Washington LLC governance: a membership interest exposed from three directions, and the agreement that locks it down

A Washington membership interest is exposed on three sides at once, and most owners never see two of them. It is freely transferable by default, so the economic rights can leave without anyone’s consent. It is community property if it was acquired during the marriage, so a divorce can split it. And it sits under a charging order a creditor can foreclose, as the protection page explains. Any one of those would make the operating agreement worth drafting. Together they make it the load-bearing document it is, because the Washington statute closes none of these gaps on its own.

Washington runs its own LLC act, not the national uniform act, so its rules do not track the other pages on this site. This page covers what that act leaves open, and the one thing it lets you do that surprises people: eliminate fiduciary duties almost entirely. The general default mechanics are on the site’s default rules guide; the focus here is on the interest itself, because in Washington the interest is the thing at risk.

The interest that walks out the door

Start with transferability, because the Washington default is more permissive than owners expect.

By default a Washington membership interest is freely transferable, and only the operating agreement stops the economic rights from moving without consent.

Under RCW 25.15.251, a member’s transferable interest, the right to distributions, can be assigned without the other members’ consent. What does not transfer by default is management: the assignee gets the economic rights, not a vote or a seat. That split is the same one that makes the charging order work, and it cuts both ways. It means a creditor or an ex-spouse who ends up with the interest gets money, not control, which is some comfort. But it also means the economic value of the company can be handed to a stranger unless the operating agreement restricts transfers, and a silent agreement leaves that door open. The leaving an LLC guide covers why transfer and exit provisions are where a silent agreement turns into a fight.

The interest a divorce can split

Now the side almost no DIY operating agreement addresses, and the one Washington practitioners flag most.

A Washington membership interest acquired during marriage is community property, so a divorce can hand an ex-spouse half of it unless the documents say otherwise.

Washington is a community-property state, and under RCW 26.16 property acquired during the marriage, a membership interest included, is presumptively community property owned by both spouses even when only one is named as the member. On divorce, the community is divided, and a membership interest with no buy-sell or valuation provision can force a company toward a fire sale to cash out the departing spouse’s half. This is not a creditor problem or a tax problem; it is a governance problem hiding in family law, and it is invisible until the marriage ends. The operating agreement is where a Washington LLC handles it, through spousal-consent provisions, a buyout mechanism, and an agreed valuation method, so that a divorce transfers value on defined terms instead of through a forced sale. A separate-property analysis borrowed from another state misses this entirely.

The duties you can delete

Washington also sits at the permissive end on fiduciary duties, and this is where it looks like Arizona rather than Pennsylvania.

A Washington operating agreement may eliminate the duty of loyalty and the duty of care, keeping only good faith and a bar on intentional misconduct.

RCW 25.15.038 makes loyalty and care the only fiduciary duties a member or manager owes, and it lets the agreement modify, restrict, or eliminate them, provided it does not waive the duty to avoid intentional misconduct and knowing violations of law, the bar on improper distributions, or the implied duty of good faith and fair dealing. That is close to Delaware-style freedom of contract, and it is the same permissive posture Arizona takes, not Pennsylvania’s non-waivable floor. So a Washington manager can be released by agreement from most of the fiduciary framework, and a passive investor keeps only the thin floor of good faith, no intentional wrongdoing, and information rights that the agreement may not unreasonably restrict under RCW 25.15.018. An investor signing a Washington operating agreement should read the duty-waiver section as carefully as the economics, because the statute lets that section do a great deal.

The defaults behind all three

For everything the agreement does not address, the statute fills in, and its defaults are the ones every owner should want to change.

Stay silent and Washington splits distributions equally by headcount, votes per capita, and leaves the interest transferable, none of which most companies intend.

Under RCW 25.15.206, distributions before dissolution are shared in equal shares regardless of contribution, and voting defaults to per capita, so a member who funded most of the company and one who funded little share and vote evenly unless the agreement says otherwise. Washington also recognizes an oral or implied operating agreement, so a handshake can count, but reconstructing an unwritten deal from conduct is a poor substitute for a signed document, especially when the interest is exposed on three fronts. The lesson pulls together everything above: in Washington the operating agreement is not where you fine-tune a good default, it is where you close the transfer gap, the divorce gap, and the duty question that the statute leaves wide open.

The bottom line

A Washington membership interest is exposed from three directions at once, and the operating agreement is the only instrument that addresses all of them.

It is freely transferable by default under RCW 25.15.251, so transfer restrictions are what keep the economic interest from moving without consent.

It is community property if acquired during marriage under RCW 26.16, so a divorce can split it and a silent agreement can force a fire sale, which buy-sell and spousal-consent provisions prevent.

Fiduciary duties can be eliminated under RCW 25.15.038, leaving only good faith and a bar on intentional misconduct, the same permissive posture as Arizona and the opposite of Pennsylvania.

The distribution default is equal shares and voting is per capita under RCW 25.15.206, and an oral agreement counts, so the written document carries the deal, the duties, and the defenses.

What this page does not cover

This page is about the rules that run your company from the inside and the agreement that protects the interest. How outside creditors reach a member’s interest, the foreclosable charging order, and the county-median homestead are on the protection page. Where the entity lives, the missing series LLC, and the high transfer tax on entity sales are on the structure and cost page. Fees, the anniversary-month annual report, and the B&O tax are on the filing page.
