13 bankruptcy attorneys are listed in Tucson. They file Chapter 7 liquidations, Chapter 13 repayment plans that can stop a foreclosure and cure arrears, and business reorganisations under Chapter 11.

Ask which chapter fits and why, and what the quoted flat fee covers once court filing fees and mandatory credit counselling are added.
