Thank you for sharing your situation with the Wefugee Community and sorry for the late reply!
I had a look at earlier questions on this platform and found this thread. I think you might find some relevant information here.
As far as I know, marrying in Germany (are you both in Germany?) does not require a residence permit. However, you will need to provide certain documents, as a valid passport, for example.
I hope this helps and all the best for you,
