Short answer. It depends on whether you had a duty to disclose. Under Article 1339, silence constitutes fraud only when there is a legal duty to reveal the facts — such as when the parties are in a confidential relationship. Ordinary commercial silence, without such a duty, does not automatically amount to fraud.
What the law says
Failure to disclose facts, when there is a duty to reveal them, as when the parties are bound by confidential relations, constitutes fraud.

Silence as fraud — the duty requirement
Article 1339 sets a clear threshold: not every silence is fraud. Keeping quiet about a fact constitutes fraud only when there is a duty to reveal it. The article gives confidential relations as the clearest example of such a duty — fiduciary relationships, close family dealings, or arrangements where one party places special trust in the other. In those contexts, the party holding information cannot simply stay silent and claim they made no false statement; their silence itself becomes the deception.
When a duty to disclose arises in property sales
In a sale of property, the duty to disclose depends on the nature of the defect and the relationship between buyer and seller. Hidden defects that are material to the value or fitness of the property — defects the buyer could not discover by ordinary inspection — may create a disclosure obligation independent of Article 1339, grounded in the warranty provisions of the Civil Code on sales. If the seller knows of such a defect and stays silent specifically to prevent the buyer from discovering it and withdrawing, that conduct can be characterized as fraud. The question is whether the silence was calculated to induce the buyer's consent.
Confidential relations — what the article contemplates
The phrase bound by confidential relations covers more than professional fiduciaries. It includes any relationship where one party reasonably depends on the other's candor and would not ordinarily investigate independently. A principal and agent, a trustee and beneficiary, partners, and family members transacting among themselves can all fall within this category. If you and the buyer were in such a relationship, your knowledge of a material defect and deliberate non-disclosure would likely satisfy the fraud element that the Civil Code requires for annulment of the contract.
Practical consequences of fraudulent concealment
If a court finds that your silence constituted fraud under Article 1339, the contract of sale may be annullable at the buyer's option. The buyer may seek rescission and the return of what they paid, or may claim damages for the loss caused by the concealed defect. Fraud also prevents the statute of limitations from running until the defrauded party knew or should have known of the deceit. Whether your specific situation created a duty to disclose depends on all the facts — the nature of the defect, the relationship between the parties, and what a reasonable buyer in the same position would have expected to be told.
