What is the legal definition of an interested person?

You can file on behalf of a vulnerable adult if you are “an interested person.” An interested person is a person who shows the judge that:

  • they are interested in the welfare of the vulnerable adult;
  • they have a good faith belief that the court’s intervention is necessary; and
  • at the time the petition is filed, the vulnerable adult is unable to protect their own interests because of their incapacity, undue influence, or duress.1
