Is it permissible for a wife to live with her husband's family, including her husband's brother, his wife, and the children of his maternal aunt, if food, drink, and everything else is shared?

The fundamental principle is that the marital home should be independent, with its own facilities, separate from the homes of either spouse's parents, in order to avoid religious prohibitions. However, if the wife waives this right, and there is no fear of temptation (fitna), and she adheres to religious guidelines such as wearing hijab, avoiding seclusion (khalwa), and refraining from forbidden gazes, then there is no objection to living with the husband's family.
