Administrative Forfeiture is a method granted by the Omani legislator to administrative authority to collect the outstanding monies owed thereto from the debtors. It involves streamlined rules and procedures through which it can seize the debtor?s properties which are slod thereafter without having to resort to the court, unlike the case with judicial seizure. This study aims at clarifying the rules and procedures to be followed by the creditor administrative authority to impose and enforce attachment on the debtor?s properties, and to assess the Omani legislation with respect to its approach in this regard. Accordingly, this study is divided into three chapters besides the preliminary chapter, which clarified the nature of Administrative Forfeiture in terms of defining the concept and determining its legal nature. As for the first chapter, it touches upon the three pillars of Administrative Forfeiture, whilst the second chapter of the study is dedicated to the general procedures of Administrative Forfeiture, dealing with the introductions to Administrative Seizure and the general rules for seizure of transferables and real estate. As for the third chapter, it includes Administrative Seizure particular procedures, explaining the procedures for Administrative Forfeiture of transferables, as well as Administrative Seizure procedures of financial or commercial securities and real estate. The study presents in its conclusion a set of outcomes and recommendations, which we hope will improve in the legislative system.
