We (the other 42 persons) have a piece of land measuring 4.2 acres in Visakhapatnam, AP, and would like to enter into an agreement with a real estate agent. The land is under dispute with local authorities. The agent promised to get the land cleared and sold for an appropriate price, for which he is asking for a year to settle all the matters. For this purpose, the agent wants to write an unregistered GPA and MOU. Is one year too long and a valid period? Does any law object to this agreement?
