What Is a Book Collaboration Agreement?
A collaboration agreement defines the parties’ goals and sets boundaries, including who owns and controls intellectual property rights. Key provisions address copyright ownership, compensation, creative control, credit, and dispute resolution. How these are negotiated depends largely on whether you are hiring a writer or entering into a true joint authorship arrangement, industry practice, and legal guidance.
Who Owns the Copyright in Co-Authored Books?
In the absence of a written agreement, collaborators are generally deemed joint authors. Each owns an equal, undivided 50% interest in the copyright and the income it generates. The Copyright Act, a federal statute, sets these default rules, and courts do not adjust ownership shares based on reputation, effort, or experience.
The main exception is the work made for hire doctrine. If a work is created as a “work for hire,” the hiring party is considered the author and owns the copyright outright. This status, however, requires a written agreement expressly stating the work is “made for hire.” Courts view after-the-fact attempts to recast a project as a work for hire with skepticism, often regarding them as attempts to strip creators of their rights.
For joint authorship to exist, there must be a shared intent. The Copyright Act defines a joint work as one “prepared by two or more authors with the intention that their contributions be merged into inseparable or interdependent parts of a unitary whole.” Editors, researchers, or others who contribute without this mutual intent are not considered co-authors.
When a joint work exists, either author may publish or license non-exclusive rights without the other’s consent. However, granting exclusive rights requires unanimous agreement. If there is no written contract—or the contract fails to address licensing—an uncooperative co-author (or their heirs) can block a sale or exclusive license.
Fortunately, these default rules can be overridden. A written collaboration agreement can clarify ownership percentages, revenue splits, decision-making authority, credit, and procedures for resolving disputes—thereby avoiding costly and disruptive conflicts down the road.
How to Structure a Ghostwriter Writer Agreement: Rights and Payment Terms
Equal sharing of rights should be reserved true joint authorship. to be joint authors. This is often what people have in mind (even if they don’t use the legal term) when they bring in a ghostwriter or independent contractor.A "work for hire" is probably what many people would have contemplated had they thought about it when hiring a ghostwriter or independent contractor. With a work-for-hire, the commissioning or hiring party, not the writer, is considered the author and owner of one hundred percent of the work.
A formal ghostwriter agreement should contain the legal phraseology, "the parties expressly agree that the work shall be considered a work made for hire." After-the-fact attempts to classify a work as a work for hire are not recognized in all states. For this reason, it's considered best practice to include a backup copyright assignment in work for hire agreements.
Essential Contract Terms for Book Collaborations
Responsibilities and Deliverables. Be specific about what must be delivered and when. When you engage a writer to help with a nonfiction book, the writer typically will prepare a book proposal before completing the manuscript. A book proposal is a detailed overview of the book, it contains the author’s credentials and information about how the book can be marketed, plus one or two sample chapters.
In the case of a memoir, it's also important to lay out what the writer is allowed to disclose. Is their job to put the best face on the subject of the story without resorting to blatant deception? How many words? The average word count for a general interest nonfiction book clocks in between 50,000 to 60,000 words.
In true collaborations, if one author has greater publishing experience, the parties may agree to designate that person as the point person to negotiate with agents and publishers. The less experienced collaborator can condition their approval of any publishing contract on the inclusion of certain minimum acceptable terms.
Advances, Royalties, and Payment Schedules. In traditional publishing, authors receive an advance against future royalties—typically paid in two or three installments (for example, half on signing and half on delivery and acceptance of the manuscript). An advance is recoupable but not returnable; in other words, it functions like a loan against the book’s future earnings.
For ghostwriting arrangements, deferring part of the fee can help the hiring party engage a more experienced writer without paying large sums upfront. Typically, a portion of the writer’s fee is paid when the agreement is signed, with additional payments tied to milestones such as delivery of a proposal, draft chapters, or the final manuscript.
The agreement should also address what happens if either party withdraws. For example, if the subject abandons the project, the contract can specify that the writer keeps any payments already received. This type of provision softens the financial impact of a failed collaboration.
Finally, if the writer is to share in royalties or licensing income, the agreement must spell out how proceeds will be divided from the sale or license of the book and related rights (e.g., film, television, or live stage). In practice, a ghostwriter’s or collaborator’s percentage from book royalties may differ from their share of film or television rights—especially in the case of memoirs.
Author Credit. By some estimates, up to 70% of nonfiction books are ghostwritten. For example, it is widely believed that Theodore Sorenson wrote John F. Kennedy's Pulitzer Prize-winning book, "Profiles in Courage,” for which JFK took both the prize and sole credit.
Common writing credit formats:
- "by Subject and Writer"
- "Subject with Writer"
- "as told to Writer"
- Ghostwritten (subject's name only)
Because ghostwriters typically forgo public recognition, they may negotiate for higher fees to compensate for the lack of career-building visibility that comes with cover credit. From the publisher’s perspective, the order, size, and prominence of names on the cover and title page can influence marketing and sales, which is why the agreement should explicitly address how credit will be handled.
Copyright Ownership. In the event of a creative divorce, except in the case of a true work for hire, it may be possible to separate out each author's discrete contribution and transfer those rights to the original contributor. One permutation of this is, "the copyright ownership of the material provided by each party shall revert to and revest in the contributing party with the result that neither party shall be permitted to use the materials contributed by the other without such others written permission."
Death, Disability and Succession Planning. Agreements should include rules for hiring someone to complete the manuscript if either party dies, becomes disabled, or an intractable disagreement arises. If the commissioning party dies the person designated in their will or estate plan to manage their literary property, whether an a general executor, or literary executor, can step into their place to oversee completion of the work and make related business decisions. Because general executors or trustees are not always experienced in publishing, the agreement may name an alternate decision-maker or set out guidelines to ensure continuity and protect the interests the departing author.
When one party becomes disabled, the agreement should distinguish between temporary and permanent disability. If the disability makes it impossible for someone to continue (e.g., long-term incapacity), the agreement should address (i) whether a substitute writer may be engaged, (ii) how compensation to the disabled party (or their heirs) will be adjusted, and (iii) whether and how the substitute will receive credit.
For works requiring updates (such as textbooks), include provisions allowing the non-departing authors to revise the work and reduce compensation paid to the departing author or their heirs. Specify whether the person hired to complete the work, or undertake future revisions can receive author credit and what form it will take.
Decision-Making Authority and Editorial Control. Unlike a ghostwriting agreement, where one party is essentially hired to provide writing services, a true collaboration agreement assumes joint ownership and shared responsibility for both the business and creative aspects of the work. Control of business affairs (i.e., who is responsible for seeking offers and approving contracts) and editorial matters (i.e., who has the authority to approve the manuscript) are central issues. The parties may decide that unanimity is required for certain decisions (e.g., approval of the initial publishing contract). If one collaborator retains approval rights over the manuscript, the agreement should require them to notify the other party within X days after delivery if the manuscript is acceptable. If not acceptable, they should provide written comments or recommendations on what improvements are needed. Requiring detailed editorial reasons within a set timeframe creates a safeguard against terminating a writer merely for convenience.
Representations, Warranties and Indemnification. From a writer-for-hire's perspecitve, it's important to have the subject promise that they will:
Provide access to pertinent documents (diaries, memorabilia, business papers)Provide reasonable access to themselvesUse best efforts to provide access to other necessary individualsCooperate in good faith in pursuing a publishing dealPay special attention to the indemnity. An indemnity is a promise to reimburse the other party should they breach their warranties. If the writer-for-hire relies on material provided by the hiring party, consider exclusing that material from the writer's representations and warranties.
Whether you are the author or a writer-for-hire, it's reassuring to be named as an additional insured on a publisher's media perils policy. While the big five publishers all have media perils policies, smaller publishers may not.
Protecting Confidential Information. Confidentiality clauses protect information exchanged between two individuals. Whether the information gained working on a book concerns family or business matters, a well-drafted confidentiality clause can deter someone from using that information against the discloser for personal gain. A well-drafted agreement might also include a non-disparagement clause. This is particularly important if you are a public figure or represent a public figure.
"You agree that you will not (nor will you cause or cooperate with others to) publicly criticize, ridicule, disparage or defame Subject, his family, his business associates, company, directors, officers, shareholders, employees, agents, or attorneys, with or through any written or oral statement or image, whether or not they are made anonymously or through the use of a pseudonym."
Case Study: Proceeding Without a Signed Contract — The Fay Vincent–David Kaplan Dispute
The dispute between Fay Vincent Jr., former commissioner of baseball, and writer David Kaplan illustrates the risks of moving forward without a signed collaboration agreement. The two planned a tell-all memoir with a $300,000 advance from Little, Brown & Company, split 60/40. Vincent sat for interviews and made editorial suggestions, but later withdrew and terminated his publishing contract.
Kaplan sued, seeking control of the manuscript. The court, however, found their unsigned collaboration agreement unenforceable and declined to resolve the joint authorship question on summary judgment.
Lesson: Even a carefully drafted agreement has no force if it is never executed.
Conclusion
The time to finalize a collaboration agreement is before the creative process begins — while both parties are enthusiastic about the project and willing to cooperate. Although negotiating financial terms, copyright ownership, and procedures for handling disputes may feel uncomfortable, addressing these issues upfront helps avoid costly legal battles later.
A well-crafted collaboration agreement protects both parties’ interests and provides a clear roadmap for the partnership. Whether you are hiring a ghostwriter, co-authoring with another writer, or adapting someone’s life story, investing in proper legal documentation at the outset can save time, money, and relationships in the long run.
