Is the marital increase in a retired man's salary the property of his wife, and must it be given to her upon her request, knowing that it is calculated to cover the expenses of the increase due to the wife?

Some financial increases in salaries, such as an increase for the married person or one who has children, are the exclusive property of the salary recipient (the husband). The wife or children have no right to it, because it is given to the husband as an aid to him with the burdens of marriage and family, and it is not a gift to individuals. The wife has the right to maintenance and housing according to what is customary.
