Any individual, even if self-employed or operating an unincorporated business, is eligible for chapter 13 relief as long as the individual's unsecured debts are less than $360,475 and secured debts are less than $1,081,400.  These amounts are adjusted periodically to reflect changes in the consumer price index. A corporation or partnership may not be a chapter 13 debtor.
