Kindly advise me how to separate out my share of 2 flats from a common property with my brother-in-law. Actually we had a vacant plot sharing 50% each. We gave it to the builder for development; he built total 12 flats and kept 7 flats as his share. We sold a flat which was common. Now from the remaining 4 flats (2 in my share and 2 in his share), my brother in law is demanding 50% in each sale-deal of the flats in my share as a security deposit until he sells out his flats, saying that he'll return when his flats are sold since it's a common property and his sign is required on sale-deed. Although he has signed an agreement made by a notary on Rs. 100 bond paper in front of the witnesses last year. He doesn't seem to sell his share of flats and eyeing 50% on my share. Please help me how to overcome this legally…
