I am married to a dutch national and have a permanent dutch residence permit. I am planning to move to Germany with my wife where we both will work and i will enroll in a university for my masters. Can anyone tell me after moving there what legal requirement we need to do. Do i a non eu spouse having a dutch residence permit need to apply for German residence permit ? or any other legal requirement we need to do
You are covered by the freedom of movement EU law.
The ministery of the interior says you basically only have to register your new residence (as every German would have to do, too, when they move inside Germany) with your local "Meldebehörden" in the city you move to. That would be the "Ordnungs-Amt", the civil administration office. They will make sure the foreigners office gets all the documents they need.
You may need to provide proof of what you claim (that would mean your passports, a marriage certificate at least one work contract and/or sufficient funds) but that's just a formality. There is no proceedings or checks, you already have the permission by virtue of your wife's nationality, all you need to do is fill the paperwork.
