Individuals cannot notarize premarital property. According to the Marriage Law: Article 19
 The husband and wife may agree that the property acquired during the marriage relationship and the premarital property shall belong to their own ownership, joint ownership, or part of their own ownership, part of their joint ownership. The agreement shall be in writing. In the absence of an agreement or unclear agreement, the provisions of Articles 17 and 18 of this Law shall apply. The agreement between husband and wife on the property acquired during the period of marriage and the property before marriage shall be binding on both parties. If the husband and wife agree that the property acquired during the marriage relationship shall belong to each other, and the debts of the husband or wife to the outside world are known to the third party, the property owned by the husband or wife shall be used to pay off. The premarital property notarization originally means that two people who are going to get married go to notarize whether their premarital property is shared, so of course, one person cannot conduct premarital property notarization. But you can go to notarize what personal property you have. But if you can't prove your ownership of these properties, the notary office will not notarize the result for you. It will only notarize that you have shown these objects to them or that you have possessed them at that time. The marriage law itself stipulates that if there is no agreement between the two parties, the property before marriage shall belong to each other.
