In a partition suit, the trial court granted partition and passed a preliminary decree (12 years back). One of the parties filed a first appeal in the High Court of Andhra Pradesh. The High Court modified the preliminary decree (2 years back). Final decree proceedings are about to begin in the trial court. Can a party now file a petition in the trial court to further modify the preliminary decree? Is there any period of limitation to file the petition? What kind of petition may be filed? Under what section and order of CPC? Thank you. Surya, Vijayawada, Andhra Pradesh.
