If you determine that the endorsed signature on the back of the warrant is not yours then file a Forged Warrant Affidavit form with the County of Sacramento. Please fill out the forged warrant affidavit form, get it notarized and mail the original to County of Sacramento, 700 H Street, Room 3650, Sacramento, CA 95814. The affidavit will be submitted to the bank for processing. It may take the bank eight weeks or more to recover the funds. Once the funds are recovered, the County will reissue another warrant.
