☰A series LLC captive uses a legal structure in which one limited liability company creates internal series, each with its own assets, liabilities, and business purpose, legally walled off from the others. Applied to captives, each series can operate as its own insurance program under a shared umbrella, an arrangement that resembles a cell captive built on LLC law rather than insurance-specific cell statutes.
The attraction is efficiency: one umbrella entity, multiple separated programs, lower cost per program. Not every domicile licenses the structure. Whether a series, a cell, or a standalone captive fits a given program is a structuring question your captive manager answers with legal counsel at the table.
