[ABSTRAK Terbukanya suatu pewarisan adalah karena kematian. Sehingga, dengan terbukanyapewarisan maka di dalam KUHPerdata telah ditentukan siapa-siapa yang akanmenjadi ahli waris. Namun, adanya perbedaan penafsiran, suatu warisan tidakdidapatkan apabila di dalam suatu ikatan perkawinan telah dilaksanakan dengan suatuperjanjian perkawinan. Sehingga timbul permasalahan yaitu bagaimana pengaruhperjanjian perkawinan pisah harta antara suami dan istrinya terhadap hak mewarisserta bagaimana kedudukan hukum mewaris suami dan adik pewaris terkait sebagaiahli waris yang ditinjau dalam KUHPerdata. Terhadap permasalahan tersebut,dilakukan penelitian untuk menemukan titik terang akan siapa yang akan berhakmenjadi ahli waris. Selanjutnya, penyusunan tesis ini disusun dengan metodepenelitian hukum normatif, untuk mendapatkan hasil penelitian yang bersifat analisiskualitatif yaitu dengan menelaah data yang diperoleh. Akhirnya, sampailah pada hasilpenelitian bahwa suatu perjanjian perkawinan mengatur pemisahan harta kekayaanselama perkawinan, dengan putusnya perkawinan akibat kematian seseorang terhadapharta kekayaan, akan adanya pewarisan dalam bentuk perpindahan kekayaan dandalam pewarisanpun telah ditentukan siapa yang menjadi ahli waris, sehingga suatuperjanjian perkawinan tidak dapat menutup hak mewaris seorang suami. Kedudukanhukum seorang suami dan adik pewaris sebagai ahli waris telah ditentukan denganpenggolongan ahli waris yang mana golongan ahli waris terdekat menutup golonganahli waris terjauh. Dengan demikian, karena masih adanya suami, harta peninggalanpewaris, haruslah jatuh pada golongan pertama. Disarankan bagi Notaris untukmemberi penjelasan bila ingin membuat perjanjian perkawinan.
