I would really appreciate some help to understand if me and my husband are eligible for double household in Germany.
Please bear with me while I unfold my love story
2016: Me and my then-boyfriend met in our country (non-EU) and after a while he started a job as an engineer in Munich.
We did back and forth for a year.
2017: After one year, I started a job as an engineer in Poland. He continued to work and live in Munich and traveled every weekend to Poland so we could meet (we have proof of that from the auto rental payments)
2018: I started a job in Baden Württemberg. He continued to keep his house in Munich, as his job is there, but was spending 3 days a week at my house - weekend +one day home office.
2019 - we got married. He is still living in Munich and I in Baden Württemberg, due to work. He continues to come in Baden 3-4 days per week.
My husband was always registered in Munich, and I was registered in Baden. He never registered in Baden. The whole time we have paid double for everything: rent (regular, unlimited rental contracts) additional expenses, travel etc.
First, I would like to know if we are eligible for double household (Doppelte Haushaltsführung) - if yes, does it count only after marriage or previous years count as well?
I understand this might be a complicated matter and should be addressed to a professional, but I would like to have an idea if this is possible at all.
Thank you for reading through to the end!
