As per Hindu law, who among the following is not entitled to maintenance?

Under section 18(3) of the Hindu Adoptions and Maintenance Act, 1956, a Hindu wife is not entitled to separate residence and maintenance from her husband if she has "ceased to be Hindu" by conversion to another religion. A divorced or judicially separated wife is not disentitled merely for that reason, since she may claim maintenance under section 25 of the Hindu Marriage Act, 1955, so the catch-all is also wrong.
