Is it permissible to register the house in the name of the second wife without informing the first wife and her children, especially since the second wife's children are young and the husband does not own any other properties or money?

Justice must be observed between wives in all possible matters, such as gifts, expenses, and intimacy. If a house is registered in the name of the second wife, a similar one must be registered for the first. However, leaving things as they are is the safest approach, so that nothing is registered in their names. Everyone is advised to be just and to consider kinship, because registering houses in the names of wives or children may lead to future disputes and deprive other heirs.
