"deceive": tromper or décevoir

Q: What is the correct French rendering of "deceive" in legal texts?

Tromper , duper or induire en erreur , depending on register. "The defendant intended to deceive the buyer" reads " le défendeur avait l'intention d'induire l'acheteur en erreur ". Choosing décevoir here would be legally nonsensical.

⚠️ A classic false friend… with serious legal implications

The verb to deceive is a frequent trap for French speakers. Although it resembles décevoir, it has nothing to do with emotional disappointment. In legal contexts, deceive refers to fraudulent conduct, intentional misrepresentation, or deliberate trickery.

⚖️ In Law: To Mislead, Defraud, Intentionally Deceive

Deceive is often associated with fraud, manipulation, or intentional misrepresentation in legal texts, contracts, or proceedings.

Examples:

Fraud involves an intent to deceive → La fraude implique une intention de tromper
The defendant intended to deceive the buyer → Le défendeur avait l’intention d’induire l’acheteur en erreur

👉 Translating deceive as décevoir in this context would be legally nonsensical.

💬 Reflexive Usage: Se leurrer / To Delude Oneself

To deceive oneself often translates as se leurrer, se faire des illusions, or refusing to see reality.

Example:

We must not deceive ourselves → Nous ne devons pas nous leurrer

🕵️‍♂️ Nominal Form: deceit = Tromperie

The noun deceit refers to the act of deceiving, usually deliberate and calculated. It is common in commercial disputes and criminal law.

Example:

The contract was obtained by deceit → Le contrat a été obtenu par tromperie

Where deceit vitiates consent, the deceived party may rescind the contract and the wrongdoer is liable for the resulting harm. Rendering these shades of deliberate misrepresentation faithfully calls for the same care needed when transposing procedural notions across the common law divide.
