Legal analysis: the letter of understanding must first state the specific circumstances of the case, such as the cause of the case. Secondly, state the will of the forgiver. For example, I think his repentance is very good, his confession attitude is sincere, and he has learned his due lessons. I am willing to forgive him. Therefore, I understand Zhang XX's behavior and ask the judicial organs to give Zhang XX a chance to turn over a new leaf and turn over a new leaf according to the principle of "education first, punishment second" and handle it lightly. Finally, the signature place should have the signature of the forgiver and the specific time.

Legal basis: Article 97 of the Civil Procedure Law of People's Republic of China (PRC). If an agreement is reached through mediation, the people's court shall make a conciliation statement. The conciliation statement shall specify the claim, the facts of the case and the result of conciliation. The conciliation statement shall be signed by the judge and the clerk, stamped with the seal of the people's court and served on both parties. The conciliation statement has legal effect after being signed by both parties.
