Rules
The rules of entry and return to the Czech Republic for citizens and residents of the Czech Republic also apply to family members (spouses, registered partners, spouse) of Czech and EU+ citizens who are holders of a temporary residence permit in the EU+ (need to provide proof of family relationship, e.g. marriage certificate, proof of registered partnership). You can find them clearly in the scheme (only in Czech) of the Ministry of the Interior. For a more detailed explanation of the conditions, see the Ministry of the Interior's chart (only in Czech).
Anyone who crosses the border to/from a neighbouring country at least once a week to visit his/her spouse, registered partner who works or studies there does not have to comply with the rules for entering the Czech Republic.
The restriction on entry into the Czech Republic of citizens of third countries that are not on the list of countries with a low risk of infection does not apply to foreigners who are family members (spouses, registered partners, partners) of Czech citizens or EU citizens residing in the Czech Republic. The ban also does not apply to foreigners who are in a partnership with a Czech citizen or an EU citizen with a temporary residence in the Czech Republic (they must have a permanent partnership relationship based primarily on cohabitation). These foreigners may enter the Czech Republic on the basis of a certificate issued by the Ministry of Foreign Affairs.At the same time, they must undergo an appropriate test before travelling to the Czech Republic. You can find out what kind of test it is in the Possibilities and Obligations of Foreigners Entering the Czech Republic (the test certificate can be in paper or electronic form and you can use this PCR test confirmation form or antigen test confirmation form).
The ban on entry of citizens of countries with an extreme risk of covid-19 and foreigners who have stayed in these countries for more than 12 hours in the last 14 days does not apply to foreigners who are family members of a Czech citizen and hold a temporary residence permit in the Czech Republic (this do not apply for a spouse).
