Most counties have a web site, you just have to find yours. If you go into google and type in your county and the clerk of courts you should be able to find it. Like I live in franklin county I would go to google and type:
franklin county clerk of court
and it would give me their web site. Once you get to their web site, look for something that says
Public Access click on it and it should give you a site like the one below, then you just type in your last name then your first name and anything that you have on you will pop up.
I picked a random name and put it in, you can do the same just to see how it works. It tells everything that you have done from going to court for Traffic tickets, criminal charges, dog tickets, civil suit, etc.

Oh if you have a warrent a pop-up will come after you find your name and it will say warrent on it, at least that is what happens on the one I use. I look up people a lot for others, that is part of what I do.
