Define the work you need
Identify the location, event type, possible parties, current stage, and any approaching dates you know about. Ask whether the lawyer handles that kind of matter in the relevant jurisdiction.
Verify and compare
Use the relevant licensing authority to verify current status and public discipline information. A directory entry, advertisement, review, or consultation does not by itself establish fit or quality.
Ask who is responsible
Find out which lawyer would supervise the matter, who would communicate with you, how tasks are delegated, and how the firm handles major decisions.
Read the engagement terms
Review the scope of representation, fee calculation, responsibility for expenses, termination terms, and how a recovery would be accounted for. Keep the signed agreement.
