My husband works in the Gulf and has another wife with three children. They haven’t divorced, and she won’t let him see his kids. What can he do to be with his children?

Under Indian law, your husband’s second marriage is void as bigamy is illegal. This means his children are not legally recognized, and he cannot claim parental rights. He should consult a lawyer to explore options for legal recognition of the children and establish a relationship with them, potentially through a court order.
