[1] After the death of his father, King Ladislaus IV of Hungary confirmed Stephen as the owner of the ruined castles Lenti and Alsólendva (today Lendava, Slovenia) and the surrounding villages in 1278.
[2] Similarly to other members of his kindred, Stephen was a loyal supporter of Andrew III since his coronation took place on 23 July 1290.
When Andrew invaded Austria, forcing Duke Albert to withdraw his garrisons from the Hungarian towns and fortresses at the western border, Stephen participated in the siege of Pettau (today Ptuj in Slovenia), where his horse was stabbed.
Stephen was able to survive and escape from the battlefield due to Peter Gosztolyai, one of his bannermen's self-sacrificing, who handed over his horse to his lord.
On 14 July 1291, Andrew donated land domains to the soldier's widow and orphans as compensation at the request of Stephen Hahót.
