What Costigan King does

Costigan King is a UK commercial law firm trading as Critchlow and Associates Limited, regulated by the Solicitors Regulation Authority (SRA Number: 628094), with offices in London (Quantum House, 22–24 Red Lion Court, EC4A 3EB) and New York (575 Fifth Avenue, Fl 14). The firm delivers legal services across six practice areas: Commercial Litigation, Construction & Energy, Corporate & Commercial, Dispute Resolution, Fintech & Blockchain Technology, and Gaming & Betting. It serves UK and international clients through direct engagement, with no intermediary or reseller channels. Its market positioning is "magic circle experience at alternative pricing," targeting commercial businesses, regulated operators (gambling, fintech, blockchain), and individuals requiring specialist legal advice in its core sectors.

The firm has no proprietary technology platform and operates as a people-led professional services practice. Senior lawyers include Arianne King (Solicitor Advocate, fintech/blockchain and gaming lead), Julian Critchlow (40+ years in construction disputes), Archie Berens (Corporate, formerly of Norton Rose Fulbright, returned to law in May 2024), and Amanda Lee (Solicitor-Advocate admitted to the NY Bar and US Supreme Court). Multi-jurisdictional service delivery relies on an established international lawyer network spanning the Isle of Man, Philippines, Curaçao, Cyprus, Africa, and the United States, with a local New York office providing direct US capability.

The revenue model is primarily hourly legal services, with paralegals at £200/hour, senior paralegals/trainees at £250/hour, and solicitors between £300 and £550/hour depending on case complexity and seniority. Fixed fees are offered for relatively clear matters such as debt recovery (in the order of £1,000 for straightforward matters; £3,000–£5,000 for more complex claims up to £100,000). Pricing tiers and SRA Transparency disclosures are publicly published. All fees exclude VAT; the firm does not enter into conditional fee or damages-based agreements. Client acquisition is sales-led via direct contact, partner referrals, website contact form, SEO-driven organic search, and thought leadership through the Insights blog. Named clients in the input data span enterprise (Toyota Plc), SMB (Eleven Hundred Agency), and startup (Renewable Infrastructure Network) segments, alongside technology/digital (Two Up Digital). The firm holds no patents or trademarks, has no funding history, and operates independently with no disclosed parent, subsidiary, or institutional investor.
