Does anyone know the address to the National Collegiate Student Loan Trust which is a Delaware Trust?

Contact a consumer law or debt collection attorney in your area. I know nothing about this area of law, but I did run across this website that may be useful: http://www.consumerhelpcentral.com/national-collegiate-student-loan-trust-defense-basics/

Go to the following link (the Delaware Department of Corporations) and search for "National Collegiate Student Loan": https://delecorp.delaware.gov/tin/GINameSearch.jsp Click on the appropriate Trust you want to sue, and you will see the registered agent for service of process. Remember, there are about a dozen NCSL Trusts from the years 2003-2009. Good luck.
