The defendant in such action shall, within forty-eight hours after such judgment or during the term of the court in which it shall be rendered, file in the office of the clerk of the court in which such judgment was rendered a complaint against the plaintiff for so much money as the lands and tenements are so made better. The filing of such complaint shall be sufficient notice to the defendant in such complaint to appear and defend against it. All subsequent proceedings shall be had in accordance with the practice prescribed in this Code for actions generally.
