@J_Oz Same boat with you. Just my ACS docs for now.
I also just got married last June though I still have not yet requested for official NSO marriage cert. However we had the marriage certificate coming from Makati city hall just 1 month after the wedding day.
So you may use that, it has a stamp like CTC stamps ,that is from makati though not sure with other cities. And also Makati issues marriage cert in NSO like paper which was used for my wife's passport with updated last name (the CTC version is not acceptable to DFA). We got both after a month after wedding. So I guess if DFA accepts it, then maybe OZ will too.
So yun, just in case official NSO cert is too long for you and those other peepz here who just got married. π
