According to the Illuminated Chronicle, Béla "introduced the same form of addressing petitions as was customary in the Roman and imperial court", which suggests that the Royal Chancery began functioning as a separate office during his reign.
Menurut Kronik iluminasi, Béla "memperkenalkan bentuk yang sama dalam menangani petisi seperti biasa di istana Romawi dan kekaisaran", yang menunjukkan arsip umum kerajaan mulai berfungsi sebagai kantor terpisah di masa pemerintahannya.
