Key takeaways
  • Ontario's intestacy rules list a spouse and the deceased's own descendants, parents and other relatives, and stepchildren do not appear in that order.
  • If the deceased leaves a spouse and no children of their own, the spouse takes the whole intestate estate, even if there are stepchildren.
  • A stepchild the deceased showed a settled intention to treat as a child may be able to apply for dependants' support, usually within six months of the grant.
  • Common-law partners do not inherit on an intestacy, although they may still claim support.

Second marriages are common, and so are households where one spouse has children from an earlier relationship. If one spouse dies without a will, Ontario does not look at who the family thought of as family. It applies a fixed set of rules based on legal relationships.

Those rules can produce results that surprise blended families. This article explains how the spouse and the deceased's own children share an estate, where stepchildren stand, and what other claims may be open. It is general information, not advice on your situation.

How the intestacy rules divide an estate

When someone dies without a valid will, the Succession Law Reform Act sets who inherits. The answer depends mainly on whether the deceased left a spouse and whether they left children or other descendants, which the Act calls issue.

Who survivesWhat the rules provide
Spouse, no issueThe spouse takes the whole intestate estate.
Spouse and one childThe spouse takes the preferential share first, then one-half of the rest; the remainder goes to the child.
Spouse and more than one childThe spouse takes the preferential share first, then one-third of the rest; the remainder goes to the issue.
No spouse, but issueThe estate goes equally to the issue in the nearest degree.

The preferential share is $350,000 for people who die on or after March 1, 2021, and was $200,000 for earlier deaths. If the net estate is no more than the preferential share and there is a spouse and issue, the spouse takes all of it. Net value is worked out after charges on the property, debts, funeral expenses and administration expenses.

Why this matters for children of an earlier relationship

Picture a parent with two children from a first relationship who remarries and dies without a will. The new spouse takes the preferential share and then a one-third share of what is left, and the children share the remainder. The children are not cut out, but the spouse takes a large first slice, and in a small or modest estate the spouse may take all of it.

The bigger risk is what happens next. Whatever the spouse receives becomes the spouse's own property. If the spouse later dies, it passes under the spouse's own will or intestacy, and nothing in the first spouse's estate guarantees it ends up with the first spouse's children. That is a general consequence of how ownership works, and it is worth raising with a lawyer if you are concerned.

Where stepchildren fit

The order of heirs on an intestacy runs through the spouse, issue, parents, siblings, nieces and nephews, and then more distant next of kin. Stepchildren are not named anywhere in that order. If the deceased left a spouse and no children of their own, the spouse takes everything, and the stepchildren take nothing from the estate as of right.

Stepchildren may have another route. Under Part V of the Act, a court may order support from an estate if the deceased did not make adequate provision for the proper support of a dependant, whether or not there was a will. A dependant can include a child, and for this purpose a child includes a person the deceased showed a settled intention to treat as a child. Whether a particular stepchild qualifies depends on the facts, including whether the deceased was providing or obliged to provide support immediately before death.

Courts look at things such as the dependant's assets and means and their accustomed standard of living. Need is assessed as of the hearing date. An application generally cannot be made more than six months after the grant of probate or letters of administration, although a court may allow a late application for any part of the estate still undistributed.

Other rules that change the picture

The equalization choice can shift results in either direction depending on each spouse's net family property, so a spouse and any affected children benefit from understanding the numbers before the six-month window closes.

Minor children, conflicts and who runs the estate

Where a child is a beneficiary on an intestacy, the Office of the Children's Lawyer must be served on the application. With no will, the child receives their share at 18, and a child's inheritance over $35,000 is paid into court and held by the Accountant of the Superior Court of Justice, or by a court-appointed guardian of property, rather than by the estate trustee.

On a no-will estate, the deceased's spouse or common-law partner usually has the first right to apply to administer the estate, and if they do not, a close adult relative such as a child, parent, grandchild, sibling, niece or nephew can apply, with the court choosing the most suitable. The court may commit administration to the spouse, the next of kin, or both, as it sees best. In a blended family this can create tension, because the person with priority may not be the person the children would choose.

An administrator generally gives a bond, though a judge can reduce or dispense with it, and it is generally not required for a small estate unless a beneficiary is a minor. Rules of court also allow a person to object to a certificate being issued, ask for directions, or seek revocation of a certificate.

What to do next

Frequently asked questions

Do stepchildren inherit if their stepparent dies without a will in Ontario?

Not under the intestacy order, which lists the spouse, issue, parents, siblings and more distant relatives. A stepchild may be able to apply for dependants' support if the deceased showed a settled intention to treat them as a child.

If my spouse dies with no will, do my children from my first marriage get anything?

If you have children and a spouse, the spouse takes the preferential share and then a fraction of the rest, and the remainder goes to the children. If the net estate is no more than the preferential share, the spouse takes it all.

Does my common-law partner inherit if I die without a will?

No. A common-law partner is not a spouse for intestacy purposes. They may still be able to claim dependants' support, and may have the first right to apply to administer the estate.

How long do I have to make a support claim against an estate?

A support application generally cannot be made more than six months after the grant of probate or letters of administration. A court may allow a late application for any part of the estate that has not yet been distributed.
