The Alameda County District Attorney’s Office is a statewide leader in victims’ rights and assistance. In the past decade, our pioneering Restitution Unit has obtained over $125 million in restitution orders for both victims of crime in Alameda County and the California Victims Compensation Program who have expended funds on behalf of victims.

Other services

We also offer our community unique victim services such as Criminal Docket Finder, Inmate Locator, and the innovative Alameda County Family Justice Center - a one-stop shop for victims of domestic abuse, sexual assault and human trafficking.
