There are many websites, including the one listed below and the official U.S. Courts website, where you can get basic information about Chapter 7 bankruptcy. However, a local bankruptcy lawyer might be the best source of the information you're looking for, and many offer free initial consultations. A local bankruptcy lawyer can walk you through the Chapter 7 means test to determine your likely eligibility for Chapter 7, and can look at your debts and assets and explain which debts are dischargeable and which assets are exempt.
Two other sites that I would recommend are legalconsumer .com and the U.S. Courts Bankruptcy information site. Both sites are listed below. Nolo press also publishes some good bankruptcy guides. After you have done your research, make an appointment with a local bankruptcy attorney in your area and discuss how the bankruptcy code applies to your particular circumstances. Many bankruptcy attorneys off free initial consultations.
