Hidden Defects in Property: Buyer Rights in Brazil
Direct Answer
A buyer of property with a hidden defect (flaw not perceptible at purchase) may opt for rescission (returning the property with full refund) or proportional price reduction (art. 442, CC). The deadline to claim is 1 year from discovery of the defect for real estate. Structural defects, infiltrations, and foundation problems are the most common hidden defects and may generate additional material and moral damages compensation.
What Is a Hidden Defect
A hidden defect (vício redibitório) is a flaw existing in the property at the time of sale that was not perceptible to the buyer through ordinary inspection and that renders the property unfit for use or reduces its value (art. 441, CC).
Legal Requirements
To constitute a hidden defect, the following must be present:
- Pre-existence: The defect already existed at the time of purchase
- Concealment: Was not perceptible through ordinary examination
- Severity: Renders the property unfit or significantly reduces its value
- Buyer’s lack of knowledge: The buyer was unaware of the defect
Hidden Defect vs. Apparent Defect
| Aspect | Hidden Defect | Apparent Defect |
|---|---|---|
| Perceptibility | Not visible on inspection | Visible on inspection |
| Timing | Discovered after purchase | Identifiable before purchase |
| Deadline | 1 year from discovery | 1 year from delivery |
| Protection | CC arts. 441-446 | Implicit acceptance by the buyer |

Available Legal Actions
Rescission Action (Ação Redibitória — Art. 441, CC)
Seeks to void the purchase contract and restore parties to their prior state.
The buyer receives:
- Full refund of the price paid, with monetary adjustment
- Reimbursement of contract expenses (deed, registration, ITBI tax)
- Compensation for improvements made
- Moral damages (if applicable)
The buyer returns:
- The property to the seller
Applicable when: The defect is so severe it renders the property unfit for use or when the buyer would not have purchased it knowing of the defect.
Price Reduction Action (Ação Estimatória / Quanti Minoris — Art. 442, CC)
Seeks proportional price reduction while the buyer keeps the property.
The buyer receives:
- Refund of the difference between the price paid and the actual value with the defect
- Compensation for the cost of repairing the defect
- Moral damages (if applicable)
Applicable when: The defect reduces the property’s value but does not render it unfit for use, and the buyer prefers to keep it.
Supplementary Compensation Action
Regardless of the rescission or price reduction action, the buyer may combine a claim for material and moral damages (art. 443, CC). If the seller knew of the defect and concealed it, they must pay for losses and damages.
Deadlines
Limitation Period (Art. 445, CC)
| Asset Type | Period |
|---|---|
| Movable property | 30 days from delivery |
| Real property | 1 year from delivery |
| Hidden defect (movable) | 30 days from discovery (max 180 days from delivery) |
| Hidden defect (real property) | 1 year from discovery |
Period Calculation
For hidden defects, the period begins from the date the defect manifests, not from property delivery. Courts have been flexible regarding defects manifesting years after purchase, especially serious structural defects.
Consumer Relations Period
When the purchase involves a consumer relationship (construction company/developer as supplier), the CDC applies:
- Apparent defect: 90 days from delivery (art. 26, II, CDC)
- Hidden defect: 90 days from discovery (art. 26, paragraph 3, CDC)
- Product defect (accident): 5 years from discovery (art. 27, CDC) Learn more about our business law services.
Legal vs. Contractual Warranty
The legal warranty (CC and CDC) cannot be waived. The contractual warranty (offered by the construction company) adds to the legal one. Construction company warranties typically vary:
| Component | Typical Warranty |
|---|---|
| Structure and foundation | 5 years |
| Waterproofing | 5 years |
| Plumbing | 5 years |
| Electrical installations | 5 years |
| Windows and frames | 2 years |
| Paint and finishes | 1 year |
| Equipment | Per manufacturer |
How to Prove a Hidden Defect
Expert Report
Expert evidence is the primary means of proof. The expert (civil engineer or architect) evaluates:
- The existence and extent of the defect
- Whether the defect predated the purchase
- Whether it was perceptible through ordinary inspection
- The cost of repair or correction
- The impact on the property’s value
Other Evidence
- Dated photographs and videos of the defect
- Reports from construction companies
- Formal notifications to the seller documenting the complaint
- Testimony from neighbors or professionals
- Market comparisons demonstrating devaluation
Precautionary Inspection
A precautionary inspection before purchase is highly recommended, especially for used properties. An inspection by a qualified engineer can identify defects that would go unnoticed during a normal visit.
Seller’s Liability
Individual Seller
Liable for hidden defects regardless of fault (strict liability under art. 441, CC). If the seller knew of the defect and concealed it, they are also liable for losses and damages (art. 443, CC).
Construction Company/Developer
Strictly liable under the CDC (art. 12). Liability is joint between the construction company, developer, and other participants in the production chain. The structural warranty period is 5 years (art. 618, CC).
Real Estate Agent
The agent may be held liable if they knew of the defect and failed to inform the buyer, violating the duty of information (art. 723, CC).
Structural vs. Aesthetic Defects
| Aspect | Structural | Aesthetic |
|---|---|---|
| Impact | Compromises safety or habitability | Affects appearance, not safety |
| Severity | High | Variable |
| Applicable action | Rescission or price reduction | Price reduction (usually) |
| Compensation value | High | Proportional to impact |
| Examples | Beam cracks, structural infiltration | Irregular paint, defective grouting |
