Asas kebebasan berkontrak menyebabkan timbulnya beraneka ragam perjanjian, salah satunya perjanjian nominee. Terdapat 2 (dua) pihak berdasarkan perjanjian nominee yaitu nominee dan beneficiary sehingga memunculkan suatu pertanyaan mengenai status kepemilikan obyek yang diikat dengan perjanjian nominee dan permasalahan mengenai kewenangan dan tanggung jawab notaris terhadap obyek perjanjian nominee yang dimasukan dalam akta wasiat karena berdasarkan peraturan perundang-undangan perjanjian nominee tidak diperkenankan. Metode penelitian yang digunakan yaitu metode yuridis normatif dengan tipe deskriptif analitis. Berdasarkan hasil penelitian diperoleh yaitu, pertama status kepemilikan obyek yang diikat dengan perjanjian nominee yaitu milik pihak yang tercatat secara legal (nominee) sepanjang belum ada putusan pengadilan yang membatalkannya. Kedua, yaitu Notaris bertanggungjawab terhadap obyek perjanjian nominee yang dimasukan dalam akta wasiat sehingga dapat dimintakan pertanggungjawaban secara administrasi, perdata maupun pidana, oleh karena itu peneliti menyarankan notaris memberikan penyuluhan hukum berdasarkan Pasal 15 ayat (2) huruf e Undang-Undang No. 2 Tahun 2014 (UUJNP) dan apabila client memaksa obyek perjanjian nominee dimasukan dalam akta wasiat, maka notaris menolak dengan didasarkan Pasal 16 ayat (1) huruf e UUJNP.
