Chambers USA 2027 Adds New Sections, Expands No‑Referee List

As we approach the start of the Chambers USA 2027 research cycle, Chambers has released two important updates that may affect submission strategy this year: (1) additional Nationwide sections that will not accept referees, and (2) a significant expansion of new submission areas for the 2027 guide. Chambers says research for the guide will begin in August 2026.

The most notable change on the referee side is that USA – Nationwide Litigation: General Commercial has now been added to the list of Nationwide sections for which Chambers will not contact referees. Chambers states that, for these sections, it will instead rely on feedback gathered through relevant state-based research.

On the submissions side, Chambers has introduced 32 new submission areas for Chambers USA 2027. These consist of 27 state-level categories across 20 states and 5 new Nationwide categories. Notably, three of these new sections begin research in July, making them the earliest Chambers USA deadlines this cycle and requiring immediate attention from firms with relevant practices.

Practical implications

For firms active in any of the new categories, this is a good time to assess whether work previously submitted under broader headings may now be better presented in a more targeted section. That is especially true in areas such as product liability, insurance, litigation specialisms, national security, and digital infrastructure, where Chambers appears to be drawing finer distinctions in its coverage.

For firms with strong Nationwide practices, the referee update reinforces the importance of a joined-up national/state submission strategy. Where Chambers is not taking separate referees for a Nationwide table, firms should ensure their state-level submissions are supported by the right clients and the right matters to tell a compelling broader story.

The most immediate deadlines are the three 16 July 2026 sections: California Media & Entertainment: Music, New Jersey Technology, and Texas Water Law. Firms with credible experience in those areas should move quickly if they want to participate in the first wave of research.
