Is the husband obligated to pay the expenses for renewing his wife's annual unpaid leave, or should the wife pay them from her savings, especially if the husband is well-off?

It is the husband's right to move his wife to any place where he resides, even if she dislikes it, provided that he is trustworthy with her and that the path and the destination are safe. The husband must provide for his wife reasonably in terms of housing, food, drink, and clothing. As for the costs of maintaining her job, the husband is not obligated to cover them unless he does so voluntarily.
