Divorce forces a lot of hard decisions. And when children are involved, some of those decisions aren’t about money at all — but instead, keeping life as stable as possible for the people who matter most.
Take the hypothetical story of Tom and his ex-wife Amy as an example. After an amicable split, they decided to keep the family home so their two young children wouldn’t experience the disruption that moving would entail. Tom relocated to a nearby rental. Amy earns income through side hustles that don't give her the kind of steady, verifiable paycheques that lenders look for, so Tom kept the mortgage in his name — with Amy reimbursing him each month as she gets paid.

It’s worked out fine so far. But now Tom wants to buy a condo and he’s hitting a wall: even though Amy is covering the mortgage payments, his name is on the home loan, and lenders can’t ignore it.
Why your ex’s mortgage is still your problem
Here’s the part that catches a lot of divorced people off guard: as long as your name is on a mortgage, you’re legally responsible for it. The language in your separation agreement and who’s actually making the payments make no difference. The lender will treat that debt as yours until your name is off the loan, according to Loans Canada (1).
This can directly affect your ability to borrow more money. When you apply for a new mortgage, lenders calculate your Total Debt Service (TDS) ratio: essentially, the percentage of your income that goes toward all your debts combined, including mortgages, car loans and credit cards. If your name is on a mortgage you’re not paying, that obligation still gets counted, which makes your debt load look higher than it really is.
Lenders generally want your TDS ratio to stay below 44% (2). On paper, Tom’s ratio includes a mortgage, which could push him over that threshold and either reduce how much he can borrow or make it harder to qualify for more financing at all.
Child support payments add another layer of complexity. If you’re paying support to the custodial parent, those count against your TDS ratio the same way a car payment would — further reducing your borrowing power.
How much home can you afford?
Whether you're hunting for a new home or looking to refinance your mortgage, knowing how much your new loan might cost you is critical. Use our handy mortgage calculator to help you understand what your payments could look like.
Get StartedCan a separation agreement help?
A legally binding separation agreement that clearly assigns the existing mortgage to your ex is an important step, as lenders will want to see how payments are distributed between you two. Bank statements showing regular, consistent reimbursements from your ex also help strengthen your application.
But there’s still no guarantee you’ll get approved. Even with documentation in hand, many lenders will continue to treat you as legally liable for the debt until your name is removed from it (3). The separation agreement protects you in family court — but it doesn’t change what the lender sees on paper.

That said, some lenders will allow support payments to be deducted from your gross income rather than added to your liabilities, which is a much more favourable calculation that can significantly improve your borrowing options (4). A mortgage broker who specializes in post-divorce financing can be invaluable here, as they’ll know which lenders take that approach.
The best solution? Get your name off the mortgage
The most straightforward path to financial freedom for both Tom and Amy is to refinance the mortgage — removing Tom’s name and making it solely Amy’s responsibility.
Refinancing generally costs between 1% and 3% of the remaining mortgage balance, depending on whether you’re breaking the mortgage mid-term and what kind of prepayment penalties apply (5). It’s not free, but it gives both parties a clean break.
The catch for Amy is, she’ll need to qualify to refinance on her own. To do so, she’ll need to show a consistent, documented income over at least 12 months. The good news is that this can include spousal support and child support payments, provided they’re clearly outlined in the separation agreement and are regularly paid (6). Lenders will want to see regular bank-to-bank transfers with no missed payments. Cash doesn’t count in this case.
If Amy can’t qualify alone, another option is to find a cosigner, such as a family member, who can help her take over the mortgage. Some lenders also offer a Spousal Buyout Program that allows refinancing up to 95% of the home’s value, rather than the usual 80%, specifically to help separating spouses manage this transition (7).

What this means for Tom
Until Amy refinances and takes the mortgage over, Tom’s options for buying a condo are limited but not necessarily zero.
A mortgage broker can help him find lenders who will take his separation agreement and reimbursement history into account. Some lenders are more flexible than others when it comes to how they treat shared obligations post-divorce. Going in with clear documentation — a solid separation agreement, bank statements showing payments being made and a clear picture of his financial situation — gives Tom the best shot at qualifying for financing.

Broadly speaking, keeping the mortgage in Tom’s name was only intended to be a temporary arrangement. The sooner both parties can move toward a clean separation of their finances, the better positioned they’ll each be to move toward full independence.
Bottom line
Keeping the family home after divorce can be a genuinely good decision, especially for any children you may have. But with that comes financial obligations that can follow you around longer than expected. If your name is on a mortgage, lenders will count it against you, regardless of who’s actually paying it.
The path forward involves a combination of solid documentation, the right lender and, eventually, a refinance that puts each person’s finances fully in their own hands. It’s not always a quick fix, but it’s the clearest route to financial independence for both sides.
If you’re navigating a situation like Tom’s and Amy’s, talk to a mortgage broker experienced with post-divorce refinancing as the next best step to moving forward in your life.
