Data Security and AI in Conveyancing Firms

Client data is sacred. Here is how to evaluate whether an AI tool meets the security standards your firm — and your regulator — demands.

Data security is a nonnegotiable requirement for any technology used in legal practice. The ICO guidance for law firms and SRA cybersecurity guidance set clear expectations for how client data must be handled — expectations that apply equally to AI tools as to any other technology in the firm's stack. If you're unfamiliar with any legal terms used in this article, our conveyancing glossary explains them in plain English.

For conveyancers evaluating AI tools, data security should be among the first considerations, not an afterthought.

The Data Security Landscape

Conveyancing files contain some of the most sensitive personal data in legal practice: identity documents, financial information, property details, and transaction records. This data is subject to:

  • GDPR — including data minimisation, purpose limitation, and storage limitation principles
  • SRA Standards and Regulations — requiring confidentiality and data protection
  • CLC requirements — similar obligations for licensed conveyancers
  • Client expectations — an increasingly dataaware public expects robust protection

Key Questions for AI Tool Evaluation

Where Is Data Processed?

Understanding where client data goes when it is submitted to an AI tool is fundamental. Is data processed within the UK or EEA? Are international transfers involved? If so, what safeguards are in place?

Is Data Used for Training?

Some AI providers use submitted data to improve their models. For legal work, this is generally unacceptable — client data must not be used for any purpose beyond the specific analysis requested. Any AI tool used in conveyancing should provide a clear commitment that client data is not used for model training.

How Long Is Data Retained?

Data retention policies should be transparent and proportionate. Client data submitted for AI analysis should be retained only for as long as necessary to deliver the analysis, plus a reasonable period for audit purposes, and then securely deleted.

What Security Controls Are in Place?

Encryption at rest and in transit, access controls, audit logging, and incident response procedures should all be documented and verifiable.

How Is MultiTenancy Managed?

In a multifirm environment, strict data segregation must prevent any possibility of one firm's data being visible to or accessible by another firm.

Regulatory Expectations

The SRA has been increasingly active in setting expectations for technology governance. Firms are expected to:

1. Understand the technology they use 2. Assess the risks associated with that technology 3. Implement appropriate controls 4. Monitor compliance on an ongoing basis 5. Document their approach

This applies to AI tools just as it does to case management systems, email platforms, and cloud storage.

Frequently Asked Questions

Does using AI create additional data protection obligations?

Yes. If the AI provider is a data processor under GDPR, you need a data processing agreement. You should conduct a data protection impact assessment (DPIA) for any AI tool that processes client data at scale. Your privacy notice may need updating to inform clients about AI processing.

Can I use AI tools for confidential client matters?

Yes, provided the AI tool meets appropriate security standards and the data handling arrangements are consistent with your duty of confidentiality. Evaluate the tool against the same criteria you would apply to any other technology that handles client data.

What should I include in my AI governance policy?

Your AI governance policy should cover: approved tools and their permitted uses, data handling and security requirements, human review procedures, staff training requirements, incident response procedures, and regular review and update processes.
