My wife is not willing for a divorce and wants to stay by herself I dont unite with her...
So it will be contested divorce = not easy (rather the most difficult thing) to obtain.
Is there a way to resolve this amicably? How can I get divorce and not pay alimony?
Try to discuss this issue with her amicably (but seems that she wont agree for divorce).
first of all - if its contested divorce, it will take 5/8/10 ... n number of years.
if u get successful proving her cruelty, thats the easiest (of all other available) way.
