No, they do not have the right to garnish wages on a claim of this nature. It is also against the Fair Debt Collection Practices Act for them to threaten this since it is not available in SC. Debt collectors cannot threaten you with actions they are not allowed to take.
More good news, if the car was repossessed in 2006, it is likely they are outside of the statute of limitations to pursue you for the deficiency. The statute of limitations is three (3) years which will run from the date of last payment or the date the car was sold, whichever occurred later.
If you make a payment now, you will renew the statute of limitations or possibly, if you promise to pay the debt in writing, you may extend the statute. So be careful with how you proceed.
I am assuming they do not already have a judgment. If they file suit and you are served with papers, be certain to file an answer raising statute of limitations as a defense. If they do file suit, you may want to retain an attorney to assure all your defenses are presented and you do not fall victim to certain lawsuit “traps”. If you are served, give me a call, I can help.
I hope this information is helpful.
