Permit rules for foreign buyers, Polish wills and zachowek, and the EU succession regulation.
Houses and land vs apartments: when foreigners need a permitNon-EU citizens generally need an MSWiA permit to buy a house with land or a plot, while a standalone apartment (lokal mieszkalny) is usually permit-free.
Wills in Poland and the zachowek reserved shareYou can write a Polish will by hand or before a notariusz, but close family you disinherit can still claim zachowek — a statutory share of the estate's value.
Cross-border estates: the EU succession regulationIf you live in Poland permanently, EU Regulation 650/2012 makes Polish law govern your whole estate by default — unless your will chooses the law of your citizenship.
