I believe there's a lot of unsettled debate with how to interpret the role of an appraiser in regards to litigation assignments. I believe that
@TerryRohrer is an experienced and competent appraiser based on the posts I read, however, the post about assisting the attorney with cross-examination strategy
may be considered advocacy by others. To be clear, I've been instructed to do the same by several other experienced appraisers as well as my mentor, with the added emphasis to do it while remaining unbiased and objective. More than likely, the attorney that hires you has probably expected that and received that assistance from other appraisers before.
