If you don't want to file a lawsuit, negotiate with the other party about how to solve it after receiving the lawyer's letter. If you think you have no problem and are not afraid of being sued by the other party, you don't need to deal with the lawyer's letter. The lawyer's letter itself will not have legal consequences, it is just a warning. The lawyer's letter is generally regarded as a threat of litigation, which may be that the party exerts pressure on the other party in order to gain negotiation advantages, forcing the other party to take the initiative to seek peace; It may also be the litigation warning issued by the parties who lose confidence in conflict resolution. Of course, it may also include the purpose of the parties or lawyers to spy on the other party's truth and temptation. The receipt of a lawyer's letter does not mean that you will bear the risks described in the lawyer's letter, nor does it rule out the possibility that the parties may make up their minds, let alone not have their own courts arbitrate! Therefore, there is no need to scramble and act rashly because of the lawyer's letter. You can keep silent and track the progress of the situation, or you can hire a lawyer to discuss countermeasures, or send a tit for tat lawyer letter to the other party in turn. Of course, the lawyer's letter can also convey the party's declaration of intention or notice of intention, such as urging, refusing, rescission, etc. These will have certain legal consequences, which you may need to carefully evaluate.
