Washington LLC Agreement: Free Operating Agreement Templates

| Updated October 14, 2026

A Washington LLC operating agreement is the internal contract that governs how a limited liability company runs. Washington uniquely lets it be oral, implied, or written under RCW 25.15.006(8). Without one, default rules in RCW 25.15 take over, and they rarely match what most owners actually want.

Does a Washington LLC Need an Operating Agreement?

A separate written agreement is not a statutory condition of forming the LLC. Washington’s statute expressly contemplates situations where a limited liability company agreement “does not exist,” and its definition allows the agreement to be oral, implied, in a record, or a combination of those forms. Washington Secretary of State guidance nevertheless tells LLCs to create an operating agreement as their internal governance document.

What the state actually files is the Certificate of Formation. The operating agreement stays with the business and is not recorded by the Secretary of State. The current state filing fee for a domestic LLC Certificate of Formation is $180, with an additional processing fee for online filing. See the Washington Secretary of State’s domestic LLC filing instructions.

Chapter 25.15 contains no requirement that the LLC agreement be notarized, and the statutory definition does not require a particular signing form.

Washington LLC Default Rules Worth Replacing in Writing

Washington’s defaults are especially important where ownership percentages and decision-making power are not meant to be the same thing. For the state’s detailed approval rules, see Washington’s member voting statute, RCW 25.15.121.

This combination makes the written agreement particularly useful in Washington. A 70 percent investor, for example, does not automatically receive 70 percent of the voting power simply because of the investment percentage, and a departing member does not automatically trigger a statutory buyout.
