Key takeaways
  • Who inherits on an intestacy depends on the statutory rules, and a stepchild's place in them should be confirmed with a lawyer rather than assumed.
  • Assets with a named beneficiary, such as insurance and registered plans, can pass to a stepchild outside the estate.
  • A dependant's support claim may reach assets that skip probate, and it generally must be made within six months of the grant.

Many blended families assume that a stepparent's children will be treated like the stepparent's own. When someone dies without a will, that assumption can cause real hardship, and surviving spouses and stepchildren often disagree about what is fair.

This article explains the practical routes by which a stepchild can receive something in Ontario, and what to confirm before relying on any of them. It does not replace advice on a specific family.

Intestacy rules decide, not family feeling

When there is no valid will, the law sets who inherits rather than the deceased's wishes. A stepchild's place in those rules depends on the family's situation, so it is worth confirming with a lawyer rather than assuming. Whether a stepchild has any statutory share depends on the rules that apply to the family, and a lawyer can confirm.

The surviving spouse's position can also change with the facts. The intestacy rules giving a spouse a share do not apply if the spouses were separated at the time of death, where the separation event happened on or after January 1, 2022. That can change who is left to inherit.

Assets that can reach a stepchild without a will

A stepparent can pass assets to a stepchild on death through named beneficiaries or joint ownership. Those assets sit outside the estate, so a missing will does not stop them.

If a stepchild is named on a registered plan, the plan administrator is discharged on paying the designated person, and that person may enforce payment. Insurance designations are governed by the Insurance Act instead, not by those plan rules. Check the actual forms rather than relying on memory.

A support claim may be an option

Ontario law lets a dependant of the deceased apply for support from the estate. For that claim, life insurance owned by the deceased and amounts payable under a plan designation are deemed part of the net estate, so designated assets can still be reached by a dependant.

There is a deadline. A dependant's support application generally cannot be made more than six months after the grant of letters probate or administration. The court may allow a later application against any part of the estate that is still undistributed. Whether a particular stepchild qualifies as a dependant depends on the facts of the family, so it is worth raising with a lawyer promptly.

Frequently asked questions

Are stepchildren automatically heirs in Ontario?

It should not be assumed. A stepchild's position depends on the facts of the family, so it is worth confirming with a lawyer. Naming the stepchild as a beneficiary on insurance or a registered plan is one way assets can pass to them outside the estate.

Can a stepparent leave a stepchild insurance money?

Yes, by naming the stepchild as a beneficiary in the contract or by a declaration. The money then does not form part of the estate.

Can a stepchild make a support claim?

Possibly, if they qualify as a dependant, which depends on the facts. Designated insurance and plan amounts are deemed part of the net estate for that claim.

How long do I have to act?

A dependant's support application generally cannot be made more than six months after the grant of letters probate or administration, though the court may allow a later application against undistributed estate property.
