Notice period extension

As per your situation let me tell you than an employee can only extend his notice period if he wishes so, otherwise an employer has no right legal right for extension of notice period against the wish of his/her employees.

Yes, you should proceed to file a case in labor courts as you have valid reasons and urgency.

Yes you can proceed with the legal case putting your original letter of appointment as a reference.

Thanks Hasan & Kevin. 

Can this be filed anywhere in India or only valid where the company is located.

Also will it get an answer in one month ? as it is urgent for me 

It depends on the Lawyer you choose and the court proceedings.

Below is the email i received some times back. i have replied telling that i am not agreeing on a two months notice period.  Now they are telling the notification has  been sent already regarding this. Is this applicable even if i disagree ? don't we have right to reject or accept ? please advise 

"In furtherance to the Appointment Letter issued, we would like to inform you that there is an amendment with reference to clause 5.1 that your notice period has been extended for 2 months instead 1 month as per the notification received from the client"
