Split sheets and publishing splits, explained
How to write down who wrote what, before money and memory disagree.
Splits are simple while everyone is in the room and impossible once they are not.
What a split sheet is
A split sheet is a short document recording, for one musical work, who the writers are and what percentage each holds. It usually includes each writer's legal name, PRO affiliation, IPI number, publisher if any, and the agreed share. Everyone signs. It takes ten minutes.
That document is what your PRO registration, your library's metadata and any future publishing deal are all built on.
Writer share versus master ownership
Two different things, often confused.
- The composition is the song: melody, harmony, structure, lyrics. Writers own it.
- The master is the specific recording. Whoever paid for or made the recording owns it, unless agreed otherwise.
A sync licence needs both cleared. If you wrote and recorded the track yourself, you hold both — but say so explicitly rather than assuming.
How to decide the split
There is no legal formula. There are workable conventions:
- Equal splits between everyone who contributed original musical material. Clean, fast, and rarely regretted.
- Contribution-weighted splits when one person clearly wrote the core and others added parts.
A performer who played exactly what they were told to play is usually not a writer. A performer who invented the riff usually is. If it is genuinely unclear, err toward including them — a small share costs less than a stalled clearance later.
Common mistakes
- Agreeing verbally and never writing it down
- Forgetting the producer who reshaped the arrangement
- Registering different percentages with your PRO than the ones on the split sheet
- Splits that do not add up to exactly 100%
Keeping it consistent
Whatever you agree must match in three places: the split sheet, your PRO registration, and the metadata you deliver to a library. When those three disagree, income is held or misrouted, and the person chasing it is you.
