While there is no right to be afforded free legal representation in civil court in most US jurisdictions (some do) and a civil court can render rulings and judgments against parties who are not represented by counsel, a civil court cannot prohibit a party from having legal representation, which is what your comment seems to suggest.
A civil court can render a ruling against a party if the party is not present, but it will typically go to great lengths to ensure that notice is given to parties before doing so (pleadings served to last address by process server, notice published, etc.). There are typically strict requirements that have to be met before civil court can render a ruling or judgment without a party present, especially where there is no indication that the party has received notice first.
A lot of anecdotes about drastic judgments and rulings being handed down by civil courts happen when parties ignore notice of the proceedings. There are a lot of rules for handling cases in civil court and they are grounded in the constitutional right to due process. Notice and due process are taken really seriously in most US jurisdictions. Federal Courts are especially strict about following the rules.
