Buying Out Your Spouse's Share of the House in Ontario

How a house buyout works in an Ontario separation: what the home is worth, how the equalization payment fits in, and where refinancing comes into it.

Key takeaways
  • A buyout is usually built into the property settlement, because the home is valued as of the separation date and the mortgage is deducted at that date.
  • The spouse with the larger net family property pays half the difference as an equalization payment.
  • Whether a lender will lend to you alone is a matter between you and the lender, so ask early and confirm with a lawyer or mortgage professional.
  • Agreements reached at a case conference are written as Minutes of Settlement.

If you want to stay in the family home after separation, the usual route is a buyout: you keep the house, and your spouse receives their share in money or in other assets. It sounds simple, but it connects three separate issues: what the house is worth, how the overall property division works out, and whether you can afford the financing.

This article explains how those pieces fit together in Ontario, using the basic rules for married spouses. Your numbers and your lender's requirements will be specific to you, so treat this as a map and not a plan.

How the house fits into property division

Net family property is the value of property at the separation date, minus debts and excluded property, less the same net value at the date of marriage. A negative result counts as zero, and the spouse with the larger share pays half the difference as an equalization payment.

The family home is treated generously towards sharing. Its full value is shared even if one spouse owned it before marriage or received it as a gift or inheritance, unless the spouses agree otherwise. Only the house and a small surrounding area count. The mortgage is deducted at separation, but not in the marriage-date calculation.

In practice, this means a buyout is rarely a standalone deal. It is one part of the whole property calculation, which also includes pensions, savings, vehicles and debts. An Ontario pension counts as property in the division, and the pension administrator can provide information about its value.

Valuing the home

The key date is separation, because that is the date used for valuing property and debts. If the home's value is disputed, spouses often obtain a professional appraisal, sometimes jointly, so that both accept the same number. Whether you need one, and what type, depends on your circumstances.

If you disagree about value, a lawyer can explain how to put the issue in front of a judge or settle it by agreement. Both spouses also provide financial information, using Form 13.1 where property or debt claims are made. These statements must be sworn or affirmed before a lawyer or commissioner of oaths, and a courthouse clerk can commission them for people without a lawyer.

Paying your spouse: equalization, cash or other assets

The buyout amount is usually worked out by combining the home equity with the rest of the property calculation. If you keep the house, its value is on your side of the ledger. If your net family property ends up larger, you owe an equalization payment of half the difference. If your spouse's is larger, they owe you, and that amount can reduce what you must pay to keep the home.

Way of payingHow it generally worksPoints to check
Cash from refinancingYou borrow against the home and pay your spouseWhether a lender will approve you alone
Offset against other assetsYour spouse keeps savings or other property of similar valueFair valuation of each asset
Retirement savings transferA transfer to a spouse's RRSP or RRIF on marriage breakdown is allowed if the spouses live separate and apart and it is made under a court order or written separation agreement settling property rights, and it is not included in income solely because of the transferTax advice before agreeing
Payments over timeThe agreement sets out instalmentsHow the payments are secured

Refinancing and the lender

Most buyouts that use borrowed money depend on a lender who must decide whether to lend to you alone. Lenders generally look at your income, credit history, existing debts and the value of the home. Their criteria differ, and the information in this article does not tell you what any particular lender will accept.

Because lender approval can take time and may fail, it is sensible to speak with a mortgage professional before you commit to a buyout number in a settlement. Ask whether you qualify on your own income, including any support you receive. In deciding spousal support, the court considers each spouse's condition, means, needs and other circumstances, and any order, agreement or arrangement relating to support. Whether support will be counted by your lender is something to ask the lender.

Build the timing into your agreement. Many people include a closing date and a plan for what happens if the financing is not approved.

What to do next

If you reach agreement, it should be in writing. When it is reached in court, agreements are written as Minutes of Settlement. If you need the court to decide property issues, a general Form 8 application is used where claims beyond divorce are made.

Frequently asked questions

Do I have to buy out my spouse if I want to keep the house?

How you keep the home depends on your situation, so it is worth confirming with a lawyer. The equalization calculation determines the money owed, but how that is paid, and whether the home is sold, depends on the facts and your finances.

Is the house value shared if I owned it before we married?

If the house is your family home, its full value is shared even if one spouse owned it before marriage or received it as a gift or inheritance, unless the spouses agree otherwise. Whether a particular property counts as the family home depends on the facts, so it is worth confirming with a lawyer.

What date is the house valued at?

Net family property is based on the value of property at the separation date. The mortgage is deducted at separation as well.

Can I use my spouse's RRSP to settle the buyout?

Sometimes retirement savings are moved between spouses, but there are rules. A transfer on marriage breakdown is allowed if the spouses are living separate and apart and it is made under a court order or a written separation agreement settling property rights. Get tax and legal advice before relying on this.
