Answer
You can appoint anyone you trust to be your Power of Attorney as long as they are over 18, able to make decisions and not bankrupt. Usually this means a husband/wife/partner; relative; friend or solicitor. Before you choose someone you should think about whether you trust the person(s) to make decisions in your best interests; whether they would be comfortable taking decisions for you (e.g. about your medical care) and how well they manage their own finances. You can specify people who you would like to be notified before you grant Lasting Power of Attorney if you wish.
