Dear @Ryou,
Welcome to the Wefugees Community and thank you for reaching out to us.
If you are married to a German citizen, your application for the residence permit according to section 28 of the German Residence Act is not dependend on your or your spouse's financial situation. Please see a list for the requirements here, for example.
However, the authorites may ask you to apply for the respective visa at the German embassy in your country of origin.
Am I right on this and do you like to add anything dear @mbeon-fardeen?
All the best,
Meike
