Please advise me experts (forged rent deed in court)

First obtain certified copy of such rent deed from Court.  Then file complaint in Police station of jurisdictional court, as the rent deed was submitted in Court.  You have to file case against the given of the receipt also, but you should be ina position to provide that it is fake.  According to me the rent deed may be correct and signatures may be correct, but the contents may not be true.  SO first investigate into the facts as to whether signature is genuine or not.

THE RENT DEED IS A FORGED ONE BECAUSE IT IS WRITTEN ON A WHITE PAPER AND A REVENUE STAMP HAS BEEN AFFIXED AND MY WIFE'S SINGNATURE ONLY THERE.........

Because it is on white paper it can not become a forged one.  If some one signs as another person then only one can call it as forgery and for that the other person's signature must be on record and it has to be confirmed by experts.

First get certified copy from court through your advocate.  Collect signatures of real owner. Let your advocate during arguments object it for taking on record and let that document not be admitted on such valid grounds.
