In all cases in which the court deems appropriate, the court shall also appoint a person, other than the person appointed to represent the minor, as guardian ad litem for such minor to speak on behalf of the best interests of the minor, which guardian ad litem is not required to be an attorney-at-law but shall be knowledgeable about the needs and protection of children. The Court of Probate shall appoint counsel to represent any respondent who notifies the court that he or she is unable to obtain counsel, or is unable to pay for counsel. The cost of such counsel shall be paid by the person whom he or she represents, except that if such person is unable to pay for such counsel and files an affidavit with the court demonstrating his or her inability to pay, the reasonable compensation of appointed counsel shall be established by, and paid from funds appropriated to, the Judicial Department, however, if funds have not been included in the budget of the Judicial Department for such purposes, such compensation shall be established by the Probate Court Administrator and paid from the Probate Court Administration Fund. In the case of a minor, such affidavit may be filed by a suitable person having knowledge of the financial status of such minor.
