'am not a Lawyer, napadaan lang.

Nais ko lamang itanong kung bakit binabawi mo ang iyong apelyido?

May nadiskubre ka ba na puwedeng maging dahilan ng pagbawi mo nito? Napatunayan mo ba na hindi mo siya anak sa paraang kinikilala ng batas, say DNA testing?

Kung hindi naman, at siya talaga ay dugo't laman mo, naniniwala ako na hindi mo mapi-prevent and continued use of your surname. Remember, nasa Birth Certificate and pirma mo acknowledging na siya ay anak mo.

Sa kabuuan, maliban na lang kung may meritorious reason/s that you may be allowed pero kung kapritso, something like that tingin ko you cannot.

well thanks sa pagreply.

the reason ng pagbawi ko sa surname nia is this,kmi ng nanay nia ay matagal ng hiwalay almost 8 years na mahigit. since then minsan ok paguusap naming about sa bata then minsa hindi so medyo magulo.

sinasabi nia minsan na isoli ko na lang surname ng bata dahil kaya naman nia itong buhayin
hanggang kinasal na ako at ngayon nagiging issue ang lahat at nagugulo nia ang relasyon naming magasawa.

para sa ikatatahimik ng lahat ibabalik ko na sakanya dahil yan naman ang gusto niang mangyari
