Terminology varies by jurisdiction. Statutes use terms such as protected cell, incorporated cell, segregated account or series, and they are not interchangeable; confirm the exact legal form in the domicile you are considering.
| Factor | Unincorporated cell | Incorporated cell | Rent-a-captive | Standalone captive |
|---|
| Separate legal entity | No — part of the sponsor | Yes, where the statute provides | No | Yes |
| Basis of separation | Statute and cell agreement | Statute and separate entity | Contract and accounting | Separate company |
| Your control | Within sponsor rules | More, through the cell’s own board | Within sponsor rules | Full |
| Leaving | Cell termination needs approval | Can be more portable; check the law | Contractual exit | Your decision, subject to run-off |
Counsel familiar with the domicile's cell statute should review the cell agreement; ask the sponsor for its own financial statements and how it handles a failing cell.
