Identification and development of forensic accounting as an organization's essential intangible asset has been traced as an immense vital essence that can influence corporate governance maturity. This paper attempts to integrate relevant empirical research and literature to extend the intended potentials of forensic accounting on corporate governance maturity particularly in public listed companies in Oman. Moreover, this paper will identify the role of forensic accounting as preventive measure rather than a detective control which is at present widely understood. The paper also proposes that internal audit poses a mediating role between forensic accounting and corporate governance maturity by linking professional theory and agency theory in its relationship. Since the existing literature provides less evidence that attempt to observe the influence of forensic accounting on corporate governance maturity, this paper offers and calls a promising proposition for future research.
