He had three brothers, Alexander (II), a castellan of Körösszeg (present-day Cheresig, Romania); Demetrius Nekcsei, the influential Master of the treasury in the court of Charles I of Hungary, and Nicholas.
[1] Ladislaus first appears in contemporary records in 1280, when he already functioned as provost of the collegiate chapter of Titel (today in Serbia).
He and his brothers were granted the northeastern part of the lordship (Kecerkosztolány, Hanusfalva and the surrounding lands, present-day Kecerovce and Hanušovce nad Topľou, Slovakia).
[4] Sometime in July 1299, Ladislaus was made vice-chancellor of the royal court, replacing Anthony (although an authentic charter refers to him in this position already in January).
In that year, Andrew III confirmed the land division contract of the Lipóc branch in his royal charter, upon the request of Ladislaus and his kinship.
