Acknowledgment and Designation of Arguing Counsel (ADAC) is a process used in many civil and criminal court proceedings in which parties to the case designate a lawyer to argue their case before the court. This process is often used when multiple parties are involved in a case, or when one or more parties have their own lawyer to represent them. The ADAC process involves a designated lawyer providing the court with a written statement that they have been authorized by their client to represent them in the case. This statement must include the name of the lawyer, as well as the lawyer's contact information and the jurisdiction in which the case is being argued. The statement must also include the name of the party the lawyer is representing, and the party's contact information. There are two main types of ADAC: voluntary and mandatory. Voluntary ADAC is used when multiple parties to the case voluntarily agree to designate a single lawyer to argue their case before the court. Mandatory ADAC is used when the court requires one or more parties to designate a lawyer to argue their case before the court. ADAC is an important part of court proceedings since it helps to ensure that all parties to the case are represented properly in court. It also helps to streamline the court process by eliminating the need for multiple lawyers to argue the case before the court.
