This study investigates the legal responsibilities of Land Deed Officials (Pejabat Pembuat Akta Tanah or PPAT) for sale and purchase deeds that are later annulled by court decisions. The role of PPAT is critical in ensuring legal certainty in land transactions, as their deeds serve as authentic evidence of the parties' legal actions and intentions. However, issues arise when a PPAT fails to exercise proper diligence, such as by not verifying the legal status of the land or the authority of the parties involved. This research focuses on Decision No. 3/Pdt.G/2023/PN Bna, where a PPAT issued deeds for the sale of inherited land that had not been formally transferred to the seller, resulting in the annulment of those deeds.
