In public administration, motivation refers to the justification and rationale behind decisions made by authorities. Traditionally viewed as a formal requirement to ensure legality and transparency, its significance extends beyond mere procedural compliance. Proper motivation in administrative acts not only fulfills legal requirements but also strengthens public trust and enhances administrative legitimacy. This article seeks to explore motivation as a fundamental component in the issuance of administrative acts, using a documentary review with a qualitative and legal hermeneutic approach. A well-articulated motivation promotes reflection and responsibility within the administration, encouraging officials to make carefully considered and well-supported decisions. This also aids judicial oversight and review of administrative acts, ensuring they are free from arbitrariness. Therefore, motivation should be viewed not only as a formal obligation but as a commitment to quality and ethics in public administration.
