Pineke ang pirma ko sa acknowledgement of paternity?

Yes but in this case sa korte na po yan. You need to have evidence to support aside from your allegation na forged and signature po ninyo. Like DNA result ng bata na hindi talaga ikaw ang ama bata. Wala talaga kayong relation ng mother or never kayong nagtalik. You need testimony of your witnesses. Another proof then pertaining sa forged signature if you see sa Certificate of Live Birth ng bata notarized po yan likod nito so you can search for the lawyer that notarized it. You ask for the copy of his notarial book sa sinabi po ninyong hindi po kayo ang pumirma sa acknowledgment part ng Certificate of Livebirth possible hindi karin pumirma sa notarial book ng notary public. That will support na forged lang ang signature po ninyo. If nasubmit na po ang notarnial book ng lawyer maari po kayong humingi ng certified true copy of his notarial book sa Notarial Division where the said notary public is registered. You need a lawyer to help establish your defense po.
