Key takeaways
  • Being named on a parent's account does not by itself settle whether the balance is yours or the estate's.
  • A joint account is one of the ways assets can pass outside the will, but the parent's actual intention at the time can still be examined.
  • The person who received the money may have to show that a gift was intended.
  • Money that passes automatically to a joint owner is left out of the estate value for Estate Administration Tax.

Many adult children are added to a parent's bank account so they can pay bills, buy groceries or deal with the bank when the parent is unwell. The parent never meant to give them the money. Then the parent dies, the bank says the account is now yours, and the other family members say it belongs to the estate.

This article explains in plain language how Ontario treats that situation. The answer depends on facts, and some questions are not covered here, so treat this as a map of the issues. A lawyer can tell you how they apply to your account.

Why the bank may treat the account as yours

Ontario's government lists money and property that is jointly owned with another person as one of the kinds of assets that are distributed depending on how they are owned, and gives a joint bank account as an example of a designated-beneficiary type asset. In other words, a joint account can pass outside the estate on death.

The general rule behind this is the right of survivorship. It applies only to interests held in a joint tenancy, and property that does not pass by survivorship goes to the deceased's personal representative. If the account really was a joint holding, the bank may release it to you without involving the estate.

That is not the end of the question. How an account is registered shows how it is held on paper. It does not necessarily show what your parent meant when they added your name.

The real question: what did your parent intend?

When someone puts property into joint names without receiving anything in return, the person who received it has the onus of showing that a gift was intended. A judge starts with the applicable presumption and then decides the transferor's actual intention on a balance of probabilities.

The Court of Appeal for Ontario has also said a trial judge made an error by putting the onus on the person who received the property when it was jointly registered, instead of starting with the presumption of resulting trust. A resulting trust, in simple terms, means the property is treated as held for the person who put it in, and so for their estate. That decision concerned jointly registered property, so a lawyer should confirm how it applies to a bank account like yours.

Evidence of your parent's wishes after the transfer can be considered only if it relates to their intention at the time of the transfer. Courts must also guard against evidence that is self-serving or reflects a later change in intention.

Evidence that tends to matter

What counts as good evidence depends on your facts, so the examples below are practical ideas rather than legal tests.

Question a court may askRecords or evidence you might gather
Why was your name added?Bank account-opening forms, notes, emails or messages from around that time
How was the account used?Statements showing whether money went to your parent's bills and care or to your own use
Who dealt with the money and tax?Records of who reported the account's income and who made decisions
What did your parent say, and when?Statements to advisers or family made at the time the name was added, not later

Keep in mind that your own after-the-fact account of what your parent wanted can be treated with caution, because courts must guard against self-serving evidence. Independent records made at the time generally carry more weight than recollections.

What it means for the estate, probate and tax

Estate Administration Tax leaves out of the estate's value assets under joint ownership that automatically become assets of the other owners. For estate certificates applied for on or after January 1, 2020, the tax is $15 for every $1,000 (or part of $1,000) of estate value over $50,000. So whether the account is treated as the estate's can change the tax bill.

If the estate trustee takes the position that the account was held only for convenience, the money would be an estate asset and would count towards that value. Ontario also says probate is normally required if the deceased held assets at a financial institution, and disputes are one of the triggers for applying.

What to do next

Frequently asked questions

If my name is on the account, does the money automatically belong to me?

Not necessarily. The right of survivorship applies to joint holdings, but a court asks what the parent actually intended when your name was added, and the person who received the money may have to show a gift was meant.

Who has to prove the account was only for convenience?

For a gratuitous transfer, the person who received the property has the onus to show a gift was intended, and the judge starts with the applicable presumption. How that works for your specific account is something a lawyer can confirm.

Does the account count in the value of the estate for probate tax?

Assets under joint ownership that automatically become the other owner's are excluded from the estate's value for Estate Administration Tax. If the account is found to belong to the estate, it would be part of the estate instead.

Can I keep using the account after my parent dies?

You should be cautious. Because ownership may be disputed, withdrawing money could cause problems later. Get advice before making any withdrawals.
