If the case is complex and involves a large amount of money, it is recommended to talk to a lawyer. Because lawyers can more accurately grasp the details of the case, formulate appropriate negotiation strategies based on the actual situation, and help the parties reach an understanding agreement. If the case is relatively simple and the amount involved is relatively small, you can negotiate on your own. However, it is necessary to understand relevant legal knowledge to ensure that the content of the negotiation complies with legal regulations and can effectively resolve disputes.
