Answer:
Yes
Step-by-step explanation:
In this specific scenario, it can be said that Yes the seller can refuse to pay the broker a commission. This is because the broker's license ceases to be in force when the broker changes his address without notifying the FREC within 10 days. Therefore, since the broker moved and did not notify the FREC where he moved to, and did not register his new address then the seller is within his rights to refuse payment to the broker.
