Key takeaways
  • For gratuitous transfers, the presumption of resulting trust is the general rule, so the transferee must show a gift was intended.
  • For an adult child on a parent's joint account, the survivor must prove the parent intended to give the right of survivorship.
  • Intent is judged at the time of the transfer, on a balance of probabilities.
  • Estate Administration Tax is charged on the value of the estate as of the date of death.

A joint bank account looks simple: two names on the account, so the survivor keeps the money. In estates, the question is often harder. A parent may have added an adult child only for convenience, to help pay bills, and other children may expect the money to be shared under the will.

This article explains the basic idea of survivorship, how the Supreme Court of Canada approached the presumption of resulting trust, and what an executor should do when the account's ownership is unclear. Because these disputes turn on the facts, legal advice is often worthwhile.

Survivorship and why it matters to the estate

Right of survivorship is the idea that a surviving joint owner may take an asset directly, instead of it passing under the will. Whether that applies to a particular account depends on the facts, so it is worth confirming with a lawyer.

An executor needs to know who really owns an account, because that affects what the estate has to deal with. How this applies depends on your situation, so it is worth confirming with a lawyer. The estate trustee's job is to collect the deceased's assets, pay debts and distribute the residue.

The same idea applies to land. Real property that does not pass by right of survivorship generally needs probate. So both bank accounts and real estate raise the question of whether the asset belongs to the survivor or to the estate.

The label on the account is not always the end of the question. When the dispute is about what the deceased actually intended, the court looks at the evidence.

The presumption of resulting trust

In Pecore v. Pecore, 2007 SCC 17, the Supreme Court of Canada said the presumption of resulting trust is the general rule for gratuitous transfers. That means the person receiving the transfer must show a gift was intended.

The test for rebutting the presumption is the transferor's contrary intention, on a balance of probabilities, judged at the time of the transfer. What the deceased intended when the account was opened or changed is what matters, not what people wish had been intended later.

For an adult child on a parent's joint account, the presumption of resulting trust applies, and the surviving child must prove the parent intended to give the right of survivorship. What that means for a particular account depends on the evidence, so it is worth confirming with a lawyer.

Evidence that tends to matter

Since intent is the heart of the question, executors and survivors should collect documents early. What counts as strong or weak evidence depends on the facts, and a lawyer can assess it.

Possible evidenceWhy it may help
Account opening documents and any signed formsShow how the account was set up and what was recorded at the time
Who deposited and who withdrewHelps show whether the account was for convenience or shared ownership
Statements over several yearsShow how the account was actually used

Keep records safe. Estate representatives must keep the records supporting the Estate Information Return for four years.

Estate tax and reporting

Estate Administration Tax is charged on the value of the estate as of the date of death. The return must report the total value of real property and personal property owned by the deceased at death. Whether a joint account counts toward that value depends on whether it was truly the deceased's property, which is the same ownership question described above.

For estates where the certificate application was made on or after January 1, 2020, there is no tax if the estate is worth $50,000 or less. Above that, the tax is $15 for every $1,000, or part, of estate value. The initial Estate Information Return is due within 180 calendar days after the certificate is issued.

Getting the value wrong has consequences. The Ministry may assess or reassess within four years after the tax was due, with no time limit where a filing was missed or a misrepresentation was made. False or misleading statements on the return can bring a fine of at least $1,000 and up to twice the tax payable, up to two years' imprisonment, or both. If you are unsure whether an account belongs on the return, get advice before filing.

What to do next

Frequently asked questions

Does the surviving joint holder always keep the money?

Not always. Where an adult child is on a parent's joint account, the presumption of resulting trust applies and the survivor must prove the parent intended to give the right of survivorship. The outcome depends on the evidence.

What does 'balance of probabilities' mean here?

It means it is more likely than not that the deceased had the intention in question. The intention is judged at the time of the transfer.

Is a joint account counted when the estate tax is calculated?

The tax is charged on the value of the estate at the date of death, based on property the deceased owned. Whether a particular joint account counts depends on who truly owned the money, so confirm this with a lawyer or accountant.

What should an executor do if the family disagrees about an account?

Gather the account records, avoid distributing disputed funds and get legal advice. If accounts are later reviewed by the court, interested persons can serve a notice of objection when the estate trustee applies to pass accounts.
