Final answer:
Without a signed agreement, the real estate broker may have difficulty enforcing payment of their commission.
Step-by-step explanation:
Since no written agreement was signed between the seller and the real estate broker, it may be difficult for the broker to enforce the payment of their commission. In most cases, real estate brokers rely on a signed contract outlining their terms and conditions with the seller. Without a signed agreement, the broker may not have legal grounds to demand payment from the seller.
However, it's important to note that real estate laws and regulations vary by jurisdiction. Some jurisdictions may recognize verbal agreements or have specific rules regarding real estate broker commissions. It would be advisable for the broker to consult with a lawyer or legal expert to determine their rights and options for recovering their commission.
