Key takeaways
  • Each joint borrower is equally responsible to the lender for the unpaid mortgage balance, and separation does not change that contract.
  • If a court gives one spouse exclusive possession of the matrimonial home, it may also order a spouse to pay for repairs and maintenance.
  • Transferring a house to a spouse in settlement can roll over without immediate capital gains tax, with exceptions.

After a separation, a joint mortgage does not simply go away, because separation does not change your contract with the lender. Whether you live in the home or have moved out, it is natural to ask who has to keep paying and what happens if payments are missed.

The answer depends on your mortgage, your agreement or court order, and your circumstances. This article explains the main rules and the questions to raise early.

Your duty to the lender does not change

Each person who signs a mortgage as a joint borrower is equally responsible for repaying the unpaid balance. Separation does not change that contract with the lender.

In practice, this means a missed payment can affect both borrowers, whatever you have agreed between yourselves. Your lender is not normally a party to your separation agreement or court order, so what it will allow, such as removing a name or approving a refinance, is a separate question to confirm directly with the lender.

Who pays between the two of you

Between spouses, who pays what is usually settled by agreement or by court order. A separation agreement, like other domestic contracts, is unenforceable unless it is in writing, signed by the parties and witnessed. A court may set aside a domestic contract if a party failed to disclose significant assets, debts or other liabilities that existed when it was made.

If a spouse is given exclusive possession of the matrimonial home, the court may also order a spouse to pay for repairs and maintenance. When deciding possession, the court considers factors that include the children's best interests, the availability of other suitable and affordable housing, and any violence by a spouse against the other spouse or the children. How mortgage payments themselves are shared in a particular case depends on the facts.

Common situations

SituationWhat to consider
Both stay on the mortgage, one lives in the homeBoth remain responsible to the lender
One spouse is given exclusive possessionCourt may order repairs and maintenance payments
The home is to be soldA court can order property sold or partitioned
One spouse keeps the houseEqualization may be owed; see below

If the home is in one name only, the other spouse still has a right of possession, which is personal and ends when they stop being spouses unless an agreement or order says otherwise.

Keeping the home or selling it

A person may apply to court to decide a question of ownership or possession of particular property between them and their spouse. The court may declare ownership, order partition or sale, and order compensation if the property was disposed of.

If one spouse owes an equalization payment, the court may order payment and security for it. To avoid hardship, it may allow instalments or delayed payment for up to ten years, and it may order property transferred, partitioned or sold. A property order must not require the sale of an operating business or farm unless there is no reasonable alternative.

Transferring capital property such as a house to a spouse, or to a former spouse in settlement of rights arising from the relationship, rolls over at the transferor's adjusted cost base, so no capital gain is triggered at transfer unless the transferor elects out. This applies only if both people are resident in Canada at the time. A tax professional can confirm how it applies to you.

What to do next

If you worry that property is being depleted, a court may make orders restraining the depletion of a spouse's property in an equalization or title application.

Frequently asked questions

Am I still responsible for the mortgage if I move out?

If you signed as a joint borrower, you are equally responsible for repaying the unpaid balance, and separation does not change your contract with the lender. Moving out does not remove your name from the mortgage.

Can the court make my spouse pay for the house?

Where a spouse is given exclusive possession of the matrimonial home, the court may order a spouse to pay for repairs and maintenance. How mortgage payments are shared depends on the facts and on any agreement.

Can I get my name off the mortgage?

That is up to the lender, because your agreement or court order does not usually bind it. Ask the lender what it requires, and ask a lawyer to build the timing into your agreement.

What if we cannot afford the house on one income?

A sale may be an option, and a court can order property sold or partitioned. If an equalization payment is owed, the court may allow instalments or delayed payment for up to ten years to avoid hardship.
