If i dont put the fathers name on the birth certificate can i still get child support

You do not provide enough facts.The short answer is yes. However, it is likely that the father will want a paternity test to make sure the child is actually his child (I am assuming that the two of you were not married since you do not mention anything about that fact). Even if you go through DCSS, they will want to establish paternity. The information contained is general in nature, and may not apply to your particular factual or legal circumstances.

Yes, you can. You will have to open a Paternity case in Orange County, either through the District Attorney's office or through the family law courts, seeking to have him declared the father of your child. At this point, he has the right to request genetic testing to determine whether he is the father, and if he is, the court will order that he pay you child support.
