Adding a Child to Your Bank Account: What Happens to It When You Die?

Adding a son or daughter to your bank account can make life easier. They can pay bills if you are unwell, and many people assume the money will simply go to that child when they die, without probate.

Sometimes it does. But the law looks at what you actually intended, and if that is unclear the money may end up in your estate instead, or become the subject of a dispute between your children. This article explains how joint accounts work from a parent's point of view and what you can do now to make sure the account passes the way you want.

Why parents add a child to an account

Parents usually have one of three goals in mind, and it helps to be honest with yourself about which one is yours:

• Convenience. You want a child to help with banking now, and you expect the money to be shared under your will when you die.
• A gift on death. You want that child to receive whatever is left in the account when you die, outside your will.
• A gift now. You intend the child to own part of the money immediately.

The bank's paperwork rarely captures this. That gap is where most problems start.

Survivorship and the question of intention

Most joint accounts are opened with a right of survivorship. When one holder dies, the bank lets the surviving holder take the funds. That deals with who can withdraw the money. It does not finally settle who is entitled to keep it.

In Pecore v. Pecore, 2007 SCC 17, the Supreme Court of Canada considered who is entitled to joint bank and investment accounts after the death of the person who contributed the money. The Court confirmed that the general rule for a transfer made for nothing in return is a presumption of resulting trust, with a separate presumption of a gift applying only in some relationships. Where the resulting trust presumption applies and the evidence is unclear, the child is presumed to hold the money for the parent, and after the parent's death for the estate. The surviving joint holder has to prove that the parent intended to give them the right of survivorship.

The Court also said bank documents can be strong evidence of intention, and that evidence from after the account was opened may be considered, with care taken about self-serving statements. In practice, this means the outcome depends on the evidence available after you have died, when you can no longer explain what you meant.

What happens to the account when you die

If the court finds you intended a gift

The child keeps the balance. The money passes outside your will and does not form part of your estate. That generally means it is not counted when probate fees are calculated, and a claim under the Wills, Estates and Succession Act to vary a will, which is a claim against the estate, will not usually reach it. Our article on probate fees in BC explains how those fees are worked out.

If the court finds the child held it in trust

The child must hand the money over to your executor, and it is shared under your will (or the intestacy rules if you have no will). Probate fees may apply to it, and it is available to all your beneficiaries.

Either outcome can be what you want. The problem is uncertainty. When the paperwork is unclear and siblings disagree, families can end up in a costly dispute, often while they are still grieving.

Fairness to your other children

If you have more than one child, adding just one to a large account can unintentionally upset an equal plan in your will. Your will might divide everything equally, but if most of your savings sit in a joint account that passes to one child by survivorship, the others may receive far less than you expected.

Sometimes that is deliberate, for example to recognise a child who has been your caregiver. If so, say so clearly in writing. If it is not deliberate, consider whether a joint account is the right tool at all. The same issues arise with real estate, which we discuss in our article on adding a child to title.

Risks while you are alive

A joint account also carries risks during your lifetime:

• Access. A joint holder can usually withdraw funds without your consent.
• The child's problems. A child's creditors, separation or bankruptcy may create claims or complications involving the account.
• Tax reporting. The Canada Revenue Agency says certain bare trust arrangements may have to file a T3 return for tax years ending on or after December 31, 2026. Its guidance excludes, for example, a joint bank account held by family members for the use and benefit of each of them, but an account where the child holds money only for the parent may be treated differently, and other exceptions can apply. Confirm the current CRA guidance with your accountant before year end.

If your main goal is help with banking, a power of attorney may give a trusted child authority to manage your money without making them a joint owner. See our guide to powers of attorney and representation agreements.

How to document what you intend

The most useful step is to leave clear evidence of your intention, made at the time, that does not depend on anyone's memory. Depending on your goals, that can include:

• A signed declaration or memorandum stating whether the child is to keep the balance on your death or hold it for your estate, ideally prepared with a lawyer and kept with your will.
• Consistent wording in your will so the will and the account point in the same direction.
• A conversation with your children so nobody is surprised.
• A regular review after major changes, such as a child's separation, a large deposit, or a decision to move savings into the joint account.
