Start with jurisdiction, not a national rule
Ask where the event happened, where the parties are located, and whether more than one state may be connected. Those facts can affect which law and court apply; a directory page cannot decide that question.
Separate the filing period from the accrual date
A statute may describe a number of years, but the legal question also includes when the claim accrued, whether an exception applies, and whether a shorter notice step comes first.
Look for special defendants and claim types
Public entities, medical providers, employers, product manufacturers, minors, and wrongful-death claims can trigger separate procedures or periods.
Verify the lawyer through the regulator
Search the individual lawyer’s record with the state licensing authority. A firm profile and an individual license record answer different questions.
