Rule 4.2 Communication With Person Represented By Counsel
In representing a client, a lawyer shall not communicate about the subject of the representation with a person the lawyer knows to be represented by another lawyer in the matter, unless the lawyer has the consent of the other lawyer or is authorized to do so by law or a court order.

甲方律師可以和乙方律師聯係，甲方客戶可以和乙方客戶聯係，但是甲/乙方律師不能直接和乙/甲方客戶直接聯係，除非雙方律師同意這樣的聯係。
