I did see that other thread. I defer to others eg
@Kaibigan - but it's possible still that a lawyer could help.
Crux of the question, and answer to which I do not know - since
@Kaibigan used the term - is whether the marriage is 'perfected' (still valid etc) if missing whatever doc you didn't get.
I believe you COULD argue that for all relevant purposes in Canada, the PH marriage certificate is valid (facially at least) unless some fundamental principle of marriage recognition under Canadian law - eg bigamy - was violated.
But if eg some additional step or affirmation ('perfection' as I understand the term) required to confirm that validity is needed , then my point may be ... well, wrong.
There is a question of PH law at hand here (eg whether the PH marriage would be considered valid or invalid in PH, and whether in fact invalidity is something that would require additional steps (someone to challenge it), and/or whether Canada should/would simply recognize a marriage certificate that appears valid. So it's both a PH and Canadian law question, I think.
