A father-in-law can gift any amount to his daughter-in-law without immediate tax for her. However, any income generated from the gifted amount will be taxable in the father-in-law's hands due to clubbing provisions. If the father-in-law is deceased, the daughter-in-law cannot receive a gift but can receive assets through inheritance via a will or family settlement, which are fully tax-exempt.
