The mortgage question is the one that tends to keep people awake. Can you keep the house? Can you afford it on your own? What happens if you can’t? And what on earth do you do about the mortgage you’re both still named on?
This guide answers those questions as clearly as possible. Four options, the affordability calculation, and what to do first, so you can stop lying awake with the uncertainty and start understanding what’s actually possible.
Your mortgage does not automatically change when you separate or divorce. Both names stay on it. Both parties remain fully liable for every monthly payment, regardless of who is living in the property, regardless of what your divorce agreement says, regardless of whether the lender has been told anything at all.
The lender doesn’t care about your relationship status. They care about the mortgage being repaid. Until you formally change the mortgage (by selling the property, remortgaging in one name, or another arrangement), both of you are on the hook.
This means two things:
First: If your ex stops paying their share, the lender will pursue you too. Your credit file is at risk regardless of fault.
Second: Don’t stop paying your share of the mortgage because you’re angry, or because your ex isn’t paying, or because you’ve moved out. The damage to both credit scores is real and lasting, and makes every subsequent financial step harder.
| Sell and split | One buys out the other | Mesher Order | Offset against other assets | |
|---|---|---|---|---|
| Both names removed? | Yes | Yes | No | No (at first) |
| Financial break? | Clean | Clean | Not immediately | Not immediately |
| Needs single-income affordability? | No | Yes | No | No |
| Timeline | 3–6 months | 2–4 months | Ongoing | 2–4 months |
| Best for | Neither can afford alone | One can afford alone | Children’s stability | Sufficient other assets |
The cleanest resolution. The property is sold, the mortgage is paid off from the proceeds, and whatever equity remains is divided according to your agreement.
For many couples on the Wirral, this is the most realistic option, particularly where neither party can meet the mortgage affordability test on a single income, or where the equity is needed by both people to rehouse themselves.
A worked example: A Wirral property worth £200,000 with £120,000 outstanding on the mortgage leaves £80,000 equity to divide. After selling costs (agent fees, solicitor), you’re looking at roughly £73,000–£75,000 to split between you.
Timeline: A standard estate agent sale takes three to six months. If speed is important (to reduce the time you're both liable on the mortgage, to access the equity faster, or simply to get the process finished), a cash buyer can complete in two to four weeks.
One partner takes over the mortgage in their sole name. They pay the leaving partner their share of the equity, either from remortgage funds, from savings, or from a combination.
This requires two things to work:
The remortgage: The staying partner needs to be accepted by a lender for the full mortgage in their own name. This means passing an affordability assessment based on their single income.
The transfer of equity: The legal process of removing one name from the title deeds and the mortgage. This requires a solicitor (typically £500–£1,500) and the lender’s consent. The existing lender may allow a product transfer, or a full remortgage with a new lender may be needed. Either way, check for early repayment charges on your current deal. These can be significant.
Can you afford it alone? See the next section.
A court order that postpones the sale until a trigger event, usually the youngest child leaving full-time education or the occupying partner remarrying. One partner stays in the property with the children; the other effectively waits for their share.
The occupying partner typically takes on responsibility for the mortgage payments, but critically: both names usually remain on the mortgage. That has real consequences for the non-occupying partner.
While their name is on the mortgage, the lender treats it as an active liability. This makes it significantly harder for the non-occupying partner to get a new mortgage elsewhere. Their borrowing capacity is assessed on the assumption they’re still responsible for the joint mortgage, even if they’re not making the payments.
It requires lender consent, which isn’t guaranteed. And it prolongs the financial connection between two people who are trying to separate their lives.
Mesher Orders work in specific circumstances, most commonly where the children’s stability is the overriding concern and where the non-occupying partner either has other housing options or is willing to wait. They're not a neutral option, so both parties should understand the full implications before agreeing.
One partner keeps the house; the other receives a larger share of the pensions, savings, or other matrimonial assets to compensate for their equity share.
This still requires the leaving partner’s name to be removed from the mortgage, which means the staying partner needs to remortgage in their sole name. It’s essentially the same process as Option 2, just with the payment coming from the asset offset rather than cash.
It works best when there are sufficient other assets to make the trade genuinely fair and when the staying partner can pass the affordability test independently.
This is the question at the heart of the decision for most people. Here’s how lenders assess it.
The income multiple starting point
Most lenders will lend between 4 and 4.5 times your gross annual income as a starting point. Some will go higher for borrowers with strong credit, large deposits, or professional qualifications.
If you earn £32,000, that gives a rough maximum of £128,000–£144,000. If your remaining mortgage is £120,000, you’re in the right range, but “in range” doesn’t mean “approved.” The income multiple is the starting point, not the decision.
What else counts as income?
Child maintenance and spousal support payments can count as income, but the picture is more complicated than a simple yes or no. Lenders typically need to see three months to two years of payment history, and many will only use 50–60% of maintenance income rather than the full amount. Some mainstream lenders don’t accept it at all. Child Benefit and tax credits can be counted by some lenders.
What reduces your maximum?
Every debt commitment eats into your affordability. Car finance, credit cards, personal loans and student loan repayments all reduce the amount a lender will offer. If you’re paying child maintenance as the non-resident parent, that reduces your borrowing capacity too.
The joint mortgage as a liability
If your name is still on the existing mortgage while you’re trying to get a new one, lenders will treat the joint mortgage as your liability. That can significantly reduce what you’re able to borrow for a new property, even if you’re not making the payments.
If the numbers don’t quite work
Don’t assume a mainstream lender’s decision is the end of the road. Specialist mortgage brokers who work with divorce cases know which lenders use manual underwriting (rather than automated systems), which are more flexible on maintenance income, and which will consider your future financial position once the settlement is finalised. The difference between getting a mortgage and not getting one is often about which lender you’re presented to, not your underlying finances.
If one person is buying out the other, here are the practical steps:
The whole process typically takes two to four months from instruction to completion, assuming no complications.
Your credit score and your ex’s are likely still linked, through the joint mortgage, and potentially through other joint financial products. Their behaviour affects your creditworthiness and vice versa.
Keep up with mortgage payments. Even if communication has broken down, even if your ex isn’t contributing. A missed payment is recorded against both names.
Don’t close accounts you need. Closing joint accounts mid-process can create complications. Discuss with your solicitor before making changes.
Check for financial association. Once the mortgage is resolved, apply to the credit reference agencies (Experian, Equifax, TransUnion) to remove the financial association with your ex. This prevents their future credit behaviour from affecting your file.
Monitor your own file. During and after the divorce, it’s worth checking your credit report regularly to make sure nothing unexpected has appeared.
If you’re at the beginning of this process, these are the four steps worth taking now, in this order:
Step 1: Contact your mortgage lender. Tell them the situation. Ask about your options: payment holidays, switching to interest-only temporarily, and what they'd need to see for a product transfer. Lenders would rather work with you than deal with arrears or repossession. They’re not your enemy.
Step 2: Get independent mortgage advice. A broker, ideally one with divorce experience, can assess your affordability on a single income before you commit to anything. This saves you from making a decision (like staying in the property) that later turns out to be financially unworkable.
Step 3: Get an accurate valuation. You can’t calculate equity without knowing what the property is worth. Get two or three estate agent valuations. If there’s disagreement between you and your ex, a RICS surveyor can provide an independent Red Book valuation both parties accept.
Step 4: Don’t make the mortgage decision in isolation. The mortgage is part of the overall financial settlement. A decision to remortgage in your sole name affects what happens to pensions, savings, and other assets. Talk to a family solicitor before you agree to anything, even verbally. The GOV.UK guide to staying in your home during separation covers your legal rights if you need to understand your position before making any decisions.
For a broader guide to what happens to the house in a divorce and all your options, see our guide to selling a house after divorce. The GOV.UK guidance on money and property in divorce covers the formal process for consent orders and financial remedy applications. And if your ex isn’t cooperating with decisions about the property, see our guide to what to do when your ex won’t agree to sell. If you're separating but weren't married, see our guide to selling a jointly owned property after separation.
If you both decide selling is the cleanest option, send us the details. We'll give you one realistic figure you can both work from, which helps when you're agreeing the rest of the settlement.
