A Property and Financial Affairs LPA allows you to appoint someone to manage your financial and property affairs whether or not you have capacity to do so yourself.
On a basic level this could mean paying your bills, collecting state benefits, withdrawing funds from your bank to pay for your shopping.
It could also mean opening or closing bank accounts, moving your money into savings accounts or investing your money.
A property and financial affairs LPA will also allow the attorney to sell your house.
Your attorneys cannot make any decisions about your welfare or health. For this they would need a Health and Welfare LPA.
