What does it mean to send a legal letter to your address and work unit after accepting the case, will it?

Legal notification letters are usually sent by cooperative law firms, which means you will be sued. The letter sent by the law firm informs you that you will be sued, and also hopes that you can come up with a reasonable solution so that you can not sue. It depends on what situation you encounter, and contact you to try to deal with the problem through negotiation.
