The process should use criminal-investigation material where helpful without depending on the criminal case to do the civil work.
Collect impairment and crash records
Identify police agencies, toxicology, video, witnesses, vehicle evidence, and any criminal-case materials relevant to the collision.
Establish causation and responsible parties
Show how the driver’s conduct caused the crash and evaluate other parties only when supported by facts and governing law.
Document injuries and losses
Build the medical, wage, future-care, human-loss, and property record independently of the criminal proceeding.
Pursue available civil remedies
Coordinate insurance claims, settlement strategy, any additional damages allowed by law, and litigation when fair resolution is not available.
