Lawyers may face negligence exposure if they fail to use artificial intelligence where it is a reasonable professional tool. The issue is not whether AI must always be used, but whether the standard of care in a particular matter makes its use relevant to competent legal practice. The reported position places AI within the wider question of professional skill, judgment and efficiency.
In negligence terms, the central question is whether a reasonably competent lawyer in the same circumstances would have used AI to assist with the work. If AI is capable of improving accuracy, speed or consistency in routine tasks, a failure to consider it may be criticised where that omission contributes to an avoidable error. The legal risk is therefore tied to the outcome of the work and to the reasonableness of the lawyer’s approach, not to technology for its own sake.
This does not mean that lawyers are obliged to adopt AI indiscriminately. Any use must remain controlled, checked and suitable for the task in hand. A lawyer who relies on AI without proper review may still fall below the required standard, just as a lawyer who ignores a tool that would have materially reduced the risk of error may face criticism. The relevant point is that professional competence now includes an informed judgment about when AI is appropriate, and when it is not.
The practical implication for legal practice is that firms should not treat AI as optional in every context or as a substitute for legal judgment. Decisions about whether to use it should be made consciously and defensibly, with attention to the nature of the work, the risk of mistake and the need for human verification. Where a lawyer chooses not to use AI, there should be a clear professional reason for that choice if the omission later becomes relevant to a negligence claim.
The concern is especially acute where legal work is repetitive, document-heavy or time-sensitive, because the cost of missed issues may be significant. Even then, the duty remains one of competence and care rather than blind automation. A lawyer must still exercise independent judgment, supervise outputs and ensure that any technology used supports, rather than displaces, professional responsibility. That approach reduces the risk that either non-use or misuse of AI becomes evidence of substandard practice.
For clients, the development is significant because it signals that technology choices may increasingly form part of the assessment of professional performance. For lawyers, it means that the failure to engage with available AI tools may no longer be seen merely as a matter of preference or caution. It can, in the right circumstances, become part of the negligence analysis if the omission is unreasonable and causes loss.
Lawyers should therefore assess AI as a potential element of competent service, because a failure to consider a sensible and relevant tool may itself create professional negligence risk.
