(c) No provision may be inserted in any contract for representation that would obligate the person signing the contract to pay a fee, commission or other valuable consideration to the broker, after the contract's expiration date, if the person subsequently enters into a contract for representation with a different broker.

(d) Every licensee shall disclose in writing, on the notice of agency relationship form promulgated by the commission, whether the licensee represents the seller, the buyer or both. The disclosure shall be made prior to any person signing any contract for representation by a licensee or a contract for the sale or purchase of real estate.
