Key takeaways
  • A will cannot by itself sever a joint tenancy, so survivorship takes precedence over what the will says.
  • When one joint tenant dies, the property automatically passes to the surviving owner.
  • A joint tenancy can be severed during life, but a secret intention that was never shared with the other owner is not enough.
  • Property that passes by survivorship is generally left out of the value used to calculate Estate Administration Tax.

A parent dies. Their will leaves the family house to one child, but the title to the house shows the parent and another child as joint owners. Now the family is asking which document wins: the will or the way the property was registered.

In Ontario, the answer usually turns on how the property was owned, not on what the will says. This article explains the general rule, the ways a joint tenancy can end before death, and what typically happens at the land registry afterwards. It is general information, not advice on your particular house.

The short answer: survivorship usually wins

If you own property as a joint tenant in Ontario, it automatically passes to the surviving owner when you die. That is called the right of survivorship. The Court of Appeal for Ontario has said that a will cannot by itself sever a joint tenancy, and that survivorship takes precedence over a will.

The reason is that the property never becomes part of what the will controls. The right of survivorship applies only to interests held in a joint tenancy, and property that does not pass by survivorship goes to the deceased's personal representative instead. The Province also lists jointly owned property as an example of an asset that is distributed depending on how it is owned.

So in the situation above, if the house really was held in a joint tenancy at the moment of death and nothing had ended that tenancy, the surviving joint owner would generally take the house, whatever the will says.

Joint tenants and tenants in common are different

Many families use the word "joint" loosely. The legal form of ownership matters a great deal. The Court of Appeal has described survivorship as the critical distinction between a joint tenancy and a tenancy in common.

Type of ownershipWhat happens when one owner dies
Joint tenancyThe interest passes to the surviving co-owners
Tenancy in commonThe interest passes to the deceased's estate, so the will (or intestacy rules) applies

The first thing to find out, then, is how title is actually registered. A recent copy of the title or the registered transfer will usually show it. Do not rely on memory or family assumptions.

Can a joint tenancy be ended before death?

Yes. Ending a joint tenancy is called severance. Ontario's Court of Appeal recognizes three ways: one owner acting unilaterally on their own share, such as selling or encumbering it; a mutual agreement between the co-owners; or a course of dealing showing that all the owners mutually treated their interests as severed.

There are limits to each of these:

For land, Ontario's registration guidance says a joint tenant can sever by executing and registering a deed or transfer to themselves, after which the registrar shows that person as a tenant in common with the other registered owners. Ontario says no land transfer tax is payable on that kind of transfer to oneself, as long as the affidavit says the deed is registered solely to give effect to the severance.

Mortgages and other complications

Registering a charge (mortgage) by fewer than all of the joint tenants does not automatically sever the joint tenancy. Whether the owner intended to sever is a question of fact for the courts, although severance does occur if the chargee enforces by power of sale or foreclosure.

If a joint tenant who charged their interest alone dies first, the survivors are entered on title subject to the charge on a survivorship application, and the charge is not removed unless a cessation is registered or a court orders its discharge.

Spouses are a special case. Under s. 26(1) of the Family Law Act, if a spouse dies owning a family residence as a joint tenant with a third party who is not their spouse, the joint tenancy is deemed severed immediately before death, according to the land registry bulletin. In that situation the deceased's share may not pass by survivorship at all. Because details like this are easy to get wrong, have a lawyer review the facts.

What happens at the land registry after death

The surviving joint owner normally deals with title through a survivorship application. In Land Titles, the application under s. 123 of the Land Titles Act uses a statement that the applicant held the property as joint tenant with the deceased, that the applicant is entitled as surviving joint tenant, and the date of death.

For deaths on or after March 1, 1986, the application must also include a Family Law Act statement: that the deceased and the survivor were spouses, that the deceased was not a spouse at death, or that the property was not a matrimonial home. A solicitor must sign these statements. Form details have changed recently, so confirm the current requirements before relying on any older guide.

Probate is not always required. Ontario says it is normally required where the deceased owned real property, but real property that does not pass by right of survivorship is a reason to apply. Estate Administration Tax also leaves out assets held in joint ownership that automatically become the other owner's.

What to do next

If the family disagrees, avoid acting on your own view of what the deceased wanted. Whether a joint tenancy was severed can turn on a unilateral act, an agreement or how the owners dealt with each other, so keep your records and let a lawyer assess your position.

Frequently asked questions

If my parent's will leaves the house to me, but the title is joint, who gets it?

Generally the surviving joint owner, because survivorship takes precedence over a will. The exception is if the joint tenancy was properly severed before death, which depends on the facts.

Can my parent sever a joint tenancy secretly?

Not safely. A secret intention, or one declared behind the other co-owners' backs, is not enough on the course-of-dealing method. Registering a transfer to themselves is a recognized way to sever.

Do I need probate for a house held in joint tenancy?

Not necessarily. Ontario says real property that does not pass by right of survivorship is a reason to apply for probate, and survivorship property is generally left out of the Estate Administration Tax calculation. The survivor typically uses a survivorship application.

Does a mortgage by one joint owner end the joint tenancy?

Not automatically. Registering a charge by fewer than all joint tenants does not automatically sever the tenancy, and intent is a question of fact for the courts. A lawyer can look at the specific registration.
