I am recently divorced in Arkansas. The 2008 2500 HD GMC truck was ordered sold. I have not seen this truck in almost 2 years because my ex-husband drove it out and hid it. Now his mother has filed a mechanics lean for almost 7,000.00 because she loaned my ex money to buy a new motor. She filed the lean against myself and my ex and I never knew or consented to the motor. What can I do to remove the lean?
