Guardianship is for a person who is incapacitated and cannot make their own decisions and does not have an agent appointed to act on their behalf (usually through a Power of Attorney). The guardian may be a family member, an advocate who assists the Court, or a formal guardianship agency. A guardianship can be "Plenary" or "Limited." A Plenary guardian will be granted the authority to act for an incapacitated person in all situations, financial and medical. A Limited guardian will only have authority to act for an incapacitated person in the circumstances outlined by the court. Depending on the reasons for needing a guardianship, the court may limit the authority to act to financial or medical decisions only. Whoever is the Guardian, they must act in your best interests in managing your financial affairs and/or to make medical decisions you are unable to make.
