Will my neighbor find out that I filed for bankruptcy?

Typically, your neighbor will not find out that you filed for any type of bankruptcy protection.  Although bankruptcy is public record, it is not widely published in any newspaper.  It is found online and somebody who wants to search the Clerk of the United States Bankruptcy Court website could find out whether or not you have ever filed for bankruptcy.  However, the likelihood of one of your neighbors out of the blue contacting the Bankruptcy Court website and searching around for your name is very rare.
You should rest assured that filing bankruptcy is your federal right.  It is protection.  It is your right under the Constitution to either get a fresh start or to repay your debt over time.  Bankruptcy filing has led to such wonderful results for people.  It has taken people who are thousands of dollars in debt, struggling for year after year after year, subject to bank garnishments, wage garnishment, creditor harassment, and turn their whole situation around by simply filing for bankruptcy through a licensed attorney in their local area.
Under chapter 7, you get a fresh start.  Don’t worry if your neighbor is going to find out.  They are typically not going to do so.  And if they do, you should hold your head up high that you fell into a situation but you rectified it and you took advantage of existing federal laws to turn your situation around.  Under chapter 13, you might be saving your home from foreclosure.  Again, you should not be embarrassed about your elected to go for your federal right to save your home from foreclosure.  You have the ability to reorganize over a three to five-year payment plan.  By saving your home, you are actually helping your neighborhood.  And helping your neighbors increase the value of their property so that your neighborhood doesn’t become a blight area.
So typically, no one will find out about your bankruptcy unless you want them to know.
