If the joint committee shall be unable to agree upon a division of the assets or debts of said municipalities, or in case any of the municipalities desires to have such allotment and division made by commissioners, the governing body of any of the municipalities may apply to a judge of the Superior Court for the appointment of three disinterested persons as commissioners, who shall make the above appraisal and apportionment in the manner hereinbefore provided; and their determination in writing, signed by any two of them, shall be binding and conclusive upon each of the municipalities. The commissioners shall receive such compensation for their services as the judge shall by order determine, to be paid by the municipalities equally.
