A data-driven view of litigation evidence trends in the United States

The CT Corporation Legal Records Demand Index examines subpoena activity across the United States to identify emerging patterns in litigation, investigations, and records requests.

Drawing on seven years of proprietary service of process data, the Index provides insight into how demand for third-party records — including healthcare, insurance, employment, banking, and business records — has evolved over time. The findings offer a unique perspective on trends in requests for third-party records associated with legal proceedings and other matters.

2026 key findings

Subpoena activity is growing faster than overall service of process activity

Between YTD June 2019 and YTD June 2026, subpoena volume increased 67%, outpacing growth in non-subpoena service of process activity, which increased 40% during the same period.

The findings point to a significant increase in requests for third-party records associated with legal proceedings and other matters. While the data does not identify the factors driving individual subpoenas, subpoena activity grew substantially faster than non-subpoena service of process activity throughout the period analyzed.

Pandemic and recovery trends

The data reveals differing impacts across record categories during and after the COVID-19 pandemic.

While categories such as employment, financial, and banking records experienced initial declines, healthcare, pharmacy, and insurance-related records continued increasing throughout much of the period analyzed. 

By YTD June 2026, every major subpoena category examined exceeded pre-pandemic levels.

Why this matters

The Index shows substantial growth in subpoena activity across multiple record categories and jurisdictions. While the data does not identify the factors driving individual requests, the findings provide a view into how demand for third-party records has changed over time. Organizations involved in receiving, managing, or responding to subpoenas may find these trends useful for understanding the evolving legal and compliance landscape.

About the findings

The Legal Records Demand Index reports observed subpoena activity trends within the analyzed data set. The findings identify changes in subpoena volume over time but do not determine the causes of those changes or the nature of the underlying legal matters.

Methodology

The CT Corporation Legal Records Demand Index analyzes subpoena activity managed through CT Corporation's service of process operations between YTD June 2019 and YTD June 2026. The analysis examines subpoena trends by record type and jurisdiction and compares subpoena activity with non-subpoena service of process volumes. Certain customer affiliations with atypical growth patterns or incomplete historical data were excluded to provide a more consistent longitudinal view.
