Hello! Recently, I began publishing fiction stories in different magazines, using a nick name (pen-name). In the future there's going to be a novel too. I wanted to check if there's some legal actions I need to do regarding the pen-name. Should I register it somewhere? Can someone steal it (publish under the same name)? Can someone claim they used it before and I stole it? (I found no writers with such name, but saw that a couple of people used it as a nickname in different social networks/forums).I'll be thankful for any advice on the matter!
I live in Israel but publish in USA/British magazines.
