There are several non-profit resources available to provide you with free information and guidance in filing a petition for guardianship. Contact the Coalition of Wisconsin Aging Groups, www.cwag.org, or the Aging & Disability Resource Center in Brown County. You can also contact your local office of the Dept. of Health Services, http://dhs.wisconsin.gov
You could also check if there is a legal aid clinic in your county. The clerk of courts office at the courthouse can provide you with the necessary forms or you can find them online at www.wicourts.gov You may also want to consider having an attorney review the completed forms with you before filing at a much lower cost than actual representation.
