How to Divide Debt in a Divorce: Who Pays What? (UK Guide)

When couples divorce, the conversation usually centres on who gets the house, how savings are split, and whether pensions need to be shared. Debts, by contrast, tend to get mentioned as an afterthought — if they're mentioned at all.

This is a serious mistake. According to available data, the average UK household carries nearly £10,000 in non-mortgage debt. Add a mortgage, car finance, and credit cards into the mix, and most divorcing couples have as much to untangle on the liability side as the asset side — sometimes more.

And here's the part that catches people out: your lender doesn't care about your divorce. A joint mortgage is a joint mortgage. A joint loan is a joint loan. If your ex-spouse stops paying their "share" of a joint debt, the lender comes after you — for the full amount. Your consent order, your separation agreement, your text messages agreeing who pays what — none of it matters to the bank. They want their money, and your name is on the contract.

This guide explains how debt works in divorce, what a consent order can and can't do about it, and how to protect yourself from ending up responsible for debts that aren't yours.

Joint Debt vs Individual Debt: The Critical Distinction

The first step in dividing debt is understanding whose name is actually on it. This determines who the lender can pursue — which is a separate question from who the court thinks should pay.

Type	Who the Lender Can Pursue	Examples
Joint debt	Either party — for the full amount (joint and several liability)	Joint mortgage, joint personal loan, joint overdraft, joint bank account
Sole debt	Only the person whose name is on the account	Credit card (primary cardholder), personal loan in one name, student loan, car finance in one name
Sole debt for family benefit	Legally, only the named person — but a court may treat it as shared	Credit card used for family holidays, loan taken out to fund home improvements

The concept of joint and several liability is the most important thing to understand about joint debt in divorce. It means that each person on the account is responsible for 100% of the debt — not 50% each. If your ex stops paying their half of a £200,000 mortgage, the lender doesn't chase them for £100,000 and you for £100,000. They chase you for the full £200,000.

This is true regardless of any private agreement between you. The lender is not a party to your divorce. They don't know or care what your consent order says. Their contract is with both of you, and that contract survives the divorce.

How Courts Approach Debt in Financial Settlements

When a court assesses a financial settlement under Section 25 of the Matrimonial Causes Act 1973, debts are considered alongside assets. The court looks at the full financial picture — what each party owns and what each party owes — and aims for a fair overall outcome.

The key factors the court considers when allocating debt include:

• When was the debt incurred? Debts taken on during the marriage are generally treated as matrimonial debts. Debts from before the marriage, or racked up by one party after separation, may be treated differently.
• What was the debt for? A loan used for family holidays, home improvements, or household expenses is more likely to be shared. A gambling debt or debt incurred for one party's exclusive benefit may be assigned to that person.
• Who has the ability to repay? The court considers each party's income and earning capacity. It won't assign a large debt to a party who has no realistic means of servicing it.
• How does the debt relate to the assets? Mortgage debt is directly tied to the property. If one party keeps the house, they typically take on the mortgage. Car finance is tied to the car. These are relatively straightforward.

Importantly, the court can order one party to take responsibility for a joint debt as part of the consent order — but this doesn't change the lender's contract. If the responsible party defaults, the lender can still pursue the other party. The consent order gives you a legal right to enforce against your ex-spouse (make them pay up), but it doesn't remove your name from the lender's books.

The Biggest Risk: Informal Agreements About Debt

The most dangerous situation is the one that feels the most reasonable: you and your ex agree between yourselves who will pay which debts, shake hands, and move on without a consent order.

Here's what can go wrong:

Scenario 1: You agree that your ex will keep paying the joint mortgage. Three years later, they lose their job and stop paying. The lender contacts you — because your name is still on the mortgage. You're now responsible for payments on a property you don't live in, and your credit score is being destroyed by arrears that aren't your fault. Without a consent order, you have no court order to enforce against your ex.

Scenario 2: You agree to take on responsibility for an £8,000 loan balance in exchange for keeping the car. Your ex agrees verbally. Six months later, you discover a joint overdraft you'd forgotten about has been maxed out. You're jointly liable for the new balance. Without a consent order closing off financial obligations, there's nothing to stop this.

Scenario 3: Your ex takes out a new loan after separation but before the divorce is finalised. If the loan was for family purposes (e.g., children's expenses), a court might consider it a matrimonial debt — meaning you could be asked to contribute. A consent order drawn up at the right time would have capped your exposure.

In every one of these scenarios, a consent order would have provided legal protection — either by formally allocating the debt (enforceable in court) or by dismissing future financial claims through clean break provisions.

How to Deal with Specific Types of Debt

Joint Mortgage

The mortgage is usually the largest debt and the most complex to handle. There are three main options:

Sell the property and repay the mortgage. The cleanest option. The property is sold, the mortgage is repaid from the proceeds, and any remaining equity is divided according to the consent order. Both parties are released from the mortgage contract.

Transfer the property (and mortgage) to one party. This requires the remaining party to remortgage in their sole name — which means they need to qualify for the mortgage on their own income. The lender must agree to release the departing party from the mortgage. This is done through a Transfer of Equity, and the consent order should include a property transfer clause and a mortgage indemnity provision (protecting the departing party if the remaining party defaults before the transfer is complete).

Keep the property jointly for a period. Sometimes — particularly when children are involved — the consent order provides for the family home to be retained until a trigger event (e.g., youngest child turns 18, one party remarries, or a specified date). This is called a Mesher Order or Martin Order. Both parties remain on the mortgage during this period, which carries ongoing risk for the non-occupying party.

Credit Cards and Overdrafts

A common misconception in the UK is that credit cards can be "joint". They cannot. A credit card always has a single primary cardholder who is 100% legally liable to the lender for the entire balance — even if the other spouse was an authorised user with their own card and incurred most of the spending.

The safest approach is to pay off and close all shared credit facilities as part of the divorce settlement. If that's not possible, the consent order should specify who takes financial responsibility for the balance — though remember, this does not alter the primary cardholder's legal contract with the card provider.

Practical steps:

• Remove authorised users from sole credit card accounts immediately to prevent further spending
• Close joint current accounts and joint overdrafts to prevent new charges being added
• Transfer balances to sole-name accounts where possible
• Notify each lender in writing that you have separated

Personal Loans (Joint)

Joint personal loans work the same way as joint mortgages — both parties are jointly and severally liable for the full balance. The consent order can allocate responsibility, but the lender's contract remains unchanged. If possible, refinance the loan into one party's sole name as part of the settlement.

Sole Debts

Debts in one person's name only are generally that person's responsibility. However, if a court determines that the debt was incurred for the benefit of the family during the marriage, it may factor that debt into the overall financial settlement — potentially reducing the debtor's share of assets to compensate.

A consent order should address sole debts explicitly — either by confirming that each party is responsible for their own debts, or by factoring specific debts into the asset division.

What a Consent Order Can and Can't Do About Debt

This distinction is critical — and most online guides get it wrong or gloss over it:

What a Consent Order CAN Do	What a Consent Order CANNOT Do
Allocate responsibility for specific debts to one party	Remove your name from a joint loan or mortgage contract
Create an enforceable obligation — if your ex fails to pay "their" debt, you can go back to court	Prevent the lender from pursuing you for a joint debt
Include indemnity clauses — protecting you if your ex defaults on a debt they agreed to pay	Override the terms of your contract with the lender
Factor debts into the overall asset division (giving the debtor a larger share of assets to compensate)	Force a lender to release you from a joint account
Dismiss future financial claims through clean break provisions	Prevent new debts being taken out by your ex after the order is made

The practical takeaway: a consent order gives you legal recourse if your ex doesn't pay — but it doesn't give you immunity from the lender. The only way to fully protect yourself from a joint debt is to have it repaid, refinanced into one name, or closed entirely.

Protecting Your Credit Score During Divorce

Your credit score doesn't know you're getting divorced. What it knows is whether payments are being made on accounts with your name on them. Here's how to protect it:

1. Keep making payments on joint debts — even if you've "agreed" your ex will take them over. Missed payments damage your credit score immediately, and the damage takes years to repair.
2. Close all joint accounts you no longer need. Joint current accounts, joint overdrafts, and authorised user cards — close or remove them as soon as practically possible.
3. Apply for a Notice of Disassociation. Paying off joint debts or divorcing does not automatically sever your credit link. You must manually contact all three credit reference agencies (Experian, Equifax, TransUnion) to request a Notice of Disassociation once joint accounts are closed, ensuring your ex-spouse’s future financial behavior no longer impacts your score.
4. Monitor your credit report regularly during and after the divorce. Check for unexpected accounts, missed payments, or new credit taken out in your name.
5. Don't take on new joint debt during the divorce process. This seems obvious, but it happens — particularly with short-term borrowing to cover legal fees or temporary housing costs.

How to Address Debt in Your Consent Order

When preparing your consent order, debts should be addressed as specifically as assets. Here's what good debt provisions look like:

• List every debt explicitly — lender name, account number (or last four digits), approximate balance, and who is taking responsibility
• Include indemnity clauses — "Party A shall indemnify Party B against all liability in respect of [named debt]" — this gives the protected party a legal right to recover from the other if the debt isn't paid
• Set deadlines for refinancing — if one party is taking over a joint mortgage, the consent order should specify a date by which they must remortgage into their sole name
• Address the mortgage specifically — include a property transfer clause if the property is being transferred, and specify what happens if the remaining party fails to remortgage by the deadline
• Factor debts into the asset division — if one party is taking on more debt, they may be entitled to a larger share of assets to compensate

The Form D81 also requires both parties to list their debts. Every liability should be included — mortgage, credit cards, loans, hire purchase, overdrafts, and any other financial obligations. The judge uses this information to assess whether the proposed settlement is fair under Section 25 of the Matrimonial Causes Act 1973.

Frequently Asked Questions

Am I responsible for my ex's debts after divorce?

If the debt is in their sole name (such as a credit card where they are the primary cardholder), generally no — the lender can only pursue the named borrower. However, if the debt is joint (joint mortgage, joint loan, joint overdraft), you remain fully liable to the lender regardless of what your divorce settlement says. A consent order can give you legal recourse if your ex fails to pay, but it doesn't remove your name from the lender's contract. The only way to fully separate is to repay, refinance, or close the joint account.

Can a court force my ex to pay a joint debt?

A consent order can allocate responsibility for a debt to one party and include indemnity provisions. If that party fails to pay, you can apply to the court to enforce the order. However, the court cannot force the lender to release you from the joint account — so you may still need to make payments to protect your credit score while pursuing enforcement against your ex.

What happens to the mortgage when we divorce?

Three options: sell the property and repay the mortgage, transfer it to one party (who remortgages in their sole name), or retain it jointly for a period under a Mesher or Martin order. Your consent order should specify which option applies and set deadlines for implementation. Until the mortgage is refinanced or repaid, both parties remain jointly liable.

Should I pay off joint debts before the divorce?

If you can, yes — it's the cleanest solution. Paying off and closing joint accounts before finalising the consent order eliminates ongoing risk. If that's not possible, the consent order should allocate responsibility and include indemnity clauses, and you should work toward refinancing or repayment as quickly as possible after the order is sealed.

Do I need to list my debts on Form D81?

Yes — all debts must be listed on Form D81, including mortgages, loans, credit cards, overdrafts, and any other financial liabilities. The judge needs the complete picture to assess whether the proposed settlement is fair. Failing to disclose debts could result in the consent order being set aside for non-disclosure.

What about debts my ex took on without my knowledge?

If the debt is in their sole name, it's their responsibility to the lender. However, if a court determines the debt was incurred for the benefit of the family during the marriage, it could be factored into the financial settlement. If you suspect your ex has hidden debts, full financial disclosure through Form D81 (or Form E in contested proceedings) is essential. A consent order based on incomplete disclosure can be challenged later.
