Why the bank said no
Most lenders will treat your partner’s existing mortgage as an ongoing commitment, even if he no longer lives there. That can reduce what you can borrow, because the lender assumes he could still be liable for the full payment if his ex-wife stopped paying.
It is not always a blanket “no”. It depends on how the lender assesses that existing mortgage and what evidence you can provide.
Option 1: Find a lender that assesses the existing mortgage differently
Lenders do not all treat this situation the same way. Some will reduce your maximum borrowing by the full outstanding mortgage balance. Others will treat the existing payment as a monthly commitment and run affordability on the basis of what is actually being paid each month.
Some lenders will also take a more pragmatic view if you can evidence that the ex-wife has been paying the mortgage from her own income for a sustained period, and that your partner is not contributing. It still counts as a risk, but it can change the affordability outcome.
This is where a whole-of-market broker is useful, because the “right” lender choice is often more important than the rate.
Option 2: Remove him from the mortgage now, but keep his share for later
If his ex-wife wants him off the mortgage but does not want to sell, there is a middle ground that sometimes breaks the stalemate.
In principle, she could remortgage into her sole name and remove him from both the mortgage and the deeds, while a solicitor documents that he retains an agreed interest in the property. That interest can be recorded so that it is paid out at a later point, often tied to a trigger such as the child reaching 18 or the property being sold.
This is essentially the “come off the mortgage, keep the equity” route. It is not something you do on a handshake. It needs proper legal documentation, and it usually sits alongside a formal agreement or court order.
The reality is that this only works if she can afford the mortgage in her sole name, and if there is a lender willing to do it.
Option 3: Formalise the position through solicitors, and if needed, the court
If she refuses to sell and also cannot or will not refinance, you are moving into family law territory rather than mortgage advice.
The courts can, in some cases, make orders that allow one party to remain in the home with a child and delay sale, while preserving the other party’s financial interest. These arrangements are sometimes used specifically to avoid a forced sale while children are young, but they also aim to prevent one party “walking away with nothing”.
If your partner’s concern is protecting his equity, he should take legal advice early. The longer this drifts without documentation, the harder it can be to resolve cleanly later.
Option 4: Buy together later, once the existing tie is resolved
This is not what most couples want to hear, but it is sometimes the least risky option.
If your partner stays on the existing mortgage for many years, it can keep you stuck in a cycle of reduced borrowing power and fewer lender options. You can still plan for a purchase, but it often becomes about timing, saving a larger deposit, and picking the moment when the existing situation changes.
What you should do next
You need two parallel conversations.
One is with a broker, to check whether there are lenders who will treat the existing mortgage as a monthly commitment rather than subtracting the full balance, and what evidence would be needed to support that.
The other is with a family solicitor, to understand what options exist to remove him from the mortgage while protecting his equity, and whether a formal agreement or order is the realistic route given the child and the ex-wife’s position.
Without knowing the exact figures involved it’s difficult to be more specific, and I would therefore suggest it’s worth talking in more detail. If you’d like to do so, then please call us on 023 8235 2300.
