Good Noon, I have a daughter who is now 16 years old, my late husband is not the real father of her, this is the story: After 3 years of my marriage my late husband and I got separated for some reasons, after a year of separation, I met another guy and I had an affair with him and I got pregnant by him, but before the birth of my daughter my late husband came back and helped me with all the documents including birth certificate of my daughter and because we are married the surname of my late husband automatically attached to my daughter's birth certificate as well as his name as the father. After 5 months I delivered my daughter, my late husband started to act differently, I could tell my baby were not safe to my late husband's care, he do some weird actions whenever he was with my baby, there were times he let my baby cry and cry and not giving her any bottle of milk so I decided to just get off with him. I got my baby and we started living alone. After how many months of getting off from my late husband, I talked with the real father or the biological father of my daughter, I asked what was his plan about me and our daughter. I love my daughter very much and I would do everything to let her live and gives her a better life. After how many months, me, the biological father and our daughter started to live in one house as live-in partner, we cannot marry because I was once married. When my daughter started her schooling we let her use her biological father's surname at school, though her original birth certificate is on my late husband's surname. My daughter is now 16 years old and ready to go into her college school, she is a very bright student and excels in academics and non-academics, she even passed the entrance exam in one of the prestigious university here in the Philippines, the big problem is, her birth certificate, while she is still using her biological father's surname, her original birth certificate still on my late husband's surname and I want this to be fixed. Please let me know what option I could do for this to fix. I want the surname of my daughter be replaced to the surname of her biological father on her birth certificate. Thank you in advance for your help. God Bless and More Power. Evelyn
