This discussion addresses the legality of a man marrying a second time while his first wife is still alive and living with him. Under Hindu law, such a second marriage is considered void, and the first wife is the only one who can initiate legal action. The second wife has no claim to the husband's property. However, if the husband converts to Islam and marries a Hindu woman, the marriage may be legal if registered under the Special Marriage Act, 1954. No legal action can be taken against the first wife for not disclosing the second marriage.
