In order to be eligible to file for Chapter 13 Bankruptcy one must be an individual with "regular income." Corporations, partnerships, estates, and trusts are not eligible to file for Chapter 13. But individual operating their own business as a sole proprietorship (unincorporated) are generally eligible to file chapter 13 to deal with their personal and business debt.
A husband and wife can file a joint Chapter 13 case. The filing of a joint petition does not automatically result in the substantive consolidation of the two debtors' estates.
