i agree with Iain as i intend to get married in the philippines at some time as well as here i have read the threads and there is no mention of divorce registration required in the philippines and this from guys who have been through the process would suggest you ask him for the law or where this is stated and tell him you know of friends who have married with out this and all you require is the CNI try to do this privatly so he doesnt loss face and offer to take him to lunch !!and smile ... i had a big disagreement with PAL flyng from manila to dumaguete at check in i just smiled a lot spoke quietly was very polite (yes mam however....) asked to speak to supervisor and stuck to my guns ended up with smiles allround photographs and no loss of face...a smile goes a long we and sense of hummour...
it will be ok


good luck regards
