Abstract
The research has shown that property valuer’s duty of confidentiality is one of the legally protected professional privileges explicitly regulated in the system of law. The analysis of the legal regulation of the duty of discretion imposed allows for stating the simultaneous co-existence of both the material premise as well as formal confidentiality, so the conditions for treating this secrecy separately have been met. Its substantive scope has been regulated narrowly and embraces only property valuers. The objective scope of the property valuer’s secrecy was generally and broadly extended to “information obtained by a property valuer in connection with the exercise of professional duties”. In order to reconstruct the protected scope of information the article analyses the professional duties performed by property valuers and their authorizations to access certain information.
