The Most Common Mistakes in AI-Generated Contracts – And Why You Don’t Notice Them Right Away

Print

“The contract looked perfect. I only realized it was useless when I needed to enforce it.”
Jiří used an AI tool to draft a loan agreement. Everything seemed reasonable. A year later, when trying to recover the loan, it turned out the contract lacked a clear due date and penalty clause. Legally, the contract had no teeth.

What are the most common mistakes in AI-generated contracts, why they’re not obvious at first glance, and how to avoid them – including practical tips and legal insights.

❌ Common AI mistakes you won’t notice immediately:

  • Formal flaws – missing signature blocks, unclear party identification

  • Lack of deadlines or penalties – making enforcement difficult

  • Outdated or overly generic clauses – ignoring current legal developments

  • Unclear definition of deliverables – no clarity on what’s to be done

  • Copy-paste content without context – AI generates, but doesn’t understand business reality


⚠️ Why you won’t see the problems right away:

  • The language looks legal and professional

  • You don’t know what legal elements are missing

  • AI won’t tell you what’s not in the contract

  • A layperson can’t spot missing key clauses


📚 Real-life example:

A business owner used AI to draft a software development agreement. While the contract looked detailed, it completely skipped over intellectual property rights. When the developer left, the business had no rights to the source code – and couldn’t continue using the software.


✅ Lawyer’s recommendation:

AI isn’t a lawyer. The question isn’t what it can write – but what it doesn’t know to include.
Every important contract deserves a review.
It’s better to catch errors early than deal with legal consequences later.
