Split Sheets & Co-Writing Agreements
A split sheet is an agreement among co-writers of a musical composition documenting each writer's ownership percentage of the copyright. Split sheets establish who is entitled to what percentage of publishing income, songwriter royalties, mechanical royalties, and performance royalties. Without a signed split sheet, ownership disputes among collaborators lack a written record, and courts apply joint authorship presumptions that may not reflect the parties' actual intent. Co-writing agreements can be more detailed — addressing not just percentage splits but also how future licensing decisions are made, credit requirements, and what happens when one co-writer signs with a publisher.
Split sheet disputes are among the most common — and most preventable — conflicts in music law. When multiple writers collaborate without documenting their ownership percentages before a song becomes commercially significant, the resulting disputes are expensive, uncertain, and destructive to professional relationships. The moment to execute a split sheet is before the recording session begins — not after the placement or sync deal arrives.
Defines joint works as works prepared by two or more authors with the intention that their contributions be merged into inseparable or interdependent parts — the legal framework that applies when split sheets are absent.
Co-authors of a joint work are co-owners of the copyright — each can license the work non-exclusively without the others' consent, but must account to co-owners for profits. This default can be modified by split sheet agreements.
Transfers of copyright ownership must be in writing — a signed split sheet is the appropriate instrument for documenting ownership percentages among co-writers.
The absence of split sheet documentation is epidemic in the independent music community — and the consequences become apparent only when a song achieves commercial significance. The MLC and PROs require clear ownership documentation to distribute royalties, and unresolved splits create payment delays and liability exposure for labels and publishers. Session-based and producer-songwriter collaboration models have increased the frequency of unresolved splits as more parties contribute to a single recording.
Execute split sheets before the recording session begins — ideally as the first document signed at any collaborative writing session.
Split sheets should be specific: include the full legal name of each writer, their PRO affiliation (ASCAP, BMI, SESAC), their publishing company (if any), and their percentage (totaling exactly 100%).
Address the producer's role explicitly — if the producer is contributing musical elements (melody, hooks), they may be a co-writer. Clarify this before the session.
A split sheet that says '50/50' without specifying which writer owns which half of the publishing can create problems if the writers are affiliated with different publishers — specify both the writer's share and the publisher's share for each co-writer.
Register the confirmed split with both ASCAP/BMI and the MLC as soon as the song is finalized — delayed registration delays royalty payments.
Execute split sheets before the recording session — never after the song is commercially successful.
Absent a written agreement, equal ownership is presumed among joint authors regardless of relative contribution.
Any co-owner of a joint work can grant non-exclusive licenses without the other co-owners' consent — but must account for profits.
Split sheets should specify both the songwriter's share and the publisher's share for each co-writer — not just the overall percentage.
Producers who contribute melody or hooks may be co-writers entitled to a publishing split — clarify this before the session begins.
At minimum: song title, date of creation or recording session, each writer's full legal name, each writer's contact information, each writer's PRO affiliation, each writer's ownership percentage (totaling 100%), each writer's publishing entity (if applicable), and dated signatures of all co-writers.
Under joint authorship principles, equal ownership is presumed among co-authors absent an agreement. Courts look at evidence of intent, contribution, and prior dealings to establish actual ownership. Litigation is expensive and outcomes are uncertain — the best result is usually a negotiated settlement.
Not automatically — it depends on the producer's creative contribution. A producer who contributes only beats, production, or instrumentation without melodic or lyrical composition is typically not a co-writer. A producer who contributes melodies, hooks, chord progressions, or lyrics may have a valid co-writer claim. The split sheet should address this explicitly before the session.
