While the law allows any party to represent themselves, thus "Pro Se", a non-lawyer can not act in any legal capacity for that Pro Se litigant; in other words, can not "co-rep" the Pro Se litigant. It is always extremely dangerous to represent oneself in a legal proceeding; however if you have a difficulty or impediment in being able to communicate, that only serves to magnify the dangers of doing so. You should reconsider retaining a lawyer.
Hire a lawyer and do not represent yourself if you can avoid it at all costs. You either are in pro per and rep yourself or you have a licensed attorney. You can't just bring a friend into court to argue your case for you? You can bring and ask permission to present witnesses? if you have trouble articulating your position, submit a legal brief outling the current and valid law on your subject and the facts. You can attach documents and a declaration under oath from you and your witnesses outlining the facts and stating the documents submitted are true and correct copies of the originals. You will need a copy for the court and yourself and one for each other party to the case.
