I don't know about other states, but in California if you sue a corporation in small claims court, they can NOT send an attorney:

Corporation or other legal entity — A corporation or other legal entity (that is not a natural person) can be represented by a regular employee, an officer, or a director; a partnership can be represented by a partner or regular employee of the partnership. The representative may not be an attorney or person whose only job is to represent the party in small claims court. An attorney may appear to represent a law firms as long as that attorney is a general partner of the law firm or is an officer of the corporation. However, in both instances, all the other members of the partnership and all the other officers of the corporations have to be attorneys as well.[1]
