If you sold a home five (5) years ago, you had an obligation to disclose all facts known to you about the home that could materially affect its desirabilty or the price paid for it by a willing buyer. If you knew before you closed escrow on the home that there were permit issues concerning it that were not disclosed to the buyer, and this buyer now sells it, you most likely will not have any liability to him or her at this point in time unless:1. the new buyer finds out after his or her purchase of the property from your buyer of some undisclosed permit issues with the home and files a lawsuit against your buyer.2. if such happens, the buyer of the house that you were in contract with could file a cross complaint for indemnity and contribution against you for not disclosing the permit issues when he or she bought the home.
