Quick summary

A co-publishing agreement is a contract in which a songwriter shares ownership of the publisher's share of their compositions with a publisher, while retaining the full writer's share. This is the most common publishing deal structure for established songwriters working with major or independent publishers. It sits between a full publishing deal, where the publisher takes the entire publisher's share, and an administration deal, where the publisher takes no ownership at all and simply collects royalties for a fee. This article defines what a co-pub agreement is, how the writer's share and publisher's share divide publishing income, what the publisher does in exchange for their share, and the key questions an independent songwriter should consider before signing.

Key takeaways

Publishing income is split into a writer's share and a publisher's share. In a co-pub deal, the writer keeps the full writer's share and splits only the publisher's share.
A co-pub deal transfers partial copyright ownership to the publisher. An admin deal does not transfer any ownership.
A full publishing deal gives the publisher the entire publisher's share and usually full copyright control. A co-pub deal gives them half of it.
In exchange for their share, a publisher typically offers an advance, active sync pitching, co-writing connections, and global collection infrastructure.
The retention period, how long after the deal ends the publisher collects on songs written during the term, is often more consequential than the royalty split itself.

Definitions

Publishing: The ownership and administration of the underlying musical composition, the melody and lyrics, as distinct from any particular recording of it.
Publishing administrator: A company or service that registers compositions, collects royalties from multiple sources including The MLC and PROs, and remits them to songwriters in exchange for an administrative fee rather than copyright ownership.
PRO: Performance rights organization. A collective such as ASCAP or BMI that licenses public performance of compositions and collects performance royalties on behalf of songwriters and publishers.

Three deal structures, one underlying question

Independent songwriters who want professional support for their compositions face three distinct deal structures: a full publishing deal, a co-publishing agreement, and an administration deal. The terms sound similar and are often confused, but they answer a single underlying question in three different ways: how much of your composition's copyright are you transferring to someone else?

Publishing is the ownership and administration of the underlying musical composition. Publishing income, broadly, divides into a writer's share and a publisher's share. Understanding what each share represents is the prerequisite for understanding any publishing deal.

The writer's share and the publisher's share

When a composition generates performance royalties, those royalties are split between the songwriter and the publisher. The writer's share is the portion that goes directly to the songwriter. As BMI explains in its royalty FAQ, one half of the total performance royalty is designated for the songwriter or composer, and the other half is designated for the publisher or copyright holder. The writer's share belongs to the person who wrote the song, and under BMI's structure it cannot be assigned to a publisher.

The publisher's share is the other half. When a songwriter has no publisher, the PRO pays both halves to the songwriter. When a songwriter has a publisher, the publisher's share flows to that publisher, who may then pay a portion back to the songwriter depending on the deal terms. A songwriter who owns their own publishing entity collects both shares themselves.

Mechanical royalties follow a related but distinct structure. As Songtrust explains, mechanical royalties generate only a publisher's share that is allocated to whoever owns or administers the publishing copyright.

What a co-publishing agreement is

A co-publishing agreement is a contract in which the songwriter assigns part of the publisher's share to a publisher while retaining the full writer's share. In the most common structure, the songwriter assigns half of the publisher's share, keeping 50 percent as their writer's share plus 25 percent as their retained portion of the publisher's share, for a total of 75 percent of all publishing income. The publisher receives the remaining 25 percent of total income, along with co-ownership of the copyright.

As Songtrust outlines, in a co-publishing agreement the songwriter typically gives away 50 percent of the publisher's share. The songwriter retains 100 percent of the writer's share and 50 percent of the publisher's share, meaning 75 percent of total publishing royalties. The publisher, holding the other 50 percent of the publisher's share, typically administers the entire composition and pays the songwriter their share on a regular schedule.

This is different from a full publishing deal, where the songwriter assigns the entire publisher's share to the publisher, retaining only the writer's share, and typically relinquishes copyright control as well. In a co-pub deal, the songwriter retains partial copyright co-ownership alongside the publisher.

How a co-pub deal differs from an administration deal

The structural difference between a co-pub and an admin deal is ownership.

In an administration deal, the publishing administrator takes no copyright ownership. The songwriter retains 100 percent of both the writer's share and the publisher's share, and pays the administrator a fee, typically in the range of 10 to 25 percent of publishing collections, for registration and royalty collection services. As Songtrust describes, in an administration deal the songwriter keeps 100 percent ownership of the copyright and writer's share, giving away only a percentage of the publisher's share as an administrative fee for a defined term, usually one to three years. When the term ends, the relationship ends with it.

In a co-pub deal, the publisher acquires ownership of a portion of the copyright. That ownership interest does not automatically expire when the deal term ends. Songs written during the deal term are typically subject to the publisher's retained ownership for an extended period after the term, sometimes for the life of copyright, depending on how the retention period is negotiated.

The practical implication is significant. An admin deal is a service relationship. A co-pub deal is a co-ownership relationship with long-term consequences for how the catalog is controlled and monetized.

What the publisher provides in exchange

A co-pub deal requires the publisher to provide services that justify the permanent ownership transfer. According to the National Music Publishers' Association, publishers work to pair talented songwriters with artists and industry professionals, pitch songs for use in film, television, and advertising, license the right to use compositions, collect fees, and distribute a portion to the composer.

In practice, the value of a co-pub deal depends on how actively the publisher executes these functions. The services typically offered in exchange for the co-pub split include an advance against future royalties, active sync pitching using established relationships with music supervisors, facilitated co-writing sessions with other signed writers, and global collection infrastructure through sub-publishing relationships in international territories where an independent songwriter would otherwise have limited reach.

The advance is the most immediate and tangible benefit. Under a co-pub deal, the songwriter receives money upfront, but that advance is recouped from the publisher's portion of future royalties before additional distributions are made. The songwriter's share of royalties flows to them directly, separate from the recoupment clock.

What an independent songwriter should weigh

The core trade-off in a co-pub deal is capital and industry access today in exchange for permanent partial ownership. That exchange can be favorable or unfavorable depending on where a songwriter is in their career and what they actually need.

Several terms deserve close attention beyond the royalty split itself.

The retention period defines how long after the deal term ends the publisher continues to hold their ownership interest in songs written during the term. A retention period of the full copyright term, which extends for the life of the author plus 70 years under U.S. copyright law, is a permanent transfer. Some deals negotiate for shorter retention periods or include reversion clauses. The duration of the retention period is often more consequential to long-term income than the percentage split itself.

The minimum delivery commitment is a clause requiring the songwriter to deliver a set number of commercially released compositions during the deal term. Failing to meet this commitment can trigger penalties or extend the term.

Pipeline songs are compositions written before the deal that have not yet been commercially released. Publishers sometimes attempt to include these in the deal's scope. A songwriter who has an existing catalog of unreleased material should confirm precisely what compositions are covered.

A songwriter who has no existing publishing income and needs both capital and professional development may find that a co-pub deal, with a reputable publisher who actively works the catalog, creates opportunities that would not otherwise exist. A songwriter who is already generating meaningful publishing revenue and can manage their own sync relationships may retain significantly more income over time through an admin deal that keeps copyright intact.

Registering compositions with a PRO such as ASCAP or BMI to collect performance royalties, and separately with The MLC to collect streaming mechanical royalties, remains essential under any deal structure. As discussed in master royalties vs publishing royalties, the publishing side of the income equation requires active registration to collect, regardless of who holds the publishing rights. A co-pub deal does not make those registrations automatic. Confirming that a prospective publisher handles full registration across all pay sources is a basic due diligence step before signing.

Frequently asked

What is a co-publishing agreement?

A co-publishing agreement is a contract in which a songwriter assigns a portion of the publisher's share of their compositions to a publisher, while retaining the full writer's share and typically half of the publisher's share. In the conventional structure described by Songtrust and others, the songwriter keeps 75 percent of total publishing income, combining their 50 percent writer's share with 25 percent of the publisher's share, while the publisher keeps the remaining 25 percent. The publisher receives copyright co-ownership and, in exchange, provides an advance, administrative services, sync pitching, and access to their professional network.

How does a co-publishing deal differ from an administration deal?

The key difference is ownership. In a co-publishing deal, the publisher acquires co-ownership of the copyright in songs written during the term. That ownership interest typically continues after the deal ends. In an administration deal, the publisher takes no ownership at all. The songwriter retains 100 percent copyright ownership, and the administrator simply registers and collects royalties in exchange for a percentage fee, typically 10 to 25 percent, for the duration of the term only. Once an admin deal ends, the administrator's relationship to your catalog ends. Under a co-pub deal, the publisher may retain their ownership interest and continue collecting their share indefinitely, depending on the contract terms.

What does a publisher actually do in a co-publishing agreement?

A publisher in a co-pub deal typically provides an advance against future royalties, registers compositions with performing rights organizations and The MLC, pitches songs for sync placements in film, television, and advertising, facilitates co-writing sessions, and uses their global sub-publishing relationships to collect royalties in territories where an independent songwriter would have limited reach. As the National Music Publishers' Association describes, publishers license compositions for reproduction, public performance, synchronization, and other uses, then split the collected fees with songwriters. The scope of these services and how actively they are delivered varies significantly by publisher.

Should an independent songwriter pursue a co-publishing deal or an admin deal?

It depends on what the songwriter actually needs. A co-pub deal offers an advance and active industry support in exchange for partial copyright ownership that is often permanent. An admin deal keeps full ownership with a lower fee and shorter commitment, but provides no advance and typically no active sync pitching or creative development. As Songtrust outlines, songwriters who are already generating meaningful publishing income and do not need an advance often retain more long-term value through an admin deal. Songwriters earlier in their career who need the industry relationships and capital that a publisher provides may benefit from a co-pub deal despite the permanent ownership transfer.
