Over a million borrowers defaulted on student loans last year. Many of those carrying this debt file for bankruptcy. In fact, an estimated one-third of bankruptcies involve student loans. But what many people might not know is that in bankruptcy, student loan debt is rarely forgiven. One researcher found that of over 230,000 student-loan borrowers who filed bankruptcy in 2007, under 450 — less than 0.2 percent — even tried to discharge their education loans.
