I don't believe it can be done on-line, you should go to the relevant circuit court office and make a personal search there. You might ring first and let them know when you are coming so that they can look it up for you first- its a busy time of year so some advance notice would be good. Judgements are payable immediately or interest is due. Enforcing the payment is another matter and you could talk to the staff at the court house about it or consult a solicitor.
