T&Cs, Legal Notices, Contracts: Why AI Can Mislead You, and How to Use It Anyway
By Anis Hammouche·November 10, 2026
AI can produce terms and conditions of sale or legal notices in a few minutes. The text looks complete and well presented, and it can be wrong for your case. It does not know your exact status, does not check the texts in force, and is not liable for its errors. You can use it as a working draft, provided you check each mention against an official source or have a professional review it.
Why it is risky
A legal document depends on details: the exact status of your business, the applicable regime, the mandatory mentions, the deadlines, the competent court. AI produces generic text. It fills gaps with common formulas, sometimes wrong for you.
Four risks come up often:
- A status described wrongly. A sole trader and a company do not have to display the same mentions.
- A missing mention. An omission is not visible when you read the text. It shows up at the time of a dispute.
- An outdated rule. Texts change. A model trained on old data can cite a rule that no longer exists.
- An unbalanced clause. AI does not know what protects you or exposes you in your situation.
The text seems right because it is well written. That is exactly the trap.
What is mandatory, what depends on you
The rules differ depending on whether you sell to individuals or to professionals. For professionals, the service-public.fr page on T&Cs states that T&Cs are not mandatory. If you write them, you must send them to a professional customer who asks for them. If they exist, certain mentions must appear in them: sale terms, prices, payment terms, late-payment penalties.
For individuals, the information to give before the sale is mandatory, and the list is longer. It also depends on where the contract is concluded: in a shop, at a distance, online. These mentions include in particular the right of withdrawal, the consumer mediator and the legal guarantees.
Legal notices on a website are mandatory for a professional site. According to the service-public.fr page on mentions for a professional website, they include the identity of the company or sole trader, contact details, the registration number, the VAT number where applicable, and information about the host. Some are conditional, such as the publication director.
| Document | What AI can do | What you check | Who validates |
|---|---|---|---|
| Website legal notices | List the sections to display | Each mention against the official sheet for your status | You, with the service-public.fr sheet |
| T&Cs between professionals | Propose a structure and basic wording | Mandatory mentions if you write them, and payment deadlines | You, and a professional if the amounts are high |
| T&Cs for individuals | Propose a starting outline | Right of withdrawal, mediator, guarantees, depending on how you sell | A legal professional |
| Service contract | Summarize the points to frame | Scope, deadlines, liability, termination, ownership of deliverables | A legal professional |
| Specific clause (confidentiality, subcontracting) | Propose wording | That it matches what you actually do | A legal professional |
How to use it anyway
AI is useful for structuring and listing what needs to be covered. It becomes dangerous as soon as you copy without reading. Here is a method that keeps the time saving.
- Give it facts, not a vague request. Your status, your type of clients, how you sell, your payment terms, what you deliver. The more precise the facts, the less it fills gaps with generic text.
- Ask for a list, not a final text. For example: "List the mentions to check for a sole trader who sells services to professionals. Do not write the clause."
- Check each line against the source. For legal notices and T&Cs, the official service-public.fr page is the reference. Tick each mention one by one.
- Reread figures and deadlines. These are the points most often wrong. Check each one against the source before using it.
- Have contracts that commit money reviewed. A major service contract, a liability clause, a transfer of rights: a legal professional reads, you decide.
The draft saves time on structure. Human review remains the only way to know whether the text protects you.
Example: a payment clause
Asking AI for a payment clause often gives a standard deadline and a standard late-payment penalty. The text can look correct. Yet the rules on deadlines and penalties are framed by law, and the figures must match the law in force.
In practice, you do not copy the clause. You note the points to check: the maximum deadline allowed, the penalty rate, the flat-rate recovery indemnity. You check them on the service-public.fr page dedicated to T&Cs between professionals, then write the clause from those elements.
Frequently asked questions
Can I publish T&Cs generated by AI on my website? You can publish them if you have checked each one and they match your status and how you sell. Publishing without checking makes you liable, not the tool.
Can AI replace a lawyer? No. It can prepare a draft and a list of points to address. A professional brings an analysis of your situation and a responsibility the tool does not have.
What if I am not sure whether a mention applies to me? Start with the official service-public.fr page for your status. If doubt remains, ask a professional before publishing.
Do legal notices change? They can, and so can your activity. Reread them whenever your status or activity changes, and at least once a year.
