Why Australian Businesses Should Avoid AI-Generated Contracts

Australian businesses are increasingly turning to artificial intelligence tools like ChatGPT to draft contracts quickly and cost-effectively. While AI can produce a polished agreement in seconds, the convenience comes with significant risks. Legal professionals across Australia warn that these tools often fail to deliver enforceable, compliant, or even accurate contracts.

AI-generated contracts may seem professional at first glance, but they frequently miss critical clauses, misalign with business goals, or include fabricated legal references. Courts and tribunals in Australia have already encountered cases where AI-drafted agreements led to disputes, compliance failures, or unenforceable terms. Without legal oversight, businesses expose themselves to financial penalties, weakened legal positions, and reputational damage. This article explores the risks of AI-generated contracts and explains why professional legal advice remains essential.

Key takeaways

AI-generated contracts pose significant risks for Australian businesses, including omitted clauses, misaligned terms, and fabricated legal references. Legal professionals have identified issues like "legal drift," where minor AI edits shift risk allocation without notice, potentially weakening protections or creating compliance gaps. Confidentiality is another major concern, as public AI tools lack attorney-client privilege. Unlike lawyers, AI platforms offer no accountability for errors, leaving businesses vulnerable to disputes and financial losses. While AI can assist with preliminary drafts, legal review is critical to ensure compliance, enforceability, and protection of your interests.

How AI Contract Drafting Works (And Why It’s Risky)

AI tools like ChatGPT generate contracts by analysing patterns in millions of documents. They produce language that mimics real agreements but lack genuine legal understanding. This creates a false sense of security—while the document may appear professional, it often fails to address specific business needs or comply with Australian law.

A lawyer can immediately identify gaps in an AI-generated contract, but the AI itself cannot. For example, an AI might produce a seemingly comprehensive agreement that omits essential clauses like dispute resolution mechanisms, confidentiality provisions, or limitation of liability terms. It may also include generic language that doesn’t align with your industry’s risks or commercial strategy. Without legal expertise, these oversights can leave your business exposed to unnecessary risks.

The Problem of "Legal Drift" in AI Contracts

Legal professionals have identified a subtle but serious issue in AI-generated contracts: "legal drift." This occurs when AI makes minor edits that fundamentally alter risk allocation or obligations without drawing attention. For instance, an AI might insert phrases like "subject to the supplier’s discretion" where none was intended, or reference non-existent standards. Individually, these changes may seem harmless, but together, they can weaken protections, create compliance failures, or even render the contract unenforceable.

Legal drift is particularly dangerous because it often goes unnoticed until a dispute arises. Businesses may assume the contract is sound, only to discover too late that critical terms have been altered in ways that shift liability or dilute protections. This highlights the importance of having a lawyer review any contract, even if it was initially drafted using AI.

AI Hallucinations: Fabricated Laws and Cases

One of the most alarming risks of AI-generated contracts is the phenomenon of "hallucinations." This occurs when AI invents legal authorities, case citations, or regulations that don’t exist. In a high-profile U.S. case, lawyers submitted briefs containing six entirely fabricated court cases generated by ChatGPT. The consequences included case dismissal, professional sanctions, and financial penalties. Similar incidents have occurred in Australia, where judges have struck out AI-generated evidence after discovering non-existent case references.

Research indicates that general-purpose AI tools hallucinate on legal queries at an alarmingly high rate. This makes reliance on AI for contract drafting dangerously unreliable. Even if a contract appears well-structured, fabricated legal references can undermine its validity and expose businesses to legal challenges.

Common Pitfalls of AI-Generated Contracts

Australian businesses using AI-generated contracts often encounter the same critical flaws. These issues don’t just create minor inconveniences—they can lead to disputes, financial losses, or legal vulnerabilities. Below are some of the most common pitfalls:

• Missing essential clauses: AI-drafted agreements frequently omit critical terms such as dispute resolution processes, confidentiality provisions, limitation of liability clauses, and compliance obligations under laws like the Australian Consumer Law or Privacy Act 1988 (Cth).
• Jurisdictional errors: AI may reference foreign laws, such as U.S. regulations, instead of Australian standards. It may also fail to address state-specific requirements, leaving businesses poorly protected in disputes.
• Misaligned commercial terms: AI cannot interpret your business strategy or industry risks. It assembles generic language that may not reflect your goals or the other party’s obligations, creating imbalances or unworkable terms.
• Outdated or incorrect provisions: Even when prompted to address Australian law, AI may misrepresent requirements, cite repealed legislation, or overlook recent regulatory changes.
• Confidentiality breaches: Public AI platforms like ChatGPT are not bound by attorney-client privilege. Entering sensitive business details into these tools risks exposing your data to breaches or unintended sharing.

These pitfalls demonstrate why AI-generated contracts often require more time and cost to fix than drafting a proper agreement from scratch. The initial convenience of AI can quickly be outweighed by the need for extensive legal revisions.

Why AI Lacks Legal Accountability

When a lawyer drafts a contract, they assume professional responsibility for its accuracy and enforceability. If errors occur, businesses have recourse: lawyers carry professional indemnity insurance and can be held accountable for negligence. AI, on the other hand, offers none of these protections.

If an AI-generated contract contains flaws that lead to a dispute, there is no one to hold liable. AI platforms disclaim responsibility, software providers offer no insurance, and businesses cannot pursue negligence claims. This lack of accountability is a critical reason why courts and tribunals, including the Federal Court of Australia and NCAT, advise against relying on AI for contract drafting without legal review.

A lawyer’s duty of care ensures that your agreement is legally sound and tailored to your needs. This professional oversight is essential for protecting your business interests and avoiding costly legal disputes.

Can AI Be Used Safely for Contracts?

Some businesses argue that AI can serve as a starting point for contract drafting, with a lawyer reviewing the final document. While this approach has theoretical merit, it introduces new challenges:

• Hidden flaws: AI-generated drafts may contain subtle errors that require extensive legal scrutiny to identify and correct.
• Limited cost savings: The time a lawyer spends reviewing and revising an AI draft often offsets the initial convenience, especially if the document requires significant changes.
• Responsibility shifts: Ultimately, the lawyer—not the AI—must take professional responsibility for the final contract. This means businesses are still paying for legal expertise, but with added risk from the AI’s initial input.

For these reasons, most legal professionals recommend against using AI for contract drafting unless the final document undergoes comprehensive legal review. Even then, the efficiency gains are often modest compared to the potential risks.

Australian Regulatory Warnings on AI Contracts

Australian courts, tribunals, and professional bodies have issued clear guidance on the use of AI in legal documents. Key warnings include:

• Independent verification required: AI-generated legal citations and references must be checked for accuracy.
• No AI evidence without approval: Courts like the Federal Court of Australia prohibit using AI to create affidavits or expert reports without prior judicial consent.
• Disclosure expectations: Parties may need to disclose AI use in formal proceedings, particularly if the document’s reliability is questioned.
• Enforceability risks: Contracts drafted without legal review are more likely to contain flaws that render them unenforceable or open to dispute.

These directives reflect growing concerns about AI’s reliability in legal contexts. The Law Council of Australia and state courts consistently emphasise that AI should supplement—not replace—legal expertise.

The Safer Alternative: Working with a Lawyer

The most effective way to protect your business is to collaborate with a qualified lawyer who understands your industry, commercial goals, and legal obligations. A lawyer will:

• Customise terms to reflect your specific needs and risk tolerance.
• Ensure compliance with relevant legislation, including the Australian Consumer Law, Privacy Act, and Fair Work Act.
• Identify potential loopholes, ambiguities, or unbalanced clauses.
• Negotiate protective provisions that align with your objectives.
• Provide professional accountability if disputes arise.

While AI may continue to evolve, current technology lacks the judgment, contextual awareness, and legal expertise required to draft reliable contracts. Investing in professional legal advice upfront is far less costly than resolving disputes stemming from a defective AI-generated agreement.

FAQs About AI and Contract Drafting

Can AI draft a legally binding contract in Australia?

Technically, yes, if the contract meets all legal requirements such as offer, acceptance, consideration, and intention. However, AI-generated contracts often contain errors, omissions, or non-compliant terms that make them risky or unenforceable. Legal review is strongly recommended to avoid potential disputes.

What’s the biggest risk of using AI for contracts?

The most serious risks include "legal drift," where subtle changes alter obligations, AI hallucinations that fabricate legal references, and missing critical clauses. These issues can lead to disputes, compliance failures, or financial losses for your business.

Can I use AI to draft a contract and then have a lawyer review it?

While possible, this approach often negates the time and cost savings of using AI. Lawyers must thoroughly review and revise AI drafts to ensure accuracy, which can be as involved as drafting a contract from scratch. The added risk of hidden flaws may outweigh the initial convenience.

Are there any types of contracts where AI is safer to use?

Even for simple agreements, AI poses risks. Low-stakes contracts like basic NDAs or service agreements may seem safer, but errors in these documents can still create liabilities. Legal oversight remains critical to ensure enforceability and compliance.

What should I do if I’ve already used AI to draft a contract?

Have a lawyer review the document immediately. They can identify flaws, ensure compliance, and recommend corrections before the contract is signed or disputed. Early legal intervention can prevent costly issues later.
