Query on Flat purchased from 2 joint owners

I purchased a flat in Mumbai from Mr. Vinod Khanna (Hindu Family) which was co-owned by him and his son Mr. Rahul Khanna. As first owners, they had purchased this flat from the developer in 1998. In the year 2003, Mr. Rahul (son) met with an accident and passed away leaving behind his wife (Priya) and 2 year old son (Raj). Mr. Vinod got an NOC duly signed from all his family members as below. 1. Mrs. Padmavati (Mr Vinod's wife) 2. Mr. Akshay Khanna (2nd son of Mr. Vinod (20 years old) 3. Mrs. Pooja (widow of Mr. Rahul, and mother of Raj - Rahul's son) Post this, Mr. Vinod has got all paperwork done on his name, thereby making himself as the single owner of the flat. Since I have purchased the flat from Mr. Vinod via HDFC Ltd., I have an active home loan. But all paper work including property registration, stamp duty, agreement are under my name. My query is that since Mr. Rahul was also the joint owner, who unfortunately passed away. Can his son (Raj) who was then 2 years old claim for this flat once he is an adult?
