Opening a series under a Wyoming Statutory Trust (WST) offers a lot of flexibility, but because the WST is a distinct legal entity from a standard LLC, the naming conventions are governed by specific statutory requirements to ensure legal “separability.”

​In Wyoming, the naming process is generally handled within the trust’s own governing instrument rather than through separate filings with the Secretary of State for every individual series.

​1. The Statutory Requirement

​According to Wyoming law, the name of a specific series must be associated with the “Master” Statutory Trust. To maintain limited liability protections between different series (the “internal shield”), the name should be distinct.

  • The Master Name: Must include the words “Statutory Trust” or the abbreviations “ST” or “S.T.”
  • The Series Name: While the statutes are flexible, the best practice is to include the Master Trust’s name within the series name to provide clear notice to third parties.

​2. Common Naming Patterns

​Most practitioners use a “Master-Sub” naming convention. If your Master Trust is named “Blue Horizon Statutory Trust,” your series would typically be named as follows:

StyleExample
Formal/FullBlue Horizon Statutory Trust, Series A
Asset-BasedBlue Horizon Statutory Trust, 123 Maple St Series
NumberedBlue Horizon Statutory Trust, Series 01

3. The “Doing Business As” (DBA) Option

​If you find the full statutory name too clunky for branding or banking, you can file a Trade Name (DBA) for a specific series in Wyoming.

Example: > * Legal Name: Golden West Statutory Trust, Series 5

  • Registered Trade Name: “Golden West Rentals”

​4. Key Steps for Implementation

​Unlike a Series LLC in some other states, you do not usually file “Articles of Organization” for each series with the Wyoming Secretary of State. Instead:

  1. Amend the Governing Instrument: Execute an amendment or a “Series Designation” document internally that officially births the series and defines its name.
  2. Maintain Separate Records: Ensure all contracts, bank accounts, and titles for that series use the specific series name (e.g., “Blue Horizon Statutory Trust, Series A”).
  3. Public Notice: Ensure the Master Trust’s filed Certificate of Trust contains the required statutory language stating that the trust may have separate series with limited liability.

​A Critical Note on Clarity

​The most important rule is consistency. If you name a series “Series 101” in your internal records but sign a contract as “Series A,” you risk “piercing the veil” between the series. Always use the exact name established in your series designation document for all external transactions.

​How many different series are you planning to launch under this trust, and will they be holding different types of assets?
