Notice of Error: How to Write, Send, and Enforce One

If your mortgage servicer has made a mistake on your loan account, a Notice of Error is the written letter that forces it to investigate and fix the problem. Federal law gives the servicer five business days to acknowledge your letter and 30 business days to respond, and the process is governed by Regulation X under the Real Estate Settlement Procedures Act. Once you’ve raised the issue properly, the burden of proving the account is correct shifts onto the servicer.¹

Errors You Can Raise This Way

The Notice of Error process covers mistakes in how your loan is being serviced. It does not cover problems with how the loan was originated or approved.²

Payments and Fees

Payment mistakes are the most common disputes. Covered errors include failing to apply your payment correctly to principal, interest, or escrow, and failing to credit a payment on the date it was actually received. Charging a fee the servicer had no reasonable basis to impose is also covered. The CFPB’s official commentary points to concrete examples: a late fee on a payment that wasn’t late, a charge for a service that was never performed, or a property management fee assessed when you weren’t in a delinquency that justified it.²

Escrow, Payoff, and Loan Transfers

Your servicer is responsible for paying property taxes and insurance premiums from escrow on time. Missing a tax payment or letting an insurance policy lapse is a covered error, and so is failing to refund an escrow surplus when required. Providing an inaccurate payoff balance is also disputable.¹ When a loan is transferred to a new servicer, the old servicer must pass along accurate account information, and failing to do so is a covered error you can raise with the servicer that made the mistake.³

Foreclosure and Loss Mitigation

Inaccurate information about loss mitigation options is a covered error, as is starting foreclosure proceedings in violation of federal rules, including moving for a foreclosure sale while a complete loss mitigation application is pending.¹

Force-Placed Insurance

Force-placed insurance is one of the most expensive servicing mistakes borrowers encounter. Your servicer can only charge you for force-placed hazard insurance if it has a reasonable basis to believe you’ve let your own coverage lapse, and it must follow a strict two-notice process before imposing the charge. The first notice must go out at least 45 days before any charge is assessed, and a second notice must follow. If you’ve provided proof of continuous coverage and the servicer charged you anyway, or if it skipped the required notices, you have grounds for a Notice of Error. A copy of your declaration page, insurance certificate, or similar written confirmation should be enough to demonstrate coverage was in place.⁴

The Catch-All

The regulation includes a broad final category: “any other error relating to the servicing of a borrower’s mortgage loan.” You are not limited to the listed error types. If something has gone wrong in the management of your account and it doesn’t fit a named category, you can still use the process to force an investigation.³

How to Write the Letter

The regulation sets a low legal bar for triggering the servicer’s duties, but the more specific your letter, the harder it is for the servicer to brush aside.

Your notice must be in writing and include three things: your name, information the servicer can use to identify your loan account (typically the account number), and a description of the error you believe occurred.¹ That is the legal minimum. In practice, go further. Identify the specific date, dollar amount, and nature of the problem. “My $1,500 payment made on March 3 was not credited to my account” is far more effective than “my balance seems wrong.”

Attach copies of any evidence supporting your claim: bank statements showing the payment cleared, canceled checks, insurance declaration pages, screenshots of online payment confirmations, or prior correspondence. Keep the originals and send copies only.

Stick to one error per letter when you can. A letter raising five different issues at once is more likely to be flagged as overbroad, and it gives the servicer room to answer only the easy items while sidestepping the important one. Multiple issues can go in separate notices.

Where to Send It

This is where most people trip up. Your notice must go to the specific address your servicer has designated for receiving error disputes. That is almost never the address where you mail your monthly payment. Servicers are required to list the designated address on your monthly statements and on their website.¹ Sent to a payment processing center or a general corporate address, the notice carries no legal weight.

Send it by certified mail with return receipt requested. Certified mail is not required by the regulation, but if you ever need to prove the servicer received your notice and when, the green card is your evidence. Without proof of delivery, a servicer can claim it never received the letter and you are back to square one.

What the Servicer Must Do and When

Once your properly addressed notice arrives, a clock starts. The servicer must acknowledge receipt in writing within five business days, not counting weekends or federal holidays.¹

From there, the servicer has 30 business days to investigate and send you a written response. The deadline can be extended by 15 additional business days if the servicer notifies you of the delay and explains why before the original 30 days expire. That extension is not available for errors involving a payoff balance request or certain foreclosure violations.³

The response itself must take one of two forms. If the servicer agrees an error occurred, it must correct the error and send you written confirmation of the correction along with the effective date. If the servicer concludes no error occurred, it must explain why, describe the basis for that determination, and tell you that you have the right to request copies of the documents it relied on. If the investigation turns up a different error than the one you reported, the servicer must fix that one too and notify you.³

The servicer cannot charge you a fee or demand a payment as a condition of responding to your notice. The investigation is free, and the servicer can’t hold it hostage to a past-due balance.³

If your notice disputes a specific payment, the servicer cannot report negative information about that payment to credit bureaus for 60 days after receiving your notice. The protection applies to the payment you’re disputing, not to your entire account.³

When a Servicer Can Refuse to Investigate

The process has limits. A servicer can decline to investigate in three situations:³

You already submitted a notice about the same error and the servicer completed its investigation. New evidence the servicer didn’t review the first time is the exception.
The letter is so vague the servicer can’t reasonably identify what error you’re claiming. If any valid claim can be identified inside an otherwise vague letter, though, the servicer still must investigate that portion.
You sent the notice more than one year after the loan was transferred away from that servicer or more than one year after the loan was discharged.

Being specific, being timely, and raising genuinely new issues keeps your notice out of these rejection categories.

When You Don’t Yet Know the Error

Sometimes you sense something is wrong but can’t describe the specific mistake. In that case, a Request for Information under a separate section of Regulation X may be the better first step. You submit a written request that includes your name, account-identifying information, and a description of what information you want. The servicer must acknowledge receipt within five business days and respond within 30 business days, with the same 15-day extension option.⁵

The practical strategy is to request records first, then follow up with a Notice of Error once you can point to the specific problem. If you think your escrow account was miscalculated but don’t have the payment history to pinpoint the mistake, ask for the full escrow history. Once you can identify the error, send the Notice of Error. Both requests can also be combined in a single letter.

If the Servicer Ignores You

A servicer that misses the deadlines, sends an inadequate response, or ignores your notice is violating federal law, and you have two main options.

File a CFPB Complaint

The Consumer Financial Protection Bureau accepts complaints about mortgage servicers at consumerfinance.gov/complaint. After you submit, the CFPB forwards the complaint to the servicer, which generally must respond within 15 days. The CFPB publishes complaint data in a public database and tracks patterns of servicer misconduct. A CFPB complaint doesn’t produce money damages on its own, but it applies regulatory pressure and creates a documented record if you later pursue legal action.⁶

Sue Under RESPA

RESPA gives you the right to sue a servicer that violates the error resolution requirements. In an individual lawsuit, you can recover actual damages: late fees you shouldn’t have paid, credit damage, costs from a missed tax payment the servicer should have made. If the court finds the servicer engaged in a pattern or practice of noncompliance, it can award up to $2,000 in additional statutory damages on top of your actual losses. The court can also order the servicer to pay your attorney’s fees and litigation costs.⁷

The attorney’s fees provision matters more than the damage cap suggests. Because RESPA shifts fees to the servicer when the borrower wins, attorneys will often take meritorious cases on contingency even when actual damages are modest. That is the mechanism that makes the Notice of Error process enforceable for ordinary borrowers, not just those with large claims.

Habits That Improve Your Odds

Keep a log of every communication with your servicer, including phone calls. Write down the date, the representative’s name, and what was said. If you call before sending a Notice of Error, note the call reference number. These details become evidence if the dispute escalates.

If the servicer denies your claim, request the documents it relied on. You have the right to see the basis for the determination, and reviewing those records often reveals additional errors or gives you the ammunition for a follow-up notice with new evidence the servicer must investigate fresh.

Don’t wait. The one-year deadline after a loan transfer or discharge is a hard cutoff, memories fade, and records get harder to obtain over time. When something looks wrong on your statement, start the process that month.
