Introduction

Separation is emotional. It’s also financial—and often confusing. One of the first questions many couples ask is what happens to the mortgage after separation in Ontario. The family home is usually the largest shared asset, and the mortgage tied to it doesn’t disappear just because the relationship ends. Whether you’re married or in a common law relationship, understanding how mortgages, equity, and legal obligations are handled can help you make smarter decisions and avoid costly mistakes during an already difficult time.

Common law spouses should be aware that their legal rights and property division differ from those of married couples, especially regarding property ownership, support, and legal claims.

It’s important to note that both spouses are generally still responsible for shared debts, such as the mortgage, even if they no longer live in the home.

1. The Mortgage Doesn’t Automatically Change After Separation

After separation, the existing mortgage stays exactly the same until action is taken.

The lender doesn’t care who moved out or who caused the separation.

If both names are on the mortgage, both spouses are still responsible for the mortgage payments. It is important to communicate with your mortgage lender about any changes in your relationship or living situation to avoid misunderstandings, penalties, or potential foreclosure.

This applies even if only one spouse is living in the house.

Continued co-ownership typically requires a clear, written agreement and can complicate future borrowing.

2. The Matrimonial Home Under Ontario Law

Under Ontario law, the matrimonial home—also called the family home—is treated differently than other assets. The matrimonial home is defined as the property that spouses ordinarily occupied together at the time of separation.

Both spouses have an equal right to possession, regardless of who paid the down payment or whose name is on title. Both spouses have equal rights to possess the matrimonial home, regardless of whose name is on the title.

This rule comes from the Family Law Act, which aims to protect fairness during separation and divorce. Under the Family Law Act, a matrimonial home has specific protections; one spouse cannot sell or mortgage it without the other’s consent.

The full value of the matrimonial home is included in property division, and it is treated differently from other property such as furniture, household items, or property brought into the relationship.

3. Married vs Common Law Couples

This is where things change quickly.

For common law spouses in Ontario, the legal rights and property division after separation are different from those of married couples. Married couples follow strict rules under the Family Law Act, which provide for automatic equal division of property. In contrast, common law spouses do not have automatic rights to property division; instead, property is divided based on ownership and individual contributions, unless there’s a cohabitation agreement.

In a common law relationship, ownership matters more than marital status.

4. Who Pays the Mortgage During Separation?

Mortgage payments are considered part of ongoing financial obligations.

Sometimes both spouses continue to pay the mortgage.

Other times, the spouse living in the home pays alone or one spouse may pay out the other’s share of the home equity.

But here’s the key point: missed payments affect both parties if both names are on the mortgage.

If the sale of the home does not cover the mortgage, both parties are responsible for paying the remaining balance.

5. Separation Agreements and the Mortgage

A separation agreement is critical.

A properly signed separation agreement outlines who pays the mortgage, who lives in the home, and what happens next.

Without it, disagreements can escalate fast and end up in court.

6. Selling the House After Separation

For many couples, the cleanest solution is to sell the house. If the spouses cannot agree on what to do with the matrimonial home, selling it may be the best option.

The home is sold at fair market value.

The mortgage is paid off.

Real estate commission, legal fees, and costs are deducted.

What remains is equity, which is divided—often through an equalization payment.

When spouses agree on selling or dividing the home, the process is usually smoother and less contentious.

7. What Is Equalization?

Equalization is about balancing net family property.

In Ontario, property acquired during a marriage must be split equally when a marriage ends.

Each spouse calculates assets and debts from the date of marriage to separation. The process to divide property includes special rules for the matrimonial home, which is treated differently from other assets.

The equalization payment is calculated by comparing the value of each spouse’s share of the family property.

The spouse with the higher net value pays the difference so both end up with an equal spouse’s share.

The matrimonial home plays a major role in this calculation.

8. One Spouse Keeping the Home

Sometimes one spouse wants to stay. If one spouse wants to remain in the matrimonial home, they may need to buy out the other spouse’s share.

This is known as a spousal buyout. In some cases, a spouse assumes the existing mortgage, meaning one spouse takes over the mortgage payments and responsibility for the home, provided the lender allows it and the spouse qualifies on their own.

The spouse keeping the property must buy out the spouse’s share of the equity. It is important to clarify how the spouse owns the property, as ownership rights are divided or recognized separately from possession or exclusive use.

That requires knowing the exact buyout amount—not a guess.

A spousal buyout allows one spouse to keep the matrimonial home by paying the other spouse for their share.

9. Calculating the Buyout Amount

The buyout starts with the property value.

Subtract the mortgage balance.

The remaining amount is home equity.

That equity is split equally unless otherwise agreed, and one spouse may need to pay the other spouse their share of the equity.

This calculation often requires a real estate lawyer or family lawyer to confirm accuracy.

If one spouse wants to keep the matrimonial home, they typically need to buy out the other spouse’s share, which involves refinancing the mortgage.

10. Refinancing the Mortgage

If one spouse keeps the home, refinancing is usually required.

The lender needs to remove the other spouse from the mortgage.

That means qualifying on a single income, not combined income.

This is often the biggest hurdle.

11. Dealing With Mortgage Penalties

Refinancing or selling early can trigger mortgage penalties.

These can be significant—especially with variable rate mortgages or fixed terms.

A mortgage broker can help compare options and minimize penalties where possible.

12. Child Support, Spousal Support, and the Mortgage

Support payments matter.

Child support and spousal support affect affordability and lender approval.

Some lenders allow support income to help qualify.

Others treat it cautiously.

This is where professional advice becomes essential.

13. What If One Spouse Stops Paying?

If one spouse stops contributing, the lender still expects payment.

Missed payments damage credit for both parties.

This can impact future borrowing, refinancing, or securing a new mortgage.

Court intervention may be required to force compliance.

14. Special Rules for Common Law Couples

Common law couples don’t benefit from automatic equalization. Common law spouses should know that property division is not automatic and depends on who owns the property and each person’s contributions.

Ownership on title matters.

So does proof of contribution.

Disputes can become complicated fast, especially without a written agreement.

15. Cohabitation Agreements and the Mortgage

For common law couples in Ontario, a cohabitation agreement is more than just paperwork—it’s your best protection when separating. Unlike married couples, common law couples aren’t automatically covered by the Family Law Act when it comes to dividing the family home or handling the mortgage. That’s why a clear, signed cohabitation agreement is essential.

A well-drafted cohabitation agreement should spell out exactly how mortgage payments will be handled if you separate, who will assume responsibility for the mortgage, and how any equity in the property will be divided. It can also outline what happens to the family home—whether one person keeps it, you sell, or another arrangement is made.

Working with a mortgage broker or real estate lawyer can help you understand your options and ensure your agreement covers all the financial and legal details. This proactive step can prevent disputes, protect your rights, and make the separation process much smoother for both parties. In short, if you’re in a common law relationship and own property together, don’t wait—get a cohabitation agreement in place before issues arise.

16. Legal Advice: Why It’s Essential During Separation

Separation isn’t just about emotions—it’s about making big decisions that affect your financial future. That’s why getting legal advice from a family lawyer or real estate lawyer is so important. A lawyer can help you understand your rights and obligations under the Family Law Act, especially when it comes to dividing net family property, handling the matrimonial home, and meeting ongoing financial obligations.

Legal advice is crucial for drafting a separation agreement or cohabitation agreement that clearly sets out who is responsible for the existing mortgage, how property will be divided, and what happens if one spouse wants to assume or refinance the mortgage—or if a new mortgage is needed. Lawyers can also guide you through removing a spouse from the title, ensuring all agreements are legally binding, and protecting your interests if things get complicated.

Don’t try to navigate these decisions alone. The right legal advice can help you avoid costly mistakes, ensure your agreements are enforceable, and give you peace of mind as you move forward after divorce or separation.

17. Real Estate Considerations Beyond the Mortgage

The family home is often the biggest asset in a separation, but there’s more to consider than just the mortgage balance. If one spouse is keeping the house, they may need to refinance the existing mortgage or qualify for a new mortgage—often on a single income. This can trigger mortgage penalties, require mortgage default insurance, or involve switching from a variable rate mortgage to a fixed rate, depending on your lender’s requirements.

Beyond the mortgage, there are other real estate costs to factor in: real estate commissions if you sell, appraisal fees to determine property value, and legal fees for transferring ownership. If you’re transferring property between spouses, understanding the principal residence exemption is key to avoiding unexpected tax bills. And don’t forget about other assets—like investments or pensions—that may need to be divided alongside the family home.

A mortgage broker or real estate lawyer can help you navigate these complexities, compare your options, and plan for all the costs involved. By looking at the full picture—not just the mortgage—you’ll be better prepared to make decisions that protect your financial stability and set you up for a fresh start.

Practical Tips for Navigating the Mortgage After Separation

• Speak with a family lawyer early
• Get the home professionally valued
• Don’t rely on verbal agreements
• Understand your lender’s rules
• Protect your credit at all costs
• Consider long-term affordability
• Factor in penalties and fees
• Get legal advice before signing anything

Small steps now prevent big mistakes later.

The Emotional Side of the Family Home

The house isn’t just an asset.

It’s memories, routines, and security.

That emotional attachment can cloud judgment.

Making decisions based on facts—not fear—leads to better outcomes.

When Court Orders Are Involved

Sometimes couples can’t agree.

A court order may force a sale or refinance.

Courts aim for fairness, not comfort.

That’s why negotiated agreements are usually better.

The Principal Residence Exemption

Selling the matrimonial home may qualify for the principal residence exemption.

This can protect you from capital gains tax.

But only if rules are followed properly.

Other Assets and Joint Debts

The mortgage isn’t the only concern.

Unlike the matrimonial home, other property such as furniture, household items, and assets brought into the relationship are treated separately during property division.

Other joint debts, savings, pensions, and investments must be considered.

Everything ties together in equalization.

Planning Your Path Forward

Every situation is unique.

Some sell. Some refinance. Some delay decisions.

The best path depends on income, children, legal status, and long-term goals.

With the right support and information, you can make confident decisions about your mortgage and property, moving forward after separation.

Fresh Start, Financially and Emotionally

Separation is hard.

But clarity brings relief.

Understanding the financial side of separation helps you move forward with confidence.
