Off-Plan in Spain: Why “Illustration Only” Disclaimers Are Legally Worthless

I’m writing this post after discovering last week that many developers are increasingly using in their off-plan marketing and contracts a clause such as:

“The advertising is for illustration purposes only and does not form part of the contract.”

I want to explain why this wording is contrary to Spanish law and therefore null and void – in other words, it is deemed not written. The developer simply has no legal power to decide that their advertising is not binding, as we explain in more detail below.

If you’re already in the middle of an off-plan purchase, you may also find our complete guide to buying off-plan property in Spain helpful.

1. What is happening in practice?

Developers selling off-plan are using:

• Brochures, renders, videos, websites, glossy sales packs
• Promises of views, facilities, qualities/finishings, services, surroundings, etc.

At the same time, they insert phrases like:

• “The advertising is for illustration purposes only and is not contractual”
• “Images do not create any contractual rights”

The real aim of this wording is:

• To shield themselves from claims if the delivered property does not match what was advertised
• To try to neutralise the binding effect of the advertising

The problem is that Spanish consumer law says the opposite.
We explain why in more depth in our article on off-plan misrepresentation in Spain.

2. What does Spanish law say about advertising?

Under Spanish consumer law (in particular, the Spanish Consumer and User Protection Act – TRLGDCU):

• The content of any offer, promotion or advertising,
• and the legal and economic conditions and guarantees offered,
• are binding and enforceable against the trader,
• even if they do not appear expressly in the written contract.

In plain language:

• What the developer advertises about the property forms part of what is promised.
• And the buyer has the right to demand it.

On top of that:

• Clauses that are contrary to mandatory consumer law or that limit rights granted to consumers are:
  • Null and void, and
  • Are treated as if they did not exist in the contract.

---

3. SUMMARY TABLE: What happens with “the advertising is only illustrative”?

What the developer wants to achieve	What the law actually says
That the advertising (brochures, renders, website…) “does not bind them”.	Advertising does bind them: its content is enforceable, even if not copied word for word in the contract.
Avoid claims if the property does not match what was advertised.	If the delivered property does not correspond to the advertising, there may be breach / lack of conformity.
Make the buyer “give up” rights granted by law, without saying it openly.	Consumer rights are non-waivable; clauses contrary to them are null and void, and deemed not written.

Conclusion from the table:
That sentence does not “vaccinate” the developer against claims. It is a clause contrary to the law, null and without legal effect.

---

4. Why is it null and void?

Because it directly collides with two core ideas of Spanish consumer law:

1. Advertising becomes part of the contract

• The law states that advertising and offers are incorporated into the contract,
  even if the contract does not reproduce them literally.
• A clause stating that “advertising is not contractual” contradicts a mandatory rule.

2. Protection against unfair terms

A standard term that:

• Limits rights granted by law to the consumer, or
• Creates a significant imbalance to the detriment of the consumer,

is considered an unfair term, and therefore:

• Null and void, and
• Deemed not written.

In short:

The developer cannot legally “switch off” the effect of their own advertising just by inserting a standard sentence in the small print.

For buyers already facing problems, our off-plan deposit claims section explains what can be done when things go wrong.

5. Quick Q&A

1. Can the developer include this sentence in the brochure or in the contract?

They can type it, yes.
But legally, if it contradicts consumer law, it has no effect and is treated as if it were not there.

---

2. So, does the advertising still count even if it says “for illustration purposes only”?

Yes.

If you are a consumer buying an off-plan property in Spain:

• Whatever has been advertised with sufficient specific detail (views, communal areas, services, finishings, sizes, orientation, layout, amenities, etc.)
• Forms part of what you were promised and can be enforced.

The “for illustration purposes only” disclaimer does not erase those legitimate expectations.

---

3. What if the finished property does not match the brochure?

It depends on the seriousness of the difference, but in general you may consider:

• Demanding compliance (correction of what can still be corrected)
• Asking for a reduction in the price or compensation for damages
• Termination of the contract (returning the property and recovering your money), where the difference between what was promised and what was delivered is essential

The key is to analyse:

• What exactly was promised in the advertising
• What has actually been delivered

---

4. What evidence should I keep as a buyer?

It is very important to keep:

• Brochures, renders, videos, screenshots of the developer’s website or online adverts
• Sales emails, WhatsApp messages, sales packs describing the property, views, facilities, services, etc.
• The initial off-plan purchase contract and any annexes or specifications

All of this helps to prove what you were actually promised when you decided to buy.

---

5. What if the contract says one thing and the advertising says something better?

In consumer contracts:

• The more favourable condition for the consumer prevails.
• If the advertising offers something better than the wording of the contract, that advertised content can be integrated and enforced as part of the agreement.

So, trying to neutralise the advertising with a standard disclaimer is not legally effective.
