Frequently Asked Questions
What is Clear Cooperation Policy?
NAR rule requiring listings to be submitted to the MLS within 1 business day of any public marketing. Public marketing includes signs, flyers, social media, and digital ads. Office exclusives and coming-soon listings are interpreted differently by each MLS.
Which MLS rules cause the most TC errors?
Status update timing (Stellar MLS), photo minimums (NorthstarMLS), withdrawal vs cancellation distinction (most MLSs), and Clear Cooperation interpretation. Status-update lateness is the most common because it requires the TC to know contract execution dates in real time.
Can MLS compliance be automated?
Partially. ReBillion tracks contract execution dates, deadline triggers, and required status updates per MLS. The TC still confirms manual updates to MLS interfaces, but the prompts and deadlines are automated.
What is withdrawal versus cancellation in MLS terms?
Withdrawal: listing is taken off the active MLS but the contract between seller and broker remains in force. Cancellation: contract is terminated; listing is removed and the broker cannot relist without a new contract. Confusing the two creates significant compliance exposure.
Are MLS fines collected at the brokerage level?
Yes. MLS fines are assessed against the listing broker even when the TC made the operational error. Some MLSs publish a fine schedule; most use case-by-case discretion. Repeat violations escalate.
