Key takeaways
  • Property that passes by survivorship goes straight to the surviving owner and not into the estate, whether or not there is a will.
  • When an adult child is added to a parent's account without paying for it, the child is presumed to hold the money in trust for the parent and, on death, for the estate.
  • Between spouses, money on deposit in both names is deemed held as joint tenants, so the usual starting point is different.

A parent or spouse has died, and a bank account was in two names. The survivor may think the money is theirs. Other family members may say it belongs in the estate. Both positions can be argued, and the answer is not decided by the name on the account alone.

This article explains how Ontario treats joint accounts after a death, how the presumption of resulting trust works, and what evidence matters. It is general information, not advice on your situation.

Two possible outcomes: survivorship or estate

Many joint accounts carry a right of survivorship. If so, the surviving holder becomes the account owner.

Property that passes by survivorship goes directly to the surviving owner and does not go into the estate, whether or not there is a will. A will cannot redirect it, because the rule that sends property to the estate trustee applies only to property with no right of survivorship attached.

The dispute usually is not about whether survivorship exists in the bank's paperwork. It is about whether the deceased truly meant the survivor to keep the money, or only put the survivor's name on the account for convenience.

The presumption of resulting trust for adult children

For gratuitous transfers, meaning transfers where nothing was paid, the presumption of resulting trust is the general rule. The person who receives the transfer must show that a gift was intended.

In practice, an adult child added to a parent's account without paying anything is presumed to hold it in trust for the parent and, on death, for the estate. The presumption of advancement, which treats a transfer as a gift, is confined to minor children. An adult child's financial dependency does not trigger it, though it can be strong evidence against a resulting trust.

The survivorship interest is treated as a gift made during the parent's life, made when the account is opened. What is gifted is the survivor's interest in the balance at the time of death.

Spouses are treated differently

Between spouses, the resulting trust presumption applies as if they were not married, with two exceptions. Property held in both spouses' names as joint tenants is proof, without evidence to the contrary, that they intended to own it as joint tenants. Money on deposit in both spouses' names is deemed held as joint tenants.

A surviving married spouse may also elect equalization of net family property. Property the survivor receives by right of survivorship is credited against that entitlement. The credit does not apply if a written instrument says the survivor receives the property in addition to the equalization entitlement. Unmarried partners cannot elect equalization.

What evidence can decide the question

Courts can look at several kinds of evidence about what the deceased intended when the account was set up:

Heirs may challenge the survivor, who may then need to show the deceased meant the funds as a gift.

Frequently asked questions

Does a joint account automatically go to the survivor in Ontario?

Not always. Many joint accounts include a right of survivorship, and the survivor becomes the owner. But heirs may challenge the survivor, who may need to show the deceased intended the funds as a gift.

Can a will leave a joint account to someone else?

Generally not for property that passes by survivorship. That property goes to the surviving owner, not to the will's beneficiaries.

Is a spouse treated the same as an adult child on a joint account?

No. Money on deposit in both spouses' names is deemed held as joint tenants. An adult child added without payment is presumed to hold the money in trust for the parent.

Does a joint account avoid estate administration tax?

Jointly owned property that passes automatically to the other owner is not counted. A joint asset the survivor holds on resulting trust for the estate does not escape the tax.
