What is the religious ruling on a married man secretly marrying another woman who waives all her rights (lodging, maintenance, inheritance) and is content with meeting him once or twice a week, with the knowledge of the second wife's family but without the knowledge of the first wife? And is this act considered a betrayal of the first wife?
It is permissible for a woman to waive some of her rights, such as maintenance, housing, and equitable division (of nights), for her husband. She has the right to retract this waiver and demand her rights at any time. There is no sin upon the husband for concealing the news of his second marriage from his first wife.
