He was raised in Germany, alongside his two sisters. However, in their adult lives, he is the only one who still resides there. Princess Alexandra has since moved to France and Princess Nathalie resides in Denmark.At present, he is unmarried and in a long-term relationship with former American model and children's book author-illustrator Carina Axelsson. If he should remain unmarried and childless at his death, the Sayn-Wittengenstein-Berleburg throne will pass to his uncle Hereditary Prince Robin zu Sayn-Wittgenstein-Berleburg or to his cousin, Prince Sebastian of Sayn-Wittgenstein-Berleburg. He and his sisters are not in succession for the Danish throne due to their grandfather stipulating that they must be raised in Denmark in order to have succession rights, however they are in succession distantly for the British throne as descendants of Queen Victoria.

He shares a birthday with Archduchess Zsófia Mária Tatjana Monika Erzsébet Katalin von Hasburg (Sophie Maria Tatiana Elisabeth Catherine).
