A joint mortgage does not end when your marriage does. Almost every joint mortgage in England and Wales is a joint and several contract, which means each of you is liable to the lender for the full monthly payment, not half of it, until the loan is repaid, transferred into one name or replaced. Moving out changes nothing, and a private deal about who pays binds neither the lender nor your credit file.
This guide covers who should pay while you are separated, what the mortgage does to your credit score, the remortgage route to buying out your ex, how a lender re-tests affordability on one income, and what actually happens if payments stop. Before you negotiate over the house at all, it helps to know what share of the total assets is realistically yours: the settlement range estimator gives you a starting range for your split, which tells you quickly whether a buyout is affordable or the family home will have to be sold.
Joint and several liability: divorce does not split the debt
Joint and several liability means the lender can demand the entire payment from either borrower. There is no such thing as your half of a joint mortgage as far as the bank is concerned: if £1,200 is due and only £600 arrives, both of you are in arrears. The government's guidance on money and property when a relationship ends is blunt about this: you remain responsible for the mortgage together until the loan itself changes.
Crucially, the lender is not a party to your divorce. A financial settlement, even one sealed by the court, divides the asset between you; it does not amend the loan contract. If the order says your ex pays and they stop, the lender pursues you both. Only a sale, a remortgage or a lender-approved transfer of equity actually releases a name.
Who pays the mortgage during separation and divorce
Between separating and settling, agree an interim arrangement and put it in writing: carry on splitting it, the person staying pays, or the higher earner covers it. What matters to the lender is only that the full amount arrives on time. Two principles keep interim arrangements fair. First, who pays does not decide who owns: paying the mortgage alone for a year does not transfer your ex's share to you, though contributions can be raised in the financial settlement negotiation, so keep records. Second, if the person who left stops contributing and you cannot cover the payment, interim spousal maintenance can be sought from a higher-earning spouse; note that maintenance is not taxable income for the recipient and not deductible for the payer.
Tell the lender early. Most have teams for separating borrowers and can discuss short-term options. And if the home is in your spouse's sole name rather than joint names, register your home rights with the Land Registry so it cannot be sold or remortgaged over your head.
Joint mortgages, credit scores and divorce
A joint mortgage creates a financial association on your credit file, so lenders assessing you will also consider your ex's credit behaviour. Any missed or late payment on the joint account is recorded against both of you and stays visible for 6 years. Separation is precisely the wrong moment to pick up arrears, because the whole buyout route depends on one of you passing a fresh mortgage application with a clean file. Formal payment holidays can also be flagged to credit reference agencies, so treat them as a last resort rather than a convenience. Once the joint account closes, ask the credit reference agencies to break the association.
Remortgaging to buy out your ex and keep the family home
The standard route to keeping the house is a transfer of equity combined with a remortgage: a new mortgage in your sole name repays the joint loan and raises the cash to buy your ex's share, and their name comes off the loan and the title in one transaction. The mechanics, timescales and legal costs are covered in our guide to house buyouts and transfers of equity. The arithmetic looks like this:
- Home value £320,000, joint mortgage outstanding £180,000, so equity of £140,000.
- An equal division gives each spouse £70,000 of equity.
- The person staying remortgages for £250,000: enough to repay the £180,000 loan and pay the £70,000 buyout. That is a 78 percent loan to value, in one name.
Two costs to check before committing. If you are mid-way through a fixed deal, an early repayment charge of typically 1 to 5 percent of the balance may apply, though a transfer of equity with your existing lender can often keep the product running and avoid it. And whatever you agree should be recorded in a consent order (court fee £62) so the buyout figure and the remortgage deadline are binding; see our guide to consent orders and clean breaks.
| Option | What happens to the joint mortgage | Watch out for |
|---|---|---|
| Sell and split | Repaid from the sale proceeds; both borrowers released | Early repayment charges mid-fix; agreeing the division of net proceeds |
| Buyout by remortgage | New sole-name mortgage repays the joint loan and funds the buyout | Sole affordability check; early repayment charge if you switch lender mid-deal |
| Keep it running jointly | Both stay liable, often with one occupying, sometimes under a Mesher order until a trigger event | The leaver's borrowing power stays tied up and their next purchase can attract the 5 percent additional-dwelling SDLT surcharge |
| Court decides | The court can transfer the home or order a sale in financial remedy proceedings | Form A fee of £321, plus time and costs; the court still cannot force the lender to release a borrower |

The affordability reassessment behind every financial settlement
The lender treats a buyout as a brand new application, underwritten on one income against the full new balance. Loan sizes are typically capped around 4.5 times salary, so the £250,000 remortgage above needs roughly £56,000 of sole income before maintenance is considered. Outgoings count too: child maintenance you pay reduces what you can borrow, while spousal or child maintenance you receive can often be counted as income where it is backed by a court order or CMS arrangement and a track record of payments. If the sums do not work, ask about longer terms, check whether maintenance can be evidenced properly, or accept that the settlement needs a different shape, such as offsetting the house against a pension. This is the single most common point where a settlement that looks fair on paper fails in practice, so test affordability before you agree figures, not after.
Arrears, default and losing the family home
If payments stop, the lender writes to both borrowers, arrears fees and interest accrue, and the arrears are recorded on both credit files. Persist and the lender can seek a possession order through the courts and sell the property; if the sale does not clear the debt, the shortfall remains a joint and several debt it can pursue against either of you. None of this is softened by whose fault the missed payments were. If arrears are looming, contact the lender before missing a payment: forbearance options such as a temporary switch to interest-only are far easier to agree early, and an orderly sale on your own timetable will almost always recover more equity than a forced one.
Tax when the family home changes hands
Transfers between divorcing spouses are treated gently, but only within limits. For Capital Gains Tax, transfers happen at no gain no loss for 3 tax years after the tax year of separation, and without time limit where they are made under a court order, under section 58 TCGA 1992 as extended by Finance Act 2023. Miss the window without an order and the leaver can face residential CGT at 18 or 24 percent with a 60-day reporting deadline. Stamp Duty Land Tax is usually no issue: HMRC's guidance on property transfers confirms transfers made under a divorce agreement or court order are exempt. The trap is the next purchase: buy a new home while your name is still on the old one and the 5 percent additional-dwelling surcharge can bite. Our Capital Gains Tax and divorce hub covers the timing rules in detail.
Settle the mortgage inside your financial settlement
The joint mortgage is where the legal settlement and the practical money meet: liability is joint and several until the lender releases a name, the payment record you protect now is the credit file your buyout depends on, and every buyout stands or falls on a sole-income affordability test. Deal with the mortgage inside the settlement, with deadlines and fallbacks in a consent order, not as an afterthought once the divorce is done. If you are working out whether keeping the home is realistic, our page for divorcing homeowners brings the property, tax and settlement issues together, and a specialist can sanity-check the buyout figures and deadlines before the consent order is drafted; reach us via the contact page.
