Is a wife entitled to refuse her husband's mother living with them in their small apartment, especially since she stipulated living alone when she got married, and given that his mother interferes a lot, and to avoid the burden of daily cooking for two people in the husband's absence?

Legally, a wife has the right to reside in a separate dwelling, not shared with her husband's family. If she stipulates this at the time of the marriage contract, her right becomes even more affirmed. The wife is not obligated to serve her husband's mother unless she agrees to do so willingly and wholeheartedly. If the husband's mother interferes in the private affairs of the couple, she does not have that right.

It is preferable to handle the matter with wisdom and patience to avoid problems.
