If you've read anything about jointly held accounts between a parent and an adult child, you've probably absorbed the general rule: Ontario law presumes it's not a gift, unless there's evidence otherwise. So it's a fair question to ask whether the same skepticism applies when the child on the account is still a minor. The answer, generally, is no — a different, older presumption tends to survive specifically for minor children, and it points the opposite way.
This distinction matters for parents setting up accounts for young children, and for anyone administering an estate where a minor was named on a parent's account.
Two Competing Presumptions in Canadian Trust Law
When someone transfers property to another person without receiving anything in return, the law has historically applied one of two competing default assumptions, depending on the relationship between the parties:
- Presumption of resulting trust — the default assumption that no gift was intended; the recipient is presumed to hold the property in trust for whoever transferred it.
- Presumption of advancement — the opposite default assumption, that a gift was intended, traditionally applied in certain family relationships where the law assumed the transferor had a reason to want to benefit the recipient outright.
Modern Canadian law narrowed where the presumption of advancement still applies. For transfers between a parent and an adult child, the presumption of resulting trust generally applies today — the law no longer automatically assumes a parent meant to gift an adult child a share of an account.
Why Minor Children Are Treated Differently
The presumption of advancement is generally understood to survive specifically for transfers from a parent to a minor child, resting on the reasoning that a parent has an ongoing legal obligation to support their minor child — so the law is more willing to assume a transfer for the child's benefit reflects a genuine gift, rather than a bookkeeping convenience. This is a narrower, relationship-specific exception, not a general rule that any transfer to a young person is presumed to be a gift.
What This Looks Like in Practice
| Adult Child Added to Account | Minor Child Added to Account | |
|---|---|---|
| Default legal presumption | Resulting trust (not a gift) | Advancement (a gift), generally |
| Rests on | Reversed by modern case law | Parent's legal obligation to support a minor |
| Who has to prove otherwise | The child, to show a gift was intended | Generally, whoever argues it was not a gift |
| Practical relevance | Common when a parent adds an adult child for banking convenience | Less common in practice — minors typically don't operate accounts independently |
Why This Rarely Comes Up the Same Way as the Adult-Child Situation
In practice, disputes over the adult-child resulting trust presumption are common, because parents frequently add an adult child to an account for convenience while the parent is alive and still managing their own money. Minor children are less often named as joint owners on a parent's primary bank account in the first place — more commonly, money set aside for a minor child sits in a separate account the parent controls in trust for the child, or in a registered education savings plan, rather than as a true joint account with survivorship. Where a minor genuinely is named as a joint owner, though, the presumption of advancement is the relevant starting point, not the resulting trust presumption used for adult children.
What Still Needs Evidence
Even where the presumption of advancement applies, it remains a presumption — a starting point, not an unshakeable rule. It can still be challenged with evidence that a parent didn't actually intend a gift, just as the resulting trust presumption for adult children can be rebutted with evidence pointing the other way. The direction each presumption points simply changes which side has to come forward with that evidence first.
A Few Practical Notes for Parents
- [ ] If you're setting money aside for a minor child, understand whether the arrangement is a true joint account, a trust account you control, or a registered plan — each works differently
- [ ] Put your intention in writing regardless of which presumption technically applies — it avoids the argument altogether
- [ ] Understand that the presumption of advancement for a minor child is not the same as a rule that money "automatically" becomes the child's to access before adulthood
- [ ] Get advice before assuming either presumption will resolve a dispute in your favour — both remain rebuttable
Frequently asked questions
Does this mean money in a minor child's joint account is automatically theirs to control?
Not necessarily, and not immediately. A minor generally can't independently operate an account the way an adult can, so in practice a parent or guardian typically continues managing the funds regardless of whose name is on it, at least until the child reaches the age of majority.
What happens to the presumption once the minor turns 18?
The presumption of advancement is generally assessed based on the relationship and intent at the time the account was set up, not re-evaluated automatically once the child becomes an adult. If you're unsure how an existing arrangement would be characterized, get specific advice.
Is a trust account for a minor child the same thing as a joint account?
No. A trust account a parent controls "in trust for" a minor child is a different legal arrangement than a true joint account with the child as a named co-owner. The two are often confused, but they carry different consequences for who legally owns the funds and how they can be dealt with on the parent's death.
Can the presumption of advancement for a minor child still be challenged by other beneficiaries after a parent dies?
Yes. Like the resulting trust presumption for adult children, the presumption of advancement is rebuttable — other beneficiaries can still bring evidence suggesting no gift was genuinely intended, even where the presumption initially favours the child.
