In most states, an outside party or agency must review the facts of the case and submit a report, usually required to be in writing, to the court before the court makes a decision on the request to establish a conservatorship or guardianship. Usually the outside party is a local County Mental Health representative called an investigator. They are often required to be experts in some appropriate field, such as social work, mental health, a medical field, or law. Procedures for conservatorship of an adult are often different from those for minors.
