When is renunciation of citizenship effective from?
<p>Say a person is a dual UK/Australian citizen, and they decide to renounce their UK citizenship.  They submit the required paperwork to perform an effective renunciation.  </p>

<p>What date will their renunciation be effective from (i.e, what is the earliest date from which they are no longer considered a UK citizen under UK law)?  Is it:</p>

<ul>
<li>The date on which they sign their renunciation paperwork?</li>
<li>The date their paperwork is posted?</li>
<li>The date their paperwork is confirmed as being received?</li>
<li>The date on which their renunciation is formally confirmed?</li>
</ul>

<p>...or something else entirely?</p>

<p>According to <a href="https://www.gov.uk/renounce-british-nationality/after-youve-applied" rel="nofollow noreferrer">https://www.gov.uk/renounce-british-nationality/after-youve-applied</a>:</p>
<blockquote>
<ol start="3">
<li>After you've applied</li>
</ol>
<p>You’ll get a ‘declaration of renunciation’ if your application is successful. This will be your application form, officially signed and stamped.</p>
<p>The date your citizenship or status stops will be shown on the form.</p>
