What is the ruling regarding the conduct of a wife who feels uneasy about her husband's parents living with them in the same house, and consequently restricts her husband's interactions with his parents, fearing the mother-in-law's influence on their marital relationship, especially since the mother-in-law has a history of causing the divorce of her other son?

Legally, it is the wife's right to reside in a private dwelling that no one shares with her except with her consent, even if they are the husband's parents, due to the restriction of her freedom and loss of privacy that this entails. We advise her to be patient in serving her husband's parents to endear herself to him, as there is a reward in it, while striving to win his mother's heart by being kind to her. We do not advise obliging the husband not to interact with his parents unless she is present. Rather, it is possible to reach an understanding with him on how to manage the matter well and give everyone their due. If the situation does not improve and it is highly probable that its continuation will lead to the collapse of the household, then there is no blame on her for demanding her right to an independent dwelling, and the provision for the husband's parents becomes the responsibility of their children.
