We married in Dalaguete Church in Cebu, and had to jump through quite a few hoops. Obtaining a letter from the Catholic Church Parish Priest in the UK was quite a difficult one (especially since i'm Church of England), and required attendance at his mass and a few meetings with him, and he really didn't know what he was supposed to be giving and referred it to up the chain of command.

We ended up having an interview with priest at the chancery, then at Dalaguete church and also attending the Pre-Cana Seminar. The whole process took weeks.

The Pre-Cana Seminar costs 700 peso, and is held on Mondays, Wednesdays and Fridays in the Cardinals Palace, running from 08:30 to 12:00 (ours took a lot longer). You need an appointment for this and sometimes its book up for weeks in advance.
