A preliminary decree in a partition suit declares shares but the case remains open until a final decree divides the property. An impleadment petition by a third party claiming rights through a gift deed can be filed while the suit is pending. The court will consider if the gift deed predates the suit and if the third party was unaware of the proceedings. If allowed, the court may reopen the case, hear the new party, and potentially amend the preliminary decree to protect their interests.
