Tennessee ethics rules for attorneys who represent people involved in personal injury cases or wrongful death cases on a contingent fee basis provide that the lawyer must have a written fee agreement with their client.
It is important that, as a prospective client, you read the agreement and make sure you understand what the fee is and how it will be charged.
If you are pressured to sign it the same day you meet with the lawyer, be careful. If you must take it home to read it carefully, or to review it with a family member, you should do so. Do not be forced into signing such an agreement before you have had the opportunity to study it. Do not be afraid to ask questions about any provision of the agreement that you do not understand.
