Bankruptcy does eventually disappear I think, or if it doesn't there are legal requirements not to hold it against you after X years without a problem on your end. It's been a while since I've looked into it.

The irony, of course, is that the US Bankruptcy Code provides you can't declare bankruptcy again until 7 years have passed. So creditors theoretically have less risk during the period they generally refuse credit to the newly bankrupt. Of course none of that applies to business bankruptcy, where the old company is often dissolved but you're often looking to the same former principal(s) for personal guarantees of the new company's obligations.

There are a number of lenders who are willing to extend credit to those with a discharged bankruptcy (on terms far worse than someone with an 810 credit score, of course).
