found it for you
from Terpe:
As already mentioned the CNI is available from your local registry office. It takes 22 days from time of application. It's 21 days for the 'bans'.
For Philippines the CNI has only 3 months validity from date of issue, so don't get it too early.
I suggest you always check for the latest information for paperwork needed etc but in principle to apply for the Marriage License in the Philippines you should consider having the following:-
Your birth certificate
Your passport
Your C.N.I.
Your NSO CENOMAR (if needed, please check well beforehand)
Your Divorce decree asbsolute (if applicable)
Certificate of 'Pre-Marriage Seminar' (if needed, please check well beforehand)
Her N.S.O. birth certificate (This should be fresh from NSO on latest type of security paper. Check)
Her Passport (or other appropriate ID)
Her Barangay clearance (if needed, please check well beforehand)
Her community tax certificate (often called Cedula)
Her postal I.D. Address
Her CENOMAR
Her Parents signed advice form (for under 25 years)
Her Parents I.D.
Apply for the marriage license in your fiancée's home town (or locality of where marriage will take place)
You will most likely also be requested to attend that previously "Pre-Marriage Seminar" counselling sessions prior to being allowed to be married. Do check and ask when you apply for the marriage license
After you apply for the license there is a mandatory 10 day waiting period while the marriage banns are published
Hope this helps you
