What Happens to a Joint Bank Account When Someone Dies?

Most joint current and savings accounts in the UK are held on a survivorship basis, meaning that when one holder dies, full ownership passes to the remaining holder or holders without needing to go through the deceased's estate. The surviving holder simply needs to notify the bank and provide a death certificate so that the account records and any cards can be updated to reflect the sole name.

This is different from how a sole account works, where the whole balance is frozen and released only to the personal representatives. With a joint account there is generally no freeze on the surviving holder's ability to use the money, which can be genuinely helpful for meeting immediate household costs after a death, particularly where the account was used for shared bills.

Banks typically ask to see an original or certified copy of the death certificate, and will update the account to remove the deceased's name once this is provided. Some banks may also ask for identification from the surviving holder, particularly if the account had not been used for some time or if there is anything unusual about the request.

It is worth notifying the bank reasonably promptly, both to keep records accurate and because some financial institutions cross-reference death notifications through shared registers, which can otherwise cause confusion if the bank finds out from another source before being told directly.

Passing to the survivor automatically does not mean the money disappears from the deceased's estate for inheritance tax purposes. If the deceased contributed some or all of the funds in the joint account, HM Revenue and Customs can treat their share as part of their estate when working out whether inheritance tax is due, even though the survivor keeps the money outright.

Working out the deceased's share can be straightforward where contributions were clearly split, but it is often less clear cut in long-running joint accounts where money from both holders has been mixed together over many years. This is one of several areas where individual advice is genuinely useful, since the right answer depends heavily on the couple's specific financial history and cannot be assumed from general rules alone.

It can be tempting to think that holding accounts jointly avoids the need for a will altogether, since the money passes straightforwardly to the survivor. This works for the specific balance in that account, but it says nothing about who should inherit everything else, including property, other savings, pensions outside the estate, and personal belongings.

It also does not deal with what happens if both joint holders die close together, or if the surviving holder later wants the money to go to particular people rather than simply forming part of their own estate. A will remains the tool that sets out the full picture of who should benefit from everything you own, in whatever order events actually unfold.

Because joint accounts sit slightly outside the normal probate process, they are easy to overlook when someone is drawing up a list of what they own for estate planning purposes. It is worth keeping a clear, up to date note of which accounts are held jointly, who the other holder is, and roughly how much of the balance came from each person's own money, particularly for older accounts where memories fade.

My Posh Will's guided online will service includes an estate record for exactly this kind of information, so that whoever deals with your affairs later has a clear picture of what exists and how it is held. A single will costs £69 and mirror wills for couples cost £89, both one-off payments with lifetime access, covering England and Wales with clear signing and witnessing instructions included.
