Civil Wedding

Hello everyone! My partner and I are both 23 years old, may anak na po kami and currently pregnant. And isa sa mga requirements for civil wedding is parental advice from both of our parents and kailangan ng personal appearance nila. Pano po pag di sila available for personal appearance pwede na po ba affidavit of parental advice/written letter yung ipasa namin na requirement? Thank you po sa makakasagot :) #pleasehelp #advicepls
