The Complete Guide to Song Split Sheets

Split sheets sound administrative until you look at the money that goes missing without them:

$397M

historical unmatched royalties still sitting at the MLC after rate adjustments

The Mechanical Licensing Collective says the original pool of roughly $427 million in historical unmatched royalties was later adjusted to roughly $397 million after CRB rate finalization. A lot of that missing money starts with incomplete songwriter and ownership data.

The document that prevents this is a split sheet. If you're making music with anyone else, it's the most important piece of paper in your workflow.

What Is a Split Sheet?

A split sheet identifies every contributor to a song and establishes each person's ownership percentage. It determines who gets paid — and how much — whenever a song generates revenue.

A split sheet covers the composition (lyrics, melody, arrangement), not the sound recording. These are two separate copyrights, which we'll break down below.

What It Must Include

• Song title (and any working titles)
• Legal names of all contributors
• Ownership percentage for each (must total 100%)
• PRO affiliation (ASCAP, BMI, SESAC, etc.)
• IPI/CAE number — your unique 9-digit PRO identifier
• Publisher information (if applicable)
• Description of contribution (lyrics, melody, music, arrangement)
• Whether a copyrighted sample was used
• Dated signatures from all parties

Why They Matter More Than Ever

The Mechanical Licensing Collective (MLC) received roughly $427 million in historical unmatched royalties, later adjusted to roughly $397 million — money generated by songs that couldn't be connected to the right songwriters.

Why? Incomplete or incorrect metadata — missing songwriter names, wrong percentages, absent IPI numbers. The root of that problem is often the absence of a split sheet.

The Legal Default You Don't Want

Under US copyright law, a song created by multiple people is automatically a "joint work." Without a written agreement, all co-authors share equal ownership regardless of actual contribution.

Two writers? 50/50. Three writers? 33.3/33.3/33.3 — even if one person wrote the entire melody and another contributed a single line. A split sheet overrides this default with whatever you actually agree on.

Publishing Splits vs. Master Splits

Every commercially released song has two separate copyrights:

1. The composition (publishing) — lyrics, melody, and musical structure
2. The sound recording (master) — the specific recorded performance

Each generates its own revenue and can have different ownership splits.

Publishing Splits

Publishing royalties are divided into two halves:

• Writer's share (50%) — paid directly to the songwriter by their PRO. Cannot be transferred to a publisher.
• Publisher's share (50%) — goes to the songwriter's publisher (or back to the songwriter if self-published)

When a split sheet says "Writer A: 60%, Writer B: 40%," that applies to the entire composition — both the writer's and publisher's share.

Where Producers Fit

Scenario	Typical Publishing Split
Hip-hop/pop producer (created the beat)	50% of publishing
Indie/singer-songwriter producer	15-25% of net royalties
Mix/mastering engineer	0% (paid flat fee)
Session musician (no songwriting)	0%

The key distinction: a producer who creates the beat, chord progression, or melodic structure is a songwriter and belongs on the split sheet. A producer who mixes or engineers existing material is compensated through flat fees or master points.

Master Splits (Producer Points)

Separately from publishing, producers often receive "points" on the master — typically 2-5 points (percentage points of master royalties). These are negotiated in a producer agreement, not on the split sheet.

How to Create a Split Sheet

When to Do It

In the studio, before anyone leaves. What feels like an obvious 60/40 during the session becomes a contested argument three months later when the song's about to release.

The Process

1. List all contributors who contributed to the composition — lyrics, melody, harmonic structure, arrangement.
2. Agree on percentages. Must total exactly 100%. Some teams default to equal splits ("Nashville method"); others split by contribution. Neither is wrong, but everyone must agree.
3. Fill in details. Legal name, PRO affiliation, IPI number, publisher name, contact info for each contributor.
4. Note any samples. Uncleared samples can invalidate the entire arrangement.
5. Sign and date. Digital signatures are legally valid. Every contributor gets a copy.

From Split Sheet to Royalty Check

Here's the pipeline that turns a signed split sheet into actual payments:

If your split sheet says 60/40 but your PRO registration says 50/50 — or if your co-writer registered different percentages — Songview flags a conflict and freezes all royalty payments until resolved. If your distributor has different metadata than your PRO, streaming royalties end up in the black box.

The split sheet is the single source of truth every other system depends on.

Common Mistakes

1. Relying on Verbal Agreements

"We agreed on 60/40" means nothing without a signature. PROs cannot verify verbal agreements.

2. Waiting Until After Release

By the time a song is gaining traction, the person who was happy with 20% may feel very differently.

3. Percentages That Don't Add to 100%

If you register 60% and your co-writer registers 50%, PROs will hold all royalties until the conflict is resolved — which can take months.

4. Confusing Publishing and Master Splits

A producer with 3 master points should not also be listed for 3% on the publishing split sheet (unless they contributed to the songwriting). These are separate copyrights.

5. Missing IPI Numbers

Your IPI is how PROs identify you across borders. Without it, royalties collected internationally may never reach you.

Digital Tools for Managing Splits

Several platforms handle split sheet creation and signing digitally: Splits App, SplitSheets.app, SongSplits, and musicsplits.io.

These tools solve creation and signing — but splits are only one piece. The real challenge is keeping split information connected to your songs, recordings, metadata, contacts, and release status. When that information lives in separate apps and spreadsheets, things fall through the cracks.

What to Do Next

• Next session: have the split conversation before anyone leaves. Fill out a split sheet, get signatures.
• Existing catalog: audit unreleased songs. Any collaboration without a split sheet is a liability.
• PRO registrations: cross-reference registered songs with your split sheets. Fix mismatches before they freeze royalties.
• Workflow: pick a system and use it consistently for every song.
