During the webinar we will address some background information on federal liens, the origin of CERCLA liens and how they function, including when they arise, how they are recorded and enforced, procedural requirements, and what happens when they meet the competition. Issues will include lien priority in light of the competition for often limited monies, consensual liens, involuntary liens, and what is "circular priority."
