Expanding Your Delaware Series LLC: How to Add a Protected Series
Delaware pioneered the Series LLC, a unique business structure designed for entrepreneurs who operate multiple independent businesses or assets under a single legal umbrella. In a Delaware Series LLC, you can create separate "cells" or "series"—each with its own assets, members, and management—without the need to form entirely new legal entities.
A common question for business owners using this structure is: How do I add a new series once the initial LLC is formed? This guide explains the process for adding a Protected Series to your Delaware LLC and the steps required to maintain your liability protection.
What is a Protected Series LLC?
Under Delaware law, a Protected Series is an internal cell of a larger LLC. Each series:
* Can conduct its own business activities.
* Can enter into contracts, sue, and be sued in its own name.
* Has its own assets that are legally shielded from the debts and liabilities of the other series or the overall LLC.
* Can have its own specific members and managers.
The Internal Creation Process
One of the primary advantages of the Delaware Protected Series is efficiency. Unlike traditional business formations, adding a Protected Series does not require a filing with the Delaware Division of Corporations. Instead, the process is handled internally.
1. Amend the Operating Agreement
The master Operating Agreement of your Series LLC is the governing document that allows for the creation of new series. To add a series, you must amend this agreement to:
* Identify the name of the new series (e.g., "Main Street Ventures, LLC – Series A").
* Define the specific purpose and assets of the series.
* Outline the management structure and member interests for that specific series.
2. Adopt a Formal Resolution
Even though the state doesn't require a filing, you must document the creation of the series through a formal member or manager resolution. This document should state that the series has been created in accordance with the Operating Agreement. While internal, this resolution is often required by banks or lenders to prove the series exists and has the authority to conduct business.
Maintaining the Liability Shield
The legal protection offered by a Series LLC is only as strong as your internal record-keeping. To ensure the "protected" status of your new series is maintained, you must respect the separation of each cell.
Obtain a Separate EIN
While not strictly required by every state for tax purposes, obtaining a separate Employer Identification Number (EIN) from the IRS for each series is a best practice. It reinforces the legal separation of the series and is often necessary for the next critical step.
Open a Dedicated Bank Account
Each series should have its own bank account. Commingling funds between series or with the master LLC can "pierce the corporate veil," potentially exposing the assets of one series to the liabilities of another.
Keep Distinct Records
Maintain separate accounting books and records for each series. Document all inter-series transactions (if any) as formal business deals.
Branding and Public Record
Because a Protected Series doesn't have a separate filing with the state, it may not appear in public database searches. To provide transparency and establish a public record for your new series, many business owners file a Fictitious Name Statement (DBA) in the jurisdictions where the series operates. This is especially helpful for opening bank accounts and establishing brand identity.
