Hindu law

Admittedly certain changes  and/or modifications are needed considering basic changes in the Hindu Society.

anything earned after marriage thus not come under stridhan 

Stridhan is, generally speaking, what a woman can claim as her own property within a marital household. It may include her jewelry (gifted either by her family), gifts presented to her during the wedding or later, and the dowry articles given by her family.

Gifts given by the parents of the bride are considered “stridhan”, i.e. property of the woman, traditionally representing her share of her parent’s wealth. and in my view salary is not a part of stridhan and it is her wish to share in her household or she can keep with her 

What is your query?, this does not seems to be a query at all, if you so much interested to change the situation, you may initiate the movement.

You have spent the amounts yourself volountarily.  Now you cannot claim. After all  you spent it for your family only and not for third party.

Query of the author itself contains his question i.e.,equality in respect of obligations of male and female in the Indian society.

Yes, on the point of equality of male and female in our society and as our Constitution does not permit and sanction adoption of discriminatory policy monitory contribution of male and female in the family ought to be taken up as equal liability.

If the wife is earning she is liable to contribute to the household expenditure tahat is not streedhan

Sudhish, your thoughts are through provoking however you may note that law comes into being only when dispute arises (especially family law).  Till then it is all as per understanding between family members.  The relationship of wife and husband is not an exception.  Without sorting out issues amicably treating difficulties in relationships are part and parcel of life, if you entertain the thoughts of breakup, you will get to know the provisions of law as punishment.  Punishment because since then your mind will think more about law than about your relationship.  And you will start feeling she is placed on a better footing than me by law and that spoils your relationship further because once law is on her side you will get more ANTI-WIFE.  If you had not thought of break up, you would not have seen law and known law and you would have been happy.
