permanence and are the parents of a child. Whether you qualify, and what support would be adequate, depends on your facts, so this is a point to review with a lawyer.

The six-month deadline and the freeze on distribution

A dependant's support application cannot be made after six months from the grant of letters probate or letters of administration. The clock runs from the grant, not from the date of death, so a grant that is issued months after the death moves your deadline later.

There is an exception. The court may allow an application at any time for any part of the estate still undistributed on the date of the application.

Once the personal representative has been served with notice of a support application, they must not distribute the estate until the court has disposed of it, unless everyone entitled to apply consents or the court orders otherwise.

Who inherits in your place

Because you are not a spouse for intestacy purposes, the estate goes to the deceased's family under the statutory order. The estate moves down the list below only when no one in the earlier group survives.

If the deceased was still legally married to someone else, that person may count as the spouse. An exception applies if the spouses were separated within the meaning of the Act at the time of death, but only where the qualifying event, such as three years living apart or a separation agreement, happened on or after January 1, 2022. A lawyer can help confirm which applies.

What to do next

Frequently asked questions

Does a common-law partner inherit anything if there is no will in Ontario?

Not under the intestacy rules, because a common-law spouse does not inherit under the Succession Law Reform Act when there is no will. You may still apply to court for support as a dependant if you meet the test.

How long do I have to make a support claim?

The application cannot be made after six months from the grant of letters probate or letters of administration. The court may allow a late application for any part of the estate still undistributed on the date of the application.

Can I be the estate administrator if we were not married?

A person living with the deceased in a conjugal relationship outside marriage immediately before death is among those who may be granted administration. The court is not obliged to grant administration to the person otherwise entitled, and where necessary or convenient, for example because of insolvency or other special circumstances, it may appoint anyone it thinks fit, on security the court directs.

Can the estate be distributed while my claim is pending?

Once the personal representative has been served with notice of your application, they must not distribute the estate until the court has disposed of it, unless everyone entitled to apply consents or the court orders otherwise.
