Law favors truth, faith, and certainty.

Explanation

(English-origin maxim — no Latin equivalent; the English title is the original form.) Courts construe instruments to uphold truth over falsehood, good faith over bad faith, and certainty over ambiguity — the law rewards honest dealing and clear expression.

Where this applies

• A party submits forged documents to support a claim, and the court dismisses the case because the law favors truth over deception.
• A seller conceals a known defect in a home, and when the buyer discovers the problem, the court rescinds the sale because the law favors good faith and honest dealing.
• A contract is drafted with deliberately vague terms designed to confuse one party, and the court construes it against the drafter because the law favors certainty over ambiguity.
