Legal Translation of “deceive” to French: tromper or décevoir?

⚠️ 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
