Sorry, yes, the broker in California charges a fee for service not paid by the carrier as a commission.
And, as Dan says, it does change the fiduciary responsibility and I don't think I have ever met a licensed insurance "broker" in California. I am sure that they exist, but have never met one.
The current vogue term in CA is "producer".
Yes, when I was in Cali I was NOT a broker. 'Producer' is indeed the proper term there.
