Notice of Error: Mortgage Servicer Duties and RESPA Remedies

A notice of error to a mortgage servicer is a written letter that forces the company managing your loan to investigate and correct a specific mistake on your account. Under federal law, once the servicer receives a properly addressed letter, it must acknowledge it within five business days and send a written response within 30 business days.¹ The process comes from Regulation X, which implements the Real Estate Settlement Procedures Act (RESPA), and it effectively puts the burden on the servicer to prove the account is right once you’ve raised the issue.

What a Notice of Error Can Fix

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

The most common complaints involve payments and fees. Covered errors include failing to apply a payment correctly to principal, interest, or escrow, and failing to credit a payment on the date it was actually received. If the servicer charged a fee it had no reasonable basis to impose, that is a covered error too. The CFPB’s official commentary points to examples like a late fee on a payment that wasn’t late, a charge for a service that was never performed, or a property management fee when you weren’t in a delinquency that justified it.²

Escrow failures count as well. If the servicer misses a property tax payment, lets your hazard insurance lapse, or fails to refund an escrow surplus when required, you can dispute it. An inaccurate payoff balance in response to your request is a covered error, and so is a botched transfer of account information when your loan moves to a new servicer.¹

Foreclosure and loss mitigation problems are also within scope. Inaccurate information about loss mitigation options, starting foreclosure proceedings before federal rules allow, or moving for a foreclosure sale while a complete loss mitigation application is pending all qualify.¹ Force-placed insurance is another frequent fight: if you had continuous coverage and the servicer charged you for its own policy anyway, or skipped the required advance notices before imposing the charge, you have grounds for a notice.³

The regulation closes with a catch-all for “any other error relating to the servicing of a borrower’s mortgage loan.” You are not limited to the categories named above. If something has gone wrong in the handling of your account, the notice process is available.⁴

What to Put in the Letter

The regulation sets a low bar for what triggers the servicer’s duties. Your notice must be in writing and must include your name, information the servicer can use to identify your loan account (your account number), and a description of the error you believe occurred.¹

That is the legal minimum. In practice, specificity is what gets a result. Identify the 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 anything that backs up your claim: bank statements showing the payment cleared, canceled checks, insurance declaration pages, screenshots of online payment confirmations, or earlier correspondence with the servicer. Keep the originals; send copies only.

Where to Send It

This is where most notices die. Your letter must go to the specific address the servicer has designated for receiving error disputes. That is almost never the same address where you mail your monthly payment. Servicers are required to list the designated address on your monthly statements and on their website.¹ A notice sent to the payment processing center or a general corporate address does not trigger the servicer’s legal obligations.

Send it by certified mail with return receipt requested. The regulation does not require certified mail, but if the servicer later claims it never got the letter, the green card is your proof of what arrived and when.

What the Servicer Must Do Next

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. It can extend that deadline by 15 additional business days if it notifies you of the delay and explains why before the original 30 days expire. The extension is not available for errors involving payoff balance requests or certain foreclosure violations.⁴

The response 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.⁴

The servicer cannot charge you a fee or demand a payment as a condition of responding. The investigation is free, and it can’t be held hostage to a past-due balance.⁴

If your notice disputes a specific payment, the servicer also cannot report negative information about that payment to credit bureaus for 60 days after receiving your notice. The protection applies to the disputed payment, not to your whole account.⁴

When the Servicer Can Refuse to Investigate

Three situations let a servicer decline to investigate. Knowing them upfront keeps your notice out of the rejection pile.

Duplicate notices. If you already submitted a notice about the same error and the servicer completed its investigation, repeating it won’t restart the clock, unless you have new evidence the servicer didn’t review the first time.
Overbroad or vague notices. If the servicer cannot reasonably figure out what specific error you are claiming, it can treat the notice as overbroad. If it can identify a valid error claim within an otherwise unclear letter, it still has to investigate that part.
Untimely notices. If you send a notice more than one year after the loan was transferred away from that servicer, or more than one year after the loan was paid off or discharged, the servicer has no obligation to investigate.

Even when one of these applies, the servicer still has to tell you in writing that it is declining and why.⁴

When a Request for Information Is the Better First Step

Sometimes you know something is wrong but don’t have enough detail to describe the error. In that case, a Request for Information under a separate section of Regulation X is often the better opening move. The format is similar: a written request with your name, account-identifying information, and a description of what records you want. The servicer has the same five-business-day acknowledgment and 30-business-day response deadlines, with the same 15-day extension option.⁵

A common sequence is to request your escrow or payment history first, review it, then send a Notice of Error once you can point to the specific mistake. Both can be combined in a single letter if you already know the error and also want supporting records.

What You Can Do If the Servicer Ignores You

A servicer that misses the deadlines, sends an inadequate response, or ignores your letter is violating federal law. Two routes are available.

File a Complaint With the CFPB

The Consumer Financial Protection Bureau takes complaints about mortgage servicers at consumerfinance.gov/complaint. The CFPB forwards the complaint to the servicer, which generally must respond within 15 days. A CFPB complaint will not win you money by itself, but it creates regulatory pressure and a documented record if you later go to court.⁶

Sue Under RESPA

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

Class actions are available when a servicer’s failures affect many borrowers. Statutory damages in a class action can reach up to $2,000 per class member, capped at the lesser of $1,000,000 or one percent of the servicer’s net worth.⁷

The fee-shifting provision matters more than the damage caps suggest. Because RESPA shifts fees to the servicer, attorneys will often take meritorious cases on contingency even when the actual damages are modest. That is what makes the notice process enforceable for ordinary borrowers.

Practical Habits That Help

Keep a log of every communication with your servicer, including phone calls. Note the date, the representative’s name, and what was said. If you call before sending a notice, ask for a call reference number. These details become evidence if the dispute goes further.

Stick to one error per letter when you can. A letter raising five issues at once is more likely to be flagged as overbroad, and it gives the servicer room to address the easy items while sidestepping the important one. Separate notices for separate issues are usually stronger.

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

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