Civil Suit Partition - Family Dispute

Hi, we have two floors on property. My uncle/family was staying on ground floor. We are living on first floor. The second floor was built to meet family requirements for additional rooms by my father, but there are no legal papers for second floor. My uncle/family took possession of two rooms on second floor for his sons marriage but never returned to my father and took possession of rooms by fighting with my father. It's been few years now they have possession of them. My uncle filed a civil suit against my father in 2019. The suit is in pending status. During suit dates it was ordered by court that the ownership of groud floor is with uncle and first floor to my father as per WILL. The court narrowed the decision that dispute is of second floor only now as no mention in WILL. Now main question is my uncle most probably have sold the ground floor as we see new owners, also it seems the two rooms on second floor might have also been sold. Is this legal ? The court suit is still ON.
