The risks of using AI for your legal work

Artificial intelligence is everywhere now. From drafting emails to summarising documents, it promises speed, convenience and lower costs. It’s hardly surprising that many business owners are starting to turn to AI for their legal work too.

Used carefully, AI can be a helpful productivity tool. Used in the wrong way, it can expose you to serious legal, financial and commercial risk. The problem is not that AI exists, it’s how confidently people rely on it for work that carries real-world consequences.

Below, we look at the key risks of using AI for legal matters, and why human legal advice still matters.

No accountability if something goes wrong

If a solicitor gives you incorrect advice, there is professional accountability. They are regulated, insured and owe you a duty of care.

AI offers none of that. If an AI-generated contract leads to a dispute, a failed transaction or a financial loss, there is no recourse. The responsibility, and the risk, sits entirely with you.

For business owners, that lack of accountability should be a serious red flag.

AI does not understand the law, it predicts language

AI tools don’t “know” the law. They generate text based on patterns in data. That means they can sound authoritative while being subtly (or completely) wrong.

Legal work depends on precision, interpretation and context. A clause that looks reasonable on the page can have unintended consequences once it interacts with legislation, case law or the rest of your contract. AI cannot reliably judge how a document would be interpreted by a court, a lender or a counterparty.

In short, fluent wording is not the same as legal accuracy.

Laws change, AI responses don’t keep up

The law evolves constantly. Legislation is amended, new cases are decided, and regulatory guidance changes.

AI tools are not guaranteed to reflect the current legal position, particularly in fast-moving areas such as employment, data protection, and corporate law. Even small changes in the law can make a clause outdated or unenforceable.

Relying on AI-generated legal documents risks building decisions on rules that no longer apply.

Confidentiality and data security concerns

Legal work often involves highly sensitive information: financial data, shareholder arrangements, personal guarantees, commercial strategy or employment issues.

When you input that information into an AI tool, you may be storing or processing it on systems outside your control. Depending on the platform, that data could be retained, analysed or used to train future models.

This creates real risks around confidentiality, data protection and GDPR compliance. Particularly for businesses handling client or employee information.

AI can’t judge commercial risk or intent

Legal advice is rarely just about what the law says. It’s about how it applies to your situation and what level of risk is acceptable for you.

A lawyer will ask questions. They will probe your objectives, highlight red flags, and help you weigh legal risk against commercial reality. AI cannot do that. It cannot read between the lines of a negotiation, spot where a counterparty is overreaching, or advise you when not to proceed.

That judgement is often the most valuable part of legal advice — and it’s something AI simply cannot replicate.

Where AI can help

AI can be useful as a supporting tool. For example, it may help you:

• Generate a rough list of questions to raise with your lawyer
• Summarise a long document for initial understanding
• Improve the clarity of non-legal, internal communications

Where it should not be used in isolation is:

• Drafting or signing contracts
• Giving legal advice
• Making decisions involving liability, guarantees or regulatory compliance

In those situations, AI should never replace qualified legal input.

The bottom line

AI is impressive, and it will undoubtedly play a growing role in how professionals work. But law is not just about words on a page. It’s about responsibility, risk, interpretation and judgement.

Using AI to shortcut proper legal advice may feel efficient in the short term, but the cost of getting it wrong can be significant. Both financially and personally.

If you are unsure about a legal issue, contract or transaction, it’s always safer to speak to a qualified lawyer who understands your business and can advise you properly.
