it cost 15 bucks for a fbi background check..... that info contains all "system" records but..... theres a trick. sometimes court records do not go into the "system" based on you not gettin in trouble for so many months or years an so on. kinda like a probation.... but these records will show up when whoever is screening you calls the local court houses..... generally they will call all courts in the surrounding counties and have the records searched...based on the zip codes you give with your background check paperwork.
there are ways around passing a background check but its prolly not a good thing for me to tell ya.
generally you can check your record online for free if you check circuit court(criminal) and traffic court online on the states court records. it is public info
