title_body: Is owning, but not flying, a drone in Germany illegal? I live in Germany but I travel a lot around the world; my new hobby is aerial photography, for this I am considering buying a drone.
  
  Since Germany has some rules about drones, can I have a drone in Germany without a &quot;mandatory label marking,&quot; &quot;without insurance,&quot; etc?
  I mean, the rules are clear to me IF AND ONLY IF I am flying the drone in Germany, but what if I use it only when on vacation in other countries? Am I breaking any rules?
upvoted_answer: According to the rules you linked to, the only thing you are required to do is stick a label on your drone with your contact details, so stick a label on!
  All the remaining rules relate to when, where and how you fly, and what certificates you might need to do so. Since you won't be flying, none of these apply.
  Nowhere is there any prohibition on simply owning a drone.
  However, since this is your new hobby I find it unlikely that you won't want to fly in your home country. You'd need a 'certificate of knowledge' which doesn't seem to be too hard to get, and permission if your drone is over 5kg. Why not just get what you need and fly in Germany?
  Note that flying drones in other countries may have rules that are much more stringent than Germany. Don't expect to just rock up on some foreign beach and fly.
