Property false claim by uncle. We have original registered docume

Background : My moms mother registered 1.5 acre land as a marriage gift to my mother almost 20 years ago but it was in their possession and paying lease ( no agreement for lease etc). Now her mom under the pressure of my uncle filed a case stating that my mother has sold it back to them some 15 years back ( The land is still registered on my mother’s name and we have original documents) matter is in court but the land is under their possession. Currently: They gave some part of the land for local panchayat to lay road and water pipes for village water supply to make it complicated and to gather villagers support. Can we block that road? Can we make my uncle to pay the yearly lease to court? Can they play around like this even though we have original registration documents? We went to lokayuktha and got the judgement inour favour. Earlier lawyer mislead us. Current lawyer is fine but would like to take second opinion. I am looing for advice and wnt mind to pay for consultation charged
