After the court appointed and both parties agreed to do handwriting appraisal, why didn't the appraisal department accept it? The appraisal department said that there were handwriting signatures and fingerprints, mainly fingerprints. The proposed appraisal requirements are in line with the business scope of the appraisal institution, that is, there must be relevant personnel and qualifications, and the appraisal technology must meet the proposed requirements. Moreover, handwriting identification is also difficult. If the technical level is not enough, it is impossible. If it can't be done, the appraisal institution will naturally not accept it and can only invite another expert. Appraisal institutions can modify the appraisal requirements, but there is no basis for saying that fingerprints are the mainstay.
