This talk will review the current understanding of the magnetic configuration of filaments at the onset of their eruption as a coronal mass ejection, including both active region and quiet sun prominences. The evolution of the magnetic field will be discussed as inferred from multiwavelength observations that indicate the formation of a magnetic flux to be occurring in the days before the CME associated with active region filaments. In addition, spectroscopic data will be discussed in the context of learning more about the 3D magnetic structure that cannot be deduced from imagers alone.
