You can find court forms on the Rhode Island Judiciary website. Depending on your relationship to the abuser, you may need to file in district court or in family court - the forms are listed separately for each court. If you are not sure in which court to file, go to Who is eligible? Do I file in family court or district court? for more information.
You can also go to the courthouse to ask the clerk for the forms. Click on RI Courthouse Locations to find the courthouse in your area. A local domestic violence organization may be able to provide you with the necessary forms as well. To find help in your area, go to RI Advocates and Shelters.
