A month later, the appraisal agency made the appraisal conclusion and stamped it with the official seal, but the appraiser did not stamp or sign it. Finally, the court did not accept the appraisal conclusion on the grounds that the appraiser did not stamp or sign. Excuse me: the appraiser did not seal the appraisal conclusion and was not accepted. Can he ask for a refund of the appraisal fee? Readers: Judicial authentication institutions belong to social intermediary institutions. The parties personally or through the judicial organs entrust the matters that need to be appraised to the judicial authentication institutions, and the appraisal expenses shall be borne by the parties, and the authentication institutions shall issue payment invoices to the parties, thus forming an entrustment contract relationship between the parties and the judicial authentication institutions. Article 72 of the Civil Procedure Law of People's Republic of China (PRC) and Article 35 of the General Rules of Judicial Appraisal Procedure of the Ministry of Justice respectively stipulate: "... the appraisal department and the appraiser shall submit a written appraisal conclusion and sign or seal the appraisal book. If the appraiser authenticates, the unit to which the appraiser belongs shall affix a seal to prove the identity of the appraiser. " "Judicial authentication documents shall be signed or sealed by judicial appraisers. ..... Judicial authentication documents shall be stamped with the special seal for judicial authentication of judicial authentication institutions. " It is the legal obligation of the appraiser to sign or seal the appraisal documents. Because the appraiser did not sign or seal the judicial authentication document, the judicial organ could not confirm the appraiser's qualification, and then could not accept the appraisal conclusion on the judicial authentication document, causing losses to the parties, and the appraiser was obviously at fault, so the appraiser made the authentication document within the scope of performing the duties of the authentication institution. The legal consequences shall be borne by the entrusted evaluation institution according to law. Therefore, according to Article 406 of People's Republic of China (PRC) Contract Law: "If the paid entrustment contract causes losses to the client due to the fault of the agent, the client may demand compensation for the losses.
