Divorce by agreement is valid as long as it is written as follows:: 1. Personal information of both men and women, including name, gender, nationality and ID number; 2. Both men and women divorce voluntarily, without any coercion or fraud; 3. If the child is underage, both parties must reach an agreement on the custody and maintenance of the child; 4, both husband and wife must also deal with husband and wife * * * with debt and * * * with money. First of all, the parties who signed the divorce agreement personally brought their ID cards and materials to prove that the two sides reached a divorce agreement, and voluntarily went to the local notary office to sign the divorce agreement and apply for notarization. After examining the authenticity and legality of the contents to be notarized, the notary office decides whether to notarize them. Both parties to the divorce agreement go to the notary office to notarize the divorce agreement, hoping that both parties can fulfill the contents recorded in the divorce agreement as promised. The notarization of the divorce agreement is the public proof of the agreement between the two parties. The authenticity and legality of the notarized divorce agreement have been recognized by law. Simply put, a notarized divorce agreement is more effective than a notarized divorce agreement. When there are several inconsistent divorce agreements, the notarized divorce agreement has higher legal effect and is superior to other divorce agreements. Once one party fails to perform the agreement in accordance with the contents of the divorce agreement, resulting in the infringement of the legitimate rights and interests of the other party, the injured party can bring a lawsuit to the court and issue a notarized divorce agreement, and the court can quickly confirm that the relevant provisions in the divorce agreement can be enforced.

According to Article 1076 of the Civil Code of People's Republic of China (PRC), if a husband and wife divorce voluntarily, they should sign a written divorce agreement and apply for divorce registration in person at the marriage registration office. The divorce agreement shall specify the expression of the will of both parties to divorce voluntarily and the consensus on matters such as child support, property and debt disposal.

Article 69 of the Supreme People's Court's Interpretation on the Application of Marriage and Family in the Civil Code of People's Republic of China (PRC). If the divorce fails in the divorce proceedings and one party goes back on his word, the people's court shall consider that the property and debt settlement agreement has not come into effect, and make a judgment according to the actual situation and the provisions of Articles 1087th and 1089th of the Civil Code. The provisions on property and debt disposal in the divorce agreement signed by both parties according to Article 1076 of the Civil Code are legally binding on both men and women. After the divorce registration, the people's court shall accept the lawsuit brought by the dispute arising from the performance of the above agreement.
