“My husband has deserted me”
then you say
I returned at my parents house.
so then he is not deserted you, you deserted him. if there is any mental cruelty, you have to prove there it self in front of his/your parents and elders and meet a amicable solution.
When you involve in legal battle, you lose your valuable time/life and money. for few hundred rupees of maintenance. and if you are educated/capable you will not get that also.
