Under what conditions should both spouses file under chapter 7?

Both husband and wife should file if one or more substantial dischargeable debts are owed by both spouses. If both spouses are liable for a substantial debt and only one spouse files under chapter 7, the creditor may later attempt to collect the debt from the nonfiling spouse, even if he or she has no income or assets. In community property states it may not be necessary for both spouses to file if all substantial dischargeable debts are community debts. The community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, and Washington.
