Key takeaways
  • Nieces and nephews inherit only if there is no spouse, issue, parent, brother or sister, and they share equally without anyone taking a deceased niece's or nephew's place.
  • If no niece or nephew survives, the estate goes to the next of kin of equal degree, which can include cousins.
  • Only an estate trustee has legal authority to deal with the estate, and on an intestacy a bond is generally required.

When someone dies without a valid will and leaves no spouse, children or parents, the family tree can feel wide open. You may be a niece, nephew, grand-niece or cousin wondering whether you are entitled to anything, or whether the estate simply goes to the government.

Ontario's Succession Law Reform Act sets out a fixed order of who inherits when there is no will. This article walks through the part of that order that reaches further-out relatives, and then explains who can apply to administer the estate.

Where nieces, nephews and cousins fit in the order

On an intestacy, the people who can inherit are the deceased's spouse and closest next of kin. Each group in the order is considered only if the group before it is empty. Nieces, nephews and cousins come near the end of that order, so they inherit only when there is no one above them.

OrderWho inheritsCan a deceased person's children take their place?
1Spouse and children, in the shares set by the ActYes, grandchildren take a deceased parent's share
2Parents equally, or the surviving parentNot stated for this step
3Brothers and sisters equallyYes, a deceased sibling's children share their parent's portion
4Nephews and nieces equallyNo, without representation
5Next of kin of equal degree, such as cousinsNo, without representation

Two points about the people at the top of the order matter here. A common-law spouse does not inherit under the Succession Law Reform Act when there is no will. And married spouses who were separated at the time of death, as the Act defines separation, do not take the spouse's entitlements, but this rule applies only where the qualifying separation event happened on or after January 1, 2022. In either case, the estate may reach more distant relatives sooner than you would expect.

Siblings first, then nieces and nephews

If there is no spouse, issue or parent, the estate goes to the surviving brothers and sisters equally. A brother or sister who died before the deceased does not simply drop out. That sibling's share goes equally to their children, who are the deceased's nieces and nephews.

Only if there is no spouse, issue, parent, brother or sister does the estate go equally to the nephews and nieces. This step works "without representation". The children of a niece or nephew who has died do not take that person's share. How this applies to a particular family depends on the facts, so it is worth confirming with a lawyer.

Cousins and other next of kin

If there is no spouse, issue, parent, brother, sister, nephew or niece, the estate goes equally to the next of kin of equal degree of consanguinity, again without representation.

Degrees of kinship are counted up from the deceased to the nearest common ancestor and then down to the relative. How the count works out for a particular family tree is worth confirming with a lawyer.

What if no relatives can be found?

If there is no surviving spouse, issue, parent, brother, sister, nephew, niece or next of kin, the property becomes the property of the Crown and the Escheats Act, 2015 applies. The Public Guardian and Trustee may take possession of it in the name of the Crown.

That is not always the end of the matter. A person who proves a legal claim to escheated property to the satisfaction of the Public Guardian and Trustee is entitled to receive it, which covers a lawful heir located later. The Lieutenant Governor in Council may also, by order, grant escheated property to a person with a moral claim on the deceased.

Who can administer the estate, and what to do next

Inheriting and administering are different things. The estate trustee is the only person with legal authority to manage or distribute an estate, and the court's certificate gives that authority. Without a will, administration may be granted to the spouse or a person in a conjugal relationship with the deceased, to the next of kin, or to both. After a spouse or common-law partner, a close adult relative such as a sibling or nephew or niece can apply, and the court may appoint the relative it considers most appropriate.

A bond is required when the deceased died without a will. It is for double the sworn value of the property, unless a judge orders otherwise.

There are limited exceptions. The surviving-spouse exemption applies only where there is a spouse, so it will not help in a case like the one in this article. A small estate needs no bond unless a beneficiary is a minor or is incapable under the Substitute Decisions Act, 1992. A judge may also reduce or dispense with the bond in special circumstances.

Frequently asked questions

Do cousins inherit if there is no will in Ontario?

They can, but only when there is no spouse, issue, parent, brother, sister, nephew or niece. The estate then goes equally to the next of kin of equal degree, without representation. Degrees are counted up to the nearest common ancestor and down to the relative.

If my parent was a niece who died before the deceased, do I take her share?

Not at the niece and nephew stage. That step works without representation, so the children of a deceased niece or nephew do not take that person's share. The result differs for the child of a deceased sibling, who does take the sibling's share.

Do half-siblings or adopted relatives count?

Half-blood relatives inherit equally with whole-blood relatives of the same degree. An adopted child is treated as the child of the adoptive parent from the adoption order and stops being the child of the former parent, except where that person is the adoptive parent's spouse. So birth-family relationships generally no longer count after an adoption.

Can I deal with the estate myself as a nephew or niece?

Not until you are appointed. The estate trustee is the only person with legal authority to manage or distribute an estate. A niece or nephew may be able to apply, and the court may appoint the relative it considers most appropriate.
