I am German (born in Berlin 🙂 and did some searches in German with no result at all.
As Joanne mentioned, make sure you know all the rules for employment when in Germany. Since your husband is the one employed, his company may help you identify what you are or are not allowed to do. German laws are known for some rigidity.
R.I.P.P.E.D or not: I hope you will enjoy your stay in Germany. Viel Vergn├╝gen!
