With nearly 30 years navigating Ontario real estate law, close to 30,000 transactions closed without a title claim, and recognition in multiple publications, our goal is simple: deliver clear, practical insights you can use.
Today we’re starting a new short series:
Family Law & Real Estate — where ownership, title, and relationships collide.
And we begin with one of the most misunderstood rules in Ontario property law.
The Matrimonial Home Rule — Why Being Off Title Doesn’t Mean You Have No Rights
Many people assume that if their name isn’t on title to a home, they have no legal interest in it.
In Ontario, that assumption can be very wrong.
Here are three things every homeowner, buyer, and real estate professional should know.
1. A married spouse can have powerful rights in a home even if they are NOT on title
Under Ontario’s Family Law Act, a property that is ordinarily occupied by spouses as their family residence is legally considered a “matrimonial home.”
This creates rights that override normal property law principles.
For example:
• Both spouses have equal rights to possession of the home — even if only one spouse owns it.
• A titled spouse cannot sell, refinance, or mortgage the home without the other spouse’s consent.
• A court can even grant exclusive possession of the home to the non-titled spouse in certain circumstances.
In other words:
Title ownership and occupancy rights are not the same thing in family law.
This is why real estate lawyers always ask sellers a critical question:
“Is this property a matrimonial home?”
Because if it is — the spouse must consent to the transaction.
2. The matrimonial home is treated differently from all other property in divorce
The matrimonial home has a special legal status in Ontario.
Even if one spouse owned the home before the marriage, that spouse typically cannot deduct its value from their property equalization calculation.
This often surprises people.
Example:
• A spouse buys a house before marriage
• The couple lives there during the marriage
• The house becomes the matrimonial home
When the relationship ends, the owner cannot deduct the home’s pre-marriage value from their net family property.
In practical terms, this can significantly change the financial outcome of a separation.
3. Common-law partners do NOT have the same automatic rights
Here is where things change dramatically.
In Ontario, common-law spouses do not receive the same property rights as married spouses.
There is no automatic property division regime.
If a common-law partner wants to claim an interest in a home owned by the other partner, they usually must rely on equitable claims such as:
• unjust enrichment
• constructive trust
• resulting trust
These claims typically require proving:
• one partner was enriched
• the other suffered a deprivation
• there was no legal reason for the enrichment
The Supreme Court of Canada discussed these principles in Kerr v. Baranow, a leading case on property claims between unmarried partners.
Unlike married spouses, common-law partners usually must prove their entitlement in court.

Bottom line
Real estate ownership in Ontario does not exist in isolation.
Family law can create powerful rights that override title, affect sale transactions, and dramatically change financial outcomes during separation.
