How long does it take to register a power of attorney?

A lasting power of attorney takes 8-10 weeks for the Office of the Public Guardian to register, if there are no mistakes.

But if there are mistakes, they will send the LPA back — and may ask you to pay an additional £41 fee and complete a fresh form all over again.

If the donor has already lost mental capacity, they can’t sign and the LPA can’t be registered. So it’s best to register a power of attorney sooner rather than later.
