Penentuan Subjek Hukum dalam Sertipikat Hak Milik yang Berasal dari Tanah Ulayat Kaum (Studi terhadap Tanah Ulayat Kaum Suku Tanjuang Kecamatan Lubuk Begalung Kota Padang)

Ulayat land is a form of communal land tenure in Minangkabau customary law. In land registration practice, communal ulayat land may be registered as ownership rights by naming certain individuals as rights holders. This raises questions about the legal status of certified ulayat land, the consequences of omitting the clan's name from the certificate, and legal certainty for members not named in it. Using normative legal research with statutory, conceptual, and case approaches and qualitative analysis, this study examines these issues from national law and Minangkabau customary law perspectives. The results show that the Tanjung Clan's ulayat land, registered under Certificate of Ownership No. 329 of 1995, acquired ownership status under the regulations of the time, while the clan's communal relationship with the land remains recognized under customary law. The designation "mamak kepala waris" does not convert ownership rights into ulayat rights, since the clan leader's position differs from that of a registered rights holder. Administrative recognition rests on registered names, so unregistered members lack equal status, though their customary relationship with the land does not automatically cease. Clarifying the relationship among rights holders, the clan, and members is needed to ensure legal certainty.
