From our law firm in the Plurinational State of Bolivia, we present an updated guide to help identify the countries with which current extradition agreements exist and the main international instruments that regulate this matter.
What Is Extradition and Why Is It Important?
Extradition is a cooperation procedure between States through which a person wanted by the justice system may be surrendered to the country requesting them, either to be tried or to serve a sentence.

How Is the Existence of an Extradition Treaty Determined?
The existence of a bilateral or multilateral treaty is one of the most important elements in processing an extradition request. When there is no specific agreement, some States may rely on the principle of international reciprocity, through which they offer the same treatment they expect to receive in similar situations.
Therefore, before initiating any international procedure, it is advisable to verify whether a current instrument exists between both countries.

Argentina

Applicable Multilateral Agreements
In addition to bilateral treaties, there are international instruments that may serve as a legal basis for an extradition request when the States involved are parties to them.
MERCOSUR Extradition Agreement
This instrument facilitates cooperation among Member States and Associated States that are part of the regional system.
United Nations Conventions
Certain international conventions related to transnational organized crime, corruption and illicit drug trafficking provide international cooperation mechanisms that may serve as a basis for extradition requests in specific circumstances.
What Happens If There Is No Extradition Treaty?
The absence of a treaty does not necessarily mean that extradition is impossible. In some cases, States may process requests based on the principle of international reciprocity.
Under this criterion, a State expresses its willingness to grant legal cooperation while expecting equivalent treatment if a similar situation arises in the future.
However, the feasibility of this mechanism will depend on the domestic legislation of the requested State and the assessment made by its competent authorities.
Authorities Involved in Extradition Procedures
Extradition requests usually involve the coordinated participation of different institutions, including:
Judicial Authorities
They are responsible for issuing or reviewing extradition requests, as applicable.
Central Authority for International Legal Cooperation
This authority acts as the official communication channel between States for processing requests.
INTERPOL
INTERPOL participates in the location, identification and operational coordination related to internationally wanted persons.
Diplomatic Missions
Diplomatic missions facilitate the formal transmission of documents and communications between the States involved.
Aspects to Verify Before Requesting Extradition
When analyzing the possibility of international extradition, it is important to verify:
- The existence of a current treaty.
- The documentary requirements demanded by the requested State.
- The legal classification of the investigated conduct.
- The validity of the criminal action or sentence.
- The deadlines established in the applicable international instruments.
- The conditions provided under the domestic legislation of the requested country.
In summary, the existence of extradition treaties is a fundamental tool for international legal cooperation and the fight against impunity. There are currently bilateral agreements in force with Argentina, Brazil, Belgium, Chile, Ecuador, Spain, the United States, England, Italy, Mexico, Paraguay, Peru, Portugal and Venezuela, in addition to various multilateral instruments that complement this system of cooperation between States.
