Definitive Signature Law and Legal Definition
A state provides a preliminary endorsement of a treaty or other instrument by signing it. However, mere signing does not create a binding legal obligation but does demonstrate the State’s intent to examine the treaty domestically and consider ratifying it. Definitive signature is the kind of signature that is not subject to ratification. A definitive signature is used by a state where the state expresses its consent to be bound by a treaty by signing the treaty without the need for ratification, acceptance or approval. A State may definitively sign a treaty only when the treaty so permits.
