Can confirm that there is no need to complete the family planning certificate if you are over the age of 24 in metro manila. Yes we did pay extra to not do it.
We did not go down this route but its even possible to get the marriage license without legal capacity depending who you know at the highest level. Luckily we have the legal capacity but for 25,000 pesos this could be waived and was even offered no 10 day waiting period. Yes a bribe can fix anything in Manila.
Actually my friend did not have legal capacity when he got married 8 years ago and he got the license without it.
But like I explained in an earlier post my fiance got my legal capacity in advance. The British embassy gave this to her knowing Im not there, so if this facility exists then obviously you can get the marriage license before your arrival.
