What must any appraiser who signs any part of an appraisal report do according to USPAP?

An appraiser who signs any part of an appraisal report is required to sign the certification. This is a significant part of the Uniform Standards of Professional Appraisal Practice (USPAP), which emphasizes the importance of clearly stating the appraiser's responsibility and the basis of their opinions provided in the report. Signing the certification indicates that the appraiser has taken responsibility for the content of the report, affirming that the work was completed in accordance with applicable standards and regulations.

The certification typically includes key elements, such as affirmations about the independence of the appraiser and disclosures regarding any potential conflicts of interest. This layer of accountability ensures the integrity of the appraisal process, helping maintain public trust in the appraisal profession.
