A Treaty of Accession to the European Union is an intergovernmental treaty of the European Union that specifies the terms under which an applicant state becomes a member of the European Union. It represents the fundamental act to enable a state to become a member of the EU, thereby binding it to the fundamental principles of the union. In addition to the Treaty of Accession, a Final Act of Accession is signed. The Final Act registers the results of the accession negotiations, including declarations made by the parties. It also lays down arrangements for the period between signing and entry into force of the treaty.
The negotiation process to draft a Treaty of Accession between a "candidate country" and the European Union involves the agreement to the chapters of the acquis—35 as of May 2024. All reforms necessitate structural changes to the national legislation in order to accommodate for the institutional bodies of the EU and delegated power associated with it. [1] Upon the agreement of EU governments, including the unanimous decision by the European Council, negotiations are screened by the European Commission. The candidate country must submit a common position with the EU on its action plans and interim benchmarks; no set time frame is guaranteed or outlined, and negotiations are heavily contingent on the degree of reform and alignment that a candidate country had from its status quo ante . [2]
Once negotiations conclude, the EU and candidate country work towards developing the candidate's Treaty of Accession. However, the treaty only becomes finalized and binding once it is approved by all three EU decision-making bodies (European Commission, European Council, European Parliament), signed by the candidate country and existing member states, and ratified by the candidate country and existing member states at the national scale. [2] The treaty then enters into force the day following ratification, which is agreed upon beforehand. [3] It outlines the candidate country's obligations and rights, including the implementation and adoption of the acquis . [4] Accordingly, each accession treaty puts forth broad principles and rules, resulting in a change to primary law. Following the signing of the Treaty of Accession, “acceding countries” are promised full membership status upon the mutually agreed terms and benefit from certain procedures. For example, the acceding country may sit in on legislative proceedings in the European Parliament through a consultation procedure and comment on draft proposals. In other EU bodies, they may hold an active observer status, meaning they may spectate all proceedings but have no voting powers until their full membership status. [5]
The Western Balkan countries seeking accession have a special process. Prior to the drafting of a Treaty of Accession and the status of a “candidate country” before that, Western Balkan nations require an extra step. [2] A country from the Western Balkans can be offered a “potential candidate country” contingent on reforms related to economic stability and regional cooperation before it may be considered for candidacy at large. In the meantime, such countries maintain various association or stabilization agreements meant to construct dialogue on mutual rights and obligations that would precede accession.
Ukraine's unique potential accession status to the EU is a variation of the general rule.

The European Economic Area (EEA) was established via the Agreement on the European Economic Area, an international agreement which enables the extension of the European Union's single market to member states of the European Free Trade Association. The EEA links the EU member states and three of the four EFTA states into an internal market governed by the same basic rules. These rules aim to enable free movement of persons, goods, services, and capital within the European single market, including the freedom to choose residence in any country within this area. The EEA was established on 1 January 1994 upon entry into force of the EEA Agreement. The contracting parties are the EU, its member states, and Iceland, Liechtenstein, and Norway. New members of EFTA would not automatically become party to the EEA Agreement, as each EFTA State decides on its own whether it applies to be party to the EEA Agreement or not. According to Article 128 of the EEA Agreement, "any European State becoming a member of the Community shall, and the Swiss Confederation or any European State becoming a member of EFTA may, apply to become a party to this Agreement. It shall address its application to the EEA Council." EFTA does not envisage political integration. It does not issue legislation, nor does it establish a customs union. Schengen is not a part of the EEA Agreement. However, all of the four EFTA States participate in Schengen and Dublin through bilateral agreements. They all apply the provisions of the relevant Acquis.
The European Union (EU) has expanded a number of times throughout its history by way of the accession of new member states to the Union. To join the EU, a state needs to fulfil economic and political conditions called the Copenhagen criteria, which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the Maastricht Treaty, each current member state and the European Parliament must agree to any enlargement. The process of enlargement is sometimes referred to as European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws.
A European Union Association Agreement or simply Association Agreement (AA) is a treaty between the European Union (EU), its Member States and a non-EU country that creates a framework for co-operation between them. Areas frequently covered by such agreements include the development of political, trade, social, cultural and security links.
The Energy Community, commonly referred to as the Energy Community for South East Europe (ECSEE), is an international organization consisting of the European Union (EU) and a number of non-EU countries. It aims to extend the EU internal energy market to wider Southeast Europe. The members commit to implement relevant EU energy acquis communautaire, to develop an adequate regulatory framework and to liberalize their energy markets in line with the acquis under the founding Treaty.
In talks with countries that have expressed a wish to join the European Union, the EU typically concludes Association Agreements in exchange for commitments to political, economic, trade, or human rights reform in that country. In exchange, the country may be offered tariff-free access to some or all EU markets, and financial or technical assistance.
Relations between the European Union (EU) and Moldova are currently shaped via the European Neighbourhood Policy (ENP), an EU foreign policy instrument dealing with countries bordering its member states.
