Is there any department to appraise the handwriting and printing of calligraphy?

You can go to your local judicial administrative department (judicial bureau) or visit its website to inquire about the authorized and qualified judicial authentication institutions in the "judicial authentication" project, and then you can call directly for consultation.

Handwriting appraisal must be carried out in an appraisal institution approved by the judicial administrative department. (It is recommended not to do it in the public security department, which may lead to the risk of rejection. If you can do it in person in the appraisal institution before the lawsuit, you risk being rejected by the court.

If you apply to the court for appraisal in litigation, you will usually adopt the appraisal conclusion. The appraisal fee is generally around 1 1,000 yuan. If in the lawsuit, the applicant pays first, and finally the losing party bears it.

Comprehensive evaluation is to scientifically analyze the numerical values of the same characteristics and different characteristics of sample handwriting and sample handwriting, determine the sum and nature of the coincidence points and differences between them, and then make static conclusions. The method of judgment is generally to start with textual research. When identifying any handwriting, there will be certain differences in characteristics. The key point of judging the difference is to determine the nature of the difference.

Its nature has two aspects: essential difference and non-essential difference. Non-essential differences indicate that the proportion of quantity and quality of different features between sample handwriting and sample handwriting is small, while essential differences indicate that the proportion of quantity and quality of different features is large. The former generally shows that they are a reflection of different people's writing habits.

Handwriting identification should not only focus on the judgment of differences, but also on the judgment of overlapping points. It is unscientific to affirm the same conclusion after confirming that differences are non-essential.

Coincidence points can also be divided into essential coincidence and non-essential coincidence. If the quantity and quality of the same characteristics of the sample handwriting and the sample handwriting are absolutely dominant, it constitutes essential conformity; If the proportion of the same feature in quantity and quality is small, it belongs to non-essential conformity.

After judging the differences and overlapping points, if there are essential differences and non-essential differences between the sample handwriting and the sample handwriting, or the results of essential differences and non-essential differences, it can be concluded whether the sample handwriting and the sample handwriting are written by the same person.
