TL;DR

LawFairy has received authorisation from the Solicitors Regulation Authority (SRA) to operate as a “technology-only” law firm in England and Wales, making it the first to use deterministic AI — rule-based logic rather than large language models — to deliver legal outcomes without traditional lawyers.

How LawFairy works

Unlike AI systems built on probabilistic LLMs that predict likely text, LawFairy uses what it calls “Trusted Legal Intelligence” — a proprietary rule-based logic engine called FairyLogic. Statutory and policy criteria are encoded into structured decision pathways validated by lawyers. The same facts produce the same result every time, with no hallucination risk.

“Unlike probabilistic legal AI, our regulated outcomes are generated through pre-validated statutory rules with a fully auditable reasoning trail,” said co-founder Seb Jenks.

The system initially focuses on UK immigration law, conducting eligibility assessments for Skilled Worker visas, settlement, and citizenship determinations. It generates structured eligibility reports, evidence checklists, and reasoning packs.

Pricing and access

Individual assessments cost £149, with tiered subscription pricing for lawyers and advisers. The company also offers a free SOC code search tool for checking role alignment and salary thresholds before committing to a full assessment. A pro bono initiative with a leading charity and a global law firm will be announced next week.

Regulatory context

LawFairy is the second primarily tech-led law firm to gain SRA approval. Garfield, which uses AI to handle small claims, received approval last year. CEO Raj Panasar emphasised the distinction from LLM-based tools: “Where the law operates through defined rules — fixed thresholds, statutory tests and precise eligibility criteria — technology should apply those rules consistently and transparently.”

Looking forward

The SRA’s approval of a firm operating without traditional lawyers signals an important shift in how legal services can be delivered in England and Wales. Whether the deterministic approach can extend beyond immigration’s rule-dense domain into less structured areas of law will determine how broadly the model scales.
