Contra Costa County Criminal Defense office in Martinez

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.
