A lasting power of attorney allows someone you appoint to help make decisions or make them on your behalf in specified circumstances. In England and Wales there are separate documents for health and welfare and for property and financial affairs.
Start with trust and practicality
Consider whether the person understands your preferences, can keep records and is willing to take on the responsibility. If appointing more than one person, think about how they will work together. Talk to the proposed attorneys before completing the forms.
Understand when powers can be used
The two types of lasting power of attorney have different scopes and conditions. The document must be made and registered through the proper process. It is easier to discuss these choices while you can explain your wishes clearly, particularly where family or financial arrangements are complicated.
