Key takeaways
  • A child conceived before the parent's death and born alive afterward counts as a child and as issue for intestacy.
  • That child is treated as if born in the deceased's lifetime, and the right to inherit starts on the day of birth.
  • A child conceived and born after the death is treated as a child only if strict conditions are met.
  • A common-law partner is not a spouse for intestacy, though a support claim may still be possible.

If your partner died while you were pregnant, you may be facing grief and a very practical question at once: will the baby be treated as a child of the person who died? In Ontario the answer, for a child conceived before the death, is generally yes.

This article explains how the Succession Law Reform Act treats a child born after a parent's death when there is no will, how that affects a spouse's share, and what changes if the partners were not married. It is general information, and the details of an estate are worth confirming with a lawyer.

A child conceived before death and born afterward

The Act defines child and issue to include a child conceived before the parent's death and born alive afterward. Its inheritance rules then treat such descendants as if they had been born in the deceased's lifetime, with the right to inherit starting on the day of birth.

In practice, this means the unborn child is counted among the deceased's issue when working out who takes. The word alive matters: the rule covers a child born alive, so the position is settled only once the birth has occurred.

How the child's presence changes the shares

Whether there is a surviving spouse is the main factor. The table shows how the child fits in once counted as issue.

SituationHow the estate divides
Married spouse survives, child is the only issueIf the net value of the intestate estate is no more than the preferential share, the spouse takes all of it; if more, the spouse takes the preferential share first. The preferential share is $350,000 for deaths on or after March 1, 2021. The spouse then takes one-half of the residue and the child the rest, since the spouse has one child.
Married spouse survives, more than one childAfter the preferential share, the spouse takes one-third of the residue and the rest goes to the issue.
No spouse survivesThe estate goes equally to the issue in the nearest degree.

Net value means the value after charges on the property, debts, funeral expenses and administration expenses. Property that passes by right of survivorship, such as a jointly owned home, falls outside the estate.

If you and your partner were not married

A common-law partner is not a spouse for the intestacy rules, because spouse in that part of the Act has the Family Law Act meaning, which covers married persons. A partner who was never married to the deceased therefore does not inherit as a spouse. The child, however, is still the deceased's issue and takes under the rules above.

A common-law partner may still apply for dependants' support from the estate, whether or not there is a will, if the deceased did not make adequate provision for proper support. A support application generally cannot be made more than six months after the grant of letters probate or letters of administration, though the court may allow a late application for any part of the estate still undistributed.

Spousal entitlements also do not apply if the spouses were separated at death, as the Act defines separation. If that might describe your situation, get advice early.

A child conceived after the death

A different rule applies where a child is both conceived and born after the parent's death. That child is treated as a child of the deceased only if every one of these conditions is met:

The six-month notice deadline is short. Anyone in this position should speak with a lawyer promptly.

Court steps and protection for a minor

When a child is a beneficiary, the court process includes extra protection. The applicant for a certificate of appointment must serve every person entitled to share in the estate; for a minor, that means a parent or guardian and the Children's Lawyer, and for unborn or unascertained beneficiaries, also the Children's Lawyer. 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.

Ontario.ca advises obtaining the certificate of appointment before anyone enters into an agreement of purchase and sale for the deceased's real property. That can affect timing if a home is involved.

What to do next

Frequently asked questions

Will my baby inherit if the baby is born after the other parent dies?

If the child was conceived before the death and is born alive afterward, the child counts as a child and issue of the deceased. The child is treated as if born in the deceased's lifetime, and the right to inherit starts on the day of birth.

Can I get anything if we were common-law partners?

A common-law partner is not a spouse for intestacy, so you would not inherit under those rules. You may be able to apply for dependants' support from the estate.

Who looks after the child's inheritance?

The Children's Lawyer must be served for a minor beneficiary. A child's inheritance over $35,000 is paid into court and held by the Accountant of the Superior Court of Justice, or a court-appointed guardian of property.

What if the child is conceived after the death?

The child counts only if written notice goes to the Estate Registrar within six months of the death, the child is born within the time limit, and a court declaration of parentage is made. Legal advice is wise because the time limits are short.
