If you are a real estate Broker suing a Seller or another Broker over a real estate sales commission, or defending against such a claim, you deserve to be represented by a qualified real estate attorney.
Hire an attorney who is familiar with how the process works in your particular forum, not just with what real estate laws require –any attorney can look up the law. Arbitration panels many not always follow case law.
Just as critical is an attorney who is aware of what precise evidence to develop, what questions to ask during the deposition/hearing/trial or Arbitration to increase your likelihood of prevailing.
I serve as an Arbitrator and regularly hear and decide commission disputes.
As a neutral decision maker, I sometimes see key evidence not being addressed by a party. The Elephant in the room. Evidence that could have helped them win the case. As a neutral, I am not allowed to advocate for any party. All I can do is rule upon the evidence presented.
