Important notice containing information required under RESPA concerning the transfer of servicing.


You should be aware of the following information, which is set out in more detail in section 6 of the Real Estate Settlement Procedures Act (RESPA) (12 U.S.C. Section 2605):  During the 60 day period following the effective date of the transfer of the loan servicing, a loan payment received by Seneca Mortgage Servicing LLC before it’s date may not be treated by your new servicer – Nationstar Mortgage LLC as late, and a late fee may not be imposed on you.

Section 6 of RESPA (12 U.S.C. Section 2605) gives you certain consumer rights.  If you send a “Qualified Written Request” to your loan servicer concerning the servicing of your loan, your servicer must provide you with a written acknowledgment within 5 days (excluding legal public holidays, Saturdays and Sundays) of receipt of your request unless the action requested is taken within such period. A “Qualified Written Request” is a written correspondence, other than notice on a payment coupon or other payment medium supplied by the servicer, which includes your name and account number and your reason for your request.

If you want to send a “Qualified Written Request” regarding the servicing of your loan, it must be sent to this address: 

Nationstar Mortgage LLC
P.O. Box 650783
Dallas, TX 75265-0783

No later than 30 days (excluding legal public holidays, Saturdays and Sundays) after receiving your request, your servicer must make any appropriate corrections to your account and must provide you with a written clarification regarding any dispute.  During this 30 day period, your servicer may not provide information to a consumer reporting agency concerning any overdue payment related to such period or qualified written request.  This 30 day period may be extended by up to 15 days if before the end of such 30 day period the servicer notifies you of the extension and the reasons for the delay in responding.  However, this does not prevent the servicer from initiating foreclosure if proper ground exists under the mortgage documents.

Section 6 of RESPA also provides for damages and costs for individuals or classes of individuals in circumstances where servicers are shown to have violated the requirements of that section.  You should seek legal advice if you believe your rights have been violated.
