Why Does Due Diligence Litigation Matter to Corporations?

The most contested representations typically involve financial condition, compliance with law, customer contracts, intellectual property ownership, and the absence of undisclosed liabilities. Sellers often argue that certain facts were visible during the pre-closing investigation or that the corporation assumed the risk of discovery by accepting an as-is or with full knowledge carve-out in the purchase agreement. Courts in New York regularly examine whether the corporation's own pre-closing due diligence was reasonably thorough, because if a corporation failed to ask the right questions or inspect obvious records, courts may limit recovery even if the seller's silence was misleading.

Survival periods are contractual deadlines, often ranging from 12 to 24 months after closing, during which a corporation may bring a claim for breach of representation. Once the period expires, most representations disappear and the corporation loses the right to sue, regardless of when the breach was discovered. A corporation that discovers a breach one week before the survival period ends must file suit or lose the claim entirely; in practice, this timing pressure creates significant risk if the corporation's internal systems do not flag approaching deadlines or if the corporation is still integrating operations and has not yet completed a full audit of the acquired business.

A materiality threshold (e.g., no single item exceeding $500,000 or aggregate items exceeding $2 million) requires the corporation to prove that the undisclosed fact fell outside the threshold before recovery is available. A materiality scrape removes the seller's materiality qualifiers from the representation at the time of indemnification, effectively allowing the corporation to aggregate multiple small breaches to meet a dollar floor. Courts treat these provisions as contractual allocations of risk, and the corporation bears the burden of proving the aggregate amount with precision; rough estimates or projected losses often fail to satisfy this burden.

New York courts distinguish between active fraud (the seller knowingly misrepresented a fact) and passive concealment (the seller remained silent about a material fact despite a duty to disclose). A corporation asserting fraud must clear a higher evidentiary bar and prove scienter (intent to deceive), whereas a breach of representation claim requires only that the representation be false, regardless of the seller's state of mind. Courts may also consider whether the corporation's pre-closing investigation uncovered red flags that should have prompted further questioning; if the corporation ignored warning signs, courts may find the corporation assumed the risk of non-disclosure. In Brooklyn Federal Court and other high-volume commercial dockets, delayed verified documentation of loss (such as a loss affidavit filed weeks after discovery) can complicate the corporation's ability to establish the precise timing and causation of harm.

A corporation that maintains detailed due diligence files, including written responses to information requests, management presentations, audit reports, and notes of meetings with the seller's representatives, can demonstrate that the seller either affirmatively misrepresented facts or deliberately withheld information despite being asked. Courts view contemporaneous documentation as more reliable than post-hoc recollection, especially when the corporation can show that it specifically requested information about the area later found to be false. The corporation should also preserve communications showing that the seller declined to provide certain records or gave evasive responses, because silence in response to a direct question can constitute actionable concealment under New York law.

A corporation should compile a chronology showing when the breach was discovered, what investigation was undertaken to confirm the breach, and how the breach caused specific quantifiable harm. The corporation should also preserve all pre-closing due diligence materials, communications with the seller, and post-closing integration records that reveal the extent of the undisclosed problem. Additionally, a corporation should document any attempts to mitigate loss (e.g., remedial actions taken to address the breach) and any communications with the seller regarding the breach, because the seller's response may either confirm knowledge or reveal efforts to conceal. A corporation that delays in formalizing its loss calculation or fails to document the causal link between the breach and the loss risks losing credibility with a court and may find its recovery reduced or eliminated.

A corporation should also consider whether the breach implicates regulatory compliance or advertising litigation exposure (e.g., if the seller misrepresented marketing claims or regulatory status), because such issues may trigger separate enforcement actions that can either support or complicate the corporation's indemnification claim. Finally, a corporation should evaluate whether the purchase agreement permits informal resolution through the indemnification procedures outlined in the deal documents before commencing formal litigation, as many agreements require notice and negotiation periods that, if skipped, may waive the corporation's right to recover.
