When you divorce in New Brunswick, the mortgage remains a joint legal obligation until the lender formally removes one spouse, typically through a refinance or spousal buyout. Under the Marital Property Act (RSNB 2012, c. 107), the matrimonial home is divided equally (50/50), but a divorce judgment alone does not change who is liable to the bank. As of February 2026, the divorce filing fee is $110, and a CMHC spousal buyout lets the remaining spouse refinance up to 95% of the home's value.

Who Is Responsible for the Mortgage During a New Brunswick Divorce?
Both spouses named on the mortgage remain 100% legally responsible for the full debt during and after a New Brunswick divorce until the lender releases one of them. A separation agreement or court order divides the property between spouses, but it does not bind the mortgage lender. As of February 2026, the only ways to remove a spouse are a refinance, a spousal buyout, or selling the home and discharging the mortgage.
A mortgage is a contract between the borrowers and the lender, governed by contract law and not by the Marital Property Act. Even if your separation agreement states that your former spouse will keep the house and assume the mortgage, the bank can still pursue both signatories if a payment is missed. This is the single most misunderstood issue in mortgage divorce in New Brunswick. The Marital Property Act (RSNB 2012, c. 107) controls how equity is split between the two spouses; it has no power over a third-party lender. Until the lender executes a formal discharge or release, both parties' credit scores remain exposed to any missed payment, and both remain liable for the entire balance, not just half.
How Is the Matrimonial Home Divided in New Brunswick?
The matrimonial home in New Brunswick is divided equally (50/50) between spouses under the Marital Property Act (RSNB 2012, c. 107). Section 2 of the Act recognizes child care, household management, and financial provision as joint responsibilities of equal importance, so each spouse is entitled to an equal share of marital property and bears an equal share of marital debts. Both spouses have an equal right to remain in the home regardless of whose name is on the title.
Under Marital Property Act § 2, New Brunswick follows an equal-division model, not merely an equitable one. The presumptive starting point is a strict 50/50 split of net family assets, which includes the matrimonial home, household goods, vehicles, pensions, and investments. The Family Law Act (SNB 2020, c. 23) defines the marital home as property occupied as the family residence, and a spouse who is not the registered owner still holds occupancy rights. Where the home is titled in one spouse's name only, the other married spouse retains a legal right to stay and occupy the residence even if the owner objects. A spouse cannot sell, mortgage, or otherwise dispose of the matrimonial home without the other spouse's consent. Courts retain discretion to order an unequal division where a strict 50/50 split would be unfair, but this is the exception, not the rule.
What Is a Spousal Buyout and How Does It Work?
A spousal buyout lets the spouse keeping the home refinance the mortgage up to 95% of the home's appraised value to pay out the departing spouse's equity share. Unlike a standard refinance capped at 80% loan-to-value, the CMHC Spousal Buyout Program treats the transaction like a new purchase. The existing home equity serves as the down payment, so no new cash is required, and the departing spouse is removed from both the title and the mortgage.
The CMHC Spousal Buyout Program, administered through Canada's mortgage insurers (CMHC, Sagen, and Canada Guaranty), is the most common tool for removing a spouse from a mortgage in a divorce. A regular refinance caps borrowing at 80% of value and does not change ownership; a spousal buyout does both and allows borrowing up to 95% of appraised value. The maximum is the lesser of 95% LTV or the remaining mortgage balance plus the equity required to buy out the other owner and pay off joint obligations specified in the separation agreement. Spousal and child support payments can be counted as qualifying income, joint debts can be rolled into the new mortgage, and a co-signer (such as a family member) may be added if the remaining spouse cannot qualify alone. Because the loan exceeds 80% LTV, mortgage default insurance is required, and the premium is typically added to the mortgage balance.
How Do You Remove a Spouse From a Mortgage in New Brunswick?
Removing a spouse from a mortgage in New Brunswick requires the lender's formal approval, achieved through one of three routes: refinancing in one name, a CMHC spousal buyout up to 95% LTV, or selling the home and discharging the loan. A signed separation agreement clearly defining asset allocation is mandatory for the buyout program, and the remaining spouse must income-qualify for the new mortgage on approved credit, generally with a credit score of 680 or higher.
The phrase removing spouse from mortgage describes a legal release that only the lender can grant. Three paths exist in New Brunswick. First, the remaining spouse refinances the existing balance in their own name, which works if they can qualify and the balance is below 80% of value. Second, a CMHC spousal buyout extends borrowing to 95% of value, ideal when equity must be extracted to pay the departing spouse. Third, if neither spouse can qualify, the parties sell the home, discharge the mortgage, and split the net proceeds equally under the Marital Property Act. Each path requires the lender to issue a discharge or assumption agreement. A divorce judgment from the Court of King's Bench, Family Division does not, on its own, remove anyone from a mortgage contract.
What Happens With an Underwater Mortgage in a Divorce?
An underwater mortgage in a New Brunswick divorce, where the balance exceeds the home's market value, means the spouses share the negative equity equally as a marital debt under the Marital Property Act. Because section 2 makes each spouse responsible for an equal share of marital debts, neither party can simply walk away. Options include both spouses continuing payments, a short sale with lender approval, or one spouse assuming the shortfall in exchange for other concessions.
Negative equity complicates an underwater mortgage divorce because there is no equity to split, only debt. Under Marital Property Act § 2, marital debts are shared equally just as assets are, so the shortfall between the mortgage balance and the sale price is a joint obligation. A spousal buyout refinance is usually impossible when the home is underwater because there is insufficient value to support the loan. Practical resolutions include negotiating which spouse retains the home and the associated debt, arranging a lender-approved short sale (where the bank accepts less than the full balance), or offsetting the negative equity against other marital assets such as pensions or savings. A New Brunswick family lawyer can structure the separation agreement so the negative equity is allocated fairly while protecting both parties' future credit.
Can One Spouse Force the Sale of the Matrimonial Home?
Yes, either spouse can apply to the Court of King's Bench, Family Division for an order to sell the matrimonial home when the parties cannot agree on who keeps it. Because both spouses hold an equal interest under the Marital Property Act, a court may order the home listed, sold at fair market value, the mortgage discharged, and the net proceeds split 50/50. Courts weigh the best interests of any children before ordering an immediate sale.
When spouses reach an impasse over the family home, New Brunswick courts have authority to compel a sale. The matrimonial home is jointly owned in substance even if titled in one name, so neither spouse can indefinitely block the other from realizing their equal share. The court process under the Family Law Act (SNB 2020, c. 23) and the Marital Property Act allows a judge to order the home appraised, listed with a realtor, and sold, with mortgage payout and selling costs deducted before the remaining equity is divided equally. However, a judge will consider whether minor children should remain in the home for stability, and may grant one parent exclusive occupation for a defined period before sale. This balances the equal-division principle against the children's need for continuity following separation.
What Are the Costs of Keeping the House After a New Brunswick Divorce?
Keeping the house after a New Brunswick divorce involves the mortgage payout, refinancing legal fees, an appraisal, and mortgage default insurance if borrowing exceeds 80% of value. As of February 2026, transaction costs including legal fees typically range from 1.5% to 4% of the property value. New Brunswick charges a real property transfer tax of 1% of the assessed or sale value, though spousal transfers may qualify for relief.
Deciding to keep the matrimonial home carries costs beyond the buyout itself. A residential appraisal establishes the current market value, generally costing $400 to $600. Refinancing legal fees, including the discharge of the old mortgage and registration of the new one, commonly run $1,000 to $2,500. If a CMHC spousal buyout pushes borrowing above 80% loan-to-value, mortgage default insurance applies, with premiums ranging from roughly 2.8% to 4% of the loan amount, typically added to the balance rather than paid upfront. New Brunswick's real property transfer tax is 1% of the greater of the consideration or assessed value, although transfers between spouses pursuant to a separation agreement or court order may be exempt. Budgeting for these costs prevents a financially strained spouse from taking on a home they cannot sustainably afford after divorce.
What Is Mortgage Assumption in a Divorce and Is It Available?
Mortgage assumption in a divorce allows one spouse to take over the existing mortgage on its current terms, but it requires the lender's approval and is less common than a spousal buyout in New Brunswick. The assuming spouse must qualify on their own income and credit, and the lender must agree to release the departing spouse. Most Canadian lenders prefer a full refinance over assumption because it re-underwrites the loan entirely.
A mortgage assumption divorce arrangement transfers an existing mortgage from joint borrowers to a single borrower without changing the original rate or term. This can be attractive when the existing interest rate is significantly lower than current market rates, preserving favourable terms for the spouse keeping the home. However, assumption is discretionary; the lender re-qualifies the assuming spouse and can refuse if that spouse's income or credit is insufficient. Many fixed-rate mortgages in Canada are technically assumable, but lenders frequently steer divorcing couples toward the CMHC spousal buyout because it permits up to 95% LTV financing and cleanly removes the departing spouse from both title and mortgage. Always confirm with your specific lender whether assumption is permitted and what the qualification standards are before relying on this route in your separation agreement.
