In 1319, the Waldgraves of Kyrburg raised a claim to the jurisdiction in Buborn, which also stretched out to the surrounding villages. At the Kyrburger Hof, an estate held by the Waldgraves of Kyrburg in the Buborn area, the Waldgraves held court (they called it the "Eicher Gericht"). No sooner had Buborn ended up in the Waldgraves’ hands than a whole series of surrounding villages subject to the "Hochgericht auf der Heide" were pledged by Johann von Dhaun to the County of Sponheim-Starkenburg. It is known, however, that the village itself was pledged at this time as "Hof in Bopporn" ("Hof" means “estate”) to Reinfried von Reipoltskirchen. The exact date of the deed is unknown. Nevertheless, Buborn was in his hands in 1408 when Waldgrave Gerhard V died. The pledge was further passed on in 1431 to Friedrich von Rüdesheim, Reinfried von Reipoltskirchen's son-in-law. Shortly thereafter, the Waldgraves must have redeemed the pledge, for in 1448, Waldgrave and Rhinegrave Gottfried zu Dhaun sold the village, along with others in the Grumbacher Tal (dale), while reserving the right to buy them back, to Count Palatine Stephan of Zweibrücken. The Waldgraves exercised this right in 1477. It is likely that in the early 16th century, Buborn belonged to the Waldgraves and Rhinegraves of Grumbach. In 1515, Buborn was firmly in this county's hands, and the Waldgraves and Rhinegraves of Grumbach thereby also held the jurisdiction. From this year comes a "Weistum" that states that both jurisdiction (that is, the court's power) and the lordship were held not by Kyrburg, but rather by "Grombach" (a "Weistum" – cognate with English "wisdom" – was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times).
