Notice of Error

Written borrower notice requiring a mortgage servicer to investigate an asserted servicing error and explain the result.

A notice of error, or NOE, is a written borrower notice identifying a specific mortgage-servicing error that the servicer must investigate and address under Regulation X.

Why It Matters

Servicing mistakes can affect the principal balance, fees, escrow, delinquency status, credit reporting, loss mitigation, and foreclosure activity. A phone call may resolve a simple problem, but an NOE creates a documented review path with acknowledgment, investigation, and written-response duties.

The notice must identify the borrower, give enough information to identify the mortgage account, and describe the error the borrower believes occurred. It should state concrete facts such as the payment date, amount, confirmation number, disputed charge, statement period, or communication involved. The borrower does not need to know the servicer’s internal cause before asserting the error.

The Regulation X procedure concerns servicing. A complaint that the original lender made a poor underwriting decision, disclosed an origination fee incorrectly, or later sold the loan is not automatically a covered servicing error under this procedure.

Where It Appears in the Borrower Process

Borrowers use an NOE after closing, once a servicer is administering the account. Covered errors include certain failures to:

  • accept, credit, or correctly apply a conforming payment
  • pay taxes or insurance from escrow on time
  • refund a required escrow balance
  • provide an accurate payoff balance
  • avoid unsupported fees or force-placed insurance charges
  • transfer servicing information accurately
  • provide required servicing, foreclosure, or loss-mitigation information

The regulation also includes a catch-all for other errors relating to servicing. That does not turn every dispute involving a mortgage into a covered error; the issue still must concern administration of the existing loan.

How to Send a Useful Notice

IncludePractical purpose
Borrower nameIdentifies who is asserting the error
Loan number or other account identifierConnects the notice to the correct mortgage
Clear description of each errorDefines what the servicer must investigate
Dates, amounts, and supporting recordsMakes the account event easier to trace
Requested correctionTells the servicer what result the borrower expects

Use the servicer’s designated address for notices of error when one has been established. It may be listed on the mortgage statement or account website. A note written only on a payment coupon does not have to be treated as an NOE. Keeping a copy and delivery record helps preserve the timeline.

General Response Timeline

Servicer actionGeneral timing
Acknowledge receiptWithin 5 days, excluding Saturdays, Sundays, and legal public holidays
Resolve an inaccurate payoff-balance errorGenerally within 7 days on the same excluded-day basis
Resolve most other covered errorsGenerally within 30 days on the same excluded-day basis
Extend an eligible 30-day responseUp to 15 additional days after written notice explaining the extension

Some foreclosure-related errors use the earlier of a specified response period or the foreclosure-sale date, and not every deadline can be extended. A servicer can also use an early-correction path when it corrects the asserted error and notifies the borrower in writing within the initial five-day period.

After investigating, the servicer generally must either correct the error and explain the correction or state that it found no error and explain why. If the servicer finds no error, the borrower can request copies of the documents the servicer actually relied on, subject to limits for confidential, proprietary, or privileged material.

Notice of Error Compared with Nearby Terms

TermWhat it answers
Mortgage StatementWhat did the servicer show on the regular account statement?
Notice of ErrorWhat servicing mistake is the borrower asking the servicer to correct?
Payment ApplicationHow did the servicer say the money was posted or held?
Escrow AnalysisDid the servicer recalculate taxes and insurance correctly?
Mortgage ServicerWhich company must review and answer the notice?
Qualified Written RequestDoes the writing satisfy RESPA’s QWR definition and function as an NOE, RFI, or both?

Practical Example

A borrower paid $2,200 through the servicer’s online portal and received a confirmation. The next statement shows the money in suspense, a past-due installment, and a late fee. The borrower sends an NOE to the designated address, identifies the payment date and confirmation number, and asks the servicer to apply the payment correctly, remove the resulting fee, and correct the account history.

The same letter can include an RFI asking for the transaction history and payment-application records. The error claim and records request remain distinct even though they travel in one envelope.

How It Differs From Nearby Terms

Notice of error differs from Mortgage Statement because the statement is the servicer’s account summary, while the notice of error is the borrower’s written challenge to a specific mistake.

It also differs from Request for Information. A notice of error asks the servicer to fix or review an error, while a request for information asks for account-related information or records.

It also differs from Payment Application. Payment application describes how funds were handled, while notice of error is the borrower’s complaint when that handling appears wrong.

It also differs from Qualified Written Request. A QWR is a defined RESPA category, not merely an obsolete name. A QWR that asserts a servicing error is treated as an NOE, and the same writing may also request information.

It differs from a general complaint because the NOE procedure requires an identifiable written assertion about mortgage servicing. A complaint can express dissatisfaction without identifying a covered error or triggering the same formal response path.

Knowledge Check

  1. Is a notice of error the same thing as a regular mortgage statement? No. It is a borrower notice that asks the servicer to review and correct an error.
  2. Does an origination or underwriting dispute automatically qualify as a servicing NOE? No. The Regulation X error-resolution procedure generally concerns administration of the mortgage after closing.
  3. Can one letter contain both an NOE and an RFI? Yes. The servicer evaluates the substance of each assertion and request, not merely the letter’s heading.
