Badoer was born at Venice on 5 September 1512, the son of Piero di Albertino.
[1] He belonged to a minor branch of the Badoer family and was the second of three sons.
His vast inheritance was divided between his widow's two brothers and his two sisters' husbands.
The division took a decade to resolve, but left Badoer in possession of 460 acres in the Polesine.
In 1556, he hired Andrea Palladio to design for him a new house at Fratta.
