• Deemed Conveyance of Land having Kul Right over it

I am on the Managing Committee of a Housing Society in Mumbai Sub-urbs. Society is trying for deemed conveyance. It is located on survey no 252 which is divided into 5 hissa numbers. The7/12 (property card) of all the hissa numbers are clear except 252(3) which is not on the name of the builder. The land owner is some person called Mr. Gaikwad. He has not come to claim the land, however there is Qul right of a person called Mr. Patil who claims that he never sold the land to the builder. From what i understand, Qul rights were given to the cultivators. But our society is standing on the land for last 15 years. Can such Qul owner have any claim?
