If you are marrying in a non-English speaking country then these may all have to be translated by an official translator and stamped with an apostille.
Some countries also require these documents:
Certificate of No Impediment to Marriage (CNI)
This can be obtained from your local register office or your consulate/embassy in the country in which you are getting married.
Certificate of Single Status/Sworn Affidavit that you are free to marry
These are similar to a Certificate of No Impediment, but instead you have to swear you are single in front of a legal representative (solicitor/notary).
Apostille Stamp and translations
Some countries require foreign legal documents to be stamped with an apostille which then makes them legal documents in that country.
You may also have to have your documents translated officially and then stamped with an apostille – it really depends on the country in which you're getting married.
