Is there any other way that someone can see my criminal history?
Yes. Because most criminal records and criminal case information is technically public, people in the general public could access on their own most legal paperwork filed in court or with a government agency. For example, anyone can go to the local courthouse, look up your criminal case and make copies of the documents in the court file.
But it is very unlikely that most people would go down to the courthouse to look you up for an apartment or job! Keep in mind that the information is likely scattered across hundreds of locations, so someone would really have to know exactly what they are looking for to actually find it. That’s why most people use professional background check companies to do the investigating for them—and that’s why these companies and the background checks they create are regulated by state and federal laws to protect you!
