Ad idem

“Ad idem” is a Latin phrase that means “to the same thing” in English. It is often used in legal contexts to express the agreement or mutual understanding between parties. If parties involved in a contract or negotiation are said to be “ad idem,” it indicates that they have a meeting of the minds, which means that they share a common understanding of the terms, conditions, or subject matter.

In contract law, the principle of “ad idem” is crucial. It ensures that both parties involved in a contract have a shared understanding of the key elements, such as the offer, acceptance, and the subject matter of the agreement. If there is a dispute and it’s determined that the parties were not “ad idem,” it could potentially invalidate the contract due to a lack of genuine agreement.
