Going to court without a lawyer is not a real clever thing to do if you are not trained as a lawyer and do not know how to try cases in court. Even inexperienced licensed lawyers can look like fools in court. I tried a comp case recently against a lawyer who has been practicing for less than 3 years and that lawyer did not know what he was doing in court. The judge was getting more and more irritated with that lawyer as the trial went on and the young lawyer kept screwing up.
At the end of the trial, the judge announced how he was thinking about the issues in the case. The judge revealed that the inexperienced lawyer was basically getting nothing good from the judge for his client. Why? Because the inexperienced lawyer had done a poor job of presenting the evidence on behalf of his client. His client is therefore going to lose.
If you can do better than an inexperienced lawyer, then you may win. It is not impossible. But don't count on it. If you have a decent case don't screw it up by representing yourself. If you have a decent case, then you have something to lose. Your best bet is to hire the best work comp lawyer you can.
