Co-writing is such a creative, fun, and often essential part of songwriting; we go into great depth on it in our Udemy course, The Art of Co-Writing and Collaboration.
One part of a great collaboration is an open and honest agreement on how to share the ownership of the song’s copyright (hint hint: split it evenly if the song was essentially written from the ground up together).
However you land on your splits, having a written document of your agreement is essential.
Here, we offer you a standard written split sheet that you can print and use in your co-writes. Make sure all co-writers sign the sheet, and retain a copy for their records.
Registering the copyright of a work is a different process, but this split sheet gives you a written record of your agreement that you can refer to when it comes time to formalising your splits when registering copyrights.
