QUESTION: Attorney’s firm represents a client in a child custody dispute. Law firm hired a new associate who was employed by the law firm of the opposing party in the custody case. The associate had access to and performed a limited amount of work on the file while employed by the opposing firm. Attorney’s firm erected an “ethical wall,” screening the associate from the custody case. Does Attorney’s firm have a conflict even with the “ethical wall” that has been erected?
ANSWER: As a result of hiring the new associate, Attorney’s firm has a conflict. Although the erection of an ethical wall can help to persuade the former client to waive a conflict, it is not a means of eliminating a conflict under Missouri Rules 4 dash–1.10. Therefore, Attorney’s firm must withdraw from the case unless the opposing party, as the new associate’s former client, consents.
