if it's an irregularity (I'm assuming there are legitimate cases for two people to claim the same children, as with - say - divorced or separated parents) then eventually one or both of the people will get audited, and be asked to pay missing taxes and/or penalties.

A lien is a claim against the value of property, such as a house or a car. The property cannot legally be sold or transferred without settling the lien.
