You are trying to find savings accounts nobody in the family has any paperwork for, and it feels like looking for something that might not be there. The reassuring part is that a live bank account is very hard to hide from the people sorting out an estate, because money moving in and out of it leaves marks on every other account it touches. You do not need a magic list, and you do not need to find any paperwork first. You need two things: a free search of the accounts firms have lost track of, and a patient read of a year's worth of statements.
So the practical answer to how do I find out if someone had a bank account we didn't know about is to combine those two methods. The free search catches dormant and forgotten accounts held by firms that take part in it. The statement audit catches everything still active, because an account you do not know about almost always shows itself through a standing order, a transfer, or a single line of interest paid once a year.
This page sets out both, in the order that finds accounts fastest, and it explains what to do once you have found one. It also explains why a dormant balance is never simply lost, even when it has sat untouched for many years.
At a glance
- No single search finds every account. Pair the free dormant-account search with a statement-by-statement audit.
- An active account you do not know about usually shows up as interest, a standing order, or a transfer on an account you do have.
- Read a full twelve months of statements, because annual interest and yearly payments appear only once.
- Dormant money is not forfeited. It can be reclaimed by the estate with proof of entitlement, and there is no deadline.
- Above a bank's own release limit you will need a grant of probate, or confirmation if the death was in Scotland.
The two tools that actually work
There is no one place that lists every account a person held. Anyone who tells you otherwise is guessing. What exists instead are two reliable tools that, used together, cover almost all of the ground.
The first is the free mylostaccount service, run by the banking and building society trade bodies together with National Savings and Investments. It searches the records of the banks, building societies and NS&I that take part, and it costs nothing. The second is an audit of the paperwork and statements you already have, done properly. Neither is complete on its own. The search misses firms that do not take part and products it does not cover; the audit misses an account that has had no activity for a long time. Run both and the gaps in one are filled by the other.
Start the audit first, because it usually produces results within an afternoon, and start the search in parallel because it can take a little while to come back. Everything below is how to get the most out of each.
Read a full year of statements, line by line
This is the method that finds active accounts, and it is more powerful than people expect. Gather a full twelve months of statements for every account you already know about, then read every line and write down anything that points to a provider you have not accounted for.
Specific things give an account away. Interest credited from a savings provider tells you there is a savings balance somewhere earning it. A standing order or transfer to a name you do not recognise points to another account in that person's own name. An ISA subscription, often made in March or April around the end of the tax year, points to a stocks and shares or cash ISA. Dividend payments point to shareholdings and the account they are paid into. Even a small regular payment to a provider can be the thread that unravels a whole account you did not know existed.
It helps to know what each kind of entry is telling you, so you are reading with a purpose rather than hoping something jumps out.
| What you see on the statement | What it usually means |
|---|---|
| Interest credited from a provider | A savings or deposit account somewhere is earning it |
| Standing order or transfer to an unfamiliar name | Another account in the person's own name, or a regular commitment |
| A payment in March or April to an investment firm | A cash or stocks and shares ISA subscribed before the tax year end |
| Dividend payments arriving once or twice a year | Shareholdings, and the account those dividends are paid into |
| A small regular payment to a named company | A subscription, an insurance premium, or a lender to follow up |
A full year matters because timing hides things. Annual interest is paid once. A yearly premium leaves once. A dividend might arrive twice. Look only at recent months and you will walk straight past them. Note every counterparty you cannot immediately explain, then work through the list one by one and contact each firm. It is slow, methodical work, but it is the part that finds the accounts a search will never reach.
The free dormant-account search
For accounts that have gone quiet, the statement trail runs out, because a dormant account by definition is not moving money anywhere. This is where the free search earns its place. The mylostaccount service checks participating banks, building societies and NS&I in one go, using the person's name, dates and former addresses.
NS&I products such as Premium Bonds and savings certificates are worth a specific mention, because they are commonly held, easily forgotten, and often paper-based with nothing arriving to remind anyone they exist. NS&I can be searched as part of the same process. The government's own guidance on how to find lost bank and building society accounts explains the route and confirms it is free, so you never need to pay a tracing firm for something you can do yourself.
Have the details ready before you start: the full name of the person who died, their dates of birth and death, and the addresses they lived at, because old accounts are often registered to an address the family has long since left.
What "dormant" means, and why the money is not lost
Families often fear that an account left untouched for years has been closed and the money gone. It has not. A dormant balance in the UK is not forfeited, however long it has sat there.
Where a bank or building society has moved an unused balance into the industry's dormant assets scheme, the money is transferred to a central fund but the customer's claim on it survives in full. The estate can reclaim it with proof of entitlement, and there is no time limit for doing so. In other words, the account being called dormant changes where the money is held, not whether the family can get it back. The mylostaccount search covers the firms that take part in the scheme, which is why it remains the right first step for old balances.
The clues that are not in the statements
Some accounts leave no trace on paper at all, and for those you look around the person's life rather than their statements. The post is the obvious place: a single annual statement or a marketing letter from a provider is often the only sign an account exists, so keep every envelope that arrives for months after the death rather than binning it.
App-only banks are a growing blind spot, because there is no branch, no passbook and frequently nothing posted at all. A banking app on the phone, a debit card in the wallet you do not recognise, or a payment confirmation by text or email can be the only clue. Much of this now lives in the person's email inbox, which makes access to their digital accounts genuinely useful; our guide to what Google hands over to the family of someone who has died explains how that access actually works and what it will and will not give you.
Keys and safe deposit boxes deserve a specific look. A small unlabelled key, a receipt from a storage or vault provider, or a rental charge on a statement can point to a safe deposit box holding documents, certificates or valuables that name accounts nobody has found. It is also worth registering the death with the credit reference agencies: it helps close off the risk of fraud in the person's name, and the credit file itself can list lenders and accounts the family had no idea existed.
While you are searching the house you will turn up other things that are easy to misjudge, from pre-paid cards to store credit. It is worth knowing which of them still have value, which we cover in whether gift cards and vouchers are still valid after someone dies, and in the practical business of clearing the house before probate without losing records you will need later.
Turning a found account into money the estate can use
Finding the account is only half the job; releasing it is the other half. Once you contact a provider, it will want the death certificate, proof of your authority to act, and identification. What happens next depends on the balance.
Most banks and building societies will release a modest balance to the personal representative on the paperwork alone, up to a threshold they set themselves. There is no legal figure that applies across the industry, and limits vary widely between firms, so you have to ask each one. Above its limit, a provider will hold the money until it sees a grant of probate. In Scotland the equivalent authority is confirmation rather than a grant of probate, and in Northern Ireland the grant process has its own forms, so the document the bank asks for depends on where the death was registered. Each provider applies its threshold to the balance it holds, not to the estate as a whole, which is why several separate accounts can sometimes be released without any grant at all.
The same audit finds debts, and cover, too
The year of statements you are reading to find savings does double duty. The same recurring payments that reveal an account can reveal a debt, a subscription still charging, or an insurance premium. It is worth capturing all of it in one pass rather than going back through the statements three times.
Regular payments to lenders and credit providers are the start of the separate job of working out what is owed, which we set out in how to find every debt someone left behind. A premium going to an insurer may be a life policy the family did not know about, and tracing that is worth doing carefully; our guide on how to find out if someone has life insurance in the UK covers it, alongside the wider bereavement admin, assets and contracts guide.
Doing this once, for someone else, is also the moment many people realise how hard their own affairs would be to piece together. If part of what you are protecting is that your family should never have to run this search, you can get life insurance quotes and have an FCA-authorised broker price cover against your own circumstances.
Frequently asked questions
Is there one search that finds every account?
No. The free mylostaccount service covers the banks, building societies and NS&I that take part, and it is the right first step, but it will not find every provider or every product. Pair it with a statement audit, because a live account is usually visible in the transactions on an account you already hold, even when there is no paperwork for it anywhere in the house.
What do I look for in the statements?
Interest credits, transfers to a name you do not recognise, standing orders, ISA subscriptions around April, dividend payments and any small regular payment to a provider. A full twelve months matters, because annual interest and yearly premiums appear only once. Note every counterparty you cannot explain and work through the list, contacting each firm with the death certificate and proof of your authority.
What about accounts that have gone dormant?
Dormant balances are not lost. Where a bank has moved an unused balance into the dormant assets scheme, the money can still be reclaimed by the estate with proof of entitlement, and there is no time limit on doing so. The mylostaccount search covers participating firms free of charge, so a long-forgotten account is usually traceable even when nothing about it has arrived in the post for years.
