Hi ,
as far as I remember.................i got my CNI here in the UK, went to British Embassy in Manila, this then qualifies you for the Phils version (which you need)...........you cannot get married without the Phils version..........if you have been married before and are divorced ( a Philippine citizen), you will have to produce the CENOMAR, which shows that you are NOT married at this present time to a third party.

Hope this is of some help......good luck
