Do not remain under the impression that wife is earning so you need not pay maintenance on the basis iof earlier some HIGH COURT judgments.
The Supreme Court in the case of Bhuwan Mohan Singh Vs. Meena,reported in 2014
as quoted in
IN THE HIGH COURT OF GUJARAT AT AHMEDABAD
CRIMINAL MISC.APPLICATION (FOR STAY) NO. 18957 of 2015
It shall be open for both the parties to put forward all contentions available in law, except the contention that the wife is earning.
Learn to win the war not battles
. Put all your efforts to see that no maintenance is paid which is possible if you fight a long war on legal mat . It will be worth instead of paying life long liability and she is living like a parasite on your doles. And with this liability you will not attract any worth while partner to live with you.
