Who is actually suing
Mortgage loans are sold and transferred often, and the company that files the case is not always the one that made the loan. A recurring question in New York foreclosure cases is whether the plaintiff had the right to sue when it filed, which usually depends on who held the note at that moment. Gaps in endorsements, missing assignments, or a note that surfaces late can make that question worth pressing. This is an argument about paperwork and proof rather than fairness, and courts treat it that way. It does not erase the debt, but it can end or delay a particular case.
Notices, timing, and lender conduct
New York requires lenders to send certain notices to homeowners before filing on many home loans, and the content and delivery of those notices are frequently contested. Timing is another source of defenses: a loan accelerated long ago may raise limitations questions, an area the state legislature reshaped recently in ways the state's highest court has applied to older loans. The lender's own conduct can also matter, including how it handled a modification application and whether it negotiated in good faith at the settlement conferences held in many residential cases. Each of these depends heavily on dates and documents, so a reliable timeline is often the most useful thing a homeowner can bring. Keep every envelope, notice, statement, and letter from the servicer, along with any record of calls you already have.
Raising defenses before they slip away
Many defenses must be raised in the answer or an early motion, and a homeowner who does not respond to the summons can lose the chance to raise them at all. New York gives homeowners in residential cases some protection on this point, but relying on it is a poor plan. Missing the response window can also lead to a default, and undoing one generally takes both a reasonable excuse and a defense worth hearing. In a first review we read the complaint, check which notices were sent, build the loan's timeline, and talk about whether your aim is to keep the house, buy time for a sale, or reach a negotiated exit. Foreclosure defenses are most useful when they support a goal you have chosen.
