A Hindu male can claim maintenance from his wife under:

Section 24 of the Hindu Marriage Act, 1955 permits either wife or husband, if lacking sufficient independent income, to seek maintenance pendente lite and litigation expenses in proceedings under that Act. Section 18 of the Hindu Adoptions and Maintenance Act, 1956 protects a Hindu wife, and section 144 of the Bharatiya Nagarik Suraksha Sanhita, 2023 (formerly section 125 CrPC) covers a wife, children and parents, not a husband. Therefore section 24 is the listed route for the husband on the stated financial conditions.
