Joint copyright ownership when you collaborated without a written agreement

Short answer. Indian copyright law treats a work produced by two or more authors whose contributions have fused into a single work as a "work of joint authorship" under Section 2(z) of the Copyright Act, 1957. Section 17 decides who owns the resulting rights — the authors themselves in most collaborative settings, the employer for works made in the course of employment, the commissioning party for specific categories of commissioned work, and so on. When there is no written agreement, none of this disappears; it just becomes a fact-heavy fight about contribution, intent, and conduct. This article explains how the rules actually work and how disputes between collaborators are resolved in practice.

What counts as "joint authorship"

Section 2(z) of the Copyright Act, 1957 defines a work of joint authorship as "a work produced by the collaboration of two or more authors in which the contribution of one author is not distinct from the contribution of the other author or authors." Two things follow from the statutory language.

First, the test is the indistinguishability of the contributions, not the size of each contribution or the presence of a label. Two musicians who write lyrics and music together across a single session, where the final song reflects both inputs so thoroughly that they cannot be separated, have produced a work of joint authorship — even without a written record of the collaboration. Contributions that remain distinct (one person wrote the full lyric, another wrote the full music as a separate work and they were later combined) do not by themselves create joint authorship; the result is usually a composite work with separate copyrights in each component.

Second, the contribution must be to the work itself, not merely to the circumstances surrounding it. Providing the studio, suggesting a direction, funding the recording, or offering feedback does not make a person a joint author. The collaborator must have contributed original expression — original lyrics, original melody, original script language — that is embodied in the final work.

Ownership — Section 17 and its sub-rules

Section 17 of the Copyright Act is the first-ownership provision. As a default, the author is the first owner of the copyright. Section 17 then layers exceptions for specific categories. Section 17(a) addresses works made by authors under a contract of service or apprenticeship for newspapers and similar periodicals — in those cases, the proprietor of the periodical is the first owner in respect of publication in the periodical, subject to contrary agreement. Section 17(b) addresses works made by an author in the course of employment under a contract of service — the employer is the first owner unless otherwise agreed. Section 17(c) addresses photographs, paintings, and engravings made for valuable consideration at the instance of another — the commissioning party is the first owner, subject to agreement. Section 17(d) addresses government works and works by public undertakings.

The sub-rules matter because the same contribution can generate very different ownership outcomes depending on the relationship. A songwriter employed by a music company on a contract of service who writes a song in the course of employment is under Section 17(b) unless the contract says otherwise. An independent songwriter who co-writes with another independent songwriter outside any employment relationship is a joint author under Section 2(z) with joint ownership under the default author-first rule. A session musician whose contribution is arranged for specific valuable consideration and whose role is work-for-hire in substance is again different. The factual pattern decides which rule applies.

Why "tenancy in common" doesn't transplant cleanly

US co-authorship doctrine often borrows the real-property concept of "tenancy in common" — each joint author holds an undivided share and can exploit the work independently subject to an accounting to the others. Indian doctrine has not adopted this framing as such. The Copyright Act, 1957 defines joint authorship and then leaves the contours of exploitation to the principles of co-ownership of property read with the Act. In practice, Indian courts have taken the view that joint authors act together for exploitation; unilateral exploitation by one joint author without the consent of the others is not something the statute authorises and can attract injunctive and damages relief from the others.

The practical effect is that the instinct some collaborators carry from online sources — "I'll just release my version independently and account later" — is risky under Indian law. The safer path is either an agreement allocating exploitation rights by category (who can licence for sync, who for publishing, who for live performance) or a court-approved framework when the relationship has broken down beyond private settlement.

What evidence actually decides contribution

Where no written agreement exists, the question of who contributed what is decided on the contemporaneous record. Six categories of evidence carry weight.

Demos, drafts, and session files with timestamps. A DAW project file with layered contributions, a hand-written lyric sheet with edits in a particular person's handwriting, a script draft with tracked changes — these are strong evidence of contribution. Chats and email threads discussing the work at the creative stage. Casual messages negotiating specific lyric or scene changes, sending back-and-forth versions, or confirming a division of responsibilities often establish contribution more powerfully than later, interested testimony. Credits on the first release. The credit line on the first commercial release, particularly where registered with collecting societies, carries weight as an admission or acknowledgment. Payment and royalty records. How the collaborators have treated the work financially — who received advances, who was paid flat fees, who is registered with PRS or IPRS — signals the original understanding. Studio and production records. Session logs, engineer notes, and third-party production credits are useful corroboration. Public statements and interviews. Statements by either collaborator acknowledging contribution — in press, social media, or public performance introductions — are evidence of the original understanding.

The litigator's job in a contested collaborator case is to build a contribution narrative from these sources, not merely to have the client assert ownership at a high level. Courts tend to prefer a dispute presented with documentary scaffolding over one argued from personalities.

When the disputed work is a song or album

Music disputes are over-represented in collaborator litigation for structural reasons: bands form without paperwork, songs are written in sessions where nothing is timestamped, and the work only becomes valuable once it is released. When a dispute arises — a band-member departure, a streaming-revenue fight, a sync-licence opportunity with a brand — three questions recur. Who wrote the composition (music and lyrics)? Who owns the sound recording (typically the producer or label)? And who holds neighbouring rights (performer rights under the 2012 amendments to the Copyright Act)?

The three rights are legally distinct. Composition copyright is held by the author(s) of the song as a literary-musical work. Sound-recording copyright is held by the producer of the recording (usually the label or the party who funded the session), subject to contract. Performer rights are separate rights held by performers in relation to their performance. A collaborator dispute can pit the composer(s) against the label against the performers — and a settlement framework that allocates rights across all three categories is far more durable than one that only addresses "the song" as an undifferentiated asset.

Settlement frameworks that hold up

A workable settlement between collaborators, even after the relationship has broken down, typically has five elements. An allocation of shares in the work (percentage split of composition, sound recording, and performer rights separately where relevant). An allocation of exploitation rights by category — sync, publishing, live performance, merchandising, future derivative works — with default consent rules where categories are not specifically addressed. A collecting-society registration plan, ensuring the agreed split is reflected in IPRS, PPL, or ISRA registrations, so that real-world royalty flow follows the deal. A catalogue-freeze and mutual-release, ensuring that claims to the historical catalogue are resolved and each party releases the others in respect of past exploitation. A dispute resolution clause — arbitration or jurisdiction — for future disagreements.

A settlement that addresses shares without addressing collecting-society registration tends to break down again within a year. A settlement that allocates exploitation without a dispute mechanism becomes a set of further disputes waiting to happen. A workable settlement operates on the registration and exploitation plumbing, not just on the headline percentages.

When the other side is a production house or label

Where the dispute is between an individual collaborator and a production house or label, the legal question usually shifts. The issue is not Section 2(z) joint authorship but Section 17(b) (employment in course of service) or 17(c) (commissioned work) or the terms of an assignment deed. If a written assignment deed exists, its terms govern — and its terms may have consequences the individual creator never fully absorbed at the time of signing. If no assignment deed exists, the collaborator's position is typically stronger than the production house's, because Indian copyright does not lightly imply a full assignment from contribution to a commissioned project.

The practical advice, before litigation, is to obtain and review every document the collaborator has signed — engagement letters, release forms, commissioning paperwork, royalty statements, label forms — because the negotiating posture depends on whether the production house has a paper assignment or is relying on an implied one.

Closing thought

The rule that is often given to creators — "always sign a split sheet" — is correct, but it is advice for the next project, not the current dispute. Where the current dispute is live, the work is to build the contribution narrative from what exists, decide whether the case runs as a Section 2(z) joint-authorship matter or a Section 17 employment or commissioning matter, and craft either a settlement framework that addresses the collecting-society plumbing or a litigation strategy that stands on documented contribution rather than assertion.
