Just a couple of thoughts on this:

1 If a couple get an annulment, then it would appear that as the parents were never married (that is what an annulment is, as opposed to a divorce) then the children must be illegitimate,

2 If a non-Filipino partner gets divorce (in another country) but his wife is not recognised as being divorced in Philippines, and the former non-Filipino partner gets married, maybe even in The Philippines, then the Filipina who is ‘not divorced’ is still married to a person is married to someone else !

Is it not well over due that Divorce is introduced in Philippines, if only to avoid the Philippines judicial system looking foolish.
