Are there any Norse stories that feature trials to claim the throne?

Question

I’m writing a story where the main character is the heir to a throne but has to pass 3 trials to actually claim the throne as hers.

Are there any trials that the Norse used in similar cases?

Answer 1

Arguably, Norse mythology even has a god of trials, Forseti

The Æsir named Syn springs to mind. She guards the gates of Frigg's hall and issues trials so that only those worthy may enter. Her judgement is final.

The Voluspá, gives the account of the trials of Gullveig.
