You owe all of it. What happens to an overdraft on a joint account when one person dies is, bluntly, nothing: it does not split in two, and the bank does not write off a share. Both holders of a joint account are liable for the whole overdrawn balance, so the survivor is now liable for every penny of it, on what is usually about half the household income.

The wording in the account terms is jointly and severally liable. Joint means the bank can treat you as a pair. Several means it can treat each of you separately, in full, as though you alone had run the account into the red. It gets to choose which route it uses, and after a death there is only one living person to ask.

There is a second thing about an overdraft that a personal loan does not do, and it is the part that catches people out in week three. An overdraft is repayable on demand. It has no term, no fixed monthly payment and no protection from being pulled. When the bank is told a holder has died, it reviews the facility — and reducing or withdrawing it is a normal outcome, not a punishment.

At a glance

  • The survivor owes 100% of the overdrawn balance, not half. Death does not reduce it.
  • A credit balance passes to the survivor by survivorship. A debit balance stays with them in full. It works in both directions.
  • The account normally continues in the survivor's sole name, carrying the overdraft with it.
  • The bank will usually review the facility on notification and may cut or remove it, because the income behind it has changed.
  • Most bank terms include a right of set-off, so money in your other accounts at the same bank is not necessarily safe.

The short answer, and why it works in both directions

Everyone knows the first half of the joint account rule: if there is money in the account when one holder dies, the survivor keeps it. The balance passes by survivorship, outside the will, without waiting for probate. That is the reassuring half, and it is the half that gets repeated.

The second half is the same rule seen from the other side. The account is one account, held by two people who are each responsible for the whole of it. If the account is in credit, the survivor takes the whole credit. If it is overdrawn, the survivor keeps the whole debt. Nothing about the arrangement was ever a half-and-half split. It only looked that way because two people were paying into it.

So the position the morning after is straightforward and unwelcome. The account continues. The overdrawn balance is unchanged. Interest and any fees continue to be charged on it in the ordinary way. Once the bank has seen the death certificate it will normally put the account into the survivor's sole name, and the overdraft comes along with it.

This is the same principle that means a surviving joint mortgage borrower owes the entire mortgage balance rather than half of it. It is not specific to overdrafts, and meeting it twice in the same month is a common and horrible experience.

Why an overdraft is worse than a loan here

A personal loan is a fixed agreement. There is a balance, a rate, a term and a monthly payment, and the lender cannot simply decide it wants everything back next Tuesday unless the agreement has been broken.

An overdraft is not like that. It is a facility on a current account, repayable on demand, and the bank can reduce it or withdraw it after giving notice under the account terms. In normal life this almost never matters, because nothing prompts the bank to look at it. A death does prompt a look. The bank has just been told that one of the two people whose income supported the facility is no longer there, and it has to decide whether the arrangement is still appropriate.

The practical consequences worth understanding in advance:

  • The limit may be cut, which can push a balance from within the agreed limit into an unarranged overdraft, where charges are higher.
  • The facility may be withdrawn altogether, with the balance becoming immediately repayable.
  • Payments that were relying on the overdrawn headroom — the mortgage direct debit, the council tax — can start to bounce.
  • A bounced payment produces an arrears letter from the organisation at the other end, which knows nothing about the death.

This is why an overdraft deserves a phone call in the first fortnight rather than the fourth month. Almost every bank has a bereavement team, and they are usually the most humane part of the organisation. What they can offer is time and a managed reduction. What they cannot offer is forgiveness.

What the bank does the day it is told

The sequence is broadly the same across UK banks.

  • Any card issued to the person who died is cancelled, along with their online and telephone banking access.
  • Their authority over the account ends. Anything they had set up personally, and any payment relying on their card details, needs checking.
  • The account is reviewed and usually transferred into the survivor's sole name once the death certificate has been provided.
  • The overdraft facility is reviewed. It may be left alone, reduced, or withdrawn with notice.
  • Accounts held in the deceased's sole name are frozen. That is a separate process, and it is where most of the household's payment failures actually come from.
  • Any money paid in after the date of death that belonged to the deceased — a pension instalment, a benefit payment — is likely to be reclaimed from the account.

That last one is worth bracing for. Money can appear and then disappear from an overdrawn account within a fortnight, deepening the overdraft rather than easing it. Pension and benefit payments stop at the date of death, and anything paid after it is normally recovered.

Other things stop at the same time and change the household budget in ways nobody anticipates. Where a car was provided through the Motability Scheme for the person who died, it has to go back, as set out in what happens to a Motability car when the disabled person dies. A household can lose the overdraft headroom and the transport in the same month.

There is one more thing the bank may do, and it is the one nobody expects. Most bank and building society terms include a right of set-off: the ability to take money from one account you hold with them and use it to reduce a debt you owe them on another. Because you are severally liable for the whole of the joint overdraft, a bank may seek to apply money from your own accounts with it against that overdrawn balance.

Two things are worth knowing before your salary lands.

First, banks do not all apply set-off in the same way, and the position when the accounts are in different combinations of names is not as simple as their terms make it sound. Ask the bank directly what it intends to do and get the reply in writing rather than discovering it when the rent bounces.

Second, there are protections you can invoke. A bank is not supposed to leave a customer without enough money for essentials — rent or mortgage, energy, food — and if it has, say so, in writing, and ask for the money to be returned. Free debt advisers routinely use a customer's right to tell a bank which payments incoming money must be used for, and will often suggest that income, particularly benefits income, is received into an account at a completely unconnected bank while a debt is being sorted out. StepChange, Citizens Advice and MoneyHelper all cover this and none of them charges.

If a bank behaves unreasonably — taking money that left you unable to eat, or withdrawing a facility with no notice at all — complain to the bank first and then to the Financial Ombudsman Service, which is free to use.

One income, and the same overdraft

This is the part that does the real damage, and it is arithmetic rather than law.

A permanent overdraft in a two-income household is usually not a crisis. It is a gap that gets bridged every month: the account dips towards the limit in the last week and recovers on payday. Two salaries make the recovery happen. One salary often does not, so the balance stops recovering and starts drifting towards the limit and then past it, where the charges are higher and the pressure is worse.

At the same moment, the fixed costs mostly stay where they were. The mortgage or rent does not halve. Council tax may fall if the survivor becomes the only adult in the property, and it is worth claiming that promptly, but the energy standing charge, the broadband, the insurances and the car do not care how many people live there now.

The honest way to deal with this is to work out the new monthly position on paper before deciding anything, and to do it early, while there is still an overdraft rather than an arrears file. If the number does not work, the options are the ordinary ones: reduce the outgoings, ask the bank to convert the overdraft into something with a fixed repayment over a longer period, and get free advice. What is almost never a good idea is replacing the overdraft with high-cost secured borrowing — a logbook loan against the car solves a month and creates a year.

Can you claim half from the estate?

You can ask, and it is worth asking, but understand what you are asking for.

The deceased's share of the overdraft is a debt of their estate, and the executor should list it as a claim. If the estate has money left once the funeral, the administration costs and any secured debts have been dealt with, a contribution towards the balance is realistic. Write to the executor early and ask for the claim to be recorded before anything is paid out to beneficiaries, because chasing money back after it has been distributed is a great deal harder.

Where the estate cannot pay everything it owes, a strict statutory order applies and unsecured lending sits well down it — the sequence is set out in who gets paid first when an estate owes more than it owns. In that situation you may receive nothing at all from the estate and still owe the bank the whole overdrawn balance.

Nothing obliges the bank to wait while any of this happens. In practice, most survivors repay or restructure the overdraft first and pursue the estate afterwards, if at all.

It helps to be clear about which debts are actually yours and which are only claims against the estate, because collection letters rarely make the distinction. A spouse is not personally liable for a partner's own credit card simply by virtue of being married, as explained in whether you are liable for a wife's credit card debt after death, and the same logic applies to instalment plans, covered in what happens to Klarna debt when someone dies. A joint overdraft is genuinely yours. Many of the other letters are not.

What to do this week

  • Tell the bank, and ask for the bereavement team. Send the death certificate. Ask in the same conversation what will happen to the overdraft facility.
  • Ask for the limit to be held, in writing. A short written agreement not to reduce the facility for an agreed period is far better than an assurance on the phone.
  • Check what is scheduled to leave the account. Anything essential should be moved to a date just after income arrives, not just before.
  • Check where your income lands. If it arrives into the overdrawn account, understand that it reduces the overdraft rather than being available to spend.
  • Claim the single person discount on council tax and check entitlement to any bereavement support. Both take minutes and neither is automatic.
  • Get free debt advice before agreeing a repayment plan, not afterwards. A plan agreed under pressure in the first month is often the wrong one.
  • Keep every letter. If a complaint becomes necessary later, the paper trail is what wins it.

If you are reading this before it happens

A persistent joint overdraft is one of the few household debts that is invisible until someone dies, because it never generates a bill. It is worth knowing what it would mean.

Clearing it, or converting it into something with a fixed end date, removes the problem entirely. Where that is not realistic, level term life cover is the usual way of making sure a survivor is not left carrying a household's borrowing on one income. Set up properly — written in trust, or with the surviving partner named as beneficiary — the money is paid to that person rather than into the estate, so it does not queue behind the estate's creditors or wait for probate. That distinction matters more than people realise, and the risk of getting it wrong is set out in whether a life payout goes to creditors instead of the family.

Nobody can promise that an application will be accepted or that a particular claim will be paid: cover depends on age, health and underwriting, and it has to be in place before it is needed. If a diagnosis has already been given, the options narrow but do not always disappear, and the sequence for a couple in that position is set out in what a terminal diagnosis means for a joint mortgage and keeping the home. Otherwise you can get life insurance quotes through an FCA-authorised broker and see what is available.

Scotland and Northern Ireland

The liability rule is the same across the UK. A joint account holder is liable for the whole overdrawn balance in Glasgow exactly as in Cardiff. What differs is what happens if it is not repaid, and how the estate side is handled.

In Scotland a creditor raises a court action for a decree rather than a county court judgment, and enforcement is carried out by sheriff officers through diligence, such as an earnings arrestment or a bank arrestment. Scotland also has its own statutory debt solutions, including the Debt Arrangement Scheme, which can stop interest and charges while a plan runs, and the grant needed to administer an estate is called confirmation rather than probate.

In Northern Ireland judgments are enforced through the Enforcement of Judgments Office rather than by bailiffs, grants are issued by the Northern Ireland Courts and Tribunals Service, and locally specific money advice is signposted from nidirect.

Frequently asked questions

Who owes a joint overdraft when one account holder dies?

The survivor owes all of it. Joint accounts carry joint and several liability, so each holder is responsible for the full overdrawn balance rather than a half share. The bank will look to the surviving holder first, because that is the simplest route to being repaid, and it is under no obligation to claim against the estate before it does so.

What does the bank do when it is told one holder has died?

The account usually continues in the survivor's sole name, but the bank reviews the overdraft and often reduces or withdraws it, because the household income behind it has changed. The deceased's cards and any authority they held are cancelled, so standing orders and anything relying on their card details should be checked immediately. Accounts in their sole name are frozen separately.

Can I claim the other half from the estate?

You can ask the executor to treat a share as a debt of the estate, and it may be paid if there is money left after the funeral, the administration costs and any secured debts. Nothing obliges the bank to wait while that happens, so you may find yourself repaying the overdraft first and claiming from the estate afterwards, or not recovering anything at all if the estate is insolvent.
