Who this is for: Separated or divorcing owners who want to keep the home, have a figure agreed or ordered for the other person's share, and can afford the debt on one income.

Separation is hard enough without a mortgage decision in the middle of it. Often one person wants to keep the home, especially where children are settled in the neighbourhood, and the other needs their share in cash. The buyout is the bridge. A second mortgage is one of the tools used to build it, and it should be a late step, not the first one.
What a buyout with a second mortgage is
A buyout means one owner pays the other for their share of the home so that only one name remains. Money for that payment can come from savings, a refinance, a family loan, a sale of other assets or a new loan. A second mortgage is a loan registered against the home behind the existing first mortgage. The Financial Consumer Agency of Canada says second mortgages typically have higher rates than first mortgages, and that you must keep paying the first one too.
What you owe your former partner is a separate question, and the lender does not decide it. In Ontario, for married spouses, the province explains that equalization generally shares the difference in each spouse’s net family property equally, with some exclusions. Other provinces have different rules. A lawyer or a signed agreement sets the number the loan needs to cover.
When it makes sense
It makes sense when you have a settled figure, a lawyer’s advice, and an income that can carry the whole home on its own. The first mortgage should stay in place on terms you can keep, for instance a rate you do not want to lose, while the second mortgage covers the payout.
It also fits when a bank has said no to a full refinance because of how your income is documented, how recently you separated, or support payments that lenders count in different ways. A private lender looks mainly at equity, and the bank’s rules may block what a private lender can allow.
Time can matter too. A court or an agreement may set a date for the payment, and a second mortgage can sometimes be arranged within that window.
When it makes things worse
It makes things worse when the figure is still being argued. A loan taken out against a number the other person has not accepted can leave you with fees and interest and no deal.
It makes things worse when your income alone cannot carry the home. Two incomes paid the debts before. If one income now has to cover the first mortgage, the second mortgage, tax, insurance and daily costs, a missed payment becomes likely, and the home you fought to keep is the home at risk.
It also goes wrong when you use the loan to avoid a conversation about selling. Sometimes the most affordable outcome for both people is to sell the home and split the proceeds. A lawyer can tell you whether that makes more sense for your situation.
What it really costs
The two worked examples above run from the legal figure to the loan. The first shows how an equalization payment is calculated using the method the Government of Ontario describes. The second shows that borrowing $150,000 for a year costs $25,000 on made-up assumptions, and that the $150,000 remains owing. Per the same agency, add costs for appraisal, title search, title insurance and legal fees.
Compare that with the alternatives. A refinance of the whole first mortgage may carry a lower interest rate on the entire balance, though it may also carry a penalty for breaking the existing mortgage. Use the calculator with real quotes and read the page on equity takeout refinances before you decide.
Legal costs are real too: a separation agreement, the transfer of title, and independent legal advice for each person. Ask your lawyer to estimate them with the buyout.
The risk to the home
The home is security for the new loan as well as the old one. The agency says that if you cannot repay a home equity loan you may face serious consequences, including foreclosure. After a separation your income is likely lower and your costs higher, and the home carries a bigger debt than it did.
There are also legal risks of getting the order wrong. If your ex is still on title or the mortgage, a missed payment can affect them too, and that can reopen a conflict. A lawyer makes sure that title is transferred and any release is completed when the money moves.
Keep paying the first mortgage on time. A default on the first loan can bring action on the whole property.
Options to try first
Start with a family lawyer or a mediator, before any lender. They can confirm what is owed, whether the home must be sold, and how support is treated. Then ask your bank about a refinance. A bank will tell you what income it will count, including support payments.
Other options to consider: a family member’s loan with a lawyer-drafted agreement, selling other assets to raise the payout, structuring a payment over time in the separation agreement, or selling the home. Each carries costs, and each should be compared against a loan that costs thousands in fees.

How the exit works
Most private second mortgages are short, and the balance is due at the end. Decide how it ends before you sign. The usual plan is a refinance with a bank once your single income has some history. A bank will look at your credit, your income and the appraised value then, so build the plan around a worse case than today’s.
Ask what it costs to extend and what happens if you are late. If the plan is to sell, write down the date by which you will list the home.
What to ask before you sign
- That your lawyer has confirmed the amount owed and the deadline for it.
- The total cost of borrowing in dollars for the full term, with every fee shown.
- What you will still owe on the last day, and the cost to extend.
- Whether your former partner must sign a release, and who pays the legal fees.
- What happens if your income drops.
- The name of the licensed professional and how to check their licence with your provincial regulator.
Rules differ by province, and Quebec uses a different system from the common-law provinces. If you want to talk to a licensed mortgage professional after you have legal advice, you can check your options. You are free to say no.
How a $150,000 equalization payment is worked out
Made-up figures only, following the method the Government of Ontario describes: compare what each spouse has, subtract the smaller from the larger, and divide the difference by two. Real calculations involve debts, dates and exclusions, so a lawyer must do the real one.
- Spouse A's net family property
- $500,000
- Spouse B's net family property
- $200,000
- Difference
- $300,000
- Equalization payment from A to B
- $150,000
$500,000 minus $200,000

Questions people ask
How much do I owe my spouse for their share of the home?
That is a legal question, and the answer depends on your province, how long you were together and what you each owned. In Ontario, married spouses usually equalize the value of what each acquired. A family lawyer or a signed separation agreement sets the figure, not a mortgage lender.
Do common-law partners have to buy each other out?
Not under Ontario's equalization rules, which the province says do not require common-law couples to split property acquired together. Each person generally keeps what they bought, though contributions can be claimed. Other provinces differ, so get advice where you live.
Can a lender make me remove my ex from the mortgage?
A buyout normally replaces the existing mortgage or adds a new loan so that the departing person is no longer on title. Whether your lender will do that depends on your income and the property. A lawyer handles the transfer and release so it is clean.
How long do I have to settle the property question?
Time limits apply, and they differ by province. In Ontario the government says you have six years from separation or two years from a final divorce to ask a court to decide an equalization payment, whichever comes first. Check your own deadline early.
Can I buy out my ex using only a second mortgage?
Sometimes, if the first mortgage can stay in place and the loan fits your income and equity. Often a refinance of the first mortgage is cleaner because it can remove the other person's name. Ask a licensed professional to compare both on cost.
What if my ex and I cannot agree on the home's value?
An independent appraisal gives both of you a starting figure, and a lawyer or mediator can help with disputes. Do not borrow against a number the other person has not accepted, because the loan and its fees come due whether or not you agree.
