I wanted to make a post about the last names since I just went through this and wanted to share my experience. I haven't posted on this board much lately but I feel this is really important.
My ex and I broke up when I was pregnant and I told him that since we weren't together and we weren't picturing a future at the moment that I was give our son my last name. Of course this promoted huge arguments, and him threatening that he wouldn't sign the birth certificate, wouldn't come to the hospital ect. I kept to my guns and when Wyatt was born I not only had my Mom in the delivery room (I had to have a c-section), when it came time to fill out paperwork I gave Wyatt my last name. My attorney advised me to have Josh sign the birth certificate because if not, it would only add to more court paperwork and more money. In Georgia we also sign a "paternity affidavit" and legitimization (since we weren't married )which stated that we were both agreeing to the last name. Legitimizing Wyatt means that Wyatt is his son and he is entitled to all inheritance in case something happens (401k, life insurance ect).
Now years later (my son is 3.5), my ex filed for a name change which ended in a very long court battle. Now because he signed the birth certificate and legitimization at the hospital the judge felt like that was enough for the name to be the same. Because he signed the paperwork GA law states that in order for Wy to have his name changed BOTH parties have to agree.
I just wanted to share this information for anyone going through this right now

So if you're battling with this I hope this helps.
