Divorce by Combat
In medieval Germany, husbands and wives could fight in a marital duel in order to legally settle their disputes.
Interestingly, the man had to fight in a hole with one of his arms tied behind his back. The woman was allowed to move freely within the arena but had to wear cloth containing weights. As for her weapon, she was usually given a sack filled with rocks. The man was provided with three clubs. However, if he touched the side of the hole during combat, he had to forfeit one of his clubs.
