Power of attorney

Power of attorney

A power of attorney allows someone, usually a relative or friend, to make important decisions on your behalf if you’re not able to, or might become unable to in the future.

Which? Legal can help you set up a power of attorney, either temporarily or for the long-term.


The most common reasons for obtaining a power of attorney include:

  • When someone is in hospital or in care and needs day-to-day matters taken care of.

  • When someone has been diagnosed with a health condition such as Alzheimer’s that may cause them to lose mental capacity in the future, and affect their ability to make suitable decisions about their affairs and care.


The ‘donor’ is the person who is appointing someone to make decisions on their behalf.

The ‘attorney’ is the person acting on the applicant’s behalf.


There are two types of power of attorney - one or both may be required in any given case:


General Power of Attorney

This allows someone to take care of financial matters on the behalf of a person who has mental capacity, but is temporarily in hospital care, or has short- or long-term difficulties with communication or mobility which may restrict them

Lasting Power of Attorney

This becomes active once someone has lost their mental capacity. It allows the appointed person  to make financial, health and care decisions on their behalf.

It’s important to note that a power of attorney can only be set up before someone has lost their mental capacity. If they’ve already lost the ability to make decisions, you’ll need to apply through a court order instead.
