Why AI Isn’t Responsible for Your Contract – You Are

Print

“I used AI to draft my contract. No one told me that if it’s wrong, I’ll pay.”
Petr used a popular online tool to create a contract. It looked fine. But when the other party breached the agreement, the court found it invalid due to a missing signing clause. Petr paid the damages – AI bore no responsibility.

Who is responsible for errors in an AI-generated contract, when a contract may be invalid, what to do if AI misses something, and why human review remains essential.

⚖️ Who’s liable for mistakes in an AI-generated contract?

AI isn’t a contracting party. It’s not an author or a lawyer.
It’s just a tool that generates text based on your input.

You – the user – are fully responsible.

  • AI lacks legal personality.

  • It doesn’t provide legal services.

  • It gives no warranty for the result.


🔍 When do risks or invalidity arise?

  • Missing formal requirements (form, signatures, specific clauses)

  • Ambiguous wording – unclear obligations or terms

  • Non-compliance with local laws – e.g., consumer protection rules

  • Ineffective clauses – AI doesn’t follow current case law or local legal practices


🛠️ What you can do:

  • Have the AI draft reviewed by a lawyer

  • For more important contracts, use a fully tailored legal service

  • Don’t blindly trust “smart tools” that don’t account for legal consequences


📚 Real-life example:

A company used AI to create a framework agreement with a supplier.
Due to vague warranty language, the supplier avoided liability for defective goods. The court ruled in favor of the supplier – the “smart contract” didn’t protect the client.


✅ Lawyer’s recommendation:

AI can be a helpful assistant – but you bear the legal risk.
If a contract fails, the court won’t care who generated it – only what’s written in it matters.
