Subpoena volumes from a recent Wolters Kluwer Financial & Corporate Compliance analysis hit 498,000 in 2025, increasing every year since a brief dip in 2020. Growth has been consistent (13% in 2023, 10% in 2024, 8% in 2025) and the composition of that growth is what makes it harder to manage than the headline number suggests.
Insurance-related subpoenas increased 65% between 2019 and 2025. Four states (California, Florida, Georgia and Texas) account for 80% of that activity. California saw a 54% increase in total subpoena volumes over the same period, driven by coverage disputes, surplus line insurer practices and new privacy compliance rules. Florida became the most active subpoena market in the country as regulatory investigations into hurricane claim denials accelerated and lawsuits piled up before recent tort reform measures took effect.
These numbers represent filings arriving faster, across more jurisdictions, with more complicated underlying disputes than legal operations teams have historically handled.
Growing complexity, not volume alone
Subpoena management has always been labor-intensive. A document arrives; someone reads it, identifies the relevant entity, determines the jurisdiction, assesses urgency and routes it. That process worked when the underlying disputes were more predictable and the jurisdictional exposure was narrower.
Insurance disputes today involve overlapping policies, contested coverage questions and multiple jurisdictions on a single filing. A subpoena related to a hurricane claim denial in Florida may implicate reinsurance agreements governed by New York law, surplus line policies issued in another state and privacy requirements specific to the claimant’s location. Meanwhile, as federal enforcement activity declines, state-level regulators and private litigants are generating more subpoena activity with less consistency in what gets required from one jurisdiction to the next.
The average subpoena now carries more variables, more stakeholders and a quicker turnaround for response. When every document requires cross-referencing entity records, jurisdictional rules and contractual obligations, manual triage breaks down well before the team does.
