Adult guardianship is a court process that can give another person legal authority to make some decisions for an adult who cannot adequately make or communicate those decisions independently. States use different terminology; financial decision-making authority may be called guardianship of the estate, conservatorship, or another term.
Guardianship can significantly restrict legal rights
Because guardianship can transfer important decision-making authority, courts generally treat it as a serious protective measure rather than a routine convenience. Modern guardianship reform emphasizes person-centered decision making, respect for the individual’s preferences and values, and use of the least restrictive arrangement that can provide necessary protection.
Personal and financial authority may be different
A guardian of the person may be authorized to make decisions concerning matters such as residence, care, and medical treatment. A conservator or guardian of the estate may instead manage money and property. Some states separate these roles; others allow one person to hold both.
How a case generally begins
A guardianship case usually begins with a petition asking a court to determine whether protection is necessary and, if so, what authority should be granted. The adult is generally entitled to notice and an opportunity to participate. States differ substantially on the required evidence, medical evaluations, right to counsel, hearing procedures, standards of proof, and available jury rights.
Less restrictive alternatives
Depending on the situation and state law, alternatives may include powers of attorney, health-care directives, supported decision-making arrangements, representative payees, trusts, limited protective orders, or targeted assistance with particular transactions. The existence of an alternative does not automatically resolve every situation, but it is often important to consider whether a full guardianship is broader than necessary.
Ongoing duties and court oversight
Guardians and conservators are fiduciaries. They may have duties to act loyally, avoid self-dealing, keep records, report to the court, and preserve as much independence as reasonably possible for the protected person. Courts can limit authority, require accountings, and in appropriate circumstances replace a fiduciary.
Interstate issues
When a protected adult moves between states or family members seek competing proceedings in different states, jurisdiction can become complicated. Many states have enacted versions of a uniform law addressing interstate guardianship jurisdiction, transfer, and recognition of orders.
