Ang is right, they cannot just garnish wages because they want to. What attorney are you dealing with, a local one?
Did you not have insurance? They will say they won't take payments, that they want it all, but usually if you send them a payment each month with a letter saying you are paying xx dollars on the xx day of the month-they won't turn it down.
But be sure they have the authority to be collecting on this debt first. After they validate, if they do, you can go from there. Alot of attorneys are also collecion companies and buy or collect on debts past the SOL, hoping you won't know your rights.
If this is a valid debt, and worse comes to worse, if they file suit, the judge will set up payments anyways. And if you get served a summons, you can file a hardship answer if this will be a hardship on you..Good Luck..KAren
