A power of attorney is a legal document that allows someone to make decisions for you, or act on your behalf, if you are no longer able to or if you no longer want to make your own decisions.
There are a number of reasons why you might need someone to make decisions for you or act on your behalf. This could just be a temporary situation: for example, if you're in hospital and need help with everyday tasks such as paying bills.
You may need to make longer-term plans if, for example, you have been diagnosed with dementia and you may lose the mental capacity to make your own decisions in the future.
If any of the situations above happen, and you do not have a Lasting power of Attorney, it will be difficult for your family to access your money and make health decisions for you.
