If your debt is $1.4M, you cannot file for Chapter 13 because your debt would is too much for a Chapter 13. 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 $383,175 and secured debts are less than $1,149,525.
