Note that I am not licensed to practice in your state.
If the credit card companies decides to sue you for the unpaid debts, then they can attach your bank accounts and also put a lien on your property.
In addition, keep in mind that creditors cannot garnish income if it comes from: social security benefits, retirement plan benefits and public assistance benefits.
You have the burden to prove that your income is exempt from garnishment. Since garnishment procedures vary from state to state, I would strong recommend that you contact an attorney in your area.
