Im 19 years old and I have a year old son. I was with this man for a year and a half and when we were together I had a baby which he knew wasnt his. When he and I started dating I was pregnant with another mans baby. The other man wasn't in my sons life or planning on it so the man I was dating signed the birth cert. and my son has his last name. Now me and this man are not together and he wants off the birth cert. and for me to change his last name. How do I go about doing so?
