Before a lender can start a residential foreclosure lawsuit in New York, it must send the borrower a specific statutory warning letter at least ninety days in advance. That letter is governed by Real Property Actions and Proceedings Law (RPAPL) § 1304, and it is one of the most heavily litigated provisions in New York foreclosure practice. The reason is simple: New York courts require strict compliance with § 1304. A notice that is sent late, worded incorrectly, mailed the wrong way, or bundled with other material can defeat the entire foreclosure action, even where the borrower is undeniably in default.
This page explains what RPAPL 1304 actually requires, who is entitled to the notice, how lenders must prove compliance, and the specific defects borrowers can raise as defenses.
RPAPL § 1304(1) provides that with regard to a "home loan," at least ninety days before a lender, assignee, or mortgage loan servicer commences legal action against the borrower (including a mortgage foreclosure), it must give the borrower a written notice. The statute dictates nearly everything about that notice:
RPAPL § 1304(2) requires the notice to be sent both by registered or certified mail and by first-class mail, to the borrower's last known address and, if different, to the residence that is the subject of the mortgage. Notice is considered given as of the date it is mailed, not the date received. Sending by only one method, or to only one of the required addresses, is a fatal defect.
Under § 1304(4), only one 90-day notice needs to be sent in any twelve-month period to the same borrower for the same loan. If a foreclosure is dismissed and re-filed years later, however, courts frequently require a fresh notice because the original notice has gone stale and the default figures no longer reflect reality.
Section 1304 applies only to a "home loan" as defined in RPAPL § 1304(6)(a): a loan to a natural person, secured by a mortgage on residential real property in New York improved by a one-to-four family dwelling or a condominium unit, which the borrower uses or occupies (or intends to use or occupy) as his or her principal dwelling.
The statute also contains express carve-outs in § 1304(6)(b). The notice is not required where:
These exemptions generate their own litigation. Lenders bear the burden of proving an exemption applies; a bare allegation that the property is an investment property is not enough. Occupancy questions become especially complicated when the borrower has died before the action is commenced, a scenario with its own procedural rules, discussed in our guide to foreclosure of property owned by someone who died in New York City.
RPAPL § 1306 requires the lender or servicer to file an electronic statement with the Superintendent of Financial Services within three business days of mailing the § 1304 notice. Like the notice itself, the § 1306 filing is a condition precedent to a residential foreclosure action, and the complaint must be accompanied by proof of the filing. In CIT Bank N.A. v. Schiffman, 36 N.Y.3d 550 (2021), the Court of Appeals held that a § 1306 filing that lists only one borrower on a multi-borrower loan still satisfies the statute, but the failure to file at all, or to file on time, remains a viable defense.
Since Aurora Loan Services, LLC v. Weisblum, 85 A.D.3d 95 (2d Dept. 2011), New York courts have held that proper service of an RPAPL 1304 notice is a condition precedent to the foreclosure action, and that "strict compliance" (not substantial compliance) is required. Practical consequences:
The most common battleground is proof of mailing. In CIT Bank N.A. v. Schiffman, the Court of Appeals confirmed that a lender can establish the presumption that the notice was mailed in either of two ways:
To rebut the presumption, a borrower must show a material deviation from the office practice, one that calls into question whether the notice was actually mailed. A minor, non-material deviation is not enough. In practice, lender affidavits fail when the affiant works for a servicer but describes a prior servicer's mailing practices without personal knowledge, when the affidavit recites conclusions without describing the actual procedure, or when the exhibits (certified mail numbers, copies of the envelopes, mailing logs) do not match the notices attached.
For several years, courts dismissed foreclosures because the 90-day notice envelope also contained additional material, most commonly bankruptcy disclaimers or Fair Debt Collection Practices Act language. The Court of Appeals resolved the issue in Bank of America, N.A. v. Kessler, 39 N.Y.3d 317 (2023), holding that including accurate, non-misleading information that relates to the notice does not violate § 1304(2)'s separate-envelope requirement. Kessler significantly narrowed this defense, but it did not eliminate it: material that is false, misleading, or unrelated to the statutory purpose (or that obscures or contradicts the required warnings) can still render the notice defective. Pre-Kessler dismissals also remain relevant to statute-of-limitations calculations in re-filed actions.
A servicer mails the § 1304 notice on March 1 and files the foreclosure summons and complaint on May 25, day 85. Even though the borrower is eleven months in default, the action was commenced before the ninety-day period elapsed. The complaint is subject to dismissal, and the lender must wait out a fresh notice period before re-filing.
A lender's affidavit attaches a certified mail receipt for the notice sent to the mortgaged premises, but the record contains no evidence of a first-class mailing and nothing sent to the borrower's separate last known address on file (the borrower had moved and updated the servicer). Under § 1304(2), the mailing is defective in two respects, and summary judgment for the lender should be denied.
The notice states the borrower is 120 days in default and must pay $9,400 to cure, but the servicer's own payment history shows the loan was 240 days past due with arrears exceeding $18,000 at mailing. Courts have found materially inaccurate default and cure figures inconsistent with strict compliance, because the statute's purpose is to give the borrower accurate information needed to avoid foreclosure.
An RPAPL 1304 defense rarely eliminates the debt, but it buys leverage and time, often the critical window needed to negotiate a loan modification, pursue settlement conference relief under CPLR 3408, or refinance. For the broader strategy, see our overview of how to stop a foreclosure in New York.
If you are a homeowner served with a New York foreclosure complaint, we audit the lender's RPAPL 1304 and 1306 compliance line by line (the mailing proof, the notice contents, the addresses, and the timing) and assert every viable defect in your answer and at summary judgment. If you are a lender, servicer, or note purchaser, we review your notice package before filing, cure defects before they become dismissals, and defend strict-compliance challenges with admissible proof of mailing that satisfies the Schiffman standard.
