In modern conditions, crime acquires new transnational characteristics and requires adaptation to innovative methods of crime investigation. This specificity actualises the need to create joint investigative teams. The relevance of the topic is due to the tendency to improve the functioning of one of the forms of international cooperation in criminal proceedings – the joint investigation team. The purpose of the study was to address key issues of crime investigation by joint investigation teams and demonstrate their place in law enforcement activities. The primary methods employed in the study were comparative law, formal legal analysis, case studies, terminological analysis, legal hermeneutics, along with other general methods of inquiry, including induction and deduction, forecasting and abstraction, analysis, and synthesis. When solving the tasks of criminal proceedings on the facts of investigation of international crimes and crimes of an international nature, the competent authorities of states interact in various forms of international cooperation. There should be a growing awareness of the need for progressive tools for enhanced police and judicial cooperation to achieve the objectives of pre-trial investigation of crimes. The tasks of the competent authorities of different states in the joint investigation of international crimes and international crimes were reviewed. It was proven that ensuring law and order in the field of investigation of transnational crime directly depends on the functioning of a special form of international cooperation – the creation of joint investigative teams. It was recommended to concentrate on the specifics of conducting investigative procedural actions, applying tactical techniques, considering forensic innovations and algorithms for using joint methods in the investigation of crimes in national and international dimensions
