There is a particular phone call that debt advisers take over and over again. A woman divorced three years ago. The order said he would clear the joint loan. He stopped paying it eighteen months in. The lender is now chasing her for the whole balance, and it is perfectly entitled to.

She did nothing wrong. She just believed something that almost everybody believes, which is that a divorce settlement divides your debts.

It does not. It cannot. Here is what actually happens.

A Divorce Does Not Split Your Debts. It Splits What Is Left After Them

The court is not dividing assets on one side and debts on the other. It is looking at a net position, which is everything you own minus everything you owe, and then deciding how that single number gets shared.

That has one consequence people find counterintuitive. A debt in your name can improve your settlement, because it reduces the pot you are deemed to be walking away with. A debt in their name does the same for them. Debt is not a punishment to be allocated. It is an input.

The statutory basis for this is section 25 of the Matrimonial Causes Act 1973, which lists what the court must have regard to. Debt appears at section 25(2)(b), as "the financial needs, obligations and responsibilities which each of the parties to the marriage has or is likely to have in the foreseeable future".

Note what that wording does and does not say. It does not say the court allocates liabilities. It says the court takes your obligations into account when deciding what you need. That is a much softer instrument than people expect, and it is why two couples with identical debts can get very different outcomes.

Joint and Several Liability, and Why Your Lender Does Not Care About Your Order

This is the part that causes the damage, so it is worth being precise.

When two people take out credit together, each of them is liable for the entire balance, not for half of it. Citizens Advice puts it in one sentence: "If your debts are shared, you'll both be responsible for the whole amount - not just your half."

Your lender was not a party to your divorce. It did not agree to anything. It has a contract with two people and it will enforce that contract against whichever of them is easier to collect from, which in practice means whichever of them still answers the phone.

So a consent order saying "the respondent shall be solely responsible for the Barclaycard" does something real and something unreal at the same time. Between the two of you it is binding, and if he fails to pay you can go back to court about it. Between you and Barclaycard it is worth nothing at all.

The right-hand column is the one that decides whether you sleep at night. Which is why the only genuinely clean outcome for a joint debt is to stop it being a joint debt: clear it from the proceeds, or get the lender to move it into one name, before the order is sealed.

Lenders do not have to agree to that. Many will not. If yours will not, you need to know that before you sign, not afterwards.

Debts in One Name Only

If the credit agreement is in their name, the debt is theirs. You are not liable for it, and no amount of marriage changes that. There is no such thing as a joint credit file in the UK and no such thing as inheriting your spouse's overdraft.

What a sole-name debt does do is reduce their net worth, which can shift the settlement in their favour. That is legitimate when the borrowing was real and it was spent on the family. It is less legitimate when it was not, and this is where contested cases get ugly.

The court can take a view that borrowing was reckless, or was run up deliberately to deplete the pot, and decline to treat it as a proper call on the assets. There is no tidy test for it. It turns on evidence, which means bank statements.

What Form E Makes You Disclose

If the finances go to court, you both complete Form E, the financial statement. Debt sits at section 2.9, and the instructions are more specific than most people expect.

It excludes mortgages and overdrawn accounts, because those are captured elsewhere. It includes money owed on credit cards and store cards, bank loans, and hire purchase agreements. Then it says this: list all credit and store cards held, including those with a nil or positive balance.

Every card. Including the ones with nothing on them. The court wants to see the available credit, not just the used credit, because an unused £12,000 limit is a fact about your circumstances.

Form E also carries a duty in plain terms, that you give "a full, frank and clear disclosure of all your financial and other circumstances", and it is signed under a statement of truth. The form spells out the consequence: proceedings for contempt of court may be brought against a person who makes a false statement in a document verified by a statement of truth.

People hide debts in these forms more often than they hide assets, usually out of embarrassment rather than strategy. It is a bad idea for the same reason as hiding an asset. It gets found, and then everything else you said is in question.

The Debts That Get Forgotten

Across the cases I see, the same items get left out of the conversation until late:

• Hire purchase on the car. The car is on the asset list. The finance on it frequently is not, and a car on PCP may be worth nothing to you at all.
• Tax owed but not yet paid. If one of you is self-employed, January's tax bill is a real liability sitting in the near future.
• Family loans. Money from parents, sometimes undocumented, sometimes described as a gift when convenient and a loan when not.
• Buy now, pay later. Small individually, routinely unlisted, and increasingly not small in aggregate.
• The overdraft. Treated as normal rather than as borrowing, because it has been there for years.
• Capital Gains Tax on a transfer. Form E has its own box for this at 2.10, which is a hint about how often it bites.

None of these are complicated. They are just invisible until somebody asks.

What To Actually Do

In order, and before anything is signed:

1. Get a full picture of your own credit. Both of you, from a credit reference agency, so the conversation starts from a document rather than a memory.
2. Close or freeze joint accounts. Citizens Advice is blunt about the risk of leaving them open: "If you don't close the account your partner could access the funds or run up debts which will be your responsibility."
3. Separate the joint credit, or price the risk of not separating it. Ask the lender directly whether it will transfer the agreement into one name. Get the answer before you agree the split.
4. List every liability, including the nil-balance cards. Whether or not you end up at court, the Form E categories are a good checklist.
5. Get a financial order. Without one, nothing is final, and a divorce on its own leaves your financial claims open indefinitely.

If you are working through the rest of the money at the same time, who gets the house in a UK divorce and how pensions are split in a UK divorce are the two companion pieces, and the mortgage sits in both conversations at once. If children are involved, how child maintenance is worked out is separate from all of this and is not something the court divides. Going into mediation is often where the debt list first gets written down honestly, so how to prepare for divorce mediation is worth reading before the first session.

The Short Version

Your divorce divides the net position, not the debts. The order binds your ex-spouse to pay something; it does not release you from the contract you signed with the lender. On a joint debt you remain liable for the whole balance until the debt is gone or the lender agrees to move it, and no court can make the lender agree.

Which means the useful question is not "who should pay this?" It is "what happens to me if they stop?"

Ask that about every joint debt you have, before you sign.
