When you fill out your bar application you have to check boxes for late credit payments. Apparently this is to see if you are financially responsible. If you have any credit blip you admit to, and you have to admit to it by the way or it is an integrity issue, then chances are there is going to be a character and fitness review. This is something your law school does not prepare you for. I know several friends right now whose admission is being delayed until the Board of Bar Examiners can do some digging.
Apparently they ask for a current credit report, a financial affidavit and other facts about why you were late on your payments. They do not allow you to send in this additional information here in Oregon until after you know that you have passed the bar. Then you have 3 1/2 days to send back the requested information. Fun times, right? Seems that this should be requested beforehand. If there is a serious issue to bar admission, then how can the applicant actually remedy the issue in 3 1/2 days?
Anyway, all this to say, if you pay your bills on time --- even if you have to go to a blood bank to sell your plasma, then do so please.
