Where do I go to check if I have warrents.

Police station...is there a reason you think you should have some? They don't expire or go away, so if you had any that were unanswered to in the past, they are still active and valid.

Or the court where you were arraigned.

There are some web sites, but none of them are 100 percent, An actual check at a police station is the only way to be 100 percent.

If you are afraid of arrest, arrange for an attorney to check for you
