Hiltbold von Werstein was the son of a baronial family whose seat was located in the upper Neckar valley.
He did, however, get closer to the Habsburg party and received an assurance of assistance from Duke Leopold, documented in a treaty from the 30 June 1319.
A document from 15 November 1323 reports the negotiations about a border dispute between Appenzell and Hundwil for which Hiltbold acted as mediator.
It is also recorded that on 27 November 1325, Leopold of Austria arranged a settlement for a dispute with the family of Toggenburg in which the abbot was implicated against his will.
He was compelled by his old age to entrust his seal with a conventual, a ministerialis and a citizen, who took over his administerial functions by the end of 1325 or the beginning of 1326.
