Transfer of Property Act: Section 52 Transfer of property pending suit relating thereto: During the pendency in any Court having authority within the limits of India excluding the State of Jammu and Kashmir or established beyond such limits by the Central Government of any suit or proceeding which is not collusive and in which any right to immoveable property is directly and specifically in question, the property cannot be transferred or otherwise dealt with by any party to the suit or proceeding so as to affect the rights of any other party thereto under any decree or order which may be made therein, except under the authority of the Court and on such terms as it may impose.
