SURNAME PROBLEM PLEASE HELP

Good Day, I'm Christian and I want to ask kung pano po yung gagawin ko? I'm 18 years old and gusto ko po sana papalitan yung last name ko, kasi po ang gamit kong last name ngayon ay sa stepdad ko, gusto ko po sanang gamitin yung sa biological dad ko which is nasa japan po and yes po, japanese po sya. before po yung gamit kong last name is yung sa mother ko pero namatay na po sya pero before nag pakasal si mother ko sa stepdad ko and nilakad nila yung nso ko and ang nagamet ko na po is yung stepdad ko, sana po matulungan nyo ako since matanda na po si biological father ko po, need ko na po maayos to para makapag japan na din po ako at makasama ko si daddy

What is in your birth certificate?

GRAFIL po, gamit ko po yung sa step dad ko po

So your mother basically simulated your birth certificate, and placed therein the name of a person who is not your father.

You will have to go to court to get this corrected. But as to the use of your father's surname, you have to prove that you are actually related to him, and that he is allowing you to use his surname.

anong documents/proof need ko po para patunayan na biological father ko po sya? nasa japan po sya eh

before po ang gamit kong last name is yung sa mother ko, then nag pakasal po sya sa step dad ko po ngayon ang ang ginagamet ko na pong last name is yung sa step dad ko which is GRAFIL, inayos po nila NSO ko

hindi po nagpakasal yung biological father ko and yung mother ko, nag live in lang sila then nabuo po ako

A DNA test will clear this up.

dna test po? tapos po after nun ano pa po?

kelangan pa po ba nya umatend sa korte po? ganunpo kaya katagal yon and regarding po sa mga fees? mga magkano po kaya aabutin?

Hire a lawyer where you are. They will know what to do. You cannot correct an entry just by the simple expediency of changing the biological father's name administratively. You will have to go to court. Your petition might even have to be published. Legal fees depend on the standard where you are, the publication costs, and the court costs.

okay po, thank you very much po sa informations
