Bankruptcies are noted on credit reports. How much a bankruptcy might drop a person's credit score depends on how high the score was to begin with, but generally speaking, the hit can be as much as 100 to 200 points. Often scores are already dropping because people filing for bankruptcy may have already missed payments on debts. Chapter 13 bankruptcies are listed on credit reports for seven years from the filing date, while Chapter 7 bankruptcies are listed for 10 years from the filing date. This is because Chapter 13 bankruptcies require at least partial payment of debts owed.
