AI Hallucinations

Last updated:

An AI hallucination is a misleading or fabricated output from an AI system that appears to be convincing despite being incorrect. In the legal/contract management context, hallucinations can produce invented clauses, inaccurate summaries, incorrect legal interpretations or references to non-existent information.

How It Works

Big language models don’t do fact-checking. They “predict" patterns in the data. That allows them to generate useful content fast, but it can also lead to outputs that sound plausible but are wrong.

Hallucinations can arise when an AI system has insufficient context, misinterprets information or is asked a question it is not designed to answer. These limitations will be critical as legal teams adopt AI tools more and more.

Why It Matters for Legal & CLM Teams

Precision matters in the world of legal professionals. One bad clause summary, obligation analysis or risk assessment can create compliance issues and business risk. This is why organisations that deploy AI for legal work usually have review processes and governance controls in place.

Teams leveraging SpotDraft AI and similar technologies should treat AI outputs as a starting point rather than a final legal conclusion. Human review remains a critical part of the process.

Example Use Case

A legal team uploads a vendor agreement and asks an AI tool to identify unusual clauses. The system correctly flags several provisions but also states that the agreement contains a liability cap that is not actually present.

If the output is accepted without verification, stakeholders may make decisions based on inaccurate information. This is one reason many organizations combine AI tools with structured AI-assisted review and manual validation processes.

How It Relates to Adjacent Concepts

AI hallucinations are often closely related to AI contract drafting and AI contract review, since both rely on the outputs of AI. They are also applicable to contract intelligence initiatives, where the accuracy of extracted information has direct implications for reporting and decision-making.

As organisations adopt more advanced technologies such as agentic AI, reducing the risk of hallucination becomes a key element of legal AI governance and operational best practices.

FAQs

Are all AI systems hallucinating?

In some situations, most generative AI systems have a tendency to hallucinate. The frequency and severity will depend on the model used, the available context and the task being performed.

Can AI hallucinations be eliminated entirely?

No. However, organisations can significantly mitigate risk through human review, approved data sources, governance controls and legal-specific AI tools.

Why do AI hallucinations matter for legal work?

Legal teams need the right information. Risk can be introduced by hallucinated clauses, summaries or legal interpretations if not identified before decisions are made.
