All monies expended and all costs and obligations incurred by the receiver in performing the abatement shall be reviewed by the court for reasonableness and their necessity in performing the abatement. To the extent that the court finds the monies, costs, or obligations to be reasonable and necessary, the court shall issue an order certifying this fact as well as the amount found to be reasonable and necessary. If the costs and obligations incurred due to the abatement have not been paid by an interested party, the order of the court shall be filed with the County Director of Finance within 30 days of its entry by the court and shall thereafter constitute a lien on the property.
