4.13.4. Attorneys.Attorneys play a critical role in appraisals for federal acquisitions, whether or not litigation is involved. Legal instructions are necessary on a variety of valuation issues addressed throughout these Standards, such as ownership and title questions affecting the larger parcel determination (Section 4.3.3) or the proper application of the scope of the project rule to exclude government project influence on market value (Section 4.5). To do so, attorneys—whether agency counsel, Department of Justice attorneys, or landowners’ counsel—must often engage in nuanced discussions with appraisers to determine what legal instructions are necessary and appropriate. Agency counsel should consult the U.S. Department of Justice for assistance on novel or complex issues.
