If a loved one lost mental capacity to make decisions for themselves about their finances or welfare and they have not made a Lasting Power of Attorney, you can apply to become a deputy to make those decisions on their behalf. A deputy is appointed by the Court of Protection, the court will decide on your application and if successful, will issue an order setting out what you as a deputy can and cannot do. There are two types of deputyship - A deputy for property and financial affairs can manage your bank account, pay bills and sell your property. A deputyship for personal welfare can make decisions about where you live, who looks after you and about your medical treatment.
