Divorce by agreement is undoubtedly the most cost-effective way. It only requires paying some cost and registration. Article 21 of the "Marriage Registration Management Regulations" stipulates that parties involved in registration of marriage or replacement of marriage certificates or divorce certificates must pay a production fee. The charging standards shall be stipulated and announced by the pricing department of the State Council in conjunction with the financial department of the State Council. At present, it seems that there is not much difference in the cost of divorce certificates stipulated by various places, which is about 10 yuan.
