Notarization is what people call public testimony. It refers to an activity in which the national notary office confirms the authenticity and legality of legal acts and legally significant documents and facts based on the application of the parties and in accordance with legal procedures. Notary agencies are institutions set up by the state to perform national notarization functions. Our country's notary agencies are city and county notary offices, as well as diplomatic representative agencies, namely embassies and consulates stationed abroad. The Notary Office is under the leadership of the judicial administrative agency; but it is not a national judicial administrative agency, but a national notary agency. There is no affiliation between the various notary offices, and the notarial certificates issued by each have the same validity. The notary office is composed of notaries and assistant notaries. Directors and deputy directors may be established as needed. However, the director and deputy director must be notaries and must perform the duties of notaries. All notarized documents must be issued in the name of a notary. Assistant notaries assist notaries in notarization matters. Through notarization activities, the notary office protects public property, protects citizens’ identity and property rights and legitimate rights and interests, safeguards the socialist legal system, educates citizens to abide by the law, prevents disputes, and reduces litigation. Notary agencies handle foreign-related notarizations, protect the legitimate interests of Chinese citizens and overseas Chinese abroad, and safeguard the rights and interests of the country and legal persons in international exchanges; at the same time, they also protect the legitimate rights and interests of foreign citizens and legal persons in my country. According to Article 4 of the "Interim Regulations on Notarization of the People's Republic of China", the business of the notary office is as follows: ⑴ Prove contracts (deeds), entrustments, and wills; ⑵ Prove inheritance rights; ⑶ Prove property donation and division; ⑷ Prove adoption relationships ; ⑸ Prove kinship; ⑹ Prove identity, education, and experience; ⑺ Prove birth, marital status, survival, and death; ⑻ Prove that the signatures and seals on the documents are authentic; ⑼ Prove that the copies, abridgements, translations, and photocopies of the documents are consistent with the originals ; ⑽ If there is no doubt about the document for recovery of debts or items, the document shall be certified to be enforceable; ⑾ Preserve evidence; ⑿ Keep wills or other documents; ⒀ Draft documents applying for notarization on behalf of the parties concerned; ⒁ According to The parties’ applications and international practices, and other notarization matters.
