The appropriate action an attorney must take to withdraw with client consent is to file a Notice of Withdrawal with Consent. This formal document serves multiple purposes: it notifies the court of the attorney's intention to withdraw, it confirms that the client has consented to this decision, and it ensures that the withdrawal is properly documented in the case file.
Filing the Notice also helps to maintain the integrity of the legal process by providing the court with an official record of the withdrawal, which is especially important in ongoing legal matters. Such documentation can protect both the attorney and the client by clearly indicating that the client is aware of and agrees to the change in representation.
While verbal agreement from the client is essential, it does not provide the same level of formality and clarity that a Notice does. Obtaining a court order for withdrawal is not required when there is client consent, and simply notifying the judge does not fulfill the procedural requirements needed to officially complete the withdrawal. Therefore, filing a Notice of Withdrawal with Consent is the correct and most effective course of action.
