Bankruptcy is a public record, so it will show up on your credit report. If you give someone the authority to pull your credit report, they're likely to see it. If you're an average, everyday person who files bankruptcy, it's unlikely that most people are going to know that you filed. You're not going to show up on a Google search, for example. You have to subscribe to an online court system to be able to view bankruptcy filings. The likelihood is that no one will know that you filed unless you offer the information, or you give someone the authority to pull your credit report.
