Is it permissible for the husband's parents to sell or alter the furniture of the marital home and dispose of the wife's personal belongings without her knowledge, even though the apartment is separate and they have the keys?

An independent dwelling, with its necessary privacy and essential facilities, is a right of the wife upon her husband, even if his parents are not pleased. They (the parents) have no right to interfere with the independent marital home by selling it or by any other means that violates this privacy. In return, it is advised to be patient with their harm and to treat them with kindness.
