Start with the category that best matches the incident, then use the related pages for more specific questions. A car crash, for example, may also involve an uninsured driver, a commercial vehicle, or disputed intersection fault. Those details can change which evidence and insurance policies matter.
If you are uncertain where to begin, gather the records you have and contact the firm before signing a release or giving the opposing insurer a recorded statement. An attorney can identify the likely claim, important deadlines, and evidence that should be preserved.
