I have an unsecured line of credit that I am going to stop paying on. What can they do to collect the debt?

I have an unsecured line of credit that I am going to stop paying on. What can the creditor do to collect? I am not working so I don't have income that they can attach. I do however have ets. Can they attach my ets if they are in both my name and my husbands? Can they attach my business ets?
