Mr. Wimpelberg,
That will be fun for most appraisers when a judge asks them for a copy of that confidentiality agreement with their client and it dawns on them they don't have one. In the next moment they will be explaining to the judge they meant to say USPAP requires it and they don't really have any signed agreement with their client. So after getting egg all over themselves, and proving they make verbal mistakes while on the witness stand, the judge is going to ask this witness how it is the witness knows what questions are going to be asked before they are asked? As the questions may regard nothing confidential at all, and if they do the witness is to let the judge worry about that. So with more egg on their faces the appraisers that do that will have just politely been told to turn around and answer the questions.
Webbed.
