What is the Statute of Limitations in Tennessee for debt lawsuits

I purchased a sofa approximately 10 years ago. I paid on the sofa and then remarried. My husband advised me that he was taking care of this and I assumed he did since I have heard nothing from it in several years. In the mean time, I was divorced and moved. The house remained in my husband's name. I was in the house today and was served with court papers where I was being sued for the sofa. Is there a statute of limitations on a purchase like this from being sued---in Tennessee. Also, should I not be able to contact the agents for the furniture store and work out a settlement on this debt?
