Chapter 7 bankruptcy takes approximately 4 – 5 months if you do not have any assets that the trustee wants to sell and there are no other issues (e.g., an adversary proceeding to determine non-dischargeability of certain debt).
Chapter 13 bankruptcy takes either 3 or 5 years depending on your income. If your gross income during last 6 months is less than median income in the state where you live, your Chapter 13 will take 3 years. If your gross income for last 6 months is above the median income in the state where you live, your Chapter 13 will take 5 years. The median income in Arizona for 1 person is $47,360, for a two-person household is $60,761, for a three-person household is $62,013 and for a four-person household is $74,317.
