Consumer rights when buying property: what does the CDC guarantee that the developer doesn't tell you?

Many people think the Brazilian Consumer Protection Code is for returning a defective phone — and forget that it also governs the biggest purchase of their lives. Whenever you buy a property from a developer, builder, land subdivider or real estate agency (regular suppliers), it is a consumer relationship: the CDC applies, with an arsenal of protections the company's printed contract rarely mentions.

A real estate consumer relationship is one in which the buyer acquires the property as the end user from a professional supplier. In this article, we will cover the five pillars of the CDC applied to real estate — information, binding advertising, the nullity of abusive clauses, the defects regime and easier access to a defense — and when the CDC does not apply (a purchase between private individuals, governed by the Brazilian Civil Code).

When is a property purchase protected by the CDC?

When there is a professional supplier on one side and an end user on the other (arts. 2 and 3 of the CDC). Buying an off-plan apartment, a unit from the developer's inventory, a lot in a subdivision: a consumer relationship. Buying a used house directly from another family: a civil relationship, governed by the Brazilian Civil Code (hidden defects, loss of title to third parties). The distinction defines deadlines, the burden of proof and the size of your shield — and it is the first question a lawyer asks when reviewing the case.

What does it mean to say that “advertising is binding”?

It means that the brochure, the scale model, the ad and the broker's promise are part of the contract (art. 30 of the CDC), even if the signed instrument says less. An advertised item that goes undelivered gives the consumer the choice in art. 35: demand performance, accept an equivalent, or terminate with damages. The practical corollary: sales material is a legal document — keep everything, from the first ad to the broker's last message.

Which clauses in a real estate contract are considered abusive?

Art. 51 of the CDC strikes down as void any clause that places the consumer at an unfair disadvantage. In the real estate market, the champions: penalties provided only against the buyer (the STJ — Brazil's Superior Court of Justice — allows the penalty clause to be mirrored against a defaulting developer — Repetitive Theme 971), a choice of forum that hampers the consumer's defense, advance waivers of rights, and shifting the business's typical risks onto the consumer. A void clause does not have to be “accepted because I signed”: it simply has no effect.

Improper charges: when is the refund doubled?

Anyone charged an improper amount who pays it is entitled to a refund; where the charge was made in bad faith, the refund is doubled (art. 42, sole paragraph, of the CDC). Recurring examples: the SATI fee (abusive — STJ, Theme 938), fees never agreed to, pre-delivery construction interest charged in breach of the agreement. In parallel, art. 6, VIII, lets the judge shift the burden of proof in favor of the disadvantaged consumer — it is the developer who will have to prove the charge was owed.

A concrete example: Renata's purchase in Tatuapé

Renata bought an R$ 420 thousand apartment from a developer. In the contract: a 10% penalty only against her, a forum in another judicial district and three “service fees” adding up to R$ 14 thousand. Based on the CDC, the extrajudicial notice pointed out the nullity of the clauses (art. 51), demanded a refund of the fees (art. 42) and put on record the advertising material promising a double parking space — absent from the contract. The settlement came before any lawsuit: fees refunded, the double parking space formalized in an amendment and the penalty clause mirrored for both sides. The CDC wasn't “a little help”: it was the difference between accepting and negotiating.

The most common (and costly) mistakes

1. Thinking a signed contract ends the discussion. An abusive clause is void even when signed (art. 51, CDC). Risk: performing obligations that don't exist.
2. Treating the broker's verbal promise as “just talk”. Messages and ads are binding (art. 30). Risk: giving up items you paid for in the price.
3. Paying strange charges without requesting the legal basis in writing. Risk: losing the trail of bad faith that would double the refund.
4. Applying the CDC where it doesn't apply (a purchase between private individuals). Risk: using the wrong deadlines and arguments and missing the Civil Code's correct windows.

Actionable checklist for the real estate consumer

• Confirm whether the seller is a professional supplier (CDC) or a private individual (Civil Code);
• Keep all the advertising and sales conversations;
• Flag in the contract: penalties (are they mutual?), forum, fees and adjustment indexes;
• Demand the legal basis of every extra charge in writing;
• Always complain through a channel with a filed record; keep numbers and dates;
• At an impasse, consider an extrajudicial notice before going to court.

Frequently asked questions

Does the CDC apply to every property purchase?

No. It applies when the seller is a professional supplier — a developer, builder or land subdivider — and the buyer is the end user (arts. 2 and 3 of the CDC). In a purchase between private individuals (a used home sold by a private owner), the Brazilian Civil Code applies, with its own rules on hidden defects and loss of title. The distinction changes deadlines and strategies.

Does a broker's promise over WhatsApp have legal force?

It does. An offer, made through any channel, binds the supplier (art. 30 of the CDC) — and messages from a broker working for the developer form part of the offer. If the promise is not kept, the consumer can demand specific performance, accept an equivalent, or terminate the contract with damages (art. 35 of the CDC). Keep the conversations.

What are the most common abusive clauses in real estate contracts?

A penalty provided only against the buyer (the STJ allows it to be mirrored against the developer — Theme 971), advance waivers of rights, shifting business risks onto the consumer and a choice-of-forum clause that hampers the consumer's defense. Under art. 51 of the CDC, they are null and void — even if the contract was signed without reservations.

I was improperly charged by the developer: do I get double back?

If there was an improper charge that you paid and bad faith is established, yes: art. 42, sole paragraph, of the CDC guarantees a refund of double the amount paid, adjusted for inflation. Without proven bad faith, the refund is the simple amount. Fees such as SATI, already declared abusive by the STJ (Theme 938), are typical candidates for a refund.

When should I see a real estate consumer-law lawyer in São Paulo?

At two moments: before signing — to spot void clauses while you still have bargaining power — and as soon as a strange charge, broken promise or defect appears, because the CDC's deadlines are short (90 days for apparent defects). A good share of cases is resolved out of court when the formal notice arrives well grounded.

The CDC levels the table — but only protects those who invoke it

When buying from a developer or builder, you are not negotiating as equals: you are negotiating against a standard-form contract drafted by the other side. The Brazilian Consumer Protection Code exists precisely to rebalance that table — advertising that binds, abusive clauses that fall, improper charges that come back. Knowing these rights before signing is worth money; knowing them afterwards is still worth a case.

At Falchet e Marques Sociedade de Advogados, a law firm in São Paulo (Av. Paulista), we apply the CDC to property purchases at every stage — reviewing standard-form contracts, recovering charges, enforcing offers and handling defects — working out of court and before the São Paulo State Court (TJSP) and Procon-SP.
