7 Split Sheet Mistakes Costing You Thousands
Contents
Songwriter royalty collections hit a record €12.59 billion in 2024. More money is flowing to songwriters and producers than at any point in history.
And yet, hundreds of millions in royalties sit unclaimed in what the industry calls the "black box" — money that was generated but can't be matched to the right people. The MLC alone still reports roughly $397 million in adjusted historical unmatched royalties.
Where does it go wrong? Mostly at the source: missing split sheets, incorrect metadata, and preventable documentation errors. When Notes.fm ran a year-long beta in 2025, they identified over $10 million in missing royalties across their users. The average artist was owed $15,500.
These aren't edge cases. They're the result of common, fixable mistakes that start with the split sheet.
Mistake #1: No Split Sheet at All
Under US copyright law (17 USC Section 201), a song created by two or more people is automatically a "joint work." Without a written agreement, all co-authors own equal shares regardless of actual contribution. Two writers means 50/50. Three means 33/33/33. It doesn't matter if one person wrote the entire chorus and another added a single ad-lib.
Worse, each co-owner can independently license the song non-exclusively without the other co-owners' permission. Your co-writer can license your song to a brand you'd never work with, and you can't stop them.
Verbal agreements are technically enforceable, but nearly impossible to prove when it matters. PROs can't verify a conversation. Distributors can't process a handshake.
A split sheet takes ten minutes. A dispute takes months and thousands of dollars.
Mistake #2: Waiting Until the Song Takes Off
The person who was fine with 20% during a casual session might feel very differently once a song has 500,000 streams and a playlist placement. What was a friendly collaboration becomes a negotiation — or worse, a standoff.
And it's not just about percentages. Without a split sheet, sync placements fall apart. To clear a co-written song, every co-writer must approve the license. As Bay Eight Recording Studios notes: "The last thing you want is to get offered a $100,000 sync placement only to lose it because you can't get ahold of the drummer you cut into publishing a decade ago."
Sync supervisors don't wait. If your song can't be cleared quickly, they move on.
Mistake #3: Confusing Publishing Splits and Master Points
Every commercially released song has two separate copyrights:
- The composition (publishing) — lyrics, melody, musical structure
- The sound recording (master) — the specific recorded performance
Publishing splits determine who owns the composition and receives songwriter royalties. Only people who contributed to the songwriting belong here. Master points are a percentage of the sound recording's revenue, typically 2-5 points in a separate producer agreement.
The mistake: a producer who should receive master points gets put on the publishing split sheet instead. Everyone listed on the split sheet must approve sync licenses. Put your mix engineer on the split sheet as a courtesy, and you've given them veto power over every sync deal for that song.
| Role | On the split sheet? | Compensation |
|---|---|---|
| Producer who wrote the beat/melody | Yes (as Composer) | Publishing royalties based on split percentage |
| Producer who mixed/engineered only | No | Flat fee and/or master points via producer agreement |
| Topliner who wrote the melody/lyrics | Yes | Publishing royalties based on split percentage |
| Session musician (played as directed) | No | Session fee, possibly master points |
Mistake #4: Sloppy Metadata That Breaks the Pipeline
A split sheet feeds every system downstream: PRO registration, Songview, distributor metadata, streaming platforms, royalty payments. A single error at the beginning cascades through the entire chain.
If your split sheet has "John Smith" but your PRO registration says "Jon Smith," that's a mismatch. If your IPI number has a transposed digit, royalties collected internationally may never reach you.
$397M
in historical unmatched royalties still being worked through by the MLC
The MLC says the original pool of historical unmatched royalties transferred by DSPs was later adjusted from roughly $427 million to roughly $397 million after CRB rate finalization. That money does not disappear because the songs failed creatively. It gets stuck because the data failed administratively. The most common culprits on split sheets:
- Misspelled legal names — "Johansson" vs. "Johansen" is enough to break a match
- Wrong or missing IPI numbers — without this identifier, international royalties have nowhere to go
- Inconsistent song titles — working titles that never got updated
- Missing publisher information — the publisher's share may go uncollected
- Wrong PRO affiliation — if a writer switched PROs but the split sheet wasn't updated
Mistake #5: Registering Conflicting Shares With Your PRO
You register your song with ASCAP claiming 60%. Your co-writer registers with BMI claiming 50%. That's 110% — and the moment the databases cross-reference through Songview, royalties freeze.
When a pay source receives claims over 100%, they suspend all royalty payments for that song until every party resolves the discrepancy. And it works both ways — if you register 40% and your co-writer registers 40%, the remaining 20% sits in limbo uncollected.
The fix: designate one person as the PRO submitter on the split sheet. One person coordinates the registration so all shares match. This single step eliminates conflicting claims.
Mistake #6: Forgetting the Letter of Direction
You have a signed producer agreement — 3 points on the master and 15% of the publishing. The song gets released through a label. Royalties flow. And you get nothing.
Why? Because you never sent a Letter of Direction (LOD) to the label. Even though your contract is with the artist, the label cuts the checks. Without an LOD, they have no instruction — and no obligation — to pay you.
An LOD directs the label to pay the producer's royalty share directly, send royalty statements, and apply the agreed recoupment terms. Send it as soon as the song is accepted for release — not months later when you realize you haven't been paid.
Mistake #7: Not Planning for Sync Clearance
Sync licensing is one of the most lucrative revenue streams for independent artists. But to license a co-written song, you need written approval from every co-owner of the composition. Not most of them. All of them.
Your split sheet establishes who needs to approve. A collaboration agreement can go further with pre-clearance terms: conditions under which any co-writer can approve sync on behalf of the group.
At minimum, your split sheet should include current contact information for every contributor, and contributors should commit to keeping it updated.
How to Protect Yourself
Every mistake above is preventable.
Fill out the split sheet in the studio. Before anyone leaves. Use our split sheet guide and interactive calculator if you need a starting point.
Verify every contributor's information. Legal name, current PRO, IPI number, publisher details. An IPI lookup takes 30 seconds on ASCAP's ACE database or BMI Repertoire.
Designate one PRO submitter. One person coordinates registration so all shares match.
Separate publishing from master ownership. Only songwriters go on the split sheet. Master points go in a producer agreement.
Get the Letter of Direction signed early. Send it as soon as the track is accepted for release.
Include contact information and keep it current. Protects future sync opportunities.
Cross-reference your registrations. Check Songview to verify shares add up to 100%.
