Key takeaways
  • Property that passes by true right of survivorship goes to the surviving owner and not through the estate, whatever the will says.
  • Land granted to two or more people is presumed to be held as tenants in common unless the deed shows joint tenants, and an adult child added for free is presumed to hold in trust for the estate.
  • Check the parcel register and the bank documents early, and watch the six-month deadlines.

A parent's will says everything is to be divided equally among the children. Then you learn that one child, or a new partner, was named as a joint owner of the house or a bank account. It is natural to ask whether the will still controls.

The short answer is that a true right of survivorship usually beats the will. But there are several situations where a jointly held asset ends up back in the estate, or is counted for other claims. This article walks through them in plain terms.

The general rule: survivorship passes outside the will

Property passes to an estate trustee only if no one else has a right to take it by survivorship. When a joint tenant dies, their interest goes to the surviving joint tenant or tenants, not to the beneficiaries named in the will. This is true whether or not there is a will.

In practice, that means a house held in true joint tenancy can pass to the surviving owner without a Certificate of Appointment of Estate Trustee. Jointly owned property that passes automatically to the other owner is also left out of the value of the estate for estate administration tax.

When the will still matters in practice

Many families assume that two names on a deed or account means survivorship. That is not always so. The situations below are the main ones where the estate may still have a say.

SituationWhat can happen
Deed does not say joint tenantsCo-owners are presumed to be tenants in common, so there is no survivorship between them
Adult child added for freeChild is presumed to hold in trust for the parent, and on death for the estate
Matrimonial home shared with a non-spouseJoint tenancy is deemed severed just before death
Owners die at the same timeUnless a contrary intention appears, joint owners are treated as tenants in common
Dependant support claimJoint assets can be counted in the net estate

Tenants in common and the wording of the deed

Land granted to two or more people is 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.

The same presumption applies where one co-owner is the other's spouse, and for this rule spouse includes two people living together in a conjugal relationship outside marriage. Spouses and common-law partners therefore hold as joint tenants only if the deed says so. Executors and trustees are an exception to the general presumption, and people who acquire land by length of possession hold as tenants in common.

Added to title or an account for free: resulting trust

For gratuitous transfers, the presumption of resulting trust is the general rule, and the person receiving the transfer must show a gift was intended. An adult child added to a parent's account or property without paying is presumed to hold it in trust for the parent, and on death for the estate. The presumption of advancement, which treats the transfer as a gift, is confined to minor children, although an adult child's financial dependency can be strong evidence against the trust.

Courts may look at the following when deciding what the parent intended:

If the survivor does hold a joint asset in trust for the estate, it does not escape estate administration tax. Heirs may also challenge the survivor, who may need to show the deceased meant the funds as a gift.

Other ways joint property is pulled back in

Income tax also applies separately. A deceased person is considered to have sold their capital property just before death, even if it passes by survivorship. A rollover is available for a surviving spouse or common-law partner who is resident in Canada, if the property is locked in for them within 36 months of death.

What to do next

Whether a joint asset is really the survivor's or the estate's depends on the facts. A lawyer can review the documents with you before anyone acts.

Frequently asked questions

Can a will leave my share of a jointly owned house to someone else?

Generally not if the house is held in true joint tenancy, because your share goes to the surviving joint tenant and the will does not reach it. One exception is a matrimonial home held jointly with someone other than your spouse, such as a child: the joint tenancy is deemed severed just before death and your share goes into the estate. If the owners are tenants in common, each share does not pass by survivorship.

Is a bank account in joint names always the survivor's?

No. Many joint accounts carry survivorship, but an adult child added without paying is presumed to hold the funds in trust for the parent's estate. The survivor may need to show a gift was intended.

How do I find out how a parent held title?

Ontario land records, including the parcel register, are searched through OnLand, where anyone can self-search for a fee. How those records answer the joint tenancy question for a particular property is worth confirming with a lawyer, who can help you read them.

Do I need probate for a house that passes to a surviving joint owner?

Often not. A house held in true joint tenancy by a surviving owner can be dealt with without a Certificate of Appointment of Estate Trustee. The survivor deals with it through a land registry survivorship application.
