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

To buy out your spouse in Ontario, you must legally agree on the home’s value, draft a formal Separation Agreement, and qualify for a Spousal Buyout Mortgage. This program allows you to finance up to 95% of the home’s value to pay the equalization amount owed to your ex-partner.

When a marriage ends, keeping the family home is often a top priority to provide stability for the children. However, in expensive Ontario real estate markets like Toronto, Kitchener, and Ottawa, paying your spouse for their half of the house is a massive financial hurdle. You cannot simply cross their name off the deed; you must execute a formal, legally binding buyout.

Successfully buying out an ex-partner requires a coordinated team: a family lawyer, a real estate appraiser, and a specialized mortgage broker. A single mistake in your paperwork can cause a bank to reject your financing. We recommend using our directory to find a local Ontario family law firm to draft the necessary agreements and protect your housing stability. 🔍

Step-by-Step Process for a Spousal Buyout in Ontario

A buyout is effectively a complex real estate transaction between two separating spouses. The process heavily relies on strict banking regulations and the formal execution of Ontario family law documents.

Step 1: Agree on the Fair Market Value

You cannot use the property tax assessment or a random guess from a realtor. You must hire an independent, certified residential appraiser to determine the exact fair market value of the home on the current date. If you and your spouse disagree on the value, you may each need to hire your own appraiser and average the two numbers. 📈

Step 2: Draft the Separation Agreement

Canadian mortgage lenders will not approve a spousal buyout without a finalized, legally binding Separation Agreement. This document must clearly outline the division of your Net Family Property, child support, spousal support, and the exact buyout amount. Both spouses must receive Independent Legal Advice (ILA) before signing to ensure the contract holds up in court.

Step 3: Secure the Spousal Buyout Mortgage

Normally, refinancing a home in Canada caps out at 80% of the home’s value. However, the CMHC-backed Spousal Buyout Program allows you to borrow up to 95% of the home’s value specifically to pay off your ex-spouse and consolidate joint debts. You must individually qualify for this new mortgage based solely on your own income and any support payments you receive. 💳

Step 4: Execute the Spousal Transfer of Title

Once the financing is approved, your real estate lawyer will handle the closing. They will use the mortgage funds to pay out your ex-spouse’s equalization amount. Simultaneously, they will register a transfer of title with the Ontario land registry, removing your spouse’s name and making you the sole legal owner of the property.

How Much Does it Cost in Ontario?

A buyout involves both family law fees and real estate transaction costs. Fortunately, a transfer between spouses resulting from a separation is generally exempt from the massive Ontario Land Transfer Tax. 💸

Service / ExpenseEstimated Cost (CAD)
Independent Real Estate Appraisal$350 to $600
Drafting Separation Agreement$1,500 to $3,500+
Real Estate Lawyer (Closing & Title Transfer)$1,000 to $2,000
Ontario Land Transfer Tax$0 (Usually Exempt via spousal transfer)

How Long Does the Process Take?

If both spouses are amicable and agree on the home’s value, drafting the separation agreement and securing mortgage approval usually takes 2 to 3 months. However, if your spouse refuses to sell or contests the appraisal value, resolving the dispute through family court or mediation can delay the buyout for 6 to 12 months.

Frequently Asked Questions (FAQ)

What if I cannot qualify for a mortgage on my own?

If your single income cannot support the new mortgage, you cannot buy out your spouse. The most common alternative is selling the house on the open market, paying off the existing mortgage, and dividing the remaining cash equity between the two of you.

Does my ex still have to pay the old mortgage?

No. When you complete the buyout, the new mortgage is entirely in your name. Part of the transaction involves legally discharging the old joint mortgage so your ex-partner is completely released from all financial liability to the bank.

Can my spouse refuse the buyout?

Yes, your spouse does not have to accept your offer. If they want the house sold on the open market to maximize the profit, they can force the issue. Your lawyer may need to file a motion for a Partition and Sale or negotiate heavily to reach an agreement.

Do we deduct real estate fees from the buyout price?

This is highly negotiable. Often, the buying spouse will argue that a “notional” real estate commission (usually 4% to 5%) should be deducted from the home’s value before splitting it, since they will eventually have to pay those fees when they sell in the future. The selling spouse often fights this deduction.
