What is the Islamic legal ruling for dealing with a disobedient wife who mistreats her husband and his family, and how can this problem be solved without resorting to divorce for the third time?

If the wife mistreats her husband and his family and prevents her children from maintaining ties of kinship, then she is oppressive and abusive. She has no right to prevent the children from maintaining ties with your family. She must reside where the husband resides, unless otherwise stipulated.

The husband is not obliged to buy a dwelling for his wife; rather, he is obliged to provide her with a suitable, independent dwelling.

We advise the husband to be patient with her and try to reform her with wisdom, and divorce is the last resort.
