Timing shapes what is still possible in the days and weeks after a loss. Vehicles get repaired or scrapped, surveillance footage from nearby businesses gets overwritten, and witnesses who saw the moments leading up to the crash become harder to locate as time passes. A prompt, thorough investigation preserves options that can close permanently within weeks of a fatal collision, well before most families are prepared to think about litigation while still grieving. California generally allows two years from the date of death to file a wrongful death lawsuit, but if a government entity's road design or maintenance played any role, a formal government claim must typically be filed within six months, a deadline that arrives quickly. Speaking with an experienced wrongful death attorney early, even before deciding whether to pursue a claim, costs nothing and can prevent an irreversible loss of evidence or rights.
