Banking and finance litigation is unusually document-driven: the promissory note, loan agreement, security instrument, and guaranty define almost every right at issue before the dispute ever starts, and most cases turn on how those instruments interact with statutory frameworks layered on top of them, from the Uniform Commercial Code governing secured transactions to state foreclosure procedure and, for consumer-facing loans, federal disclosure regimes. Because these relationships are heavily papered, straightforward breach claims (did the borrower default, was notice properly given, was a cure period honored) sit alongside a second category of dispute that turns on how the lender exercised the discretion the documents gave it — accelerating a loan, refusing to fund a draw, or reinterpreting a covenant in a way the borrower argues was never the deal.

That second category, often labeled lender liability, is what makes these cases strategically different from an ordinary contract dispute. A lender's discretion is rarely unlimited even when the documents appear to say so, because courts read an implied covenant of good faith and fair dealing into the exercise of that discretion, and a lender that calls a performing loan or manufactures a technical default to reposition its risk can face liability well beyond the face amount at issue. Cross-collateralization and guarantor provisions mean a single default can cascade across multiple facilities and multiple obligors at once, which raises the stakes of an early litigation misstep and makes banks unusually protective of the precedent any individual case might set across their broader loan portfolio.

The default declaration is the fulcrum: whichever side controls the narrative of why the loan went into default — genuine borrower nonperformance versus a lender repositioning its risk — sets the tone for everything downstream, because a finding that the lender manufactured or opportunistically declared a technical default converts a routine collection matter into an institutional bad-faith case with reputational exposure the bank wants to avoid at almost any settlement cost. Guarantor and cross-collateralization provisions add pressure by exposing parties beyond the primary borrower, which broadens the group of stakeholders with an incentive to settle early rather than litigate the underlying covenant dispute to judgment.
