Joint Bank Accounts and Your Will: What Passes Automatically and What Doesn't

Written by: SL, Founder, ClearLegacy · Reviewed by: ClearLegacy editorial team · Last updated: 7 November 2026

Money in a genuinely joint bank account normally passes straight to the surviving account holder when one of you dies. It doesn't wait for probate and it isn't shared out under your Will. An account in one name only is treated very differently and joint money can quietly undo a plan you thought your Will had settled.

One of the questions I hear most often comes from people who have just lost a husband, wife or partner. The funeral needs paying for, the direct debits are still going out and someone at the bank has said the word "frozen". The question is always some version of: can I still use our money?

For most couples the answer is reassuring. The bank usually needs to see a death certificate, then a joint account carries on in the survivor's name. But that simple rule has edges that catch families out. A joint account set up "just to help Mum with her bills" may not belong to the survivor at all. This guide explains how it works in England & Wales, in plain English.

Why joint accounts pass automatically

When two people hold an account jointly, the law usually treats them as owning the whole balance together rather than half each. When one of them dies, the survivor simply carries on owning it. This is called the right of survivorship.

Because the money passes by survivorship, it never becomes part of the estate that your executors deal with. That has three practical consequences:

• Your Will can't redirect it. If your Will says "I leave everything to my children" but your current account is joint with your spouse, the money in that account still goes to your spouse.
• No probate is needed for it. The surviving holder can usually keep using the account once the bank has been notified and has seen the death certificate.
• The intestacy rules don't touch it either. If there is no Will, the joint money still goes to the other account holder, whatever the Administration of Estates Act 1925 would otherwise say.

For many married couples this is exactly what they want: day-to-day money stays available when it is needed most. The same rule applies to a home owned as joint tenants, which our guide to jointly owned property and Wills covers.

What happens to an account in your sole name?

An account in your name alone is part of your estate. When the bank learns of your death, it will normally freeze the account. Nobody, including a husband, wife or partner, can use it until your executors (or, if there is no Will, your administrators) have the authority to deal with it.

Your Will then decides who receives that money. If there is no Will, the intestacy rules decide instead.

Banks do have some flexibility. Many will release money from a sole account to pay the funeral director directly, on sight of the invoice. Most will also release smaller balances without a grant of probate, although each bank sets its own limit and these vary considerably (see our guide to bank probate thresholds). Above that limit, the executors will need probate before the bank releases the money.

So if one of you holds most of the household savings in a sole account, the other could find that money unavailable for several months.

Unmarried couples: the gap that matters most

There is no such thing as common law marriage in England & Wales. However long you have lived together and whether or not you have children, an unmarried partner has no automatic right to inherit anything if there is no Will.

That makes the joint account question especially important for cohabiting couples.

• A joint account with your partner will normally pass to them by survivorship, married or not.
• An account in your sole name will pass under your Will. If you have no Will, it goes to your relatives under the intestacy rules while your partner receives nothing from it.

A surviving partner can apply to the court under the Inheritance (Provision for Family and Dependants) Act 1975 if they lived with you for at least two years before your death, but that is a stressful and uncertain process at the worst possible moment. A Will is far kinder. Our guide to Wills for unmarried couples explains how to protect each other properly.

The "convenience" joint account

This is the situation that most often leads to family disagreements.

An older parent adds one of their adult children to their bank account. The reason is usually practical: the child can pay bills, deal with the bank and step in if the parent is unwell. Nobody thinks much about what happens when the parent dies.

When the parent dies, the child is the surviving account holder and the bank will usually release the money to them. But that doesn't necessarily mean the child is entitled to keep it.

Where one person put in all the money and the other was added for convenience, the law can treat the survivor as holding the balance on trust for the estate. The money then goes back into the estate to be shared under the Will. Whether that applies depends on what the parent actually intended when the account was opened, which can be very hard to prove years later.

The result can be a painful dispute between brothers and sisters, often over a sum that the parent assumed was being shared equally all along.

If you want to give someone the ability to help with your banking without making the money theirs, there are better tools:

• A third-party mandate lets someone operate your account on your behalf while you still have mental capacity. It ends when you die.
• A Lasting Power of Attorney for property and financial affairs lets a trusted person manage your money if you lose capacity. It also ends on death.
• A clear Will then decides who inherits the money.

If you do want the joint account holder to keep the balance, say so in writing. A short letter of wishes kept with your Will, explaining what you intended, can save your family a great deal of worry.

Does joint money count for Inheritance Tax?

Yes. Passing outside the Will doesn't mean passing outside Inheritance Tax. The full rules are at gov.uk/inheritance-tax, but in brief:

• everyone has a nil-rate band of £325,000
• the residence nil-rate band of up to £175,000 can apply when a home, or a share of one, passes to direct descendants
• both bands are frozen until April 2031
• anything passing to a husband, wife or civil partner is normally exempt
• tax above the available allowances is normally charged at 40%

For a married couple or civil partners, a joint account usually causes no tax at all, because the share passing to the survivor is covered by the spouse exemption.

For anyone else, including unmarried partners and parents with adult children, your share of a joint account counts towards your estate. HM Revenue & Customs will generally look at how much of the money was really yours. If you paid everything in, the whole balance may count, even though the other account holder receives it automatically. The executors will need to include it on the Inheritance Tax forms, even though they don't control it.

Most estates in England & Wales pay no Inheritance Tax, so for many families this is a paperwork point rather than a bill. It is still worth knowing.

Debts and overdrafts on a joint account

Joint accounts come with joint responsibility. If a joint account is overdrawn, each account holder is usually liable for the whole overdraft, not just half. When one holder dies, the bank can look to the survivor to repay it.

Debts in your sole name are different. They are paid from your estate before anything is shared out. Family members don't inherit your personal debts, although they may receive less as a result. Joint loans and joint credit agreements follow their own terms, so it is worth checking any paperwork.

Can my Will change who gets a joint account?

Not directly. A Will can only deal with assets that form part of your estate. Money passing by survivorship doesn't.

If you want joint money to go somewhere other than the surviving account holder, the account itself needs to change while you are alive. That might mean:

• moving savings into an account in your sole name, so your Will controls it
• keeping a modest joint account for day-to-day spending and holding larger savings separately
• making sure your Will and your accounts point in the same direction

This matters most in blended families. Imagine a second marriage where each person wants their own children to inherit their savings in the end. If all the savings sit in a joint account, the survivor receives everything automatically and is then free to leave it to their own children. A careful Will can't fix that on its own.

A composite example

This is a composite, anonymised example drawn from common situations. It doesn't describe any real family.

Helen and Raj had lived together in Leeds for eleven years. They weren't married. Early on they opened a joint current account for bills and shopping. Raj also had a savings account in his own name, built up before they met, holding about £40,000. Neither of them had made a Will. They both assumed that, after so long together, the law would treat them as a couple.

When Raj died suddenly, the joint current account passed to Helen straight away. She could pay the bills and, because the bank released money from Raj's sole account to pay the funeral director directly, the funeral was covered.

The savings account was another matter. Without a Will, the intestacy rules sent Raj's estate to his parents. Helen received nothing from it. Raj's parents were kind and wanted to help, but agreeing what to do and the uncertainty while it was resolved added months of strain to a time that was already very hard.

A Single Will each at £69 would have let them leave their sole savings to each other. Mirror Wills for the two of them at £99 would have done the same job in one sitting.

A simple check you can do this week

Many people aren't sure which of their accounts are joint. Ten minutes finding out is time well spent.

1. List every account: current accounts, savings, ISAs, Premium Bonds, building society books and any business accounts. ISAs and Premium Bonds can only ever be held in one name.
2. Note whose name each is in: sole or joint (and if joint, with whom).
3. Ask what should happen to each one: should it go to the joint holder automatically, or should your Will decide?
4. Check your property too. A home owned as joint tenants passes by survivorship in exactly the same way as a joint account. You can check how your home is held through HM Land Registry.
5. Look at pensions and life insurance. These often pass outside your Will as well, usually guided by an expression of wish form. From 6 April 2027 most unused pension funds will also count towards the estate for Inheritance Tax (see what happens to my pension when I die).
6. Make or update your Will so it covers everything that isn't joint.

Citizens Advice has a helpful overview of dealing with a bank after a death, which is worth reading alongside your list. Our guide to closing bank accounts after a death covers the steps for executors.

Making sure your Will is valid

Once you know what your Will needs to cover, make sure it is properly signed. Under section 9 of the Wills Act 1837, a Will must be in writing, signed by you and either signed or acknowledged in front of two witnesses who are present at the same time. The witnesses then sign too. A witness, or a witness's husband, wife or civil partner, shouldn't benefit under the Will, so choose two independent adults.

What to do next

1. Find out which accounts are joint and which are in your sole name.
2. Decide whether that matches your wishes, especially if you are unmarried, in a second marriage or added to a parent's account.
3. Use a mandate or Lasting Power of Attorney for practical help, rather than a convenience joint account, if you don't intend the money to be a gift.
4. Write down what you intend for any joint account where it might be unclear.
5. Make a Will that covers everything that doesn't pass automatically.

Joint accounts are one of the quiet kindnesses of everyday life: they keep the household running when one person can't. Knowing exactly what they do and what they don't means your Will can take care of the rest.
