The court in which an action is triable may appoint a guardian ad litem at any stage in the action upon its own initiative or upon the motion of: 1. an infant party if he is more than fourteen years of age; or 2. a relative, friend or a guardian, committee of the property, or conservator; or 3. any other party to the action if a motion has not been made under paragraph one or two within ten days after completion of service. (b) Notice of motion. Notice of a motion for appointment of a guardian ad litem for a person shall be served upon the guardian of his property, upon his committee or upon his conservator, or if he has no such guardian, committee, or conservator, upon the person with whom he resides. Notice shall also be served upon the person who would be represented if he is more than fourteen years of age and has not been judicially declared to be incompetent. (c) Consent. No order appointing a guardian ad litem shall be effective until a written consent of the proposed guardian has been submitted to the court together with an affidavit stating facts showing his ability to answer for any damage sustained by his negligence or misconduct.
