A split sheet is a document that records how ownership of a song is divided among all contributors. It captures each person’s name, role, PRO affiliation, IPI number, and ownership percentage — and the percentages must add up to 100%.

Split sheets typically cover the composition (the underlying melody and lyrics). They may also cover the master recording (the specific recorded version), though master ownership is often handled separately in producer agreements.

Anyone who contributed to the melody, lyrics, or arrangement of the song should be listed. This includes co-writers, producers who contributed musical elements (hooks, chord progressions, melodic riffs), and lyricists. Beat producers who sell or license a pre-made beat without further creative contribution may be listed differently — see Article 6 on beat licenses.

Each contributor’s entry typically includes:

• Legal name and stage name
• Role (e.g., composer, lyricist, producer)
• PRO affiliation (ASCAP, BMI, SESAC, GMR)
• IPI number (assigned by their PRO)
• Ownership percentage
• Signature

A split sheet is a record of agreement. To carry legal weight it must be signed by all parties. An unsigned document is evidence of intent but is not enforceable as a contract. Some collaborators also include a brief agreement clause confirming that all parties consent to the stated splits — this strengthens its standing if a dispute arises.

A split sheet does not register your copyright with the US Copyright Office. Registration is a separate step — see Article 8 on copyright basics.

In the United States, copyright protection exists automatically the moment an original work is fixed in a tangible form (a recording, a written lead sheet, a saved file). But registration with the Copyright Office provides critical legal advantages, including the right to sue for statutory damages. A split sheet does not substitute for that.

Best practice: create the split sheet before recording begins — or at minimum, before the session ends. Waiting until a song becomes commercially valuable is when disagreements surface and memories diverge. An agreed-upon split when no money is involved is far easier to achieve than one negotiated after a placement.
