What We Do


The Pierce County Prosecuting Attorney’s Office seeks to be a premier public law office where community safety and public service come first. The dedicated professionals of our Civil, Criminal, and Family Support divisions all play a role in pursuing justice and serving the people of Pierce County

Civil Division

Attorneys in the Civil Division serve as legal counsel for every department of county government. The division stands up for taxpayers in litigation and advises on myriad topics, including public works projects, contracts, public records, and labor issues.

Criminal Division

The office’s largest division pursues justice for crime victims by prosecuting all state felony cases in Pierce County, as well as misdemeanors from unincorporated areas. Deputy prosecutors, with support from legal assistants and victim-witness advocates, pursue wise use of prosecution but also alternatives to incarceration for those motivated to turn their lives around.

Family Support

The Family Support Division works to protect the best interests of children, establish parentage, and enforce child support so financially capable parents pay their fair share. The division represents the Division of Child Support, a DSHS agency, and is state-funded.

Our office is not an investigative agency. To report a crime, please contact your local police department. Copies of police reports can be obtained from South Sound 911.
