When assessing eligibility for Polish citizenship by descent, it is necessary to analyse not only whether Polish citizenship was held by an ancestor, but also all facts and events from that ancestor\u2019s life that could have affected their citizenship status.<\/span>

<\/b><\/p>

According to the current regulations the only way to lose Polish citizenship is by official renunciation of Polish citizenship.<\/span>
<\/span>This means that today Polish citizenship cannot be lost automatically or unintentionally.<\/span><\/p>

In the past, due to changes in Polish citizenship law within years, it could be lost due to events that took place in your Polish ancestor\u2019s life by for instance service in a foreign army, marriage before 1951 in case of females etc.<\/span>
<\/span>These historical regulations are crucial when analysing citizenship by descent cases today.<\/span><\/p>

Below, you can find a list of the most common events and situations that could lead to loss of Polish citizenship by your Polish ancestor.<\/span>
<\/span>Each case is analysed individually, and legal interpretation as well as historical context may play a decisive role.<\/span>
<\/b> Please note that each case is assessed and analysed by our Polish citizenship expert on an individual basis and with individual approach and there is often room for interpretation and in some situations, exceptions may be applicable which will save your <\/span>Obywatelstwo polskie przez pochodzenie<\/span><\/a> sprawa.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If your male ancestor served in a foreign army before 19th of January 1951, he likely lost his Polish citizenship.<\/span>
<\/span>This resulted from provisions of Polish citizenship law in force at that time.<\/span><\/p>

There are exceptions in case of WWII period if served in the alliance forces during the war or in case of forced army draft.<\/span>
<\/span>Such exceptions must be supported with historical and legal evidence.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Holding public positions before 19th of January 1951 could lead to loss of Polish citizenship.<\/span>
<\/span> Public positions are considered teachers at public schools, politicians, doctors at public hospitals for example.<\/span><\/p>

Employment in the public sector of a foreign state was treated as an act affecting Polish citizenship.<\/span>
<\/b>But in case your ancestor was a teacher at a private school, this needs to be proved and supported with evidence of employment. A similar situation applies to doctors working in private hospitals or clinics.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If your mother, grandmother, great-grandmother (so female ancestor after whom you wish to claim your Polish citizenship) took foreign citizenship before 19th of January 1951, that could lead to a loss of Polish citizenship.<\/span>
<\/span>This was a result of discriminatory legal provisions that applied specifically to women at that time.<\/span><\/p>

What could protect her is if she was a minor child, when naturalization happened, and she became an adult after 19th of January 1951 and she was protected by her father\u2019s conscription age.<\/span>
<\/span>Such circumstances require careful legal assessment.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Official and legal renunciation before Polish Authorities e.g. Polish Consulate abroad.<\/span>
<\/span> In some cases, Poles that left Poland, due to communism period or other personal circumstances lodged official renunciation of Polish citizenship before the Polish Authorities.<\/span><\/p>

An official renunciation decision often affected minor children listed in the application or decision.<\/span>
<\/b>This also often impacted minor children in case they were listed on the decision.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Official application for permission to change citizenship.<\/span>
<\/span>In the past, such applications were required even though Polish law did not always mandate them.<\/span><\/p>

A similar situation to renunciation applied to those who officially applied to the Polish Consulate to change their citizenship, even though they did not have to do that, and while taking foreign citizenship, they could keep Polish citizenship.<\/span>
<\/span>If such an application to change citizenship was officially lodged and accepted, Polish citizenship was lost.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If your male ancestor after whom you wish to claim your Polish citizenship took foreign citizenship before 19th of January 1951 and was born before 1901, he lost his Polish citizenship due to conscription age not protecting his Polish citizenship.<\/span>
<\/span>The year of birth and conscription age played a key role in these cases.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If your ancestors stayed in the USSR territory after the war, even if they were Polish citizens, they lost their Polish citizenship by automatically obtaining citizenship of the USSR.<\/span>

Loss of Polish citizenship is often a controversial topic as in the past, people were not aware they were losing it.<\/span>
<\/span>Many individuals were unaware that specific actions had legal consequences for their citizenship status.<\/span><\/p>

Also, it is important to mention that even though Polish citizenship law was very discriminatory towards women before 1951 but it is still being taken under consideration while assessing and analysing Polish citizenship by descent application by the Polish Government.<\/span>
<\/span>Historical discrimination does not invalidate the application of the law in force at the time.<\/span><\/p>

This follows from the universal legal principle \u201ctempus regit actum\u201d \u2013 the effects of legal events are judged according to the laws in force at the time when the events occurred.<\/span>
<\/span>This principle is fundamental in Polish citizenship proceedings.<\/span><\/p>

Polish citizenship law along with its various acts may be complicated for those of you who are not familiar with the process.<\/span>
<\/span>Professional legal analysis is often necessary to correctly assess eligibility.<\/span><\/p>

Can Polish citizenship be lost automatically today?<\/b>
<\/b>No. Under current regulations, Polish citizenship can only be lost through an official and voluntary renunciation before Polish authorities.<\/span><\/p>

\u00a0<\/p>

Could my ancestors have lost Polish citizenship in the past without knowing it?<\/b>
<\/b> Yes. Before 19 January 1951, Polish citizenship could be lost due to events such as service in a foreign army, holding certain public positions, marriage or naturalization, often without full awareness of the consequences.<\/span><\/p>

\u00a0<\/p>

Does taking foreign citizenship always mean loss of Polish citizenship?<\/b>
<\/b>Not always. In older generations, especially before 1951, taking foreign citizenship could result in loss of Polish citizenship, depending on factors such as gender, year of birth, and conscription age.<\/span><\/p>

\u00a0<\/p>

Why are historical laws still important when assessing citizenship by descent?<\/b>
<\/b>Because Polish authorities apply the principle <\/span>tempus regit actum<\/span><\/i>, meaning citizenship status is evaluated based on the laws in force at the time the relevant events occurred.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
