Compensation payable to a guardian must not exceed 5 percent of the income of the ward during any year. In the event of extraordinary services rendered by any guardian, the court may, upon petition and after hearing thereon, authorize additional compensation therefor payable from the estate of the ward. Notice of such petition and hearing must be given to the proper office of the Department of Veterans Affairs in the manner provided in NRS 160.100. No compensation may be allowed on the corpus of an estate received from a preceding guardian. The guardian may be allowed from the estate of the ward of the guardian reasonable premiums paid by him or her to any corporate surety upon his or her bond.
