Individual Buying Property From Andhra Pradesh Educational Society

The private school in my village in the state of AP has decided to sell their land and building due to some financial hardships. I am an individual and I decided to buy the land and building from them. The school is registered under the Society (Andhra Pradesh Societies) and the land/building is registered under the name of "Secretary/Correspondent ABC Educational Society" as per encumbrance certificate (EC). All the members of the society unanimously agreed to sell the school land/building in the general meeting. Also, society is willing to run the school for the next few years so they requested me to rent it after the purchase and I agreed to it. 1. Does any permission needed from Education Dept. or Income tax Dept. or Court to register this property under my name. 2. Do I have to create any trust to purchase this land/building from Society OR Can I directly buy and register it on my name? 3. How can avoid any future legal litigations?
