Therapy and tellie are correct I only have hearsay, and I just got off the phone
with the surveyor
and he adamantly denied that he disclosed the value. Furthermore he reiterated much what boatpoker and others mentioned about me being a client and the confidential nature of our agreement. He also said that the seller has since called him and directly asked him at what he valued the boat and he of course told him he could not disclose that.
Who knows, I could be caught between two liars, we will never know for sure, though I am inclined to trust the surveyor
, as he seems very professional.
Thanks for all the info and lively debate.
