Lab for its correctness and genuineness (more particularly Hand writing and Thumb Impression check) - also file a suit for cancellation of Sale Deed cheating made and obtain an order cancellation of Deed directing the Sub-Registrar of Assurances to cancel the deed and also revenue and/or municipal, City Survey or such other authorities to cancel the mutation entires made and to restore the name of actual owner. Also pray for relief of returning the possession of the land in question to the original owners also directing the police authority and under police protection take over the possession. I think this will solve the problem and will restore your ownership possession etc. and under criminal complaints/case the culprit will be punished for all his bad deeds based on the report of Forensic Lab also the persons whosoever has helped knowingly or unknowingly including the wintesses signing the Sale Deed shall be punished for assisting the offence (which may include if any lawyer/notary/gazetted officer or such authoritatives are involved) - also you can pray for compensation for the time the possession held by the other party and cost of all litigations. We have instituted one case before the Additional Principal Judge of District Court (Rural) at Ahmedabad bearing No. 408 of 2008 and same cause and circumstances are there wherein the same thing is cheatingly done for premises instead of land.
