guardian of the person

A guardian of the person is someone who a court appoints to make personal decisions for you if you’re not mentally capable of making them. This includes decisions about where you live, what you eat, getting dressed, washing and having a bath, and staying safe. It also includes decisions about medical treatment and health care.  

Their role is to make the decisions you would make for yourself. If they do not know what you would want, they must decide based on what they believe is best for you.
