Spousal Buyout and Separation Mortgages in Niagara
Keeping the house after a separation means paying out your former partner's equity on one income. Here is how lenders finance a buyout in Ontario, when the 80% refinance limit applies, and when some insurers allow more.

How a spousal buyout is financed
When a relationship ends and one person keeps the home, the mortgage has to do two jobs at once: pay off the existing joint mortgage and pay the departing partner their share of the equity. The buyout amount is not something a lender decides. It comes from your separation agreement, negotiated by your family lawyers, and it may include more than half the equity (for example, an equalization payment or joint debts to be cleared). The lender's job is to decide whether the property value and your income alone can carry the new, larger mortgage.
- Conventional refinance limit
- 80% LTV
- Insured buyout programs (some insurers)
- up to 95% LTV
- Qualifying rate on a 4.29% insured rate
- 6.29%
- Prime GDS / TDS limits
- 39% / 44%
There are three common routes, and the right one depends mostly on how much equity is left after the buyout.
Route 1: a conventional refinance up to 80%
If the existing mortgage plus the buyout amount is at or below 80% of the appraised value, any A lender can refinance it as an ordinary uninsured refinance. You qualify alone at the stress-test rate. This is the simplest route and the most common one for couples who have owned for many years.
Route 2: an insured spousal buyout program above 80%
Refinances are normally capped at 80% loan-to-value. Some default insurers and lenders, however, treat a buyout between separating spouses or common-law partners more like a purchase, allowing financing above 80% and in some cases up to 95% of the value. Conditions vary, but typically include a signed separation agreement (not a draft), proceeds used to pay out the existing mortgage and the former partner's share as set out in that agreement, the departing partner coming off title, and the property being your principal residence. The default insurance premium is added to the mortgage and Ontario's 8% sales tax on it is paid in cash at closing. Not every lender offers this, which is one reason separating borrowers come to a broker.
Route 3: a credit union or B lender
If one income cannot pass prime ratios, some Ontario credit unions and alternative lenders allow higher debt-service ratios or count income differently. Rates and fees are higher, so this is usually a one- or two-year bridge until income or support payments are established.
Worked example: a $90,000 buyout in St. Catharines
Worked example: when 80% is not enough
A St. Catharines home appraises at $560,000. The joint mortgage balance is $380,000, so equity is $180,000. The signed separation agreement sets the buyout at $90,000. The remaining owner earns $108,000 a year on salary and receives $1,100 a month in child support, with a $450 car payment.
| Item | Amount |
|---|---|
| Existing mortgage payout | $380,000 |
| Buyout to former partner | $90,000 |
| New mortgage needed | $470,000 |
| Loan-to-value ($470,000 ÷ $560,000) | 83.9% |
| Conventional refinance maximum (80% × $560,000) | $448,000 |
| Shortfall on a conventional refinance | $22,000 |
| Insured buyout: premium at 2.80% (80.01%–85% tier) | $13,160 |
| 8% Ontario sales tax on premium (cash at closing) | $1,052.80 |
| Total insured mortgage | $483,160 |
| Payment at 4.29%, 25 years | $2,618 |
| Qualifying payment at 6.29% | $3,175 |
Qualifying income is $9,000 salary + $1,100 support = $10,100 a month. Property tax at St. Catharines' approximate 1.26% is $588 a month and heating is budgeted at $125. GDS = ($3,175 + $588 + $125) ÷ $10,100 = 38.5%. TDS adds the $450 car payment: 43.0%. Both are under the 39% and 44% limits, so the file works through an insured buyout program, assuming the lender counts the support with the agreement and proof of receipt. On salary alone ($9,000 a month) GDS would be about 43%, and the file would move to Route 3.

Income on one paycheque: what lenders count
| Item | Typical treatment | What to provide |
|---|---|---|
| Your employment income | Counted as usual; salaried from the employment letter, variable income on a two-year average | Employment letter, pay stub, two years of Notices of Assessment |
| Child or spousal support you receive | Counted by many lenders when set out in a signed agreement or court order; some want a few months of proof it is actually being paid; some gross up non-taxable child support | Separation agreement, bank statements showing deposits |
| Support you pay | Treated as a monthly debt in TDS, or deducted from income | Separation agreement |
| Canada Child Benefit | Some lenders count it, usually only while the children are young enough to keep it for the term | Recent CCB notice and deposits |
| Joint debts staying in your name | Counted in TDS until paid out, often from buyout proceeds | Statements; agreement terms |
Timeline and traps specific to separation files
The separation agreement comes first. Lenders will not fund a buyout off a draft, an email or a verbal deal. If negotiations are dragging, you can get pre-qualified so you know what is affordable before you agree to a number, which strengthens your position with your lawyer.
Breaking the joint mortgage can cost a penalty. If the existing mortgage is fixed and mid-term, paying it out triggers the greater of three months' interest or the IRD. Some current lenders let you add the buyout money to the existing mortgage with a blended rate, avoiding the penalty; others will not. Compare the cost of staying versus moving with the renewal and penalty calculator, and see how IRD penalties are calculated.
Coming off title is not the same as coming off the mortgage. Your former partner needs to be released from the mortgage covenant too, which normally happens when the old mortgage is paid out. An assumption, where you take over the existing mortgage alone, is possible with some lenders if you qualify alone.
Land transfer tax and legal fees. Transfers between spouses under a separation agreement are generally exempt from Ontario land transfer tax, but your real estate lawyer confirms the exemption and files it. Budget about $1,850 for legal, title insurance and disbursements, plus the appraisal.
Both spouses have rights to the matrimonial home in Ontario regardless of whose name is on title. Lenders rely on the agreement and your lawyers to deal with those rights, so do not try to refinance quietly before the agreement is signed.
Steps to keep the home
- Get a pre-qualification on your income alone. Before you settle the buyout amount, know the largest mortgage you can carry at the stress-test rate. Start at pre-approval.
- Order or estimate the value. An appraisal sets both the equity being split and the loan-to-value the lender uses.
- Get a payout and penalty statement from the current lender, and ask whether it offers a blend or an assumption.
- Sign the separation agreement with the buyout amount, support terms and the departing partner's agreement to come off title.
- Submit the full file: agreement, income documents, proof of support received, appraisal and debt statements.
- Close through your real estate lawyer, who pays out the old mortgage, pays the buyout, registers the new mortgage and handles the title transfer.

Frequently asked questions
Can I refinance above 80% to buy out my ex-spouse?
Sometimes. Ordinary refinances are capped at 80% of the home's value, but some default insurers and lenders offer spousal buyout programs that treat the transaction more like a purchase and can go higher, in some cases up to 95%. They usually require a signed separation agreement, a principal residence, and proceeds used only for the payout and buyout set out in the agreement. A default insurance premium applies.
Does child support count as income for a mortgage?
Many lenders count child and spousal support you receive if it is set out in a signed separation agreement or court order, and some want proof that payments have been received for a few months. Some lenders gross up child support because it is not taxable. Support you pay is treated as a debt.
Do I pay land transfer tax when I buy out my spouse?
Transfers between spouses under a separation agreement or court order are generally exempt from Ontario land transfer tax. Your real estate lawyer confirms whether the exemption applies to your situation and files the required statements.
Can I get a buyout mortgage before the separation agreement is signed?
You can get pre-qualified so you know what you can afford, but lenders will not fund a buyout without a signed agreement. The agreement sets the buyout amount, the support terms and the departing partner's consent to come off title, all of which the lender relies on.
What if I cannot qualify on my income alone?
Options include a co-signer, a larger share of equity being left in the home (a smaller buyout), a longer amortization on a conventional file, or a credit union or alternative lender that allows higher ratios for a short term. Each carries trade-offs in cost, and none is guaranteed until a lender issues a commitment.
