Excerpts: When a real estate appraiser is called to testify in a court, it could be as one of two types of witnesses. If you are called to testify as an appraiser, it’s important to determine at the time of the request which of the two types you will be: fact witness or expert witness appraisers.
A fact witness is one who testifies only to that of which he or she has firsthand knowledge and who describes only facts (as opposed to expressing opinions). There is no formal definition of a fact witness….
As an expert witness appraiser, you are allowed to express opinions. In fact, your opinions are the very reason for your testimony. The opinions are to be based on the expertise afforded by “scientific, technical, or other specialized knowledge.”

My comments: This is a never-ending hot issue for many appraisers. They don’t understand the difference. The difference is you get paid a minimal fee as a fact witness (similar to a witness of an auto accident, for example). As an expert witness, you are paid very well for prep for expert witness testimony, depositions, waiting outside the courtroom, and testifying. I have written about this in my paid Appraisal Today newsletter.
