Please, do NOT hire a lawyer to copyright something.

You can do it yourself REALLY easily.

1. Go to www.copyright.gov and browse around and learn all you can.

2. Go to the online registration portal: https://eco.copyright.gov/eService_enu/start.swe?SWECmd=Start&SWEHo=eco.copyright.gov

3. Follow the simple steps, and pay the low fee.  

4. You're done.  

Sure, if you really have difficulty on the site or just want the peace of mind of having a lawyer do it for you, that's fine.  But please, try to do it yourself first.  You'll be surprised with how easy it is.

NOTE: If you're also a screenwriter or teleplay writer, register your screenplay with the Writer's Guild too: https://www.wgaeast.org/script_registration
