Relatives fraudulently sold father's land after his death

Dear Sir, I have a property, and after death of my father, my far relatives, took advantage of it, they have sold their property to a village peasant, which actually belongs to them. But the problem is, the seller has shown my land as his property and made him occupied my property. We were in such understanding till then that, the property is left vacant, as no one in our family is doing cultivation, after my father’s death,(we came to city for educational purpose). Later, we wanted to sell the property and came to know the fact that, my far relatives has sold their property and shown my property as that sold property. Now, we have told the buyer, to leave my land and occupy what he actually bought. We have obtained Injection order from court as well, but we don't have enough capability to tackle them, since, i am finding them intimidating and the property is in village (I can’t go every-time to look after that from Hyderabad). Please guide me what do I have to do? Myi
