Most people who become the conservator of an adult who is not capable of taking care of themselves physically and/or their financial affairs are either close family members (adult child or adult grandchild) or a close friend of the person needing a conservator.A petition is filed in the superior court of the county one lives in asking for the conservatorship of the person where declarations of medical personnel and treating physicians are submitted and some times live testimony.The wishes of the person who would be subject to the conservatorship are also listened to by the court assuming that the person who is the subject of the petition can speak coherently.The court also looks at the qualifications and relationship of the potential conservatee and conservator in making its decision on the issue. You should have an attorney handle all legal work for such a proceeding in that it complicated and if the petition is granted, the conservator has a lot of responsibility.
