How is a guardian appointed?
A guardian is appointed in the courts through a process called guardianship. You petition the court for determination of incapacity. When that incapacity is determined, then a guardian is appointed based upon the petitions that are filed. You could have competing guardians being filed, petitions being filed, that say to the court, “I would like to be the guardian,” or another family member would like to be the guardian, and then the court decides which guardian is appointed over you.
