Tom Mason of Zuckerman Spaeder discusses when a lawyer must withdraw from a representation and when a lawyer may withdraw from a representation under the ABA Model Rules (e.g., ABA Model Rules 1.16, 1.2, 1.8, 3.3) and various state Rules. Topics include: • how the ethics rules interact with court rules regarding the entry of a lawyer’s appearance and the withdrawal of that appearance; • the steps a lawyer must or should take with respect to files, client property and client funds after withdrawal; and • the steps a lawyer must or should take with respect to cooperation with successor counsel.
