Walnut Creek

For a crash in Walnut Creek, start with the county, not with the most convenient office. The roads around Main Street, Ygnacio Valley Road, and the I-680 corridor sit in Contra Costa County.

When the collision occurred in this county, civil papers usually go to the Contra Costa County Superior Court. Recheck the branch, clerk hours, and phone on that court’s official page. If the wreck actually happened in a different county, file there instead.

The same two-year injury-and-death deadline in section 335.1 applies in this city. Speaking with an insurance company leaves that deadline running. Recheck clerk hours and the courthouse telephone on the official site before a visit.
