Why You Should Never Agree to a Loan That Waives Your Defenses

One of the most dangerous provisions buried in many commercial loans and personal guarantees is a clause waiving all defenses, counterclaims, or offsets. These clauses are often described as “standard,” but in reality they are designed to strip a borrower or guarantor of meaningful legal protection before anything goes wrong. Once signed, they can turn even blatant lender misconduct into an unenforceable complaint.

In plain terms, a waiver of defenses means the borrower agrees to pay the debt regardless of what the lender does. Even if the lender breaches the agreement, cuts off funding, manipulates a foreclosure or auction process, or otherwise acts unfairly, the borrower may be contractually barred from raising those facts in court. The loan becomes enforceable almost on autopilot.

New York courts have repeatedly enforced these clauses, particularly in commercial loans and guarantees. The default rule is unforgiving: an “absolute and unconditional” waiver generally bars defenses and counterclaims. That is exactly why lenders insist on them. They reduce litigation risk, accelerate enforcement, and shift virtually all downside risk to the borrower or guarantor.

The danger is illustrated vividly in MCC Funding LLC v. Diamond Point Enterprises, LLC. (Sup. Ct. Kings County 2012). There, a developer alleged that its construction lender stopped funding almost immediately, leaving a half‑demolished property and catastrophic losses. When the lender later sought foreclosure, it argued that broad waiver language in the loan documents barred all defenses and counterclaims. Although the court ultimately allowed the borrower’s fraud claims to proceed, it made clear that waivers of defenses are usually enforceable and will only fail when a borrower can plead detailed, specific fraud. Absent those allegations, the waiver would have wiped out the borrower’s case entirely.

The risks are even starker for guarantors, as shown in In re Futterman (SDNY Bankruptcy 2019) a federal bankruptcy decision applying New York law. There, the guarantor signed an “irrevocable, absolute and unconditional” guaranty that waived all defenses, offsets, and counterclaims. After the lender acquired the property through a credit bid and asserted a massive deficiency claim, the guarantor tried to challenge the valuation and the auction process. The court explained that, as a general matter, such waivers are enforceable and are meant to prevent exactly that kind of challenge. Only allegations of post‑guaranty fraud, collusion, or exploitative overreaching could potentially defeat the waiver.

Graciously, the Futterman court held that public policy will not allow a lender to use a waiver to shield itself from its own future fraud—which saved the day for the guarantor. But everything else was held to be waived. Complaints about unfairness, bad faith negotiations, cooperation failures, or mere inadequacy of price will not be enough. The odds are stacked heavily against the borrower or guarantor once the waiver is in place.

What makes these clauses particularly hazardous is how often they reappear later in the relationship. Even borrowers who avoided waivers in the original loan are frequently asked to sign them in extensions, forbearance agreements, or modifications after a default. By that point, the lender may already have engaged in questionable conduct, and the new waiver can quietly erase those claims forever.

The lesson from MCC Funding and In re Futterman is not that courts will always save borrowers from unfair waivers—they usually won’t. Courts enforce these provisions precisely because sophisticated parties are presumed to understand what they signed. Fighting back requires expensive litigation and proof of serious misconduct, and even then success is uncertain.

If a lender insists on a waiver of defenses, the message is simple: you are being asked to trust that lender with unchecked power. In most cases, that is not a risk worth taking.
