How derivatives disputes usually start
Most over-the-counter derivatives are documented under an ISDA Master Agreement with a schedule and often a credit support annex, and many of those are governed by New York or English law. Disputes commonly arise over whether a termination event actually occurred, how a close-out amount was calculated, or whether collateral was properly demanded and valued. Some cases involve allegations that a dealer misrepresented the risk of a product to a less sophisticated client, which raises questions about the relationship and the documents the client signed. Exchange-traded futures and options disputes often run through different channels, including exchange rules and arbitration. If you were searching for a shareholder derivative action, which is a suit a shareholder brings on behalf of a company, usually against its own directors or officers, that is a different kind of case.
Records that decide the numbers
Gather the master agreement, the schedule, any credit support documents, trade confirmations, and every notice exchanged, including the exact time and method of delivery, since notice provisions are often strictly read. Valuation is frequently the core of the dispute, so keep the market data, dealer quotes, and internal pricing records used at the time. Recorded calls and chat messages with the trading desk can matter as much as the paper. If a counterparty is in bankruptcy or another insolvency process, special rules for financial contracts may apply that differ from ordinary contract claims. Preserve all of this before any routine data deletion cycle runs.
Choosing the forum and the timing
Many master agreements choose courts in New York or London, while some trades carry arbitration clauses, and the choice affects discovery and speed. A derivatives action can also overlap with regulatory issues before the CFTC or the SEC, depending on whether the product is a swap or a security-based swap. In a first discussion we look at the documents, the sequence of notices, and the valuation methods each side used. We then assess whether there is room to negotiate a revised close-out figure or whether the matter needs to go to court. Because positions and collateral may still be moving, timing decisions are often made quickly.
