What is the ruling on agreeing to a second marriage with the consent of the involved parties and the second wife's consent to bear the expenses after the husband experienced financial hardship?

The approval of the husband, the second wife, and her guardian is required for the validity of the second marriage. Its validity does not depend on the approval of the first wife. It is permissible for the second wife to bear all marriage expenses except for the dower, which she may reduce but not completely waive. It is recommended to reduce it due to the blessings it contains and to avoid the harms of exaggeration.
