I don't know the real name of the other party, only know the micro signal, and I can't send a lawyer to it. The lawyer's letter needs to know the name and address of the other party, otherwise it can't be delivered.
A lawyer's letter refers to a professional legal document produced and issued by a lawyer to reveal and evaluate relevant facts or legal issues and then make a request to achieve a certain effect. A lawyer uses a lawyer's letter to make a legal evaluation and risk assessment of a fact, with the purpose of using the legal scale and the lawyer's judgment.
