OK so I had a baby girl on the 4 of November.. there is no fathers name on the birth certificate, only because I don't know who her father is.. my fiancé who is in iraq at this moment wants to adopt her when he gets back and after we get married. What do I do about this and how can I go about it?

You need to figure out who the father is.

Make a list of the possible men, and have DNA testing done.

Then have him sign over his parental rights, so that your husband can adopt.
