Under the Hindu Adoptions and Maintenance Act, 1956, a wife is not entitled to maintenance if she:

Section 18(3): "A Hindu wife shall not be entitled to separate residence and maintenance from her husband if she is unchaste or ceases to be a Hindu by conversion to another religion." Living apart on a ground in section 18(2), suing him or earning her own income does not defeat the claim, though her income bears on the amount under section 23.
