A listing agreement is a legally binding contract between a homeowner and the real estate agent or broker who will be listing the property for sale. Here is a checklist consisting of some documents for listing and tasks to get that ball in motion.This part of the listing agreement is all about the seller agreeing that they have the right to sell the property free and clear (other than a mortgage). I listed my property for sale with a broker and the broker has done nothing about selling the house. Can I break my contract and list with someone else? Seller will sign and notarize two (2) copies of the mineral deed. Seller will fill out and sign the wire transfer details form. Broker is not authorized to execute any document in the name of or on behalf of Landlord concerning the Property. 12. In addition to MLS Listing, Broker will advise and represent Seller in all contract and repair negotiations and complete all necessary documentation. I am changing sponsoring brokers.
