What is the difference between a lawyer's letter and a lawsuit?

Legal analysis: the purpose of sending a lawyer's letter is to block the prescription, urge and warn the other party. There is a high probability that a lawyer will intervene and take the judicial route to urge the other party to face up to it; If the above objectives are not achieved, prosecution will be initiated. Lawyer's letter, also known as lawyer's letter, refers to a professional legal document made and issued by a lawyer in order to disclose and evaluate relevant facts or legal issues and then make a request to achieve a certain effect. The indictment is applicable to criminal proceedings. It is a legal document for national judicial organs (people's procuratorates) to initiate public prosecution and criminal proceedings. The parties in the indictment are the prosecutor and the defendant. The indictment applies to civil and administrative proceedings.

Legal basis: Article 565 of the Civil Code of People's Republic of China (PRC). If one party claims to terminate the contract according to law, it shall notify the other party. When the notice reaches the other party, the contract is terminated; If the notice states that the debtor fails to perform the debt within a certain period of time, the contract will be automatically terminated. If the debtor fails to perform the debt within the time limit, the contract will be terminated at the expiration of the time limit specified in the notice. If the other party disagrees with the termination of the contract, it may request a people's court or an arbitration institution to confirm the validity of the termination of the contract. If one party brings a lawsuit or applies for arbitration to claim to terminate the contract without notifying the other party, and the people's court or arbitration institution confirms this claim, the contract shall be terminated when a copy of the complaint or arbitration application is served on the other party.
