супругу киприота не требуется разрешение на покупку недвижимости?

Так ведь должно быть без разницы. Но в данном случае - супруге киприота.

Разве в законах прописано отдельно для супруга и супруги?

А во многих местах пишут, что не нужно: All nationals of non-EU member states/foreigners (foreigner under Cyprus Law is any person who is not a citizen of the Republic and includes a foreign controlled company – not including non-Cypriot spouses of the citizens of the Republic) can only acquire immovable property after obtaining the approval of the Council of Ministers. These powers have been recently assigned to the pertinent authorities of every district in order for the procedure to become speedier.
