Mortgage notice-of-error acknowledgment and response deadlines

A borrower who believes a mortgage servicer made an error can send a written notice of error under Regulation X. The notice must include the borrower's name, information that lets the servicer identify the mortgage account, and a description of the error. The servicer's timelines depend on what the alleged error concerns, so distinguish the acknowledgment deadline from the deadline to investigate and respond.

The general acknowledgment deadline

Within five days after receiving a notice of error, excluding legal public holidays, Saturdays, and Sundays, the servicer generally must send a written acknowledgment. This confirms receipt; it is not the final decision on whether an error occurred. Acknowledgment and investigation are separate steps.

The investigation and response deadlines

For most asserted servicing errors, the servicer must correct the error and notify the borrower, or conduct a reasonable investigation and explain why it determined no error occurred, within 30 days after receiving the notice, excluding legal public holidays, Saturdays, and Sundays. If the servicer identifies a different or additional error during its investigation, it must correct that error as well and describe the action taken.

The servicer may extend the general 30-day period by an additional 15 days for errors governed by the ordinary deadline if it sends written notice of the extension and the reason before the initial 30-day period ends. The extension is not available for specified categories with separate short deadlines, including certain payoff-statement errors and the identified foreclosure-process errors.

What makes a qualifying notice

The borrower must send a written communication that identifies the borrower and account and explains the suspected servicing error. A servicer may designate an address for notices of error and must tell borrowers to use it. Sending the notice to a general payment address can create avoidable delay if the servicer has properly designated a separate address. A notice written on a payment coupon or other payment form supplied by the servicer need not be treated as a formal notice of error.

Examples of covered servicing errors

• Failure to accept a conforming payment or properly credit a payment.
• An incorrect fee, escrow, or account balance in the servicing records.
• Failure to provide accurate information about loss-mitigation options or foreclosure when required.
• Failure to transfer servicing information accurately and on time.
• Certain violations in the first foreclosure notice or filing, judgment, order of sale, or foreclosure sale.
• Other errors relating to servicing the mortgage loan.

What the servicer's response must say

If the servicer corrects an error, its written response must describe the correction, its effective date, and contact information. If it concludes that no error occurred, it must state that determination and its reasons, explain the borrower's right to request documents relied on in reaching the decision, and provide instructions for requesting them. A servicer cannot require the borrower to pay a disputed amount as a condition of investigating or responding, although the borrower's underlying contractual payment obligations remain in place.

A timeline example

A borrower sends a written notice alleging that a payment was posted to the wrong month. The servicer receives it on a Monday that is not a holiday. The five-day acknowledgment clock excludes Saturdays, Sundays, and legal public holidays. The servicer then generally has 30 counted days to correct the error or provide a reasoned investigation response, unless a specific shorter rule applies. If it needs the additional 15 days, it must notify the borrower in writing before the first 30-day period expires.

For the SAFE exam, keep three numbers attached to their proper step: five days to acknowledge; usually 30 days to investigate and respond; and a possible 15-day extension for most, but not all, errors. Payoff and foreclosure allegations have special timing rules. Always check the exact current regulation when applying the rule to a live dispute.

First verify it is a covered written notice

Regulation X §1024.35 applies to a written notice from the borrower that asserts an error, includes the borrower’s name, provides information that lets the servicer identify the mortgage account, and states the error believed to have occurred. A payment coupon or other servicer-supplied payment form need not be treated as a notice of error. A qualified written request that alleges a servicing error is covered.

When a servicer receives a qualifying notice, it generally must acknowledge it within five days, excluding Saturdays, Sundays, and legal public holidays. The servicer then must correct the error and notify the borrower, or conduct an investigation and provide the required written explanation within the applicable period.

General and special response clocks

The general investigation period is 30 days, excluding Saturdays, Sundays, and legal public holidays. For certain specified errors—such as an asserted failure to provide an accurate payoff balance—the regulation has a shorter seven-day period. Identify the error category before using the general deadline.

For errors subject to the general 30-day period, the servicer may extend by 15 days when it provides written notice of the extension and reasons before the original period expires. The extension is not available for every category; use the text of §1024.35(e)(3) and its exceptions. A servicing transfer or foreclosure schedule can also affect the operational response and should be escalated promptly.

Worked deadline example

Assume a servicer receives a covered notice on Monday and there are no intervening legal public holidays. Exclude the receipt day where the general counting convention requires, then count only weekdays for the five-day acknowledgment. The 30-day response clock uses the same exclusion of Saturdays, Sundays, and public holidays. A calendar system should calculate the deadline from receipt, not from when a staff member opens or routes the letter.

If a borrower submits a notice shortly before a foreclosure sale, route it immediately. Some alleged errors have specific protections and timing, and an internal queue cannot justify missing the regulatory deadline. Preserve the date received, account identification, alleged error, investigation steps, and response proof.

Differentiate a notice of error from information request

A request for servicing information is governed by §1024.36, while an asserted servicing error is governed by §1024.35. A letter can contain both; classify and respond to each part under the appropriate rule. Do not reject a notice because it lacks a preferred form if it contains the information required by the regulation.

The exam trap is memorizing “5 and 30” without the error category, exclusions, and extension conditions. State the initial acknowledgement, general investigation response, excluded days, shorter deadlines where applicable, and the written-notice requirement for a permitted extension.
