Nikiforovec is mentioned several times in the Land Inventory Brebion. A certain Vladimir donated a field in Nikiforovec to the Monastery of the Holy Virgin in Htětovo for the right to have a grave (288, art. 31: Niva u Nikiforovci što dade Vladimirь za grobь, nizь Sopotnikovu nivu I do Kraseve ōd Želina). The Land Inventory Brebion contains also evidence on a field not far from Nikiforovec above Sredorek, which was bought by the monastery from Gjuroj for a horse (288, art. 38: Niva u Nikiforovci nad Srědorěkomь kuplena ōtь Gjuroja za konь). The grandson of Krasev, a certain Dmitr from Želino, donated the field Trstěnica in Nikiforovec with the meadow near to the field Vladimir to the Monastery of the Holy Virgin in Htětovo for the right have a grave and for his tonsure as monk (293, art. 53: Niva Trьstěnica u Nikiforov᾿ci i s livadomь blizь Vladimirove nive, što jestь dalь Krasevь unukь, Dmitrь ōtь Želina, za grobь i za postrigь). A certain Strezo donated his field to the Monastery of the Holy Virgin in Htětovo, and the Land Inventory Brebion gives a careful delimitation of its boundaries (295, art. 59: Niva što priloži Strězo u Nikiforov᾿ci ōd Topila do Klěna I do Sopotnikove nive I do popa Vladove kuplenice, i uz livadu crьkvu i do kneževe nive). The Land Inventory Brebion contains evidence on the acquisition of a field in Nikiforovec, which was bought from Theodor and his daughter Jelena to some extent by the abbot (hegumen) Theoktist and the rest by the bishop Ignatij (296, art. 64: Niva u Nikiforovci, uzь crьkvnu nivu što kupi igumьnь Theōktistь u Theōdore i u čtere Jelene za 10 perperь, a dokupi piskopь Ignatije i zapisa). According to the Brebion an Oikonomos of the Monastery Mathei had bought an estate near Nikiforovec from Mišat, who came from the village of Mel (296, art. 67: I dva komata nive što kupi ikonomь Mathei u Mišata ōd Mela, za 12 perper, jedna…, a druga u Nikiforovci do Budriga i do puti prěmo Klenu i do Gumništ). The Emperor Stefan Uroš IV Dušan donated the village of Mlačice to the Monastery of Hilandar. The General Charter describes the boundaries of the village of Mlačice with its land and mentions Nikiforec (Mlačice sь zemlomь, što je dalь svety kralь; a megja zemli toi ōdь Nikiforca kako grede putь na ōpogorь prězь livadu u Kraljevu Pekь i u Bivolь Brodь).
