Contra Costa County Criminal Defense office in Martinez

Contact Info

Our flagship office is based in Martinez, the County seat of Contra Costa County. We are located downtown on Main Street, just a few blocks from the courthouses and jail. From this office we serve all Bay Area counties, including Alameda, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma counties.

A criminal case in Contra Costa begins when a prosecutor (District Attorney) files formal charges, a person is arrested, or a grand jury issues an indictment. In all criminal cases, the defendant (person accused of a crime) is presumed to be innocent. That means he or she may not be convicted of a crime unless proved guilty beyond a reasonable doubt. There are several courthouses around Contra Costa where a criminal case may be tried.
