Welcome back to the Wefugees Community and thank you for reaching out to us again.
I am not sure if I understand your question correctly - you are asking if you can marry your partner who doesn't have a residence permit? In general, also Duldung holders can marry in Germany (please see also this thread: Can someone marry here in Germany with Duldung?). However, the registry office (Standesamt) will require many documents which people often struggle to provide.
Regarding a family reunification visa and a subsequent residence permit for the spouse of a recognized refugee:
Once you managed to get married and your partner applies for a residence permit according to section 30 of the German Residence Act, the immigration office will most probably ask your partner to apply for a specific family renunification visa at the German embassy in his/her country of origin. If this is not possible at all, I assume you will need a good lawyer supporting you to convince the immigration office to acccept your reasons/arguments. Another issue: Recognized refugees may have a privileged opportunity to apply for family reunification, if they manage to apply for the reunification within the first 3 months after the final BAMF/Court decision (Anerkennung). If they miss that deadline of 3 months, they will be asked (like every other foreigner) to be able to secure livelihood independently (from any social benefits) and to fulfill some other requirements (big enough flat etc.).
Am I right on this, dear @mbeon-fardeen and @mbeon-Rukundo and/or is there anything you may want to add?
I hope I was able to provide some useful information and please don't hesitate to get back to us in case I actually misunderstood your question or if you want to discuss further.
All the best,
