Key takeaways
  • Estate assets are distributed depending on how they are owned, and Ontario lists jointly owned money as an example.
  • Assets that automatically become the other owner's are left out of the value used for Estate Administration Tax.
  • On a gratuitous transfer, the court decides the transferor's actual intention, starting with the applicable presumption.
  • Evidence of intent must relate to the time of the transfer, and courts guard against self-serving evidence.

When one person who held a joint bank account dies, the survivor often wants to know two things: can I keep the money, and could the estate or other family members claim it? The answer depends on how the account is held and on what the account holder intended when it was opened or funded.

This article explains the general approach in Ontario and the kind of proof that tends to matter. It is not advice on your situation, and disputes over accounts are worth taking to a lawyer early.

Does the survivor automatically keep the account?

Ontario says the assets in an estate are distributed depending on how they are owned. It lists money and property jointly owned with another person as examples. Where an asset is jointly owned and automatically becomes the other owner's asset, it is excluded from the estate value used to calculate Estate Administration Tax.

The survivorship rule is clearest for land, where a joint tenant's interest automatically passes to the surviving owner. For bank accounts, the answer can depend on the details of how the account was set up and why. That is where disputes can arise, and a lawyer can confirm how the rules apply to your account.

Why an estate might claim the money

Sometimes money is placed in joint names for convenience, such as so a family member can pay bills. If the owner never meant the other person to keep what was left, the estate or the other beneficiaries may argue the money belongs to the estate.

Ontario's courts approach this by looking at the transferor's actual intention. On a gratuitous transfer, meaning one made without payment, the transferee has the onus to show a gift was intended. The judge starts with the applicable presumption and decides the transferor's actual intention on a balance of probabilities.

The Court of Appeal has also held that a trial judge erred by putting the onus on the transferee when property was jointly registered, instead of starting with the presumption of resulting trust. A resulting trust means, in simple terms, that the property is treated as still belonging to the person who provided it. Which presumption applies in a particular case is a point to confirm with a lawyer.

What proof of intent can matter

Courts treat evidence from the surviving owner after the death with care. Evidence of intention must relate to the transferor's intention at the time of the transfer, and courts must guard against evidence that is self-serving or reflects a change in intention.

How the paperwork usually unfolds

Banks often ask for proof of death and, in some cases, proof of authority before they release or change accounts. Ontario notes that an institution demanding proof of authority is one trigger for applying for probate. Whether a particular bank will release a joint account to the survivor without it is a question for the bank.

SituationWhat generally follows
Account clearly passes to the survivor and no one disputes itIt is treated as outside the estate for Estate Administration Tax
Family member says the money was only held for convenienceCourt looks at the owner's actual intention on a balance of probabilities
Estate is valued at $50,000 or lessNo Estate Administration Tax, but the return must still be filed
Estate is largerTax is $15 for every $1,000 or part over $50,000

If a certificate is needed, the tax is due the day the estate certificate is issued, and an Estate Information Return is due within 180 calendar days of issue, even if the estate is worth $0.

What to do next

Frequently asked questions

Can the estate claim money in a joint account?

It may be able to, depending on the facts. A court looks at the transferor's actual intention, and on a gratuitous transfer it starts with the applicable presumption. A lawyer can tell you which presumption is likely to apply.

Is a joint account part of the estate for Estate Administration Tax?

The tax excludes joint-ownership assets that automatically become the other owner's assets. If an account is found to belong to the estate, it may count toward the estate's value.

Does the survivor's later explanation of what the owner wanted settle it?

Not on its own. Evidence must relate to the owner's intention when the transfer was made, and courts guard against self-serving evidence.

Do I need probate to deal with a joint account?

It depends on the bank and on the other assets. Ontario says probate is normally required if the deceased owned real property or assets held by a financial institution, and an institution demanding proof of authority is a trigger.
