Like SyndiCat, if you too are struggling to differentiate between these twins, read on!
Delaware gave us the Series LLC – a protected structure that promised flexibility and compartmentalization. Then it went further and gave us the registered structure. Sounds like twins from the same LLC family, but with very different ambitions – one that stays quietly protected, and the other registers for all to see.
Let’s outline them both:
Protected Series: The Invisible Twin
- Exists under the umbrella of a master LLC.
- Doesn’t file separately with the state (so no file number).
- Keeps its assets, liabilities, and members separate internally (through the operating agreement) and this is where the protection is.
- Not individually recognized by the Delaware Division of Corporations.
- Pros: Cheaper, simpler, private.
- Cons: Less recognition by third parties like some other states.
Think of it as the “internal ledger” approach to a Master-Series structure – protected in principle and invisible in public.
Registered Series: The Visible Twin
- Created by filing a Certificate of Registered Series with the DE Division of Corporations.
- Gets its own state-issued name and certificate (like a mini-LLC under the master).
- Statutorily distinct from the master and its other series.
- Pros: Legal clarity, better acceptance with banks, investors and other states.
- Cons: Additional filing fees and admin work.
So this one gets its own seat at the state’s table through a legal presence, but (literally) pays for it.
It may be worthwhile to point out that
Registered Series = Protected Series + further State registationAnd since registration comes with the additional costs and work, it is important to go “registered” only if you really need to.
Why the Difference Matters (and When to Use Which)
| Scenario | Recommended | Why |
|---|---|---|
| Internal fund tracking or SPV sub-pools | Protected Series | Low-cost and internal separation is enough |
| Multi-investor syndicate or third-party dealing | Registered Series | Provides external recognition and credibility |
| Bank account or financing setup | Registered Series | Banks often require state-recognized entities |
| Layered asset ownership (like real estate series) | Registered Series | Easier title tracking and external contracts |
Quick Example
Suppose your (master) Delaware LLC, MainStreet Ventures LLC, runs two separate deals.
- If all LPs trust the master-level protection & there are no complex funding / ownership structures, you can create two protected series – MainStreet Ventures LLC – Series A and MainStreet Ventures LLC – Series B. Else
- You can register both (the above) separately with DE (and generate their respective DE file numbers) for a cleaner separation and even do business in various non-DE states that do not recognize DE protected series, and so on.
Same flexibility. Different footprint.
Takeaway
Protected vs Registered is not about which is better – it’s about what you needs are.
In the eyes of the parent (Delaware), both twins (protected & registered) are legit. But in the eyes of other states, your banks, auditors, or even LPs, one may shine brighter.
