I believe, Terpe, a copy of the marriage cert and report of marriage that has been submitted to Philippine Embassy in London will be sent to NSO in the Philippines so that they will have a copy (that's why they are requesting 4 copies of everything during the process). So if a marriage cert is requested from NSO, they will just print that in NSO paper (I'm just not sure if it's just the Report of Marriage or the actual marriage cert coz I haven't requested any yet from NSO).
