How Many Years Must You Wait Before Filing For Bankruptcy A Second Time?

In California if you do a Ch.7 you have to wait 7 years, but if you do a 13, which is you pay back so much on the dollar you owe, what we did was after 3 years we were going to modify it (put something in) and then stop one and refile another one.  Trustee gives you a letter stating one is dismissed before starting the other one.

In the US, you can file for Chapter 7 bankruptcy again after six years has passed from the date of your last filing. You can file for a Chapter 13 bankruptcy can be filed any time.

I live in Ohio and my parents had filed bankruptcy and they were told that if needed you wouldn't be able to file again for seven years.
