Under the Hindu Adoptions and Maintenance Act, a wife will not be entitled to maintenance if:

Section 18(3) of the Hindu Adoptions and Maintenance Act provides that a Hindu wife is not entitled to separate residence and maintenance from her husband "if she is unchaste" or ceases to be a Hindu by conversion. Her husband ceasing to be a Hindu is instead a ground under section 18(2) on which she may live separately without losing maintenance, and a disease in the wife is not a statutory bar, so the catch-all option is also wrong.
