I do say, there is a big fault in your side. In such investments, you should have placed your close relatives and friends in the key positions.

In this case, if the agreement is signed and approved by the concerned authorities, there is a chance for your rights. But there is a question obviously rises, where were you from August 2011 to Nov.2011?? such a long duration when you are holding a business here??

In this case, you can register multiple complains on life threat, cheating, etc. But, you must be here for the cases and be sure you have enough money to proceed further.

Regarding the signature, i don't think no one can get a signature of a managing director by forcibly. Anyhow, best of luck and the points mentioned on the contract can break easily with the cross points in the same contract. May be it is, the liable person is not having interest in the business or not available for a long duration to continue the business or so... read again carefully and proceed.

If the money reaches someones hand by mistake or by knowingly, its hard to get it back for any reason... keep knocking..
