Do photographic works need to be appraised in case of infringement?

Hello, the law does not expressly stipulate whether to apply for identification. You can decide whether to apply for identification according to the progress of the case.

In civil litigation, you can apply for an appraisal, and the parties can apply for an appraisal before the expiration of the time limit for adducing evidence. The people's court shall not allow the matters applied for appraisal to have nothing to do with the facts to be proved, or the facts to be proved have no probative significance.

If the judicial organ considers it necessary to entrust an appraisal institution to conduct appraisal ex officio without applying for appraisal. If the conditions for investigating and collecting evidence according to the functions and powers are met, the people's court shall entrust an expert to conduct appraisal according to the functions and powers, and after soliciting the opinions of the parties, designate an expert with corresponding qualifications to conduct appraisal.
