Apparently you are an agent yourself and have your license currently with a broker. If you do not have your license hung with a broker, it would be illegal by state law for that agent to pay you any commission even if you do hold a license. You must have your license with a broker, and any commission paid must be paid to your broker, not to you directly. As mentioned in the prior response all liability would be on the recipient agent, not you or your broker. If you are with a broker, I'm wondering why you didn't ask your own broker rather than agents you don't know who may make shameless pitches for you to abandon the person who you've been working with. If you are not with a broker, hang your license with one before you make your next referral or you are putting your license and the other agents license in jeopardy. By the way you did not say the other agent was a Realtor. He may or may not be, and it isn't relevant. We are talking about state law, not National Association of Realtors rules.
