He held the dignity of Ban of Macsó (Mačva) (1402–1403 and 1410–1418), as well as župan (ispán, count) of Baranya, Bodrog, Srijem, Vukovar and Tolna in the associated kingdoms Hungary and Croatia.

First mentioned in 1395 in a document issued by Nitra Cathedral chapter house, Ladislaus was the owner of Lack estate at the village of Gamás in Somogy County (southwestern Hungary).

[6][7] Ladislaus was granted amnesty upon the intervention of Nicholas Garai and the payment of 12,000 golden florins to the royal treasury.

[5] Besides their dignity in the royal court, the brothers served as župan/župan (ispán, count) of Baranya, Bodrog, Srijem, Tolna and Vukovar County.

[citation needed] Ladislaus was last mentioned in documents in February 1418 (his brother Emeric appears as sole Ban of Macsó in contemporary records already in April 1418).
