Responsible for Loans after Divorce?

I reside in Winston-Salem, NC.  I was married to a woman for about six years in Davidson County, NC.  While we were both married we applied for and received funds from student loans.  I do not ever recall ever having co-signed for her loans nor did she co-sign for mine and upon divorce I did not assume any financial obligations for her debts.  Basically my best recollection was that the court order stated something like any property, loans, etc in my name remained mine and property, loans etc in her name remained hers.  It’s been about three years since the divorce and debt collectors are calling my parents and interrupting their lives.  They want my parents to give a message to my ex-wife or they want my contact information for me to give messages to my ex-wife.  My parents number is also on the do not call registry.  I have recommended they do not give them any information and report future calls to the FCC using their online form and under no cirumstances give them any information about me.  Is there any way they could pursue me for her debts?  I thought this was all taken care of when we divorced with the court order.  I am about to get married and my fiancee is thinking we will hounded by my exes debts for the rest of our lives and it’s quickly turning into a bummer.
You are not obligated to pay the loans (unless you co-signed), but why don’t you tell the loan companies how to get in touch with your ex-wife?  If you don’t know where she is tell them that.  Why should you run interference with with loan companies for your ex-wife.  The FCC won’t take any action here.  The do-not-call list does not apply in this situation.
