The ritual was actually quite simple—a carved rune on both the keeper of the tether and the bound, followed by a few lines of Latin. Then, theoretically, a chain would manifest on the physical plane, made invisible with another spell should the husband want to keep the tether undetectable.

The tether could only be removed by the keeper.
