Key takeaways
  • With a will, beneficiaries are those the will names; without one, the Succession Law Reform Act sets who inherits, generally the spouse and closest next of kin.
  • The person applying for probate must send or give the application to the estate beneficiaries before filing, so you may receive formal notice.
  • If your name differs from the records, a change of name certificate or marriage certificate helps connect the documents.
  • A person with a financial interest can ask to be notified of estate proceedings using Form 74P.

You believe you are entitled to something from an estate, but the estate trustee has asked you to prove it, or nobody has contacted you at all. You may be wondering which documents count and who decides.

In most cases the estate trustee is satisfied by a few straightforward records. This article explains what usually helps, and what to do if the answer is disputed.

Who counts as a beneficiary

If there is a will, the estate is normally distributed as the will directs once assets are liquidated and funeral costs and debts are paid. A beneficiary under a will is a person the will names to receive a gift.

Without a will, the Succession Law Reform Act sets who inherits. Generally that means the spouse and closest next of kin, and a common-law spouse does not inherit under that Act. Proving you are a beneficiary in that case means proving your family relationship to the deceased.

A surviving spouse also has a choice. They can elect an equalization payment under the Family Law Act instead of what the will or intestacy gives, and the Election of Surviving Spouse form must be filed no later than six months from the date of death.

Documents that usually help

What the estate trustee will accept depends on your situation. The list below shows the records people commonly gather. None of this replaces advice on your specific facts.

If you claim asDocuments that commonly help
Named in a willGovernment photo ID; a copy of the will showing your name and description
Child or parent of the deceasedYour birth record or the birth record showing the parent relationship; photo ID
Sibling, nephew or nieceBirth records that link each generation back to a common parent; photo ID
SpouseMarriage certificate; photo ID
Name has changedChange of name certificate or marriage certificate

An eligible legal name change through ServiceOntario costs $0 and produces a change of name certificate showing old and new names, usable to update documents. If you took a spouse's last name, you will need a marriage certificate, not the officiant's Record of Solemnization.

How the estate process confirms beneficiaries

An estate trustee is responsible for collecting assets, paying taxes and debts, and carrying out the will in line with the law. To get authority, the trustee usually applies for probate. With a will, the person usually applying is the named estate trustee.

Before filing, the applicant must send or give the application to the estate beneficiaries. The copy must be signed before a Commissioner for Taking Affidavits and can be sent by email to the last known address, by regular mail or by courier. For a small estate valued at $150,000 or less, the signed application goes to everyone entitled to a share at least 30 days before filing.

If a beneficiary is under 18, the Office of the Children's Lawyer must be served when applying for a certificate of appointment of estate trustee, and may act for that child.

What to do next

Frequently asked questions

What if I do not have a birth certificate?

Contact the estate trustee or its lawyer to ask what alternatives they will accept. A lawyer can advise on how to establish the relationship in your situation.

Does a common-law partner inherit without a will?

Under the Succession Law Reform Act, a common-law spouse does not inherit when there is no will. Other claims may exist, so ask a lawyer about your circumstances.

Will I be told if I am a beneficiary?

The person applying for probate must send or give the application to the estate beneficiaries before filing. If you have not heard anything, you can ask to be notified by using Form 74P.

Can I get court directions if the trustee will not cooperate?

A person who appears to have a financial interest in an estate may apply for directions under Rule 75.06. A lawyer can explain if this fits your case.
