@David M. South Carolina is also an attorney state, but the attorneys here are minimally involved in the actual transaction. Their primary role is to complete the transaction. They prepare closing documentation, handle escrow funds and adequately record the sale. Some times, attorneys will act as referees if there's a disagreement, but they usually want to stay out of those conflicts and leave it to mediation or a court to decide if it's a serious issue.
The agents are responsible for all the negotiations and coordinating all the terms of the contract. I've seen plenty of people hire a RE attorney just to help them draft offers, but the attorney usually won't even deliver the thing to the listing agent.
I can totally understand why the public feels negatively towards agents. Many agents I have to deal with don't seem to know anything about actual RE law. They can also be unprofessional, appear greedy and be terrible communicators. I think the problem is that these big companies have trained up legions of desperate agents to think there is actually a standard commission rate and have failed to teach them that real estate exists outside of their myopic little bullpens. I can't tell you how frequently I have to explain things to agents from big companies. They don't train these agents to be educated on the scope of real estate. They think their company's policies are actual law. Now us little guys who rarely see a full 3% commission are having to adjust.
