What major rights and obligations will UK citizens, residents, and corporations forego in Day 1 of a Hard Brexit?
<p>Disregarding for a moment the political and economical repercussions of a Hard Brexit...</p>

<p>What are the immediate legal repercussions of a Hard Brexit, from a stand-point of rights and obligations of legal entities (individuals or otherwise), prior to further modifications of the laws?</p>

<p>My very basic understanding based on 3 years of hearing about it are:</p>

<ol>
<li><p>UK laws derived from EU law continue to prevail until modified</p></li>
<li><p>Other country's local EU-derived laws will likewise prevail until modified, however, as currently written, those laws will
immediately cease to recognize the UK as an EU member</p></li>
<li><p>Because of #1 and #2, there are some asymmetries in outcome. For example: Tariffs on imported (EU to UK) goods stay the same, because
the local tariffs prevail until modified by new laws (#1); Tariffs
on exported (UK to EU) goods immediately increase, because EU
countries' local laws immediately recognize the UK as a non-member
state (#2).</p></li>
<li><p>UK citizens abroad in an EU country may lose the right to be there, and essentially become instant illegal aliens (using a U.S.
term), because of #2, unless they obtain a visa like any other non-member citizen</p></li>
<li><p>UK non-citizen residents who are EU citizens may continue to reside legally in the UK, because local UK laws derived from EU law continue to
prevail until modified (as per #1).</p></li>
<li><p>Likewise for corporations ability to do business; in parallel with #4 and #5: Non-UK corporations doing business in the UK will be able to continue to do so, while UK corporations doing business in EU countries would now need comply with "non-member rules," similar to American or Japanese companies. But what specific rights to UK companies enjoy today relative to their American or Japanese competitors when operating in the EU?</p></li>
<li><p>The legal status of the Irish border will be what was negotiated in the 1997 Good Friday agreement, which is of an open border, even as individuals become liable for visas and tariffs when crossing (which no one will enforce, but still legally required).</p></li>
</ol>

<p>Is this analysis correct, as it relates to the asymmetry of legal outcomes?</p>

<p>What other rights and obligations are directly impactful to any legal entities?</p>

<p>An attempted summary based on the given points:</p>

<ul>
<li>1)  and 2)  are correct

<ul>
<li>some of the EU specific laws have also been transferred into UK law, which can be changed at any time after Brexit</li>
</ul></li>
<li>3)  is not correct since no tarifs existed beween the UK and other EU countries (Common Market / Customs Area) 

<ul>
<li>EU trade selectors will apply to the UK as a third country</li>
<li>UK will/have create trade selectors that will apply for goods from <strong>all countries</strong> to the UK</li>
</ul></li>
<li>4)  will apply to <strong>new</strong> residence permit applications of UK citizens

<ul>
<li>existing UK residents will, in most cases, received a residence permit based on their previous time of residence

<ul>
<li>will vary from country to country (I haven't seen a summery of the differences) </li>
</ul></li>
</ul></li>
<li>5)  I believe is not quite correct, since UK laws have been passed to 'transfer' residence and working rights into 3rd country residents rights</li>
<li>6)  For UK companies, inside and outside the EU, including their employees they will be treated as 3rd countries as stated

<ul>
<li>a few exceptions exist for the next 6 months</li>
<li>For EU companies in UK: no idea</li>
</ul></li>
<li>7)  is not correct for individuals

<ul>
<li>the regulations of the <a href="https://en.m.wikipedia.org/wiki/Common_Travel_Area" rel="nofollow noreferrer">Common Travel Area</a> will remain in effect, so there will be no changes for British and Irish citizens </li>
<li>both sides, to be WTO and GATT complient, should inforce custom tarifs

<ul>
<li>certain exceptions, for which the N. Irland situation is believed to be eligible, are possible 

<ul>
<li>but this aspect has been ignored upto now</li>
</ul></li>
</ul></li>
</ul></li>
</ul>

<hr>

<h3>Obligations:</h3>

<p>When the UK leaves the <strong>Common Market</strong>, i. e. Single Custom Area</p>

<ul>
<li>both will be obliged to <strong>refund</strong> collected VAT when goods are <strong>exported</strong> outside their Customs Area</li>
<li>both will <strong>collect</strong> the VAT when goods are <strong>imported</strong></li>
<li>both must supply the infrastructure to make this possible 

<ul>
<li>this will remain so independent of any WTO or Free Trade Deal constilation </li>
</ul></li>
<li>both must treat each other in the same way as any other 3rd country as long as trade is based on WTO rules (inforcement of tarifs) </li>
</ul>
