Last week we looked at the matrimonial home rule and why a spouse can have rights to a property even if they are not on title.
Today we continue our Family Law & Real Estate series with three real-world situations where family law can unexpectedly affect property ownership, sales, and financing.
Here are three intersections every homeowner should understand.
1. You usually cannot sell a matrimonial home without your spouse’s consent
Even if only one spouse is on title, the law restricts what that spouse can do with the property.
Under section 21 of the Family Law Act, a spouse cannot sell, mortgage, or otherwise dispose of a matrimonial home unless:
• the other spouse consents
• a court authorizes the transaction
• the spouse has released their rights in a separation agreement
This means that a real estate transaction can collapse at the last minute if the non-titled spouse refuses to sign.
For lawyers handling closings, confirming spousal status is therefore a critical title step.
2. A court can give one spouse exclusive possession of the home
In separation situations, courts can order that one spouse has exclusive possession of the matrimonial home — even if the other spouse owns it.
When deciding whether to grant exclusive possession, courts may consider:
• the best interests of the children
• the financial positions of the spouses
• available alternative housing
• any history of family violence
These orders are powerful because they can require one spouse to leave their own property while the other continues living there.
This is one of the most significant ways family law can affect real estate ownership and occupancy rights.
3. Separation agreements often trigger property transfers
When couples separate, real estate is frequently transferred between spouses as part of a separation agreement or court order.
These transfers can involve:
• one spouse buying out the other
• refinancing to remove a spouse from title
• transferring title pursuant to a separation agreement
The good news:
Transfers between spouses pursuant to a separation agreement are often exempt from Ontario land transfer tax, provided the statutory requirements are met.
But the transaction still requires careful handling to ensure:
• the agreement supports the transfer
• the correct exemption is claimed
• mortgage financing issues are addressed
These transactions sit directly at the intersection of family law, tax law, and real estate law.

Bottom line
When relationships change, real estate is often the largest asset involved.
But property ownership is not governed solely by title — family law can create rights that affect possession, sale, refinancing, and value.
Understanding these rules early can prevent costly surprises later.
As always, if a real estate transaction intersects with separation, title transfers, or spousal rights, we’re here to help navigate the process.
