Treaty of Accession to the European Union

The Treaty of Accession is an international agreement that officially allows a country to join the European Union. It outlines the terms, rights, and responsibilities for the new member, including how it will comply with EU laws and policies. This treaty is negotiated and signed by existing EU member states and the candidate country, and then ratified through their respective processes. Once ratified, the accession becomes effective, integrating the new country into the EU's political, economic, and legal systems, enabling participation in decision-making, access to the single market, and adherence to EU standards.
