Retro Date Gap
A period of time between a prior policy's retroactive date and the current policy's retroactive date during which no coverage exists for professional acts. Retro date gaps most commonly occur when a law firm switches carriers and the new carrier sets a retroactive date at the new policy's inception rather than matching the prior carrier's retroactive date. Any malpractice claim arising from work performed during the gap period would not be covered by either the old or new policy. Avoiding a retro date gap is one of the most critical considerations when changing malpractice carriers, and firms should negotiate to maintain their existing retroactive date or purchase tail or nose coverage to close the gap.
