My husband has a lien on some property that I acquired in our divorce.loan company will not discuss the loan with me and my ex will not authorize what can I do

You mean that there is a judgment against your ex-husband and that judgment has been recorded as a lien against property you acquired during the divorce? Were you aware of the lien during the divorce? If not, you may be able to go back to court and get the divorce court to order your ex to clear the lien.
