If it has nothing to do with you, even the short message of legal advice may not be true. It is ok to check it through understanding. It is unreasonable not to reply directly or to do it directly according to the legal requirements, because it is unknown whether he represents the legal personnel and whether he has the right to contact you.
However, if you receive a paper version of the lawyer's letter, first of all, the lawyer's letter is true and has legal benefits. It is only a way to urge you to repay, and it has not yet reached the point of prosecution.
The way to check whether you are being sued is as follows:
1. Received SMS notification of prosecution, with case number, court session time, name of sued court, cause of prosecution and court session time.
2. Generally speaking, the court clerk in charge of the case will call the defendant to check the receiving address by fixed telephone before mailing the summons. People who sue at the defendant's domicile sometimes call the defendant to get the documents from the court.
3. Call the court, connect to the manual customer service phone of the sued court, report your name and ID number, and find that you have not been sued.
