Chapter 13 of the bankruptcy laws generally enables a person with regular income to stop his creditors’ collection efforts while he pays his debts, in whole or in part.

Unlike a Chapter 7 bankruptcy, which is filed for the purpose of discharging a person’s unsecured debts, a Chapter 13 bankruptcy allows a person who has equities to keep his property and assets while paying other debts off over time.

Chapter 11 bankruptcy is available to any business, whether organized as a corporation or sole proprietorship, or individual with unsecured debts of at least $336,900.00 or secured debts of at least $1,010,650.00, although it is most prominently used by corporate entities.

I would speak to an attorney to determine which is best for you.

Good luck!
