Kondisi Indonesia yang saat ini telah menjadi salah satu negara anggota New York Convention on The Recognition and Enforcement of Foreign Arbitral Awards 1958 (New York Convention 1958) membuka peluang bagi putusan arbitrase internasional untuk dapat diakui dan dilaksanakan di wilayah hukum Republik Indonesia. Dalam hal ini klasifikasi suatu putusan arbitrase, apakah merupakan putusan arbitrase internasional atau putusan arbitrase nasional, menjadi penting karena berpengaruh terhadap kewenangan pengadilan terhadap perkara arbitrase internasional. Namun pada praktiknya dijumpai adanya perbedaan persepsi mengenai putusan arbitrase internasional menurut Undang-Undang Nomor 30 Tahun 1999 tentang Arbitrase dan Alternatif Penyelesaian Sengketa (Undang-Undang Arbitrase) dan konvensi internasional. Dengan menggunakan pendekatan yuridis normatif skripsi ini akan memberikan analisis mengenai aspek-aspek Hukum Perdata Internasional serta analisis mengenai pertimbangan hukum para hakim di Indonesia dalam pengklasifikasian putusan arbitrase internasional pada perkara Nomor 144/K/Pdt/2012 dan perkara Nomor 175/PDT/2018/PT.DKI. Selain itu juga ditemukan keperluan atas keselarasan pengaturan mengenai putusan arbitrase internasional dalam Undang-Undang Arbitrase dan konvensi-konvensi internasional demi mencapai kepastian hukum.
