Nobody brings up the split sheet because they don’t want to be the one who made it weird. You’ve just spent three hours building something together, the room is good, the song is good, and asking “so what do we each own?” feels like you’re putting a price on the trust. So most people don’t ask. They shake hands and leave.
And sometimes that’s fine. And sometimes, two years later, the song gets a sync placement and there’s no document in the world that says what either of you agreed to. I’ve watched that exact situation curdle a friendship more than once.
What a split sheet actually is
A split sheet is a one-page record of who owns what percentage of a song. Not a contract, not a negotiation. It’s the least lawyerly document in music. Its power comes entirely from when it gets signed: the same day as the session, while the memory is still fresh and the relationship is still intact.
What it records is the composition split: the ownership of the melody and lyrics. If the session also produced a master recording, you can note that separately, but composition is the core. When a publisher wants to license the song, when a music supervisor needs to understand what sync licensing requires, when a PRO pays out performance royalties, the split sheet is what tells them who to pay and in what proportion.
A split sheet signed on the day is a record. A split sheet signed three weeks later is a negotiation.
What goes in one
Six things. That’s all a split sheet needs to be useful:
Song title and the date it was written. Each writer’s full legal name. Each writer’s PRO (APRA, ASCAP, SESAC, BMI) and IPI/CAE number. Percentage splits for the composition, which need to total 100%. A note on master ownership if the session produced a recording. Signatures from everyone.
A Google Doc with those fields, signed by both writers on the day, is worth more than a formal template sitting unsigned in someone’s files. The document’s formality doesn’t matter. The signatures and the date do.
On splits: most sessions default to equal. 50/50 for two writers, regardless of who wrote which line. Equal defaults remove the need to measure contribution, which is the thing that corrodes co-writing relationships. Unequal splits make sense when someone brought a finished track or a defining riff, but that conversation should happen at the start of the session, not after. Understanding how your song earns performance royalties makes clear why getting the percentages right early matters: every split decision you defer is one you’ll eventually have to un-defer, usually under worse conditions.
How to bring it up without making it weird
The resistance isn’t really about distrust. It’s about framing. Raise a split sheet at the end of a session like you’re opening a negotiation and it feels like one. Raise it like you’re filling in a form and it feels like a form.
Three moves that work: First, mention it at the start. “I always fill in a split sheet at the end of sessions, just a habit.” Said once, early, it becomes routine rather than pointed. Second, default to equal and say so. “I’m happy to split this 50/50, does that feel right?” A question, not a demand. Third, have the template ready. Pulling up a blank document at the end signals you do this every time, not that you distrust this particular writer.
The same instinct that makes a co-writing session productive, treating the collaboration as a shared project rather than a negotiation, is exactly what a split sheet protects. It keeps the business end clean so the creative relationship doesn’t have to carry it.
The writers who skip the split sheet aren’t avoiding awkwardness. They’re just moving it downstream. And the ones releasing the song independently without one are the first to discover what “downstream” actually means.
If you’re heading into a session and want to think through how to structure it, whether that’s splits, process, or anything else, reach out directly. That’s the kind of conversation worth having before the session, not after.
No. A split sheet is a record, not a contract. A simple document with names, percentages, PRO numbers, and signatures from the same day as the session is legally sufficient, and practically more valuable than a formal template that never gets signed. For songs with significant commercial potential, an entertainment lawyer is worth involving at the publishing agreement stage, not the split sheet stage.
Most co-writing sessions default to equal, 50/50 for two writers or 33/33/34 for three, regardless of who wrote which line. Equal splits remove the need to measure contribution, which is what corrodes relationships. Unequal splits make sense when someone brought a finished track or a defining riff that shapes the whole song, but that conversation should happen before the session, not after.
The composition split covers the melody and lyrics, and this is what a split sheet typically records. The master is the specific recording of the song. If you co-write but record separately, the two splits can differ. If you produce the track together in the same session, it’s worth noting both on the same document.
You negotiate under pressure instead of agreeing in good faith. Memories diverge. The publisher, label, or supervisor trying to clear the track has no document to work from, which creates delays and sometimes kills the deal entirely. Most co-writers who’ve been through a disputed split once become the first to pull out a template at every subsequent session.
Both parties can agree to amend it, but the amendment needs to be documented and re-signed by everyone. If the song has already been registered with a PRO under the original split, that registration will also need to be updated. This is why getting it right at the session is worth the five minutes.
