The Good Brokerage Practice guidelines were updated on September 30th, 2025, with the following addition to section 3.3:
"... However, the brokerage agreement does not need to be extended solely because the agreement expires after an offer has been accepted but before the sale can be completed."
Based on this guidance, it can be concluded that creating a continuation agreement would not be necessary if an offer for the listing has already been accepted. However, Linear always recommends following up-to-date guidance from official and legal sources.
