I'm not an attorney, but to my knowledge, no. The whole concept of Small Claims is that you don't have to have an attorney to litigate, nor defend yourself. The courts interpret that as you don't get to have an attorney at trial. Now, he may sit in the gallery, but if he is communicating with you, the magistrate can expel him from the court room. If one party brings an attorney, and the other doesn't that sets them at a disadvantage. Usually in Small Claims, the court holds the hands of the litigants so to speak. In Limited Actions, that is different. You can have an attorney, but I've seen some appear Pro se.
What may differ by state is the plaintiff's ability to collect more than just damages and more than purely money. In a regular action you can lay claim to non monetary items to be sold at auction to retire the debt incurred by the defendant at trial. O.J. Simpson is a case in point. The items he was trying to secure at gun point in Vegas were seized in relation to the trial for wrongful death he had lost.
Here in Kansas, and surrounding states, you can only seize money. You can't seize personal items to secure the debt. You can only sue for actual damages and in Kansas the limit is $4K.
What I didn't mention previously is that if you are an LLC you have to have an attorney. You can't appear Pro se, so in that one case, you can have an attorney. This is because of the masking a company does for its share holders. Your LLC may only have a single share holder, yourself, but the courts don't know this and so require you to have an attorney so that all of the share holders are represented.
