In fact when I got married June 2014 I didn't need to go the registry office as it had just the previous month changed. But as it is with these sort of things, nobody knew. Even the lady in the registry office told me, off course they arenot going to do away with you needing to come here, nice little income for us.
So I went anyway and did what I had to. Good job I did, because although they were aware in some places of the change in Philippines, the middle of nowhere my wife comes from didnt know.
Off course they all know now.
All I advise is you check everything you get told, either by asking here. Or researching on the internet. As things change all the time.
It can be a big headache all the paperwork... But unless you want to throw money away I wouldn't pay anyone to do the work for you.....
