M.R. Civ. P. 89

(a) Withdrawal of Attorneys. An attorney may withdraw from a case in

which the attorney appears as sole counsel for a client, by serving notice of

withdrawal on the client and all other parties and filing the notice, provided

that (1) such notice is accompanied by notice of the appearance of other

counsel, (2) there are no motions pending before the court, and (3) no trial date

has been set. Unless these conditions are met, the attorney may withdraw from

the case only by leave of court. A motion for leave to withdraw shall state the

last known address of the client and shall be served on the client in accordance

with Rule 5. This subdivision shall not apply to a limited appearance filed under

Rule 11(b) unless the attorney seeks to withdraw from the limited appearance

itself.

(b) Visiting Attorneys. Any member in good standing of the bar of any

other state or of the District of Columbia may at the discretion of the court, on

motion by a member of the bar of this state who is actively associated with the

out-of-state attorney in a particular action, be permitted to practice in that

action. The court may at any time for good cause revoke such permission

without hearing. An attorney so permitted to practice in a particular action

shall at all times be associated in such action with a member of the bar of this

state, upon whom all process, notices and other papers shall be served and who

shall sign all papers filed with the court and whose attendance at any

proceeding may be required by the court. Visiting attorneys shall not be

permitted to file limited appearances.
