Deficiency Judgment After New York Foreclosure: Your Rights, Defenses, and the 90-Day Clock Under RPAPL 1371

When a foreclosure sale closes in New York, the auction price often falls short of what was owed on the mortgage. That gap — called the deficiency — can become a personal judgment against you if the lender moves quickly enough. The good news is that New York law under RPAPL § 1371 puts strict limits on that right: the lender has a short window to act, and the amount they can collect may be far less than the sale price suggests once fair market value is taken into account.

What a deficiency judgment is

If your home sold at foreclosure auction for $200,000 but you owed $280,000 on the mortgage, the deficiency is $80,000 (or less, once fair market value is applied — see below). Without a deficiency judgment, the lender has no personal claim against you for that amount — their remedy ends with the property. With a deficiency judgment, the lender becomes your general creditor and may pursue collection through wage garnishment, bank levies, or liens on other assets.

The 90-day window — RPAPL § 1371(2)

Under RPAPL § 1371(2), a foreclosing lender who wants a deficiency judgment must move the court within 90 days after the date the referee's deed is delivered to the purchaser at the foreclosure sale. This is a hard deadline. If the lender misses it, the right to seek a deficiency is permanently forfeited.

The clock starts on the delivery of the deed, not the auction date itself. Courts enforce this deadline strictly — a motion filed on day 91 is too late.

The fair-market-value protection

RPAPL § 1371 provides a critical protection: the deficiency is not simply the difference between your total debt and the foreclosure sale price. The court must determine the fair market value (FMV) of the property as of the sale date and use the higher of the actual sale price or the FMV when calculating what the lender received. The deficiency is then the debt minus that higher figure.

This matters enormously in practice. Foreclosure auctions routinely produce below-market bids. If your home's FMV was $250,000 but it sold for $150,000, the court uses $250,000 — not $150,000 — as the credit against your debt. On a $280,000 balance, that leaves only a $30,000 deficiency, not $130,000.

To make the FMV argument, you can submit an independent appraisal as evidence. The court may hold a hearing and weigh competing appraisals from both sides.

Common defenses and arguments

• Missed the 90-day deadline. If the lender did not move within 90 days of deed delivery, the motion must be denied. This is the clearest and most absolute bar.
• FMV equals or exceeds the total debt. If the fair market value at the time of sale was equal to or greater than what you owed, no deficiency can exist.
• Surplus proceeds. If the sale generated more than what was owed, there is no deficiency and the surplus belongs to junior lienholders or to you.
• Inflated payoff or fee claims. If the lender's stated debt amount includes improper charges or fees, challenging those figures can reduce or eliminate the apparent deficiency.

Deed-in-lieu and settlement waivers

A deed-in-lieu of foreclosure — where you voluntarily transfer the property to the lender to avoid a sale — often includes a written waiver of deficiency rights as part of the agreement. Similarly, short sales and certain forbearance or modification agreements may contain deficiency waivers. These waivers must be in writing and specific.

If you are negotiating a deed-in-lieu or settlement with a servicer, the deficiency waiver language is one of the most important terms to confirm in writing before you sign anything.

Tax and other consequences

A cancelled deficiency — whether waived by the lender or discharged in bankruptcy — may be treated as taxable income (the lender may file a 1099-C). Certain exclusions under federal tax law may apply, but this requires advice from a tax professional, not a self-help resource. If you are considering bankruptcy as a way to address a deficiency, that option also requires licensed legal counsel.
