legal and industy obligations

When it comes publishing an important part is the contract otherwise if wanted to take it to the court for any reason the contract could always come in handy.

Another is copyrighted when it's your own story you take all rights to that story so if someone else writes a story similar to what you've written you can take them to court because you've got all rights to that story. Also if you the author wants to create the cover you also gave rights to the graphics and images but this is only if you took the picture or design it.

Brands are something very important. When writing a book it's best not to use any brand names because if you use it in a bad way in the book you could get sued so always best just to make a brand up of just don't say a brand full stop.
