The answer to this question is simple—to gather important facts and evidence to bolster your case. The more time that passes after an accident, the more likely that evidence will be lost. In the days that follow an accident, witnesses can recall more accurately the details of the accident. However, as time goes on, memories fade, and details become murky at best.
Hire an accident attorney as soon as possible after the incident, so they can get to work reconstructing the scene, recording witness accounts, and securing evidence to help support your case.
