Go to Philippine Embassy and they will give you the Complete List...if you can't, then here are some:

NOC from Company/Sponsor (both party) allowing you to get married
CENOMAR (Certificate of No Marriage) from NSO, attested by DFA, for both
Birth Certificate from NSO, attested by DFA, for Both
Parental Consent (those 25 yrs and below)
Pictures

Those were the requirements i submitted 3 yrs ago...i don't know if some things have been changed...the best is, proceed to embassy and they have a complete checklist.
