Risks of Using ChatGPT & Gemini in Conveyancing

It is tempting. A complex lease clause, an unfamiliar lender requirement, a confusing environmental search result — and ChatGPT, Gemini or Claude is right there, ready to answer in seconds. Many conveyancers have tried it. Some use it regularly.

But the convenience masks serious professional risks that every conveyancer, compliance officer, and managing partner needs to understand before these tools become embedded in daily practice.

The Attraction — and the Trap

Generalpurpose AI models are remarkably fluent. They can summarise documents, draft correspondence, explain legal concepts, and answer questions with apparent confidence. For a timepressed conveyancer handling forty active files, the appeal is obvious.

Consider this scenario: A fee earner is reviewing a local authority search for a property in a former mining area. The search mentions "standing advice" from the Coal Authority but the fee earner is unsure of the implications. They paste the relevant paragraph into ChatGPT and ask: "What are the risks here?"

The response is articulate, wellstructured, and sounds authoritative. It mentions subsidence risk, the need for a mining report, and even references the Coal Authority's Interactive Map Viewer. It feels helpful.

But here is the problem. The response may be entirely fabricated. The case law it cites may not exist. The specific regulatory requirements it references may be outdated, incomplete, or simply wrong. And crucially, the model has no access to the actual documents on the file — it is generating a plausiblesounding answer based on statistical patterns, not evidence.

Five Core Risks of Using Consumer AI in Conveyancing

1. Data Protection and Client Confidentiality

This is the most immediate and serious risk. When a conveyancer pastes client information, property details, or document extracts into ChatGPT, Gemini, or Claude, that data is transmitted to servers operated by OpenAI, Google, or Anthropic — typically located outside the United Kingdom.

Under the UK GDPR and the Data Protection Act 2018, solicitors and licensed conveyancers are data controllers with strict obligations regarding the processing and transfer of personal data. Pasting client names, addresses, financial information, or ID documents into a consumer AI tool almost certainly constitutes a data transfer that the client has not consented to.

The Solicitors Regulation Authority (SRA) has explicitly warned firms about the risks of inputting confidential client data into AI systems without proper safeguards. The Council for Licensed Conveyancers (CLC) takes a similar position: firms must ensure any technology used in practice complies with data protection obligations.

The risk is not theoretical. If a data breach occurs — or a client discovers their personal information was processed by a thirdparty AI without consent — the firm faces regulatory action, a complaint to the Information Commissioner's Office (ICO), and potential negligence claims.

2. AI Training on Your Client Data

Most consumer AI platforms use input data to improve their models unless users specifically opt out — and even then, the terms of service may permit data retention for safety monitoring or abuse detection.

This means that client information pasted into ChatGPT could, in principle, influence future model outputs. Confidential details about a property transaction, a client's financial position, or the terms of a private negotiation could become part of the training data that shapes responses to other users.

For a profession built on the duty of confidentiality, this is fundamentally incompatible with professional obligations. The Law Society's guidance on AI emphasises that firms must understand how data is processed by any AI tool they adopt.

3. Legal Accuracy — The Hallucination Problem

Generalpurpose AI models are not legal databases. They do not have access to uptodate legislation, case law, or regulatory guidance unless specifically connected to authoritative sources. They generate responses based on patterns learned during training — and they do so with complete confidence, whether the output is accurate or not.

In conveyancing, the consequences of inaccurate information can be severe:

• An incorrect statement about SDLT liability could cost a client thousands of pounds
• A misunderstanding of lender handbook requirements could delay or collapse a transaction
• A wrong interpretation of a restrictive covenant could expose the firm to a negligence claim
• Outdated guidance on the Building Safety Act 2022 could leave material safety risks unreported

A real example of the danger: A conveyancer asks Claude about the current SDLT thresholds for firsttime buyers. The model confidently states a threshold that was correct eighteen months ago but has since changed. The conveyancer relies on this in their client advice. The client overpays — or underpays and faces an HMRC penalty. The firm is exposed.

AI hallucination in legal work is not a minor inconvenience. It is a professional negligence risk that every firm must take seriously.

4. No Audit Trail or Accountability

When a conveyancer uses ChatGPT to inform a decision, there is no audit trail linking the AI output to the file. If a complaint arises — or worse, a negligence claim — the firm cannot demonstrate what information was relied upon, when it was obtained, or how it was verified.

The SRA's supervision expectations require firms to maintain adequate records of decisionmaking. A conversation in a consumer chatbot does not meet this standard. Responses can be edited, deleted, or lost entirely. There is no version control, no evidence trail, and no integration with the firm's case management system.

For PI insurers assessing risk, the use of unregulated AI tools without audit trails is a growing concern. Firms that cannot demonstrate structured, accountable decisionmaking processes may face higher premiums — or find it harder to obtain cover at all.

5. No DomainSpecific Knowledge Base

Perhaps the most fundamental limitation is that generalpurpose AI models know nothing about your specific transaction. They have not read the title register. They have not seen the search results. They do not know the lender's Part 2 requirements. They cannot crossreference the environmental search against the local authority search against the drainage report.

They are, at best, guessing based on general knowledge. At worst, they are fabricating answers that sound plausible but are entirely disconnected from the evidence on the file.

This is the critical difference between a consumer AI tool and a purposebuilt conveyancing AI. A purposebuilt system ingests the actual documents, crossreferences findings across multiple sources, checks compliance against specific lender requirements, and generates outputs grounded in the evidence — with citations back to the source material.

How LexSentinel Is Different

LexSentinel was built specifically to address these risks. Every design decision reflects the realities of professional conveyancing practice:

• No client data leaves the secure environment. Documents are processed within a controlled architecture. Client data is never used for model training and is never shared with thirdparty AI providers for their own purposes. Our Privacy Policy explicitly prohibits training on client data.
• Domainspecific knowledge base. LexSentinel's AI agents are grounded in a curated knowledge base covering property law, regulatory frameworks, lender requirements, and environmental risk — maintained and updated by legal professionals.
• Evidencebased outputs only. Every finding, flag, and recommendation is tied to specific evidence in the uploaded documents. The system does not speculate, guess, or hallucinate. If the evidence is not in the file, the AI says so.
• Full audit trail. Every AI interaction is logged with timestamps, user identification, document references, and version control. This creates a defensible record for compliance, supervision, and — if necessary — PI claims.
• Structured review methodology. Rather than answering openended questions, LexSentinel follows a structured review framework that systematically checks every aspect of the file against a comprehensive risk matrix.

The Regulatory Direction of Travel

The SRA, CLC, and Law Society are all moving towards clearer guidance on AI use in legal practice. The direction is consistent: firms must understand what AI tools they are using, how client data is processed, and whether outputs are reliable.

Firms that adopt generalpurpose AI tools without proper governance are likely to face increasing scrutiny. Those that invest in purposebuilt, professionally compliant AI tools will be better positioned — both for regulatory compliance and for the confidence of their clients and PI insurers.

Frequently Asked Questions

Can I use ChatGPT for conveyancing if I remove client names?

Anonymising data reduces but does not eliminate risk. Property addresses, transaction values, and other contextual details can still identify individuals. The ICO considers any data that could be used to identify a person — directly or indirectly — as personal data. Removing names alone is unlikely to satisfy your data protection obligations.

Is it safe to use Gemini or Claude for legal research?

For general legal research — understanding a concept, exploring a question — these tools can be useful starting points. But they must never be relied upon for specific advice, current legislation, or regulatory requirements without independent verification against authoritative sources. The Law Society's practice notes provide further guidance.

How is LexSentinel different from ChatGPT?

LexSentinel is a purposebuilt AI conveyancing assistant designed specifically for residential property transactions. Unlike ChatGPT, it processes your actual case documents, crossreferences findings across multiple sources, checks lender compliance, and generates evidencebased outputs with full audit trails. Client data is never used for model training.

Will my PI insurer be concerned if I use consumer AI?

Increasingly, yes. PI insurers are asking firms about their technology governance, including AI use. Firms that can demonstrate structured, accountable AI processes — with audit trails and evidencebased outputs — are better positioned than those using unregulated consumer tools without governance frameworks.

Does the SRA allow AI in conveyancing?

The SRA does not prohibit AI use, but it expects firms to understand the risks, maintain proper supervision, and ensure compliance with data protection and professional conduct obligations. The SRA's guidance on AI makes clear that responsibility for client work remains with the regulated individual, regardless of what technology is used.
