Which condition makes a listing valid?

• A. It is in writing and a true copy has been delivered to all owners
• B. It has no expiration date
• C. It must be posted on MLS
• D. It must be signed by both buyer and seller

Answer: (A)

The essential factor is that a listing agreement must be in writing and there must be a true copy delivered to all owners. This written form provides a clear record of the authority given to the broker, the terms of the listing, and the owners’ consent. Oral listings aren’t enforceable in real estate practice, so the writing requirement is what makes the listing valid.

The other elements aren’t what establish validity. An expiration date is common and prudent, but its absence doesn’t by itself render a listing invalid. MLS posting is a marketing tool and not a condition for a listing’s validity. Signatures from both buyer and seller aren’t required for a listing, since the agreement is between the seller and the broker, not the buyer.
