He went into the legal history of Germany as a writer of amateur level one. About his youth little is known, a rhymed obituary, is reported in which, among other things, he was a begging Scholar wandering and choir students at Blaubeuren been true with the studied life data agree so little that its authenticity content must be questioned. According to the studies by Reinhard H. Seitz was Tengler noble descent, this fit his later career and pictorial representations with crests and noble clothes. After Tenglers own admission he was a young man, first clerk in the time associated with Bavaria-Landshut Heidenheim an der Brenz, where he spent before 1470, the purpose of a box recorder, so scribe of seigniorial Kastner to take over. follows the first major career move then from 1479 appointment as High Councillor Schreiber (Pronotarius) in Nördlingen. Although the contract was extended in 1483 for life with 100 florins annual salary, free accommodation and the perk "honest to hold two substitutes as Kantzleischreiber" he announced at the end of the same year at the position for unknown reasons. He felt, however, obliged the city to "service and support" of gratitude that Mayor and Aldermen "done out of any particular inclination to him and seynen children from Ergötzlichkeit ain Control" .
From 1485 it was then even Kastner in Heidenheim an der Brenz in, from about 1495 county judge and bailiff Graisbach at Donauwörth.

Among other things, the exchange of letters with his son Christopher, a professor of canon law at the University of Ingolstadt, one knows that Tengler with Ingolstadt scholars as the poetry Professer Jacob Locher (Philomusus), was connected. So far, the science was assumed that Tengler the laity mirror shortly before his death and wrote the (greatly expanded) New amateur mirror was not printed until after his death.Investigations on the occasion of the 500th Birth year of the law book but revealed that Ulrich Tengler lived until about 1521/22 and also responsible for the expansion of the new edition features. The laity mirror , also Layenspiegel or Laijen mirror , is an important legal point of early modern period. Tengler intended by him to teach Roman law to popular content in German. Under the title "Laijen mirror. of lawful regulations in Burger Lichen vnd embarrassing regiments.with allegation [s] vn [d] bewerungen gesatzen Inc geschribnen vnnd right " the right book was printed in 1509 for the first time.

The laity mirror experienced during the 16th Century an impressive 14 runs and had 70 years in use throughout Germany. Together with the conceptually related Klagspiegel of Conrad Heyden he formed the so-called popular literature on Roman Law in Germany. Complementing each other, the two works promoted the adoption of Roman law in the German legal practice probably more sustainable than any other magazine, served as a model for numerous other law books. Later gradually supplanted as the scholarly literature of Zasius and his school this literary genre. Tengler thought she had to also get involved in the persecution of witches. He criticized the lawyers to doubt the reality of witchcraft and makes them responsible for the extent and growth. Again and again it is assumed that he has contributed by his undeniable popularity in legal questions about this painful and saddest aberration of justice. But witch hunts are in the coverage area of the amateur level only intensified assignable after 1580 - ie after the main period of use of the lay level.
