USPAP 2018-2019 Edition
© The Appraisal Foundation
In an assignment that includes only assignment results developed by the personal property appraiser(s), any
appraiser(s) who signs a certification accepts full responsibility for all elements of the certification, for the
assignment results, and for the contents of the appraisal report. In an assignment that includes real property
assignment results not developed by the personal property appraiser(s), any personal property appraiser(s)
who signs a certification accepts full responsibility for the personal property elements of the certification, for the
personal property assignment results, and for the personal property contents of the appraisal report.
When a signing appraiser(s) has relied on work done by appraisers and others who do not sign the certification,
the signing appraiser is responsible for the decision to rely on their work. The signing appraiser(s) is required
to have a reasonable basis for believing that those individuals performing the work are competent. The signing
appraiser(s) also must have no reason to doubt that the work of those individuals is credible.
The names of individuals providing significant mass appraisal assistance who do not sign a certification must
be stated in the certification. It is not required that the description of their assistance be contained in the
certification, but disclosure of their assistance is required in accordance with Standards Rule 6-2(g).
