Articles 83 and 84 of the Dahir of 12 August 1913 on land registration establish a key mechanism for protecting real rights created or altered during the land registration process, while ensuring their extinguishment through the final registration decision. This framework seeks to strike a delicate balance between legal certainty and transactional fluidity, reflecting the duality between the traditional Melk ownership system and the modern scheme inspired by the Torrens model. However, the coexistence of these provisions raises practical and interpretative uncertainties regarding their actual effectiveness: whereas Article 83 provides for the publication of a corrective notice in the Official Bulletin, Article 84 determines chronological priority through registration in the opposition register. Regulated by Law No. 14‑07, these formalities- based on authentic deeds and the payment of land registry fees- aim to guarantee both the enforceability and continuity of rights up to final registration. Nevertheless, procedural shortcomings relating to time limits and the autonomy of applicants highlight the need for reform to strengthen land security.
