Information Governance for Law Firms

Law firms face a distinctive information governance challenge. You operate under a professional duty of confidentiality that predates POPIA, but POPIA now adds a statutory framework on top of that professional obligation. The intersection of attorney-client privilege, professional conduct rules, and POPIA creates governance requirements that go beyond what most other sectors face.

The Professional Confidentiality Obligation

The Legal Practice Act and the rules of the Legal Practice Council impose a duty of confidentiality on all legal practitioners. This duty covers all client communications, instructions, and information provided by clients. It survives the end of the client relationship and in some cases extends even after the client’s death.

POPIA adds a statutory layer to this obligation. Client personal information must be processed in compliance with POPIA’s eight conditions, in addition to the professional confidentiality requirement.

Categories of Information Law Firms Process

Law firms routinely handle:

• Client personal information (ID numbers, addresses, financial information, family details)
• Privileged communications and legal advice
• Litigation documents including sensitive testimony and evidence
• Property and conveyancing records
• Trust account records involving multiple parties
• Family law matters (special personal information: relationships, health, children)
• Employment law matters (disciplinary records, health information)
• Criminal law matters (criminal record information)

Multiple categories of POPIA special personal information appear in routine legal practice.

The AI Tool and Privilege Problem

Legal practitioners are beginning to use AI tools for legal research, document drafting, contract review and matter summarisation. The governance risks are severe:

• Loss of privilege: Disclosing privileged communications to a third-party AI tool may constitute a waiver of privilege. Whether this is the case depends on the specific tool, the terms of service, and the circumstances of disclosure. The risk is real and most legal practitioners have not assessed it.
• POPIA violation: Inputting client personal information into a consumer AI tool processes that information for an unauthorised purpose.
• LPC obligations: The Legal Practice Council’s obligations on confidentiality may be broader than POPIA in some respects. Using an AI tool to process client information without client consent may breach professional conduct rules.

Law firms should obtain a legal opinion on the privilege implications of AI tool usage before deploying AI in client-facing work.

Trust Account and Financial Record Governance

Trust account records are subject to detailed regulatory requirements, including retention periods specified by the LPC rules. Conveyancing practices are subject to additional requirements from SARS and the Deeds Registry.

Good document governance — clear naming conventions, organised folder structures, access controls and retention schedules — is not just about POPIA compliance. It is essential to trust account management and regulatory audit readiness.

Third-Party Risk in Legal Practice

Law firms share client information with:

• Counsel and co-counsel
• Expert witnesses
• Process servers
• Court transcription services
• eDiscovery and litigation support providers
• Practice management software vendors
• Cloud storage providers

Each of these is a potential data processor under POPIA. Written data processing agreements should be in place with all service providers who access personal information on the firm’s behalf.

Matter File Management

Many law firms still maintain inconsistent naming conventions for matter files, with practices varying between departments or even between individual fee earners. This creates:

• Difficulty locating documents when fee earners leave
• Version control failures in high-volume matters
• Inability to respond promptly to POPIA subject access requests
• Risk of disclosing the wrong version of a document

A firm-wide matter file naming and folder structure standard, enforced through the practice management system, significantly reduces these risks.

Practical Steps for Law Firm Information Governance

1. Appoint and register an Information Officer
2. Develop a matter file naming and folder structure standard
3. Implement an AI acceptable use policy with specific guidance on client matters and privilege
4. Review all technology vendors and ensure data processing agreements are in place
5. Develop a data breach response procedure aligned with POPIA and LPC notification requirements
6. Train all fee earners and support staff on POPIA obligations and AI tool risks
7. Implement access controls so that only the matter team can access each client file
8. Develop a retention and destruction policy for matter files after closure
