UK, Ireland / Question about marrying abroad? I'm from UK, my fiance from Poland. [5]

Helloooo

I am from the UK, my fiance from Poland. We are planning to get married in Cyprus and have run into confusion regarding legal documents.

I understand as a UK national I would require a Certificate of No Impediment within 3 months of date of marriage to legally confirm there are no objections to our proposed marriage.

Does anyone know of the equivalent document for my fiance? She lives with me in the UK, is it possible to obtain a Certificate of No Impediment via a Polish embassy, by post or via the church?

Any help would be much appreciated as we are not sure what to do hehe

Thanks,

Jimmy
