How it works

Retrieval first, generation second — every step grounded in trusted content.

  1. Step 1

    Interprets your legal task

    Understands what you are trying to achieve and identifies the best approach to support that task.

  2. Step 2

    Searches across primary and secondary sources

    Runs a unified query across legislation, case law, commentary and practical guidance in one search.

  3. Step 3

    Applies authority, currency and recency checks

    Prioritises what is most reliable and up to date using legal validation methods.

  4. Step 4

    Reranks using legal context

    Reorders results using legal-specific logic so the most relevant authorities appear first.

  5. Step 5

    Validates every citation

    Checks that all authorities are correctly applied and current — nothing left to chance.

  6. Step 6

    Builds a grounded response

    Generates your answer using only the legal sources identified in the process, with linkable citations.

Lexis+ AI in practice

Real workflows from practitioners across UK firms — research, advisory and drafting.

Property Litigation

Emergency advice, backed by authority

A barrister received a frantic call from a solicitor acting for a commercial landlord who had repossessed a property. Bailiffs arrived claiming access rights via a utility warrant tied to a previous tenant.

Lexis+ AI surfaced cited authority and practical guidance in minutes, letting the barrister respond on the call with verifiable references.

I had the answer before the bailiffs had finished arguing on the doorstep.
Commercial Contracts

Drafting a clause with full context

A mid-level associate needed to confirm that a post-termination confidentiality clause would survive the end of a settlement agreement.

The AI returned a cited case-law summary, a Practical Guidance drafting note and a linked precedent clause — all in one view.

I didn't just get an answer. I got context, guidance, precedent wording and legal commentary all in one view.
Tax

Instant prep before a client call

A tax adviser preparing for a client meeting on multiple dwellings relief asked: 'What's the latest case law on MDR in the past 6 months?'

Returned the most recent First-Tier Tribunal ruling, its status on appeal and similar pending cases — all sources cited, linked and open for validation.

I walked into that meeting better informed than anyone else at the table — in under 10 minutes.
Disputes & Litigation

Reducing anxiety for junior lawyers

A junior solicitor used Lexis+ AI to quietly check legal points against Lexis-sourced content instead of waiting to ask a partner.

Authority-backed verification became a learning tool — confidence grew without compromising accuracy.

I used to panic about asking something I should know. Now I check it privately, get it right and learn faster.

Frequently asked questions

Is Lexis+ AI safe to use with client data?
Yes. Conversations are encrypted (AES-256 at rest, TLS 1.2+ in transit), prompts are purged after 90 days or on request, your content never trains the underlying models, and the platform is independently audited to SOC 2 Type 2 standards with ongoing vulnerability testing and UK-aligned privacy controls.
Where is data hosted?
Private large language models process data in the local region — Europe (including UK), US, Canada or Australia — depending on your subscription. Models run in secure environments with no access by the underlying model providers.
Does Lexis+ AI provide real citations?
Every answer is grounded in LexisNexis content with linkable citations to legislation, case law and commentary — including the All England Law Reports, ICLR decisions, Halsbury's Laws of England, Civil Court Practice (the Red Book) and EF&P / Atkin's precedents — so you can trace and verify each statement.
How does it differ from generic AI tools?
Lexis+ AI is retrieval-first, generation-second: it interprets the legal task, searches trusted UK legal sources, re-ranks results with legal-specific logic, validates every citation and only then generates a response. The language matches UK practice, the content is from a trusted legal provider, and the answers are auditable rather than improvised.
Which practice areas are covered?
Practical guidance is written by legal experts across 42 practice areas, with primary law, secondary commentary, encyclopedic works and precedents available across every major area of UK practice.
Does it integrate with Microsoft Word?
Yes — Lexis Create+ brings the same trusted content and AI capabilities directly into Microsoft Word, with clause suggestions, redlining and inline research and guidance.
