Washington requires all-party consent: everyone must agree before a private conversation is recorded.
Washington law is satisfied by a clear announcement at the start of the call. Use an announced, dated archive so the recording is lawful and usable.
Recommended: an announced, dated archive of your own line.

Short answer: in Washington State, you need the consent of everyone on a private call before you record it. Washington is an all-party consent state under its Privacy Act, and a clear, spoken announcement at the start of the call is generally enough to satisfy that requirement — you do not need a written agreement or a formal exchange, just a genuine, obtained consent from every participant.
What all-party consent means in Washington
Wash. Rev. Code § 9.73.030, part of the Washington Privacy Act, makes it “unlawful for any individual, partnership, corporation, association, or the state of Washington, its agencies, and political subdivisions to intercept, or record any: (a) Private communication... without first obtaining the consent of all the participants in the communication.” That is a direct, unambiguous all-party rule — there is no participant exception the way there is in one-party states, and no split by medium the way there is in Nevada. If the call or conversation is private and you have not obtained consent from every person on it, recording it violates the statute. The good news for anyone trying to comply is that Washington courts have long treated a clear announcement at the outset of a call — “this call is being recorded” — as sufficient to establish that consent, provided the other party continues the conversation after hearing it.
The penalties
A violation of the Washington Privacy Act can be charged as a gross misdemeanor — a serious offense, though notably lighter than the felony-level exposure parents face in states like New Hampshire or Pennsylvania. On top of the criminal exposure, the Act also creates a civil cause of action under § 9.73.060, meaning the person whose private communication was recorded without consent can sue for damages. So while Washington's criminal classification is less severe than some all-party states, the combination of a criminal charge and civil liability still makes an unannounced recording a real risk, not a technicality.
Exceptions and nuances
The statute's core mechanism — obtaining consent from all participants — is satisfied by a clear announcement at the start of the call. Washington law does not require a signed release or a separate written form; it requires that consent actually be obtained, and an announcement that the other party hears and continues the call after is the standard way parents and businesses alike establish that. Washington's Privacy Act also contains other specific statutory exceptions (for example, certain emergency and law-enforcement recording situations), but for a parent recording calls with a co-parent, the announcement-based consent is the relevant and reliable path.
Using it in a Washington custody or co-parenting case
Washington family courts, like most, are unreceptive to secretly recorded conversations — a recording made without consent violates the Privacy Act and risks exclusion from evidence, along with undermining the credibility of the parent who made it. The straightforward, compliant approach is to make the recording announced: say clearly, at the start of the call, that it is being recorded, and let the other parent's continued participation stand as their consent. That approach is fully satisfied by RCW 9.73.030, and it produces exactly the kind of clean, lawful, dated record that a judge weighing a parenting-plan or custody dispute wants to see — not a recording whose legality can be challenged before anyone even gets to what was actually said.
How Copareo handles this in Washington
Copareo Secure Line treats Washington as one of its all-party states (alongside California, Connecticut, Florida, Illinois, Massachusetts, Maryland, Michigan, Montana, New Hampshire, Nevada, and Pennsylvania). When a parent's profile is set to Washington, the product automatically plays a clear, spoken announcement at the very start of every call it records — before any content is captured — and this cannot be disabled by the user. It is a deliberate product guardrail built to satisfy RCW 9.73.030's consent requirement on every single call, so a Washington parent using Copareo is never exposed to the risk of an unannounced recording. Every call is then transcribed and organized into a dated, exportable archive designed for an attorney or a family court filing.
A note on slug and scope
This guide covers Washington State, governed by RCW 9.73.030. It should not be confused with the District of Columbia (Washington, D.C.), which has its own, separate and different recording law. If you are looking for the District of Columbia's rule, that is a distinct jurisdiction with its own statute.
Recording across state lines
If you are in Washington and the co-parent you are calling lives in a one-party consent state, do not assume the more permissive rule applies to the whole call. The safer and generally accepted practice is to apply the stricter of the two states' rules to the entire conversation — here, that means Washington's all-party consent requirement governs regardless of where the other parent is located. Announce the recording every time, no matter where the co-parent lives.
Frequently asked questions
Do I need written consent to record a call in Washington?
No. A clear, spoken announcement at the start of the call that the other party hears and continues the conversation after is generally sufficient to establish consent under RCW 9.73.030.
Is a violation a felony in Washington?
No, it is generally charged as a gross misdemeanor under the Privacy Act's penalty provisions (RCW 9.73.080), though civil liability under § 9.73.060 also applies.
What if the other parent hangs up after I announce the recording?
Then you do not have their consent, and continuing to record without it would violate the statute. Consent has to actually be obtained, not just offered.
Is “Washington” here the state or Washington, D.C.?
This guide covers Washington State (RCW 9.73.030). The District of Columbia is a separate jurisdiction with its own, different recording law.
Bottom line
Washington requires the consent of every participant before a call is recorded, and a clear announcement at the start of the call is the standard, reliable way to obtain it. Announce it, keep the archive dated and complete, and you are on solid legal ground — and in a stronger position in front of a Washington family court judge than a parent relying on a secret recording.
