Legal analysis: it can be determined. Handwriting identification refers to the recognition and identification of handwriting formed by people through writing activities. People's writing habits are concrete and stable, which are reflected in handwriting.

Legal basis: Article 25 of the Supreme People's Court's Provisions on Evidence in Civil Proceedings. If a party applies for identification, it shall submit it within the time limit for proof. In accordance with the provisions of the provisions of article twenty-seventh, unless the parties apply for re identification. If a party who bears the burden of proof for matters that need to be appraised fails to apply for appraisal or pay appraisal fees in advance or refuses to provide relevant materials within the time limit specified by the people's court without justifiable reasons, so that the disputed facts of the case cannot be identified through the appraisal conclusion, it shall bear the legal consequences of failing to prove the facts.
