How will filing bankruptcy affect my credit?

Generally we see clients with lower credit scores (450 – 550) increase 50 – 100 points after filing.  Clients with mid range scores (600) stay about the same and higher credit scores (700 or above) decrease 40 -80 points. We have started referring our clients to www.creditkarma.com to check their credit score prior to filing. This allows the person to see first hand how their credit score is affected. We also pull all clients credit reports and credit scores prior to filing and use a bankruptcy program that estimates how clients credit score will change.
