In international relations, law or documentation, an “annex” means an addition, supplement or supplement to a main document or treaty. Annexes play an important role in ensuring that all relevant details are included in official documents without overcomplicating the main text. They are essential to providing clarity, precision and completeness to legal, diplomatic and technical agreements.
