The rapid growth of cybercrime has significantly increased the importance of digital evidence in criminal investigations and judicial proceedings. However, ensuring the admissibility and reliability of electronic evidence remains a complex challenge due to technological advancements, evolving legal standards, cross-border investigations, and concerns regarding evidence integrity. This narrative review examines the legal and forensic dimensions of digital evidence by synthesizing contemporary literature on its sources, characteristics, governing legal frameworks, and the factors influencing its acceptance in court. The review discusses key issues related to authentication, chain of custody, expert testimony, procedural fairness, and evidence validation, while also evaluating the impact of emerging technologies, including artificial intelligence, blockchain, the Internet of Things, and deepfake detection on digital forensic practice. The findings indicate that reliable digital evidence requires standardized forensic procedures, scientifically validated investigative methods, and harmonized legal frameworks capable of addressing rapidly evolving cyber threats. Strengthening collaboration among forensic practitioners, legal professionals, researchers, and policymakers will be essential for improving evidence integrity, enhancing judicial confidence, and supporting effective cybercrime investigations. The review provides an integrated perspective that contributes to ongoing discussions on developing secure, transparent, and legally robust digital evidence management practices.
