In 2-party consent states, do you need permission to record a conversation if the other party already has yours?
<p>If one of the two parties to a conversation in a 2-party consent state has the permission of the other to record the conversation, does the other party need to obtain permission to do the same as well?<br>
Or is everyone allowed to record without permission once a single party has permission to do so?</p>

<p>Technically the states that aren't 1 party consent are all-party consent. See Washington's <a href="http://app.leg.wa.gov/rcw/default.aspx?cite=9.73.030" rel="nofollow">RCW 9.73.030</a> for an example. </p>

<blockquote>
  <p>(1)...it shall be unlawful ...to intercept, or record ... without
  first obtaining the consent of all the participants in the
  communication</p>
  
  <p>(3)...consent shall be considered obtained whenever one party has
  announced to all other parties engaged in the communication or
  conversation, in any reasonably effective manner, that such
  communication or conversation is about to be recorded or transmitted:
  PROVIDED, That if the conversation is to be recorded that said
  announcement shall also be recorded.</p>
</blockquote>

<p>When I announce that I am going to record, then by continuing to talk the other parties are deemed to have consented to <em>me</em> recording (because I am a very trustworthy guy). That does not mean that anybody else can record without likewise announcing that they are going to record, whereby they can consent to this other less-trustworthy guy also recording them.</p>
