Cloud computing has emerged as a critical infrastructure for the storage and processing of digital information, posing significant challenges to the collection, preservation, and admissibility of digital evidence in judicial settings. This article presents a structured narrative review of scientific literature and international standards on digital forensics in cloud environments, aiming to identify key legal and technical criteria that influence the evidentiary validity of electronic data. The analysis of 22 peer-reviewed studies reveals methodological fragmentation, limited integration of regulatory frameworks such as ISO/IEC 27037 and the Budapest Convention, and a lack of empirical validation, particularly in Latin American contexts. Additionally, issues related to cross-jurisdictional interoperability and the absence of standardized forensic protocols contribute to procedural uncertainty. In response, the article proposes an adaptive methodological guide grounded in principles of integrity, traceability, and legal admissibility, with the goal of strengthening digital chain of custody practices in distributed computing environments. The findings contribute to the interdisciplinary debate on digital justice and underscore the urgency of implementing scalable, interoperable, and legally sound solutions that align with the evolving demands of judicial systems.
