Bankruptcy laws allow for people to switch to a different kind of bankruptcy- most often from a Chapter 7 to a Chapter 13 and vice versa, when and if circumstances allow for it. It can get tricky, its not like switching from one kind of a diet to another that you can just chose to do if you feel like it. Your bankruptcy lawyer proabably recommended one type of bankruptcy over another for a reason. Or maybe you did it yourself and it didn't work out the way you had hoped. Examine your reasons for asking the question to begin with and talk to an experienced bankruptcy lawyer about it. Bankruptcy law is not simple and you will want to make sure that you can do it and that the change will work out for you, before attempting to do it.
