Simple Signature Law and Legal Definition

A simple signature is a kind of signature that is subject to ratification and applies to most multilateral treaties. When a State signs the treaty, the signature is subject to ratification, acceptance or approval and the State has not expressed its consent to be bound by the treaty until it ratifies, accepts or approves it. In such a situation, a State that signs a treaty is obliged to refrain, in good faith, from acts that would defeat the object and purpose of the treaty.
