There are two types of lasting powers of attorney, property & financial affairs and health & care issues.
Lasting powers of attorney ensures that the donor, if they lose capacity, has a suitable appointed person (attorney) to make decisions for them. This could involve working with Banks, Building Societies, selling property, direct debits etc. It also may mean working out care issues, for example, what sort of care and medical treatment the donor should receive, such as life saving actions.
If you don’t have lasting powers of attorney in place, your spouse, let alone your children, may encounter many issues – bank accounts can be frozen, property can’t be sold, and also local authorities or doctors can and will make decisions on your behalf.
