Within 30 days after receiving full payment for the interest of his ward in any land or realty so sold, such sale having been confirmed under the provisions of this article, the guardian of such ward must report such payment under oath to the court and apply for an order to make a proper conveyance of such interest to the purchaser. The court must examine such report and may also examine witnesses in relation thereto; if, upon such examination, it is satisfied that such payment has been made, it must make an order for such conveyance to be made by said guardian or by some other person, appointed by the court conveying all right, title, and interest of such ward in such land or realty at the time of such sale thereof.
