This will be the first time that the grandmother and guardian of my nephew and niece will be requesting birth certificates onliine through https://psaserbilis.com.ph/Birth-Details. However, upon arriving at option "relationship to the owner of the document", there is no applicable option for a grandparent and/or guardian. For those with the same issue and have requested already successfully, can you give me any tips please. Their grandmother won't just choose any for the fear that it may constitute fraudulent data offense.
