In regards to communications with third parties, a collection agency may not contact other people except to locate you.  When contacting other people, the collection company must state his or her name and that he or she is just confirming you location information.  The collection agency may not give their company name unless they are asked.  They are not allowed to state whether or not you owe a debt.  A collection agency may not contact a third party more than one time unless the person allows additional communication.  If the collection agency thinks the information was wrong they can call again.

Can A Creditor Call Third Parties If I Have An Attorney

If a creditor or collection agency knows that you have an attorney, they may only contact the attorney.  They may only contact you if they have your permission to do so.  The original creditor is always allowed to contact you.  They are under a different set of rules than a collection agency would be.
