How to split song ownership
Five steps from session to signed agreement.
Agree on contributions
Before the session ends, discuss who did what. Lyrics, melody, production, arrangement — every contribution matters.
Choose a split method
Equal splits work when everyone contributed evenly. Manual splits let you set exact percentages. Weighted splits calculate ownership based on each person’s input across categories.
Calculate percentages
Use this calculator to determine each collaborator’s ownership share. The total must equal 100%.
Document in a split sheet
A calculation is not an agreement. Create a proper split sheet with names, roles, percentages, and signature lines.
Get signatures or verify on CAZEN
Print and sign the split sheet, or use CAZEN to create a co-signed, timestamped Vault record that’s tamper-proof and legally weighted.
Frequently Asked Questions
How do you split ownership of a song?
Song ownership can be split equally among all contributors, manually assigned by agreement, or calculated based on each person's contribution to lyrics, melody, production, and arrangement. The key is to agree on splits early and document them in a split sheet.
What is the standard songwriter-producer split?
There is no universal standard. Common arrangements include 50/50 between songwriter and producer, but splits vary widely based on contribution, negotiation, and context. Use a split calculator to explore different methods before deciding.
Should splits always equal 100%?
Yes. Total ownership of a song must equal 100%. Each collaborator’s percentage represents their share of royalties, publishing rights, and other income from the work.
What’s the difference between a split calculator and a split sheet?
A split calculator helps you figure out what the percentages should be. A split sheet is the actual document that records the agreed-upon splits with signatures. Use the calculator first, then create a split sheet to make it official.
What does ‘weighted by contribution’ mean?
Weighted splitting lets each collaborator rate their contribution to lyrics, melody, production, and arrangement. The calculator then computes ownership percentages proportional to each person’s total contribution score. This method is useful when contributions are uneven across categories.
