Title Right

Sir, I have purchased a plot by sale deed in 2006 from A. It got mutated in my name in 2007 and I am continuously paying rent till 2017-18. In 2015, i got LPC (Land Possession Certificate) for the same plot. Recently a person filed a revision appeal in LRDC office claiming the right over the same plot stating that the same plot was sold by A to B in 1980 but was not mutated till now. In 1988 final survey came into force and the plot remain in the name of A. in 2009, B sold entire land to C and party including my plot. C also has not mutated the land. In 2010, C sold my part of plot to D. During this 11 years of my possession, neither B or C nor D objected my possession. D also has not got mutated. while B was selling the land I objected in writing to DM, SDO, Sub Registar, CO, Tehsildar and police to stop registration and protect my land. Now a revision appeal has been filed by D in LRDC court whose first hearing is on 13 Oct 2017. I have sale deed, Photocopy of Mutation, LPC and rent receipt. Request advice.
