Rules and practice changes from the recent lawsuit settlement agreement will take effect Aug. 17, the National Association of REALTORS® said Friday in a message to members.

Those changes include prohibiting offers of broker compensation or commission on the MLS and requiring written agent agreements with buyer clients. NAR previously said those changes were expected to start in mid-July.

The changes are part of the $418 million settlement NAR made in the Sitzer-Burnett case in Missouri. The settlement was announced in March, and since then, other defendants and large brokerages have announced their own settlement agreements. 

“We are committed to working together to navigate these adjustments and providing as much guidance to our members as possible,” NAR Chief Legal Counsel Katie Johnson said in the message to members. “As further details emerge, additional materials will be shared and posted to facts.realtor.”
