The Punjab and Haryana High Court has stated that any future maintenance waiver agreement made by a wife in exchange for a lump-sum payment goes against India's public policy, meaning this agreement can't stop a wife from seeking maintenance.
In this case, the wife had received Rs 60,000 as lump-sum for maintenance and signed a compromise agreement waiving her right to ask for any more maintenance. However, since the amount was quite low, she sought additional maintenance from him.
