In the marriage contract, which was signed two days later on 17 July, the Emperor made the exceptional stipulation that Maria Anna would not renounce her rights over the Habsburg inheritance ("Erbverzicht") as was customary for Austrian Archduchesses when they married foreign princes; this was made probably by Ferdinand II with the intention to secure the rights of his eldest daughter in the case of the extinction of his male descendants. As a dowry, Maria Anna received the amount of 250,000 florins secured from Wasserburg Castle and the districts of Kraiburg and Neumarkt. As a widow's seat she received Trausnitz Castle in Landshut.
