Compensation payable to curators shall not exceed five percent (5%) of the income of the pensioner during any year, or one percent (1%) of the corpus of the estate, whichever is greater. In the event of extraordinary services rendered by such curator the court may, upon petition and after hearing thereon, authorize additional compensation therefor payable from the estate of the pensioner. Notice of such petition and hearing shall be given the proper office of the bureau in the manner provided in Kan. Stat. Ann. § 73-509. No compensation shall be allowed on the corpus of an estate received from a preceding curator. The curator may be allowed from the estate of his pensioner reasonable premiums paid by him to any corporate surety upon his bond.
