Would there be a technicality on this?
Knowing both birth certificate and marriage certificate shows the parents name and mother's maiden name with Jr..
My friend's brother totally abandoned his wife and 2 children for many years and ran off with another woman in Singapore. He proudly said that after the annulment he won't have had to do with his children with her anymore. We advised our friend's sister-in-law to file RA9262. Her children still needs full maintenance/Support from their father (but due to a reason the new MEAN wife who is apparently married before the annulment has been granted) does not allow her husband to give any penny to his children. We all know this is another technicality because before the annulment was granted they are already married in Singapore which is not counted and is null and void.
