What 4 New Square does

4 New Square Chambers is one of the leading commercial barristers' sets in England and Wales, headquartered at 4 New Square, Lincoln's Inn, London (with reception at 2 New Square). The chambers operates as a collective of self-employed barristers — approximately 40+ King's Counsel (Silks) and 75+ junior counsel — supported by a 22+-person clerking and administration team led by Senior Clerk & CEO Lizzy Stewart, plus an annual pupillage intake of 4 tenants funded at £90,000 per pupil for 2026. Members are individually regulated by the Bar Standards Board and covered by the Bar Mutual Indemnity Fund.

The chambers delivers advocacy and advisory services across 24+ practice areas, with centres of gravity in commercial litigation, arbitration, professional negligence, construction and energy, civil fraud, insurance and reinsurance, banking, company and insolvency, regulatory and disciplinary, and a newer AI, Digital Assets & Technology practice. Service delivery is enabled by conventional legal-practice digital infrastructure (website, Portfolio Builder, lexlinks CRM) and supported by ISO 27001 and Cyber Essentials certifications; the AI Hub is a curated content and guidance platform rather than a model-based tool.

Commercially, 4 New Square earns through professional fees — typically hourly rates for advisory and drafting work, and brief fees plus daily refreshers for advocacy, with fixed/capped fees and occasional contingency arrangements also available. The GTM motion is sales-led via the clerking team, which acts as the central point of contact for instructions from UK solicitors, foreign lawyers, top international and boutique litigation firms, and — via the Public Access Scheme — direct clients. Marketing is anchored on Legal 500 and Chambers & Partners rankings, content (articles, podcasts, videos, the AI Hub), and a flagship annual Professional Liability and Regulatory Conference at the Royal College of Surgeons, with awards recognition including Chambers of the Year at the Legal Business Awards 2025 and 21 nominations at the Legal 500 Bar Awards 2026.
