[Frequently asked questions](#frequently-asked-questions) AI can draft a legal document in minutes, and good legal AI is highly accurate. But any AI tool can occasionally produce text that sounds right and is wrong. A **solicitor's check** is a review of your finished document by a qualified solicitor, who confirms it fits your situation and the law and fixes anything that does not. AI plus a solicitor's check gives you speed and peace of mind. **In short:** - AI tools can "hallucinate": produce confident, plausible text that is inaccurate, out of date or written for the wrong jurisdiction. - Courts, the Solicitors Regulation Authority (SRA) and the Law Society all say AI output must be checked before anyone relies on it. - A solicitor's check looks at legal accuracy, missing or unsuitable clauses, jurisdiction, formalities and consistency of details. - On Robot Lawyer's Verified plan, every finished document is checked by a qualified solicitor and returned Solicitor-Verified within 24 hours. [See how our documents are verified](https://robotlawyer.co/how-our-documents-are-verified). ## What is an AI-generated legal document? An **AI-generated legal document** is a contract, letter, will, policy or other legal text drafted wholly or partly by artificial intelligence, usually a large language model (LLM), from a prompt or a set of answers you give it. General-purpose chatbots write from whatever you type. Purpose-built legal AI, like Robot Lawyer's, drafts from structured questionnaires and lawyer-written drafting instructions for each document type. Either way, it is a draft written by software, so it should be checked before you rely on it. ## What is an AI hallucination? An **AI hallucination** is an output that is presented as accurate but is false, misleading or not supported by any real source. The judiciary's [AI guidance for judicial office holders](https://www.judiciary.uk/wp-content/uploads/2025/10/Artificial-Intelligence-AI-Guidance-for-Judicial-Office-Holders-2.pdf) (England and Wales, October 2025) defines them as "incorrect or misleading results that AI models generate". The [Law Society](https://www.lawsociety.org.uk/topics/ai-and-lawtech/generative-ai-the-essentials) describes them as outputs that are "presented as accurate but are illogical, nonsensical, factually incorrect or do not reflect the training data". Hallucinations happen because an LLM predicts the most likely next words. It does not look answers up in an authoritative legal database. The [SRA's Risk Outlook report on AI](https://www.sra.org.uk/sra/research-publications/artificial-intelligence-legal-market/) explains that these systems "do not have a concept of 'reality'", so they can produce "highly plausible but incorrect results". ### Real examples from UK courts Two reported cases show how convincing invented law can look: - **Harber v HMRC \[2023\] UKFTT 1007 (TC):** a taxpayer representing herself gave the First-tier Tribunal summaries of nine tribunal decisions supporting her case. None of them were genuine; the Tribunal found they had been generated by AI ([read the decision](https://caselaw.nationalarchives.gov.uk/ukftt/tc/2023/1007)). - **Ayinde v London Borough of Haringey and Al-Haroun v Qatar National Bank \[2025\] EWHC 1383 (Admin):** the High Court (Divisional Court) dealt with two cases involving fictitious citations. In Al-Haroun, 18 of the 45 citations put before the court did not exist. The court said freely available AI tools "are not capable of conducting reliable legal research" and that lawyers have a duty to check AI research against authoritative sources ([read the judgment](https://www.judiciary.uk/judgments/ayinde-v-london-borough-of-haringey-and-al-haroun-v-qatar-national-bank/)). These were court submissions, not contracts, but the lesson applies to any legal document: polished wording is not proof of accuracy. The SRA has since issued a [warning notice on the misuse of AI](https://www.sra.org.uk/solicitors/guidance/misuse-ai/) about "fictitious cases, references or seemingly factual assertions that may appear convincing despite having no basis in fact". ## Common errors in AI-drafted legal documents Any AI tool can make these five mistakes. A careful human check is how they get caught. ### 1. Made-up clauses, laws or cases An AI may add a clause that refers to a statute, section or case that does not exist, or quote real legislation incorrectly. The judicial guidance warns that AI tools may "make up fictitious cases, citations or quotes, or refer to legislation, articles or legal texts that do not exist" ([judicial guidance PDF](https://www.judiciary.uk/wp-content/uploads/2025/10/Artificial-Intelligence-AI-Guidance-for-Judicial-Office-Holders-2.pdf)). ### 2. The wrong jurisdiction Law differs from country to country, and even within the UK. The same judicial guidance notes that public chatbots' "view" of the law "is often based heavily on US and historic law". A clause that works in California or New York may be meaningless or unenforceable elsewhere. **Example (England and Wales):** a will must be in writing and signed in the presence of 2 witnesses aged 18 or over, who then sign it in your presence ([GOV.UK](https://www.gov.uk/make-will/make-sure-your-will-is-legal); [Wills Act 1837, s. 9](https://www.legislation.gov.uk/ukpga/Will4and1Vict/7/26/section/9)). GOV.UK points out that [different rules apply in Scotland and Northern Ireland](https://www.gov.uk/make-will). A document drafted for the wrong place can fail on formalities alone. ### 3. Missing mandatory terms Some documents must contain specific information by law. If a tool leaves it out, the document may still look complete. **Example (Great Britain: England, Wales and Scotland):** employers must give employees and workers a written statement of employment particulars. The principal statement must be provided on the first day of employment and must include set items such as pay, hours, holiday entitlement and job title, with a wider written statement due within 2 months ([GOV.UK](https://www.gov.uk/employment-contracts-and-conditions/written-statement-of-employment-particulars); [Employment Rights Act 1996, s. 1](https://www.legislation.gov.uk/ukpga/1996/18/section/1)). ### 4. Outdated law AI models learn from data gathered up to a point in time. The judicial guidance warns that AI output "may be inaccurate, incomplete, misleading or out of date". For instance, the rules on written statements of employment particulars in Great Britain were changed with effect from 6 April 2020 ([Employment Rights (Miscellaneous Amendments) Regulations 2019](https://www.legislation.gov.uk/uksi/2019/731/regulation/1/made)). A tool relying on older material could describe the old rules. ### 5. Inconsistent details Long documents give an AI more chances to contradict itself: a name spelled two ways, dates or amounts that differ between clauses, or a defined term used with different meanings. Ambiguity like this is what leads to disputes. ## Are AI-generated legal documents valid? An AI-generated legal document is not invalid simply because AI helped write it. Whether it is valid and enforceable depends on what it says and how it is made: whether it meets the legal requirements for that type of document in the relevant jurisdiction, whether the terms are clear and lawful, and whether it is signed, witnessed or executed correctly. A document can look professional and still fail one of those tests. A solicitor's review tells you whether yours passes them. ## What does a solicitor's check catch? A solicitor reads your finished document against your circumstances and the current law. A good check covers: - **Suitability:** whether the document actually fits your situation and the answers you gave. - **Legal accuracy:** whether references to legislation and legal rules are real, correctly stated and up to date. - **Missing or unsuitable clauses:** whether any clause should be added, removed or adjusted. - **Jurisdiction and formalities:** whether it is written for the right legal system and will be signed, witnessed or executed in the right way. - **Consistency:** names, dates, amounts and defined terms that match throughout. - **Clarity:** wording that says what you intend, with good drafting practice and formatting. Solicitors in England and Wales are regulated by the SRA, and the Law Society's [guidance on generative AI](https://www.lawsociety.org.uk/topics/ai-and-lawtech/generative-ai-the-essentials) is clear that a solicitor's professional duties apply "regardless of whether AI or other technologies were used to assist with that work". A solicitor's check adds a regulated professional's judgement to the speed of AI. ## Why AI plus a solicitor's check is the right combination This is not a choice between AI and lawyers. AI turns your answers into a tailored, structured draft in minutes. A solicitor brings judgement and accountability: spotting what is missing, questioning what looks odd and confirming the document suits you. The SRA's [Risk Outlook report](https://www.sra.org.uk/sra/research-publications/artificial-intelligence-legal-market/) recommends using AI to "speed up and automate routine tasks, supporting rather than replacing human judgment", and warns not to "trust an AI system to judge its own accuracy". Pairing legal AI with a solicitor's review follows that advice. ## How Robot Lawyer verifies documents Robot Lawyer combines bespoke legal AI with lawyers at two levels: 1. **Lawyer-maintained documents (all plans).** Our lawyers write and update the questionnaires and drafting instructions our AI follows for each document type, and track changes in the law. 2. **A solicitor check of your finished document (Verified plan).** A qualified solicitor reviews the specific document generated for you, makes any amendments needed and returns it with our **Solicitor-Verified** badge within 24 hours. **Plans:** - **Verified: £24.99 a month**, with a 7-day free trial. Includes the solicitor check of your finished documents, returned within 24 hours. - **Essentials: £13.99 a month.** Lets you generate documents with our lawyer-maintained AI, but does not include the solicitor check of your finished document. **Jurisdiction:** documents are drafted for your own country's laws. Our solicitors are qualified in England and Wales; for documents governed by another country's law, including Scotland and Northern Ireland, we also recommend a local lawyer's check. [How our documents are verified](https://robotlawyer.co/how-our-documents-are-verified) Ready to start? Popular documents include a [contract of employment](https://robotlawyer.co/documents/contract-of-employment), a [last will and testament](https://robotlawyer.co/documents/last-will-and-testament) and a [non-disclosure agreement](https://robotlawyer.co/documents/non-disclosure-agreement). You can also [compare our plans](https://robotlawyer.co/pricing). ## Checklist: before you rely on any AI-drafted document 1. Confirm which country's law the document follows, and that it says so. 2. Look up every law or case it mentions on an official source such as legislation.gov.uk or the National Archives' Find Case Law. 3. Check the terms the law requires are all there. 4. Check names, dates, amounts and defined terms match throughout. 5. Check the signing, witnessing or execution requirements. 6. Have a qualified lawyer review it before you sign, send or rely on it. For contracts in particular, see our [contract review checklist](https://robotlawyer.co/news/your-essential-10-point-contract-review-checklist-for-2026). ## Frequently asked questions ### Are AI-generated legal documents legally valid? They can be. A document is not invalid just because AI drafted it. Validity depends on whether it meets the legal requirements for its type and jurisdiction, including any signing or witnessing rules. A solicitor's check confirms this for your document. ### Can AI replace a solicitor? Not entirely. AI produces a fast, tailored first draft, but courts and regulators in England and Wales say AI output must be checked by someone who can verify it. The best results come from AI plus a solicitor's review. ### What does "Solicitor-Verified" mean on Robot Lawyer? It means a qualified solicitor has reviewed that specific document and made any amendments needed. It applies to documents checked under the Verified plan. [Read how verification works](https://robotlawyer.co/how-our-documents-are-verified). ### Which plan includes the solicitor check, and how long does it take? The Verified plan (£24.99 a month, with a 7-day free trial). Documents are verified within 24 hours. The Essentials plan (£13.99 a month) does not include a solicitor check of your finished document. [See pricing](https://robotlawyer.co/pricing). ### Is my document checked if it is not for England and Wales? Yes, on the Verified plan, but our solicitors are qualified in England and Wales. For documents governed by another country's law, including Scotland and Northern Ireland, we also recommend a check by a local lawyer.
