Overview
A lasting power of attorney (LPA) is a legal document that lets you (the ‘donor’) appoint one or more people (known as ‘attorneys’) to help you make decisions or to make decisions on your behalf.
This gives you more control over what happens to you if you have an accident or an illness and cannot make your own decisions (you ‘lack mental capacity’).
You must be 18 or over and have mental capacity (the ability to make your own decisions) when you make your LPA.
You do not need to live in the UK or be a British citizen.
There are 2 types of LPA:
health and welfare
property and financial affairs
You can choose to make one type or both.
Make a lasting power of attorney
You can make a lasting power of attorney (LPA) online or using paper forms.
Either way, you need to get other people to sign the forms, including the attorneys and witnesses.
You can get someone else to use the online service or fill in the paper forms for you, for example a family member, friend or solicitor.
You must register your LPA or your attorney will not be able to make decisions for you.

Signing the forms
You need to sign the forms before you send them off. They also need to be signed by:
the attorneys
witnesses
a ‘certificate provider’, who confirms you’re making the LPA by choice and you understand what you’re doing
Who can be a witness or certificate provider
Witnesses and certificate providers must be 18 or over.
Attorneys can witness each other sign, but they cannot:
witness you sign
sign as the certificate provider
You cannot be a witness if you’re the person appointing an attorney.
