A broker whose listing has expired has given the seller the names of buyers who were shown the property... What listing contract clause requires this action...?

The due diligence clause typically refers to the responsibilities of the buyer to investigate the property and its condition before finalizing the purchase. It does not mandate the broker to provide buyer information upon expiration of the listing. Therefore, this clause is unrelated to the actions required of the broker after the listing period ends.

The procuring cause clause pertains to the broker's role in bringing about the sale of the property. While it relates to commission rights, it does not specifically require the broker to disclose buyer names after the listing expires. This clause is more focused on establishing the broker's direct involvement in the transaction rather than post-listing obligations.

The MLS permission clause concerns the use of Multiple Listing Service data and does not address the responsibilities of the broker towards the seller after the listing expires. This clause primarily deals with how a property can be listed and publicized within the MLS system, not with buyer information.
