LPAs and joint bank accounts
Guidance from Estate Advisory Group
Written and legally reviewed by Ramani Gill TEP, Solicitor and private client practitioner·Last reviewed 13 August 2026
The common assumption is that a joint account keeps working. Many banks restrict the account instead, and the other holder's access can be limited overnight.
What banks actually do
Practice varies by provider. Some allow the capable holder to continue operating the account; others restrict it to essential payments, block cards and online access, or freeze it pending authority for the incapable holder's share. You will not know which until it happens.
Why an LPA still matters
- Sole accounts, ISAs and pensions in one name are unreachable without one.
- A jointly owned house cannot be sold without authority for both owners.
- Investments, insurance and tax affairs are almost never joint.
- Care decisions are not a banking matter at all — that needs a health and welfare LPA.
Practical steps for couples
- Both make financial LPAs, appointing each other with an adult child as replacement.
- Register the LPAs with every provider once they come back — see using an LPA with banks.
- Keep some money accessible to each of you individually, so a restriction is not a crisis.
- Check whether any account or policy is in one name only. Most couples find several.
A worked example
Peter and his wife Diane hold a joint current account. When Peter has a stroke and loses capacity to manage money, their bank restricts online access on the account until it sees a certified copy of Diane's registered LPA for Peter, even though the account is joint. Diane had registered LPAs for both of them two years earlier as a precaution, so she supplies the certified copy and full access is restored within a fortnight — see certified copies of an LPA.
Joint accounts versus sole accounts
| Account type | Risk without an LPA |
|---|---|
| Joint current account | May be restricted to essential payments or frozen pending authority |
| Sole savings account or ISA | Completely inaccessible to anyone until a deputy is appointed |
| Joint mortgage or jointly owned house | Cannot be sold without authority for both owners |
| Pension in one name | Frozen; attorney needed to deal with the provider |
What to check with your bank now
- Ask each bank and building society what their policy is on joint accounts and incapacity, before it becomes urgent.
- Register your LPAs with major providers in advance where the bank allows it — see using an LPA with banks.
- Note which accounts, ISAs, premium bonds or investments are sole-name only — these are the ones an LPA protects most.
Common questions
Can I just add my child to my account instead?
It gives them access but also gives them ownership, exposes the money to their creditors and can create tax and benefit problems. An LPA is the cleaner tool.
Does an attorney get access to the joint account?
They act for the donor's interest in it. Banks handle this differently, so ask the provider how they record LPAs over joint accounts.
Do premium bonds count as a joint account?
No, NS&I products including Premium Bonds are always held in a sole name — see LPAs and Premium Bonds and NS&I for how attorneys deal with them.
Will a joint account avoid probate too?
That is a separate point about what happens on death, not incapacity — a joint account usually passes to the survivor automatically, but an LPA only operates while the donor is alive.
