In all cases in which real estate in the County has been decreed to be sold by a court of equity and a trustee has been appointed to make the sale, and in all other cases of trust estates under and by virtue of deeds of trust, last wills or testaments or otherwise, in which proceedings have been commenced in the court of equity for the execution or enforcement of the trust, and where the Director of Finance has no power under the existing law to enforce the payment of taxes, and the taxes on the real estate have been due and in arrears for twelve (12) months, it shall be the duty of the Director of Finance to apply to the Court by petition verified by affidavit, showing the amount of taxes due and in arrear, and the real estate upon which the taxes are due and in arrear. Upon the petition the Court shall pass an order requiring the trustee forthwith to pay the taxes, or show cause to the contrary on or before a certain day to be named in the order, not to exceed thirty (30) days from the filing of the petition. The taxes shall be paid by the trustee out of any rents or other funds derived from or belonging to the trust estates. In case there is no fund belonging to the trust estates liable for the payment of the taxes, the Court shall, upon being satisfied thereof, forthwith pass an order directing the sale of so much of the real estate as may be necessary to pay the taxes and expenses of the sale, in such manner and after such notice as the Court may think proper to direct. The sale shall be reported to the Court for ratification, as all other sales made under decrees of courts of equity. When ratified and the purchase money therefor has been fully paid, the trustee shall convey the property to the purchaser of the real estate so sold, by good and sufficient deed.
