(a) It is unlawful for any person or entity to:
(1) Solicit or request a referral fee from a real estate licensee without reasonable cause; or
(2) Threaten to reduce or withhold employee relocation benefits or to take other action adverse to the interests of a client of a real estate licensee because of an agency relationship.
(b) Reasonable cause allows a real estate licensee to solicit or request a referral fee but does not necessarily mean that the licensee has a legal right to be paid a referral fee.
