What Is a Split Sheet and When Do You Need One Before You Release
A split sheet is a signed document that records what percentage of a song's composition each writer owns. It covers the underlying song only, not the recording. You need one the moment a co-writer, featured vocalist, or topliner adds anything, and you should sign it before the session ends.
What is a split sheet in music?
A split sheet is a written document that records the percentage of ownership each collaborator on a song holds. It becomes legally binding once everyone signs, and it stands as the agreed evidence of who owns what. It's also called a song split agreement or a split sheet agreement. Same thing.
What it governs is narrow and worth getting exactly right. A split sheet covers the composition: the melody, the lyrics, the musical structure. The underlying song. It does not automatically govern the master recording (the actual audio file you upload to your distributor), and it does not cover any label deal points. Those are separate agreements. Sources: Songtrust and Disc Makers.
So when you sign a split sheet, you're settling the publishing layer only. The recording side and any label split are documented somewhere else, on their own. People conflate the three constantly, and that confusion is where money goes missing.
A split sheet is a publishing document. It settles who wrote the song. It says nothing about who owns the recording or how a label deal divides the master.
What actually goes on a split sheet?
A split sheet needs enough detail that a PRO can register the work without guessing. Leave a field blank and registration stalls.

Here's the minimum required detail. The split sheet should carry the legal name of each contributor, their role (composer, lyricist, music and lyrics, or arrangement), their PRO or CMO affiliation (ASCAP, BMI, SESAC, and for Canadian writers, SOCAN), their IPI/CAE number (the unique ID your PRO assigns you), the publisher name and publisher IPI if you have one, the ownership percentage with all of them totalling 100%, plus the song title, date written, and signatures from everyone. Sources: ASCAP and Songtrust's split sheet download.
The percentages are the load-bearing part. If your numbers don't add up to 100%, or two people register conflicting shares, a PRO will hold the royalties until it's sorted out. That hold can run months. The split sheet is what stops it before it starts.
When do you need a split sheet before you release?
You need one the moment a second person contributes to the song. Not when a problem comes up. Not after release. The moment a co-writer, featured vocalist, or topliner adds melody or lyrics, you need it documented.
This is the part solo artists get wrong, so let me make it concrete with a constructed scenario. Say you're an indie-electronic producer. You write, produce, and mix everything yourself. On your own tracks, all three layers collapse into one person. You own 100% of the composition, 100% of the master, and you take 100% of streaming royalties minus your distributor's fee. No split sheet needed, because there's nothing to split. Source: Songtrust on producers and publishing.
Now you bring in a vocalist to topline a track. She writes a melody and the lyrics over your instrumental. The second she does that, the composition has two authors. That's the trigger. You need a split sheet, and the time to sign it is right then, while you both remember who did what and the song is fresh.
The reason to sign early isn't superstition. Music attorneys, publishers, and label staff all point to pre-release as the window that matters, because after release memories fade and leverage shifts. The person who feels they got shorted has every reason to renegotiate once a song starts earning, and you've lost the clean moment when everyone agreed. Source: ONErpm.
There's a default that kicks in if you skip it. In the US, under 17 U.S.C. 201(a), co-authors of a joint work each own an equal, undivided share of the whole, regardless of who did more. In Canada the Copyright Act doesn't set a default percentage at all, and legal commentators lean on general property law to presume equal shares, which leaves the position less certain than in the US. Canadian co-owners also generally can't license the joint work without every other co-owner agreeing, which makes the written agreement matter even more. The pillar covers that default in full, including how it plays out when money is already moving. Sources: Cornell LII and Lexology.
So we'll sort the splits later doesn't leave the splits undecided. The law decides them for you, evenly, whether that reflects reality or not. The cleanest version of this is to fill the split sheet out before anyone leaves the session.
Split sheet vs master agreement
A split sheet settles the song. A master agreement settles the recording. They're two different documents covering two different revenue streams, and one never substitutes for the other.
Here's why that distinction has teeth. When a track streams on Spotify or Apple Music, the payout splits into two streams. Roughly 80% flows to the master rights holder, and roughly 20% is publishing income, which then splits again between performance royalties (paid through PROs) and mechanical royalties (paid through agencies like The MLC in the US or CMRRA in Canada). Those ratios are industry conventions and vary by territory. Source: Sentric.
The split sheet only governs that 20% publishing slice. The 80% master side is governed by your master ownership agreement or producer deal.
| What it covers | What it pays out of | |
|---|---|---|
| Split sheet | The composition: melody, lyrics, structure | The ~20% publishing slice, via PROs and mechanical agencies |
| Master agreement | The recording: the audio file itself | The ~80% master slice, via your distributor |
| Artist-label deal | Your cut of master royalties after a label recoups | A percentage of the master slice |
This is exactly why a featured artist's name belongs in the master agreement, not the split sheet. A featured vocalist who performs on the recording but didn't write the underlying song has a claim to the master side. Putting them on the publishing split sheet because they sang on it is a common, expensive mistake. If your topliner wrote the melody and lyrics, that's a composition contribution and they belong on the split sheet. If they only performed someone else's words, that's a master-side conversation handled in a separate featured artist agreement.
The short version: ask whether the person changed the song or changed the recording. The song goes on the split sheet. The recording goes in the master agreement.
Frequently asked questions
Is a split sheet a legally binding contract?+
Yes, once everyone signs it. A split sheet is a written document that records each writer's ownership percentage in a song's composition, and it becomes legally binding upon signing. It then stands as the agreed evidence of who owns what if a question comes up later. It covers the composition only, so it isn't a substitute for a master ownership agreement or a label deal, which are separate documents.
Does a solo artist who writes and produces everything need a split sheet?+
Not for tracks they make entirely alone. If you write, produce, and mix the whole thing yourself, you own 100% of the composition and there's nothing to split. You need a split sheet the moment a co-writer, featured vocalist, or topliner contributes melody or lyrics. That's the trigger, and the time to sign is right then, before the session ends, not after release.
What fields does a split sheet have to include?+
Each contributor's legal name, their role (composer, lyricist, music and lyrics, or arrangement), their PRO or CMO affiliation, their IPI/CAE number, any publisher name and IPI, the ownership percentage, the song title, the date written, and signatures from everyone. The percentages have to total 100%. Leave a field blank and PRO registration stalls, so fill it out completely before anyone leaves the session.
When exactly should I sign a split sheet?+
At or right after the writing session, before the song is released. That's the window music attorneys and publishers point to, because everyone still remembers who did what and nobody's leverage has shifted. Once a song starts earning, a collaborator who feels shorted has every reason to renegotiate. A late split sheet is still worth having, but the easy version is the one signed in the room.
Should a featured vocalist go on the split sheet?+
Only if they wrote part of the song. A featured artist who performs but didn't write the melody or lyrics has a claim to the master side, not the publishing side, so they belong in a separate featured artist or master split agreement, not the split sheet. If your topliner actually wrote the melody and words, that's a composition contribution and they do belong on the split sheet.
