Split Sheets: What They Are and Why Every Song Needs One

The short version

A split sheet is a simple document that records who wrote a song and what percentage each writer owns. That is all it is. If two or more people were in the room when a song came together, a split sheet is how you agree, in writing and while everyone still remembers, who gets what.

It is the single most important piece of paper in songwriting, and it is the one people skip most often.

Why it matters more than it sounds like it should

When a song makes money, whether from streaming, radio, sync placements, or sales, that money gets split among the songwriters according to their ownership percentages. If those percentages were never written down, you have a problem that gets worse with time:

• Memories fade. Six months after a session, two people can genuinely and honestly remember the split differently.
• Money changes the story. A song nobody argued about suddenly matters a lot when it lands a commercial.
• Registration requires numbers. When you register a song with a PRO (like ASCAP or BMI) or a distributor, you have to state the splits. Without an agreement, you are guessing, or fighting.

A split sheet solves all of this by capturing the agreement at the moment it is easiest to reach: right after you finish the song, when everyone is happy and nobody is counting money yet.

What goes on a split sheet

A good split sheet includes:

• The song title, and any alternate or working title
• The date it was written
• Every contributor's legal name and contact info
• What each person contributed (music, lyrics, topline, beat, and so on)
• Each person's ownership percentage, and these must add up to exactly 100%
• Each writer's PRO affiliation and IPI/CAE number (the ID your PRO uses to pay you)
• Publisher information, if anyone has a publisher
• Signatures from everyone

The percentages are the heart of it. How you divide them is up to the writers, and there is no legal formula. Some people split evenly regardless of who did what; others weight it by contribution. What matters is that everyone agrees and it is written down.

Songwriting versus the recording: a distinction that trips everyone up

This is the thing to understand: a split sheet covers the song (the composition, meaning the melody, chords, and lyrics), not the recording (the specific master you made in the studio). These are two separate things that make money separately and are owned separately.

• The composition is what a split sheet divides. If someone else covers your song, the composition earns.
• The master recording is a different asset, usually owned by whoever paid for or created the recording, and handled by different agreements like a producer agreement.

One song can have a split sheet for the writing and separate arrangements for the master. Do not assume a split sheet covers everything, because it only covers the songwriting.

When you need one

Every time more than one person contributes to writing a song. Co-writes, beats you wrote over, a friend who added the bridge: if they contributed creatively to the composition, they may have a claim, and a split sheet is how you make the ownership explicit. Even a quick session with a friend deserves one. Especially those, actually, because the informal ones are where disputes start.

What happens if you skip it

Legally, without an agreement, co-writers are often presumed to own equal shares regardless of who contributed what, which may not be what anyone intended. And practically, you get:

• Disputes when money finally arrives
• Songs you cannot register cleanly
• Placements you cannot clear because the ownership is unclear
• Relationships damaged over money that a five-minute document would have prevented

How keysig helps

keysig's split sheet flow walks you through it: add each contributor, set the percentages with a live check that they total 100%, capture PRO and IPI info, and everyone signs electronically. It takes a few minutes and it is done properly, with legal names, contact info, and the works, so the song is clean from day one.
