An attorney may withdraw an appearance as attorney for a party if the withdrawal occurs contemporaneously to the written entry of appearance of a new attorney. Otherwise, the withdrawal of appearance shall occur only upon leave of court after notice is given to the party. In all cases where an attorney is withdrawing his or her appearance, including when a contemporaneous entry of appearance is filed by a new attorney or after leave is granted by the court to withdraw as counsel, a written withdrawal of appearance shall be filed with the prothonotary.
