Walnut

A collision in Walnut is handled as a Los Angeles County civil matter in the Los Angeles Superior Court, often at the civil courthouse the official branch list names for that filing.

Use the official Los Angeles Superior Court locations page to confirm the courthouse, because a Los Angeles County wreck is not a Riverside County filing. If someone was hurt or killed in Walnut, section 335.1 generally gives two years to start the lawsuit.

Shared fault can reduce a recovery, but it does not move the courthouse and it does not freeze the filing window. Ask the responding department for its official crash report, and send an SR-1 when Vehicle Code section 16000 requires it. Confirm the courthouse, the hours, and the telephone on the official page the morning you go.
