Generally, states confirm acceptance of a treaty's terms by signature.

That is correct. In international law, states usually confirm their acceptance of a treaty's terms by signing the treaty. The act of signature represents the intention of the state to be bound by the treaty and serves as a preliminary step towards its formal ratification or accession. However, it is important to note that the signature alone is not sufficient to make a state legally bound by the treaty. The treaty needs to be ratified, accepted, approved, or acceded to according to the state's internal procedures before it becomes legally binding.
