If the interest of a ward in any parcel of real estate does not exceed $2,500 in value and a private sale thereof can be made for cash, the interest may be sold as provided in this Section instead of as prescribed elsewhere in this Act. The representative of the estate of the ward may file a petition setting forth: (a) the description of the real estate, the interest of the ward therein and the value of the interest sought to be sold; (b) the name and post office address of the ward; (c) a private sale of the ward’s interest can be made for cash; and (d) it is for the best interests of the ward that his interest in the real estate be sold. Upon the filing of the petition the court shall set it for hearing not less than 20 days thereafter. Not less than 15 days before the date of hearing of the petition, the clerk of the court shall mail a notice of the time and place of the hearing to the ward. No guardian ad litem need be appointed for the ward unless the court finds it necessary for the ward’s protection. If on the hearing the court finds that the ward’s interest in the real estate to be sold does not exceed $2,500 in value, a private sale of the ward’s interest can be made for cash and it is for the best interests of the ward that the sale be made, the court shall direct the petitioner to sell the ward’s interest at private sale for cash for such price as the court determines and upon receipt of the purchase price to execute and deliver a deed to the purchaser. The court shall require the representative to furnish a bond conditioned upon his disposing of the proceeds of sale in the manner required by law, and with or without sureties and in such amount as the court directs; and it is the duty of the representative to file the bond in and have it approved by the court.
