To enforce a protective clause beyond the expiration of an exclusive listing contract, there is a provision for the protective clause in the listing contract which establishes a definite protection period. In writing and prior to the expiration of the listing, the broker furnishes to the listing party the names and available contact information of persons to whom the property was presented during the active term of the listing and for whom protection is sought. Delivery is by personal service with written acknowledgment of receipt, or by both regular mail and certified mail, return receipt requested.
