Key takeaways
  • The full value of the family home must be shared even if one spouse owned it before the marriage, unless the spouses agree otherwise.
  • Both married spouses have an equal right to possess the matrimonial home, whoever holds title.
  • A court can give one spouse exclusive possession of the home even if it is in the other spouse's name.

You bought your home before the wedding, so it probably feels like yours alone. After separation, though, Ontario treats a family home differently from most other property.

Two separate questions come up: how the home's value counts in the property division, and who can live in it and what can be done with it while things are sorted out.

How the home's value is counted

When married spouses separate, the spouse whose net family property is smaller is entitled to one-half of the difference between the two net family properties. A court may award a spouse more or less than half the difference if equalizing them would be unconscionable, and one factor it considers is a spouse's intentional or reckless depletion of their net family property. Property you owned at separation is valued as of the day you separated, and property you owned on the wedding day is valued as of the date of marriage.

Ontario's guidance says debts at marriage are subtracted from property owned at marriage, except debts tied to the family home, such as a mortgage. The remaining mortgage on separation is a debt that reduces a spouse's net family property.

Why a pre-marriage home is treated differently

The family home carries a special sharing rule. Its full value must be shared even if one spouse owned it before the marriage or received it as a gift or inheritance, unless the spouses agree otherwise.

This differs from other property. Property acquired during the marriage by gift or inheritance from a third person, personal-injury damages, and property the spouses agreed in a domestic contract to exclude are not included in net family property, but that exclusion does not apply to a matrimonial home.

The matrimonial home rules

A matrimonial home is every property in which a spouse has an interest and that is, or was at the time of separation, ordinarily occupied by the spouses as their family residence. These rules apply whoever holds title.

Exclusive possession of the home

Regardless of who owns the home, a court may order that one spouse be given exclusive possession of it, or part of it, for a period the court directs. It may also order periodic payments, deal with the contents, and order payment of repairs and maintenance. A temporary or interim order can be made on a motion.

In deciding, the court must consider these matters:

On the children's interests, the court considers the possible disruptive effects of moving and the child's views and preferences if they can reasonably be ascertained. A person in danger should call 911 or local police immediately.

If you are not married

The matrimonial home possession rights apply to spouses as defined in the Family Law Act, meaning married people. Ontario's guidance tells people who are not married to contact a lawyer about their rights and options regarding the home. Your position will turn on factors such as who holds title, so get advice before making decisions.

What to do next

Frequently asked questions

Is a house I owned before marriage excluded from property division?

The usual exclusions from net family property, such as gifts or inheritances from a third person, do not apply to a matrimonial home. The full value of the family home must be shared even if one spouse owned it before the marriage, unless the spouses agree otherwise.

Can my spouse make me leave a home they own?

Without a court order, a non-owning married spouse cannot be put out of the matrimonial home simply because the other spouse owns it. A court may also order exclusive possession to one spouse regardless of who owns the home.

Can I sell the home while we are separated?

Not without your spouse's consent, a release in a separation agreement, or a court order, unless another property is validly designated and registered as the matrimonial home.

What if we were never married?

The matrimonial home rules apply to married spouses. If you are not married, contact a lawyer about your rights and options regarding the home.
