How to get fast & quick mutual consent divorce in Mumbai ? Could anyone suggest the necessary formalities ?

Ravi has rightly told, just follow. If you are in hurry to marry some one else then go ahead in a cultural way. Dont let your ex know how and when did you get married. Let him wait as long as he wants. Dont waste your money to high profiled Dacoit , I mean lawyer . They are all "Thekedars" as long as your case prolongs he is the one benefited.
