The notarial profession holds a strategic role as a public official entrusted with ensuring legal certainty and authenticity in civil transactions. However, notaries face a juridical dilemma when confronted with the obligation to report Suspicious Financial Transactions as mandated by Law No. 8 of 2010 on the Prevention and Eradication of Money Laundering (Anti-Money Laundering Law). On one hand, notaries are bound by the principle of professional confidentiality as stipulated in the Notarial Act and the professional code of ethics, while on the other hand, they are required to report Suspicious Financial Transactions to the Financial Transaction Reports and Analysis Center (PPATK) as part of the Anti-Money Laundering and Counter-Terrorism Financing (AML/CTF) regime. This study employs a normative juridical method with a literature-based approach to analyze the legal consequences of non-compliance with reporting obligations and the potential legal protection available to reporting notaries. The findings indicate that failure to comply with reporting duties may result in administrative sanctions, criminal liability through the doctrine of participation, and ethical sanctions from professional organizations. Nevertheless, the Anti-Money Laundering Law grants legal immunity to notaries who report in good faith, thereby ensuring that professional reporting based on rational indicators cannot serve as grounds for either criminal or civil claims. Such immunity functions as a justification that removes the unlawful nature of the reporting act. Accordingly, this study underscores the importance of maintaining a balance between fulfilling legal obligations and safeguarding the notarial profession in the context of notaries’ responsibility for preventing financial crimes.
