Legal analysis: signature has legal effect, and forging others' signature will bear legal responsibility. If it is used to forge receipts and contracts, it constitutes fraud, if it is used to create perjury, it constitutes perjury, and if it is used to forge government documents, the circumstances are even more serious. Generally, it is a civil dispute and is not considered a crime. Whether it constitutes a crime depends mainly on the motivation of the perpetrator, the behavior carried out and the consequences caused.

Legal basis: Article 10 14 of the Civil Code of People's Republic of China (PRC). No organization or individual may infringe upon the name right of others by interference, embezzlement or counterfeiting.
