Keeping the house after a separation
The mortgage question usually arrives in the middle of a hard year, and it is frequently answered wrongly — by a bank that treats it as an ordinary refinance and stops at 80%. It is not an ordinary refinance, and the difference decides whether the house can be kept.
Can I buy out my ex-partner and keep the house?
Often, but not as a refinance. An ordinary refinance is capped at 80% of the home’s value, and a buyout usually needs more than that. Insurer programs instead treat a purchase from a co-owner as a purchase rather than a refinance, which is why it is not bound by the 80% refinance ceiling. It requires a fully executed separation agreement setting out the buyout amount and the division of property, and the departing owner removed from title on closing.
Why the bank said 80%
Here is the arithmetic that stops most of these files, on a Nova Scotia example. A home worth $480,000 with a $260,000 mortgage has $220,000 of equity. If it is split evenly, the departing owner is owed $110,000.
| Home value | $480,000 |
| Existing mortgage | $260,000 |
| Equity | $220,000 |
| Departing owner’s half | $110,000 |
| New mortgage required | $370,000 |
| That as a share of value | 77.1% |
| Maximum on an ordinary refinance (80%) | $384,000 |
| Shortfall if treated as a refinance | None |
On this particular split a refinance would reach, but push the equity share or the mortgage balance a little higher and it will not.
How it is structured instead
Where the insurer program applies, the transaction is set up as a purchase rather than a refinance, which is why it is not bound by the 80% refinance ceiling. You are, in substance, buying your co-owner’s share of a property — and a purchase is not bound by the refinance ceiling. That single structural difference is what makes the arithmetic above work.
On the maximum figure. Several websites quote a specific loan-to-value for a spousal buyout. CMHC’s current public product list, checked 2026-09-16, does not name a spousal buyout program, and no primary insurer source for a specific figure could be verified. Rather than repeat a number that cannot be sourced, this page states the mechanism — purchase, not refinance — and the maximum for your file is confirmed with the insurer and lender before you sign anything. If you are negotiating the agreement now, get that confirmation first; it is a free phone call and it sets the number you can safely agree to.
What the separation agreement has to do
The agreement is not paperwork the lender glances at. It is the document that defines what the mortgage is funding, and getting it right while it is being drafted saves an enormous amount of difficulty later. Make sure it sets out:
- The buyout amount, as a figure, and the basis for the property’s value. An appraisal the lender can rely on is better than an agreed guess.
- Who stays on title and who comes off, and the date it happens. The departing owner must be removed on closing.
- Which debts are being settled from the proceeds, if any. Some insurer programs permit joint matrimonial debts and a mortgage prepayment penalty to be included where the agreement specifies them; others restrict the funds to the departing owner’s equity alone. Silence in the agreement generally means no.
- The treatment of support payments, clearly and durably. This directly affects whether you qualify — see below.
- Who is responsible for the mortgage in the interim, which protects both parties’ credit while the transaction completes.
Nothing on this page is legal advice, and the agreement should be drafted by a Nova Scotia family lawyer. What a broker can do — usefully, and before the agreement is finalised — is tell you which numbers the financing will actually support, so that what gets signed is achievable.
Qualifying on one income
This is the constraint people underestimate. The payment two incomes carried has to pass the the greater of the contract rate plus 2% and 5.25% stress test on one, inside 39% gross debt service and 44% total debt service. On a larger mortgage than before.
Support payments cut both ways, and lenders differ more here than almost anywhere else:
- Support you pay is a monthly obligation and counts against your total debt service at essentially every lender.
- Support you receive may be added to income — but lenders want it to be durable and documented: set out in the agreement or a court order, with a history of actual receipt, and continuing for a reasonable number of years. A lender that treats it favourably can change the answer entirely.
- A co-signer or guarantor — commonly a parent — is a legitimate route where the income is genuinely short, and can be removed at a later renewal.
- Amortization. A longer amortization lowers the qualifying payment. On an uninsured mortgage most lenders allow up to 30 years.
- Credit unions are provincially regulated and set their own qualifying standards rather than applying the federal rule. In Nova Scotia that is a real alternative, not a footnote.

The Nova Scotia costs of doing it
A spousal buyout is a transfer of an interest in land, so the usual Nova Scotia closing machinery applies. Budget for legal fees of roughly $850 to $1,000 plus disbursements, recording fees of $100 per document, an appraisal, and — if the existing mortgage is broken mid-term — a prepayment penalty of the greater of three months’ interest and the interest rate differential.
Deed transfer tax treatment on a transfer between separating spouses depends on how the transfer is structured and on the municipality, and exemptions can apply. Since HRM charges 1.5% — $7,200 on this example — it is worth confirming with your lawyer rather than assuming either way. Every municipality’s rate → · Closing cost calculator →
Do this part early
The sequence that works is the opposite of the usual one. Most people finalise the agreement, then discover what the financing will support. Reversing it costs nothing:
- Before the agreement is finalised — establish what you can qualify for on your own income, and what the buyout structure will actually permit. That sets the realistic range for the negotiation.
- While it is being drafted — make sure the buyout amount, the debts to be settled and the support terms are written the way the lender will need to read them.
- On execution — the full application proceeds with the signed agreement, an appraisal and income documents.
- At closing — the departing owner is removed from title, paid out by the lawyer from the mortgage proceeds, and any specified joint debts are cleared at the same time.
Conversations about this are confidential, cost nothing, and do not commit you to anything. If the answer is that the house cannot realistically be kept on one income, you will be told that plainly — with the arithmetic — early enough for it to be useful rather than late enough to hurt.
Questions people ask
Can I keep the house after a separation in Nova Scotia?
Often, yes — but usually not through an ordinary refinance. A standard refinance is capped at 80% of the home's value, and buying out a co-owner frequently needs more than that. Insurer programs treat a co-owner buyout as a purchase rather than a refinance, which is why it is not bound by the 80% refinance ceiling, which is what makes it possible above the refinance ceiling. It requires a fully executed separation agreement setting out the buyout amount and the division of property, and the departing owner removed from title on closing.
Do I need a separation agreement before applying?
Yes, a fully executed one. The lender needs to see the agreed buyout amount and how the property and debts are divided, because that is what the mortgage is funding. Applying before the agreement is signed generally wastes everyone's time — though a broker can tell you in advance whether the numbers are likely to work, which is useful information to have while negotiating it.
How much can I borrow to buy out my ex-partner?
No published maximum is quoted on this page, because CMHC's public product list does not currently name a spousal buyout program and no primary insurer source could be verified for a specific figure. What is verifiable is the contrast: an ordinary refinance is limited to 80% of value, and a buyout structured as a purchase is not bound by that limit. The current figure for your file is confirmed with the insurer and lender before you commit to anything in the agreement.
Can I use the buyout mortgage to pay off joint debts too?
Sometimes, and it depends on the insurer and on the agreement. Where joint matrimonial debts and any mortgage prepayment penalty are specified in the separation agreement, some insurer programs permit them to be included; others restrict the funds strictly to the departing owner's equity. Because it varies, put the intended use in the agreement — it is far harder to add afterwards.
Do I have to qualify for the whole mortgage on my own income?
Yes. That is the part people underestimate. A payment that two incomes carried comfortably has to pass the the greater of the contract rate plus 2% and 5.25% stress test on one, inside a 39% gross debt service ratio and a 44% total debt service ratio — and any support you pay counts against you while support you receive may or may not count for you, depending on the lender and the durability of the arrangement.
What happens if I cannot qualify alone?
There are real options before selling: a co-signer or guarantor, a longer amortization, a lender that treats support payments more favourably, or a credit union not bound by the federal qualifying rate. Where none works, a short-term alternative mortgage can hold the property while income or credit is re-established. And sometimes selling genuinely is the better outcome — you should hear that plainly rather than be walked into a payment you cannot carry.
