Can AI Draft a Contract? What the Risks Are (A Straight Answer for 2026)

AI tools like ChatGPT or Gemini can draft a contract skeleton quickly and make a genuinely good starting point, but they do not guarantee that the content is correct under the latest Thai law, they do not check whether a clause counts as an "unfair contract term" under the notifications of Thailand's Office of the Consumer Protection Board (OCPB, สคบ.), and they do not automatically add the PDPA provisions that certain contract types require. Most importantly, the text an AI produces is not a legally binding document until it is signed in a way that satisfies Section 9 of the Electronic Transactions Act B.E. 2544 (2001).

This article is written for people who already use AI to draft contracts, or who are thinking about trying it. It is not an anti-AI piece, and it is not an article claiming AI can replace a lawyer entirely. It is a straight answer to what AI does well, what it cannot do, and what you need to add before a block of text becomes a contract you can actually use.

TL;DR: AI is good at drafting contract structure and language, but it does not guarantee accuracy against the latest Thai law, does not screen for unfair contract terms, and does not add PDPA provisions on its own. Before using an AI draft for real, run three checks: the content, its consistency with the law, and a signing method that is binding under Section 9.

What you should know

• AI is a good starting point for drafting a contract, but it is not the finish line.
• The three main risks are legal references that may be outdated, clauses that may qualify as unfair contract terms, and PDPA provisions that AI does not add automatically.
• AI-drafted text has no legal binding force until it is signed under Section 9 of the Electronic Transactions Act B.E. 2544 (2001).
• AI and lawyers are not an either-or choice; they do different jobs.

Can AI draft a contract?

Yes, and it is a good starting point for contract drafting. LLMs like ChatGPT or Gemini perform well at three main things: structuring a contract so all the standard sections are present (parties, purpose, payment terms, termination), producing a first draft from a rough idea, and translating or rewording text so it reads more clearly. For someone who has never drafted a contract before, starting with AI is clearly better than starting from a blank page.

What you must keep separate is that AI only "helps write text". It does not verify that the text complies with the latest version of Thai law, and it does not make the document legally binding.

What are the risks of using AI to draft a contract?

There are three main risks: the law the AI cites may be outdated, clauses may qualify as unfair contract terms without you realizing it, and required PDPA provisions may simply be missing. Each risk works differently and is worth understanding on its own.

1. Legal references that may be outdated or inaccurate General-purpose LLMs can cite the wrong statute name, section number, or year in force, especially on topics where the law changes often. This risk is widely known among people who use AI for legal work, so every legal reference an AI produces should always be checked against an official source before you rely on it.

2. Clauses that may qualify as unfair contract terms Certain contract types in Thailand fall under notifications of the Contract Committee of the Office of the Consumer Protection Board (OCPB), which prescribe clauses that are prohibited, or clauses that must be included, for specific contract types. General-purpose AI is not automatically trained on these specialized notifications.

3. PDPA provisions that are not added automatically Contracts that collect personal data, such as a lease that asks for a copy of an ID card, or a medical consent form, must include provisions under the Personal Data Protection Act B.E. 2562 (2019) (PDPA). If you do not specifically instruct the AI to add PDPA language, that part usually goes missing from the draft without anyone noticing.

Is an AI-drafted contract legally binding?

Text drafted by AI is not, on its own, legally binding. What makes a contract binding is a valid signature, not the quality of the wording. Under Section 9 of the Electronic Transactions Act, an electronic signature must be able to identify the signer and show that the signer accepted the content of that document.

Put simply: however polished an AI-drafted contract looks, it remains "just text" until every party signs it using a method that is binding under the law. This connects to another common misconception: taking an AI-drafted document and "signing" it by pasting a signature image into the PDF, which has its own weaknesses entirely separate from any content problems.

What should you check before using an AI-drafted contract?

Before sending an AI-drafted contract for signing, always check these 4 points.

1. Verify every legal reference against an official source, such as the Royal Thai Government Gazette website or the relevant authority directly. Never trust a section number or year the AI cites without checking.
2. Check whether this contract type has required or prohibited clauses under OCPB notifications, especially consumer-facing contracts such as leases or installment sale agreements.
3. Add PDPA provisions if the contract collects personal data, whether names, phone numbers, addresses, ID card numbers, or health information.
4. Sign with a system that satisfies Section 9: one that identifies the signer through a reliable method, such as OTP identity verification with a timestamped audit trail, not just a typed name at the end of an email or a pasted signature image.

AI drafting vs lawyer drafting: what's the difference?

AI and lawyers are not competitors you must choose between; they complement each other at different points. AI is fast and cheap for a first draft. A lawyer is precise at checking legal compliance and case-specific risk.

Jabmue does not claim to replace lawyers, and does not claim to draft contracts with AI for you. What Jabmue does is close the final gap once the contract content is ready, whether it was drafted by AI, a lawyer, or both: getting the document properly formatted and signed in a way that is actually legally binding, with signer identity verification and an audit trail that follows the standard set by Section 9.

Frequently asked questions

Can ChatGPT draft a lease agreement?

Yes, but you should check lease-specific requirements, such as registration when the lease term exceeds 3 years, and you should sign it with a system that is binding under Section 9, not just a typed name at the end of a message.

If an AI-drafted contract turns out to be unlawful, who is responsible?

As a general principle, the user or the signing party who actually uses the contract is responsible for its content, not the AI provider that helped draft the text.

Is there a way to review an AI-drafted contract before using it?

Have a lawyer or qualified expert review the content before real-world use, especially for high-value contracts or contracts with meaningful dispute risk.

How accurate is AI at drafting contracts in Thai?

Sentence structure and section organization are handled well, but some specialized legal terms may be off, or may not match the terminology actually used in Thai legal practice. Have someone with legal knowledge review the draft before using it.

Can an AI-drafted contract be signed online?

Yes, provided the signing system satisfies Section 9: it can verify the signer's identity and records the signing time as evidence. See our comparison of online document signing tools in Thailand at Comparison of online document signing tools in Thailand

Conclusion

AI is a good starting point for drafting a contract, but it is not the finish line. Three things remain a human's responsibility: verifying that the law cited is current, screening for clauses that may qualify as unfair contract terms, and signing the document in a way that is actually legally binding.

If you have a finished contract, whether drafted by AI or by a lawyer, the final step that makes it usable is sending it for signature through a system with identity verification and a complete audit trail. Try it free to see how Jabmue handles that final step.
