If I have previously filed for bankruptcy am I eligible to file again now?

A prior Chapter 7 bankruptcy discharge prevents another Chapter 7 case for 8 years from the date of the first case filing.  A prior Chapter 13 discharge prevents a Chapter 7 case for 6 years unless the case repaid 70% of the debt and was filed in good faith.  A prior Chapter 13 Discharge prevents another Chapter 13 Discharge for 4 years.   Consult with an attorney to determine if any of these rules apply.
