Are UK civil partnerships still &#39;monogamous&#39;?
<p>With civil partnerships soon opening to everyone in the UK, I have been unabe to find whether - like with marriage - you are limited to have one with only a single person?
Could some insight with sources be provided on this?</p>

<p>Yes.  Section 1 paragraph 1 of the Civil Partnership Act 2004 says:</p>
<blockquote>
<p>A civil partnership is a relationship between <strong>two</strong> people of the same sex</p>
</blockquote>
<p>[My emphasis]</p>
<p>To show that you can't form multiple civil partnerships, Section 3 says:</p>
<blockquote>
<p>Eligibility</p>
<p>(1)Two people are not eligible to register as civil partners of each other if—</p>
<p>(a)they are not of the same sex,</p>
<p><strong>(b)either of them is already a civil partner or lawfully married,</strong></p>
<p>(c)either of them is under 16, or</p>
<p>(d)they are within prohibited degrees of relationship.</p>
<p>(2)Part 1 of Schedule 1 contains provisions for determining when two people are within prohibited degrees of relationship.</p>
</blockquote>
<p>See: <a href="http://www.legislation.gov.uk/ukpga/2004/33/section/1" rel="nofollow noreferrer">http://www.legislation.gov.uk/ukpga/2004/33/section/1</a></p>
<p>The recently announced change to allow heterosexual couples to register a civil partnership will presumably just involve deleting &quot;of the same sex&quot; from 1.1 and deleting 3.1(a)</p>
<p>Formalizing polyamorous relationships is quite a way off I think (and will be quite a lot more complex).</p>
