He has two daughters (unmarried). He is partial and loaned outside ca. 25Lakhs but from us he expects to pay e-bill and even he asks for small amount such as Rs. 100, 500 or 1000 etc. Will distribution: 3 Lands & 2 houses to Uncle 3 Lands & 2 houses to us. 1 Land to himself and 2 houses divided among us due to rent. The Will is stamped from Registrar but status is not locked? I've the Original papers somehow. Today he made the statement that he won't give anything to us until he lives. And everything is under my Uncle's control. What Uncle & GF want to do after Land Pooling: 80% to Uncle 20% to us. 80%: His share, GF share, two daughters share How to solve this peacefully?
