ABSTRAK
Penelitian ini membahas tentang pembeli lelang eksekusi PUPN yang mengalami kerugian akibat objek lelang yang dibelinya fiktif, padahal objek lelang merupakan unsur pokok dari lelang. Selain itu objek lelang dalam kasus ini merupakan barang jaminan atas kredit macet dari bank pemerintah (BRI) yang pengurusan piutangnya diserahkan kepada PUPN/KPKNL, idealnya objek lelang tersebut telah dipastikan keberadaannya baik oleh pihak Bank maupun PUPN sebelum dijadikan objek lelang. Penelitian ini adalah penelitian yuridis normatif dengan preskriptif. Dari penelitian ini penulis menyimpulkan bahwa saat ini perlindungan hukum bagi pembeli lelang masih didasarkan pada putusan pengadilan secara kasus per kasus. Penulis menyarankan bagi para calon pembeli lelang untuk berhati-hati saat memeriksa keabsahan dokumen serta kondisi fisik objek lelang yang diminati, berkenaan dengan kasus ini disarankan bagi bank-bank di Indonesia dan PUPN untuk menjalankan tugas pokok dan fungsinya dengan sebaik-baiknya agar tidak terjadi kasus seperti ini di kemudian hari. Diperlukan penyempurnaan peraturan perundangan di bidang lelang khususnya mengenai perlindungan hukum bagi pembeli lelang sebagai pihak yang mempunyai itikad baik.
