Can I file a FIR against fake rent receipts and forge agreement which my tenants produced in court?

I filed a suit of Bonafide in the court of ARC after the death of my tenant on his legal heirs. But they replied to the court that they are not tenants, in fact they are the co-owner of the half property, by virtue of the oral will which their late mother did to them and earlier in the year 1979 the brother of the previous owner did orally will to their mother. Also they enclosed photocopy of some fake rent reciepts issued to other tenants in the property on their mother's name. And they also enclosed a photocopy of forge agreement on ₹2 stamp paper of year 1992, which is not even stamped properly, which says their late mother and me had a pact to receive rent in equal share from other tenants. They say that they don't have original copy of these doc's, but it has to be considered by the court. I want to ask that can I file a FIR against these forged docs?? Whereas I have the registered sale deed in which it is mentioned that there late father is a tenant in the property and moreover their father n mother both had been paying rent to me in their lifetime. I have original rent receipts with their sign. But after the death of their parents I dint issued rent receipts to their legal heirs.
