Key takeaways
  • When a parent adds an adult child to an asset without payment, the child is presumed to hold it in trust for the parent and, on death, for the estate.
  • Survivorship property goes to the surviving owner and not into the estate, even if the will says otherwise.
  • Courts look at evidence of what the parent intended at the time of the transfer, so documents and records matter.

A parent adds one child to the title of the family home, and years later the parent dies. The other children learn that the house, or a bank account, went to that one child and not into the estate. Tempers rise quickly.

The legal question is usually not what the will says. It is whether the parent meant to give the child a real ownership interest, or only wanted help managing things. This article explains how Ontario courts approach that question and what usually matters.

Why the will may not control the house

Property passes into the estate only if no one else has a right to take it by survivorship. Property that passes by survivorship goes straight to the surviving owner, whether or not there is a will. A deceased joint tenant's interest goes to the surviving joint tenant, not to the will's beneficiaries.

A parent can add a child to title by conveying the property to themselves jointly with that child. If the joint tenancy is real and stands, the house may never become part of the estate. That is why siblings often turn to a trust argument instead.

Being named on title does not always mean joint tenancy. Land conveyed to two or more people is generally held as tenants in common unless the document shows on its face that they take as joint tenants. A tenant in common's share does not pass by survivorship.

Gift or trust: the presumption courts start from

For transfers made without payment, the starting rule is a presumption of resulting trust. The person who received the transfer must show that a gift was intended. An adult child added to a parent's account or asset without paying for it is presumed to hold it in trust for the parent and, on death, for the estate.

There is an exception for minor children, where the presumption of advancement (a gift) applies. Financial dependency of an adult child does not trigger that presumption, although it can be strong evidence against the trust.

If the court finds a resulting trust, the child holds the property for the estate. In that case the value counts for estate administration tax, because property held in another person's name that belongs to the deceased is included.

What evidence tends to matter

The question is what the parent intended when the transfer was made. Courts may consider the following kinds of evidence:

For joint accounts, survivorship rights vest when the account is opened, so the gift is made during life. What is gifted is the survivor's interest in the balance at death.

Special situations that change the answer

SituationEffect
Matrimonial home held jointly with a child, not the spouseThe joint tenancy is deemed severed immediately before death, and the share goes into the estate.
Spouses holding jointlyJoint title is proof, without evidence to the contrary, that they intended to own as joint tenants.
Dependant makes a support claimProperty held as joint tenants at death can be counted in the net estate for that claim.

Adding a child can also have tax effects. A gift of capital property is treated as a sale at fair market value when you give it, and the automatic rollover applies to a spouse or common-law partner, not to children, except for qualifying farm or fishing property. A deceased person is also treated as having sold capital property just before death, even if it passes by survivorship.

What to do next

Any joint owner or tenant in common may be compelled to partition or sell land under the Partition Act. Outcomes depend heavily on the evidence, so get advice early.

Frequently asked questions

Does the child on title automatically get the house?

Not necessarily. If it is a true joint tenancy, the property passes to the surviving owner and not through the will. But an adult child who paid nothing is presumed to hold it in trust for the parent's estate unless they can show a gift was intended.

Does it matter that the child was financially dependent on the parent?

Dependency alone does not create a presumption of gift for an adult child. It can, however, be strong evidence that rebuts the trust.

Can I check how my parent held title?

Yes. Land registry records, including the parcel register, are searched through OnLand, and ServiceOntario cannot search or explain records for you.

Does adding a child to title have tax consequences?

It can. A gift of capital property is treated as a sale at fair market value when given, and the automatic rollover does not apply to children except for qualifying farm or fishing property. An accountant can confirm your situation.
