He grew up with his two years younger brother Otto Arenfeldt Reedtz on the family manor house Palsgaard in East Jutland.

[3] He passed his legal office examination with a first grade on 11 April 1823 and then continued his studies in history, international law and languages.

He prepared a dissertation on Denmark's treaties with foreign powers from the time of Canute the Great in 1026 to the end of the 18th century.

In 1842 he resigned his position because he felt that King Christian VIII had bypassed him, as he had himself contacted Sweden in the matter of the abolishment of the Sound Dues, a subject Reedtz as official had worked on for a long time.

When the brother in 1846 moved with his family to the estate Tamdrup Bisgaard, which he had bought, Reedtz continued as sole owner of Palsgaard.
