A music split sheet is a short written agreement that says who wrote a song and what percentage each songwriter owns. It takes five minutes to fill out, and it can save you months of lost royalties and awkward arguments later. If you write with anyone, even a close friend, every song needs a songwriter split sheet. This guide explains what goes on one, what happens without one, and how your splits flow into every registration that pays you.
What a split sheet is
A split sheet is a simple document, usually one page, that records:
- The song title
- Every person who contributed to writing the song
- The percentage of the composition each writer owns
- Contact and royalty details for each writer
- Signatures from everyone
That is it. It does not need to be a long contract. What matters is that it is written down, it is agreed, and everyone signs.
What a split sheet covers
A split sheet is about the composition: the melody and the lyrics. It says who owns the song itself.
It usually does not cover the master recording. Ownership of the recording, producer points, and payment for session work are often handled in separate agreements. Keep that difference in mind. You own two things when you release a song, and we call that owning 200%. The Royalty Map shows which organizations pay on each side.
Why it matters so much
Almost every registration that pays songwriters asks for the same thing: a list of writers and their shares adding up to 100%. Your PRO asks for it. The MLC asks for it. The Copyright Office asks who the authors are. If you and your co-writers disagree, money can be held while the conflict gets sorted out.
A split sheet is how you make sure everyone registers the same numbers.
What happens without one
Skipping the split sheet feels harmless in the moment. The session went great, everyone is friends, and paperwork kills the vibe. Here is what can happen later.
Conflicting registrations
You register the song as 50/50. Your co-writer registers it as 60/40 in their favor. Now the total claimed is more than 100%. Collection organizations often hold money on songs with conflicting claims until the writers resolve it.
Forgotten contributors
Six months later, nobody remembers whether the person who suggested the bridge melody counts as a writer. Memories fade, and people remember their own contributions more generously.
Broken friendships
Money changes how people remember things. A clear agreement made in the room, while everyone is happy, protects the relationship as much as the royalties.
Registrations that never happen
Some artists hold off registering because they are not sure what to put down. Every month a song is not registered is a month its royalties may go unmatched. If you already suspect this, run the free Missed Royalties Check.
What goes on a split sheet (names, IPIs, PROs, percentages)
Here is a complete checklist. The more of this you capture in the room, the easier every registration becomes.
Song information
- Song title (and working titles or alternate titles)
- Date of the writing session
- Location or session name
- Performing artist, if known
For each writer
- Legal name
- Stage or writer name, if different
- Email and phone
- PRO affiliation (for example BMI, ASCAP, or another society)
- IPI number, the unique songwriter ID you get when you join a PRO
- Publisher name and publisher IPI, if they have one, including their own publishing entity
- Contribution (music, lyrics, or both), optional but helpful
- Ownership percentage of the composition
The total
All percentages must add up to exactly 100%. Not 99%, not 101%. Double check the math before anyone signs.
Signatures and date
Every writer signs and dates the sheet. A digital signature works too, as long as everyone agrees to it.
If a co-writer is not yet in a PRO, leave space for their IPI and follow up. See BMI vs ASCAP if they need help choosing.
Writer share vs publisher share explained
This is where a lot of confusion lives, so let's slow down.
The composition is split into two sides
When a PRO pays performance royalties, it generally splits the money into two halves:
- The writer share. Paid to the songwriters.
- The publisher share. Paid to the publishers of the song.
How that relates to your split sheet
Your split sheet percentages usually describe how each writer shares in the song. If you own 50% of the song, you typically get 50% of the writer share, and your publisher (or your own publishing entity) is typically entitled to 50% of the publisher share.
If you do not have a publisher
Many independent songwriters set up their own publishing entity with their PRO so the publisher share comes to them. If you do not, how that share is handled depends on your PRO's rules. Read BMI or ASCAP guidance directly.
Keep it simple on the sheet
You do not need to split writer and publisher percentages separately on a basic split sheet. Record each writer's ownership of the song, and note their publisher. The organizations will apply the writer and publisher sides.
When to fill it out (before the session ends)
The best time to fill out a split sheet is before everyone leaves the room, or before the video call ends.
Why then
- Everyone remembers who did what.
- Everyone is in a good mood.
- Nobody has a reason yet to feel like they deserve more.
How to make it painless
- Keep a blank split sheet template on your phone or laptop.
- Say at the start of the session, "We will do a quick split sheet before we wrap."
- Default to an even split among everyone in the room unless the group agrees otherwise. Many writers use even splits as a simple starting point, but it is your call.
- Take a photo or save the PDF, and email it to everyone that day.
If you forgot
It is not too late. Reach out to your co-writers now, agree on the splits in writing, and have everyone sign. An agreement made later is far better than none.
How splits flow into MLC, PRO, and copyright registrations
Once you have a signed split sheet, you use the same numbers everywhere. Consistency is what lets royalties match cleanly.
Your PRO
When you register the song with your PRO, you list every writer, their PRO, their IPI, and their share. Each writer can register the song at their own PRO. If everyone uses the numbers from the split sheet, the registrations agree.
The MLC
The MLC pays US digital mechanical royalties. When you register the work, you enter every writer, their IPI, and their share. Shares that total more or less than 100% can cause problems. Our MLC registration guide walks through it.
The Copyright Office
When you register the composition, you list the authors and the claimants. Your split sheet tells you exactly who to include. See how to copyright a song for the eCO steps.
Your distributor
Some distributors ask for songwriter credits and publishing info. Use the same names.
Recording side
SoundExchange and your distributor pay on the recording, not the composition, so your split sheet percentages do not usually apply there. Master ownership is a separate agreement.
How Royalty Lock uses your splits
In Royalty Lock you enter your writers, IPIs, PROs, and percentages once. The app checks that shares total exactly 100% before anything else happens. Then the AI uses those same numbers in every file and form it preps for your PRO, The MLC, and copyright. You submit each one under your own login. We never log into your accounts. See How it works, or start with the pillar guide on how to register a song everywhere it earns.
Tips for tricky situations
Producers who contribute to the composition
If a producer helps write the melody, chords, or lyrics, they may be a songwriter on the split sheet. If they only work on the sound of the recording, their compensation is often handled separately. Talk about it openly.
Samples and interpolations
If your song uses someone else's composition, the original writers may be owed a share. Clear it before release, and reflect it on the split sheet.
Changing splits later
If everyone agrees to change the splits, make a new signed sheet and update every registration to match.
A simple split sheet template
You can copy this layout into a note or document and fill it out at every session.
Song title: ______________________ Date: ______________ Session location: ______________
Writer 1 Legal name: ______________ Writer name: ______________ PRO: ______________ IPI: ______________ Publisher: ______________ Publisher IPI: ______________ Share: ______ % Signature: ______________
Writer 2 (repeat the same fields for each writer)
Total: 100 %
Keep a copy for every writer, and store the signed version somewhere safe, like a shared folder.
Split sheet etiquette
Talking about money with creative partners can feel awkward. A few habits make it easier for everyone.
- Bring it up early. Mention the split sheet at the start of the session so nobody is surprised at the end.
- Keep it friendly. Frame it as protecting everyone, not as distrust.
- Talk about contribution honestly. If someone feels their part was bigger or smaller, discuss it calmly before anyone signs.
- Do not register until it is signed. Registering your own numbers before agreement is how conflicts start.
- Share copies the same day. Everyone should leave with the same document.
Writers who do this every time build a reputation as easy, professional collaborators. That makes people want to write with you again.
