What must the written procedure for withdrawing or substituting an attorney include?

The correct answer includes the necessity for the written procedure to encompass the client’s contact information, such as their address and phone number. This is vital because it ensures that the client can be easily reached, which is important for continuing communication regarding their case after the attorney’s withdrawal or substitution. By having the client's updated contact details, the court and any involved parties can maintain proper correspondence and ensure that the client is informed about ongoing legal matters.

Additionally, the process of withdrawing or substituting an attorney typically requires consent from the client, and essential information must be maintained for future reference. Knowing the client’s location and means of communication is paramount in legal proceedings, emphasizing the importance of this requirement in the written procedure.
