The Danish brothers, the owners of football analysis company Football Radar, agreed a deal with outgoing Alan Hardy, who put the Meadow Lane Club up for sale in early 2019.
The Magpies were relegated to The National League for the first time in their history back in May.
After finalising the takeover, the new owners said: “We are delighted that the deal has been completed, and that the uncertainty about the Club’s future has come to an end.
“We can now all shift our focus towards the exciting new football season which is just around the corner.
“Why Notts County? It goes without saying that Notts County are a big Club with a proud history, and its status as the world's oldest professional football club is something that we, and anyone else who loves football, find absolutely compelling.
“The Club's results in recent years have not lived up to the high expectations, but the fans have continued to support their team wholeheartedly.
“In our view, the fans are the foundation of any successful football club.
“The passion and loyalty that the Notts County fans demonstrate is truly admirable, and of essential importance to the Club's future.
“We look forward to getting to know the fans better and to working with them to take Notts County forward”.
