Dear Manav, While mutually agreeing for a notice period of one month, you have also agreed for service rules, regulations and policy of the company as applicable from time to time. It is not very difficult to prove that the applicable company policy at the time of resignation was 90 days notice period. So there is much force in insisting for notice period of three months. In case you fail to serve the notice period, then the company can take action including presumption of abandonment.
To be a valid agreement it requires mutual consent. You are right, but at the same time you have also agreed on a blanket clause providing for applicability of service rules, regulations and policies of the company. So there is an arguable point in favour of enforcement of three month notice period.
