Section 7. In any sale made under the provisions of this Act, the purchaser may petition the Court of First Instance of the province or place where the property or any part thereof is situated, to give him possession thereof during the redemption period, furnishing bond in an amount equivalent to the use of the property for a period of twelve months, to indemnify the debtor in case it be shown that the sale was made without violating the mortgage or without complying with the requirements of this Act. Such petition shall be made under oath and filed in form of an ex parte motion in the registration or cadastral proceedings if the property is registered, or in special proceedings in the case of property registered under the Mortgage Law or under section one hundred and ninety-four of the Administrative Code, or of any other real property encumbered with a mortgage duly registered in the office of any register of deeds in accordance with any existing law, and in each case the clerk of the court shall, upon the filing of such petition, collect the fees specified in paragraph eleven of section one hundred and fourteen of Act Numbered Four hundred and ninety-six, as amended by Act Numbered Twenty-eight hundred and sixty-six, and the court shall, upon approval of the bond, order that a writ of possession issue, addressed to the sheriff of the province in which the property is situated, who shall execute said order immediately.
