# ChatGPT for legal work: how lawyers can use it properly > Source: https://beamon.ai/chatgpt-for-legal-work-how-lawyers-can-use-it-properly/ Many lawyers have already tried ChatGPT, with very mixed experiences. Either the result was surprisingly helpful, or it was generic, inaccurate and of little use. In practice, this is rarely down to the tool itself. It is almost always down to how it's used. This guide shows how ChatGPT can be used sensibly in legal work: which tasks it's suited to, what good prompts look like, where its limits are, and when [a specialised legal AI tool is the better choice](https://beamon.ai/what-sets-legal-ai-apart-from-general-purpose-ai-tools/). ## Why ChatGPT requires particular care in legal work ChatGPT is a general-purpose language model. It was trained to write persuasively, not to be legally correct. In practice, this difference is often underestimated. The model can't look up legislation in real time. It doesn't know about recent judgments. It has no access to client data or a firm's internal precedents. And it hallucinates: it invents case citations, statutory references and literature references that sound plausible but don't actually exist. German courts documented this problem in [several decisions in 2025](https://beamon.ai/why-lawyers-have-been-sanctioned-for-using-chatgpt/). In its order of 29 April 2025 (ref. 5 U 1/25), the Higher Regional Court (OLG) of Celle found that a lawyer had cited four supposed decisions from various higher regional courts. None of them could be found in juris or beck-online. The Local Court (Amtsgericht) of Cologne (ref. 312 F 130/25) reached a similar conclusion: every source in a brief had been made up. The court made clear that this kind of conduct undermines trust in lawyers' submissions. The courts' message is clear: professional duties of care apply in full, including when AI is used. ## Which legal tasks ChatGPT is suited to ChatGPT is strongest when it comes to first drafts, not when a reliable final result is required. Suitable tasks include: ChatGPT is less suitable wherever reliable legal knowledge is required, for example case citations, current statutory references, compliance reviews or direct client communication without subsequent review. ## The foundation: how prompts for legal tasks work The most common mistake when using ChatGPT isn't the wrong tool, [it's an unclear prompt](https://beamon.ai/introduction-to-prompting-for-lawyers/). A vague prompt leads to a vague answer. A structured prompt delivers a much more usable result. A good legal prompt contains four elements: Example: “*You are an experienced employment lawyer in Germany. Review the following dismissal protection clause from the employee's perspective. Identify any provisions that could breach the Dismissal Protection Act (KSchG) or current Federal Court of Justice (BGH) case law. Structure your analysis as an issues list with a short rationale and a severity rating (high, medium, low).”* The result can be used straight away, but as the basis for your own review, not as a replacement for it. ## Step by step: typical use cases ### Analysing contract clauses ChatGPT can quickly check clauses for potential problem areas, from a clearly defined perspective and in a structured format. Important: the output is not a legal opinion. Every point it identifies must be checked against the current legal position. ### Structuring and summarising facts Long sets of facts or documents can be structured well with a clearly worded prompt. This saves time when preparing for client meetings or internal discussions. Example: “*Summarise the following facts for an internal case handover. Maximum 10 bullet points. Focus on the parties, the point in dispute, deadlines, open legal questions and next steps.”* ### First drafts of standard documents For recurring documents such as NDAs, simple contracts or client letters, ChatGPT can produce a usable first draft. However, it always needs to be adapted, especially to the firm's standards, the current legal position and the specific client. ## What ChatGPT can't replace ChatGPT doesn't replace legal judgement. It processes language; it doesn't assess the legal position. In particular, the following can't be delegated: The 2025 court decisions show clearly what happens when this line is crossed: sanctions, loss of trust and possible professional consequences. AI is no substitute for a lawyer's diligence; it's a tool that requires exactly that diligence. ## When a specialised legal AI tool makes sense ChatGPT reaches its limits as soon as confidential data, verified sources or traceable workflows are involved. This is exactly where specialised solutions such as [BEAMON](https://beamon.ai/) come in.
