Forging someone else's signature constitutes fraud. If it is used to make perjury, it constitutes perjury. If it is used to forge government documents, the circumstances are even more serious. Signature has legal effect, and forged signature should bear legal responsibility. However, just forging a signature does not constitute a criminal offence, and it is necessary to comprehensively judge whether it constitutes a crime and what kind of crime it constitutes by combining the specific behavior, social harm and harmful consequences after forgery. The judgment of forging others' signatures in judicial practice should be determined according to the legal effect of forging others' signatures. If forging someone else's signature is to defraud money, it constitutes fraud. If you forge someone else's signature to sign a labor contract, it constitutes the crime of contract fraud. The specific punishment should be determined according to the specific criminal facts, and those who cause other consequences should be investigated for other responsibilities. The crime of contract fraud refers to the act of defrauding the other party of a large amount of property by fabricating facts or concealing the truth in the process of signing and performing a contract for the purpose of illegal possession.

Can forged signatures be identified?

Imitation signatures can be identified. Imitation handwriting is definitely different from the original handwriting. When imitating other people's notes, imitators often pay attention to imitating the basic writing form of handwriting, Lian Bi's action structure, microscopic characteristics, especially the dynamic pen pressure characteristics. This is difficult to fully grasp and use. Through the characteristics of pen pressure, we can make a breakthrough in judging whether the sample signature is written normally or imitated. The writing habit is concrete and stable, which is reflected in the handwriting. By checking the handwriting, we can determine whether the handwriting in the document was written by several people or by one person, and use the handwriting to identify the same person and confirm the authenticity of the document.
