Are the children of husband and wife who are too old to take care of themselves obliged to support them?

Children have the obligation to support and are not destroyed by marriage. Law on the Protection of the Rights and Interests of the Elderly Article 21 The freedom of marriage of the elderly is protected by law. Children or other relatives shall not interfere with the divorce, remarriage and married life of the elderly. The maintenance obligation of the supporter is not eliminated by the change of the marital relationship of the elderly.
