A Lasting Power of Attorney (LPA) allows your loved ones to take care of you and your finances if you become unable to do so yourself.
There are two types of LPA:
A "Property and Financial Affairs" LPA allows your loved ones to deal with paying your bills, buying and selling your property and managing your bank accounts and investments.
A "Health and Welfare" LPA covers decisions about health and care and even deciding where you are to live. This can only be used if someone is incapable of dealing with such matters themselves, this could be due to Dementia, illness, Disease or caused by an accident.
