Dear @Chubby,
Welcome back to the Wefugees community and thank you for reaching out to us again.
The fact that you will be the father of a German child will not affect your chances in the asylum procedure and your appeal. However, you might be entitled to receive a residence permit according to section 28 of the German Residence Act. You did good already taking care of the paternity acknowledgment and the shared custody. This is important as it will be the actual support and care for your child. It’s possible that the immigration office will ask you to do the respective visa process as well though. We discussed this topic i.e. here before.
I hope this helps and please don’t hesitate to get back to us with any further questions.
All the best,
Meike
