In the event of extraordinary services by any guardian, the court, upon petition and hearing thereon, may authorize reasonable additional compensation therefor. A copy of the petition and notice of hearing thereon shall be given the proper office of the Veterans Administration in the manner provided in the case of hearing on a guardian's account or other pleading. No commission or compensation shall be allowed on the moneys or other assets received from a prior guardian nor upon the amount received from liquidation of loans or other investments.
