Does Washington Allow Series LLCs?
Washington does not currently have a Series LLC statute. You cannot form a Series LLC directly in Washington.
Business owners with a Washington base who want Series LLC-like liability separation typically consider two options: (1) forming a Series LLC in a state that authorizes them — most commonly Wyoming, Delaware, or Texas — and then registering as a foreign LLC in Washington; or (2) forming separate standard LLCs for each asset or venture in Washington, which achieves liability separation at a higher per-entity filing cost.
Note: Even if you form a Series LLC in another state, Washingtoncourts may not fully recognize the liability separation between series for activities conducted within Washington. Consult a Washington-licensed attorney before choosing this structure.
What Are the Alternatives in Washington?
- Multiple standard LLCs — the most legally certain approach in Washington; each asset or venture has its own filing, its own liability shield, and its own tax identity
- Holding company structure — form a parent LLC that owns subsidiary LLCs, keeping assets in separate entities while centralizing management
- Foreign Series LLC — form a Series LLC in Wyoming or Delaware, register it as a foreign LLC in Washington, and conduct business here — but note that Washington's recognition of the inter-series liability shield is untested

Washington Series LLC — FAQs
No. Washington does not currently have a Series LLC statute. You cannot form a Series LLC directly in Washington. Business owners who want Series LLC-like liability separation must either form a Series LLC in an authorizing state (such as Wyoming, Delaware, or Texas) or use separate standard LLCs for each asset.
A Series LLC is a master LLC with multiple legally separate "series," each holding its own assets and liabilities. In states that authorize them, debts and claims against one series cannot reach the assets of another. They are popular with real estate investors and multi-business owners.
Yes — you can form a Series LLC in Wyoming or Delaware and register it as a foreign LLC in Washington. However, Washington courts have not confirmed that they will respect the inter-series liability separation for activities conducted within Washington. This creates legal uncertainty that a standard multi-LLC structure avoids.
The most legally certain alternative in Washington is forming a separate standard LLC for each asset or venture. Another option is a holding company structure — a parent LLC that owns subsidiary LLCs — which achieves asset separation with cleaner legal clarity. LLC Attorney can help you choose and implement the right structure.
