My disabled adult son was served with a summons to appear in court for a delinquent credit card. He has a mental illness and is not capable of responding to it. I contacted the Attorney office initiating the summons but they will not talk to me. He has very little money, just a small disability check. What do I do?

Why with a mental illness was he using a credit card?

Are you his guardian since he has a mental illness, if he is capable he can sign a power of attorney to you, to talk to them about his debt.

But if he has a credit card and if he was charging things on it, he needs to pay it or they will go to court and get a judgement against him.

You can't contact the plaintiff or their attorney since you are not a party to the suit unless you are the legal guardian or have a POA.

Chuck makes a good point about using this card, was this use prior to the illness taking hold?

The summons needs to be answered with an Intent to Defend. I would show up in court with your son and an affadavits from your son's physician detailing his illness.
