Chain of Title in Music: How to Verify Who Owns What Before Any Money Changes Hands

By Hank FasthoffJuly 6, 2026

Every license, every acquisition, every sync placement, and every royalty payment depends on one foundational question: who owns the rights? If the answer is wrong, incomplete, or undocumented, the deal can collapse, the royalties can freeze, and the parties can spend more on litigation than the catalog is worth.

Chain of title is the documented, unbroken sequence of ownership from the moment a song or recording is created to the current holder of each right. It's the music industry's equivalent of a real property title search. Before you buy a catalog, license a song, sign a publishing deal, or enter a sync agreement, confirming chain of title is the first step, not the last. A broken chain means the person selling, licensing, or collecting may not have the authority to do any of it.

What a Chain of Title Establishes

A single song involves multiple copyrights, and each one has its own chain of title.

Composition copyrights (the underlying song, including melody, lyrics, and musical structure) originate with the songwriter or songwriters who created the work. If multiple writers contributed, the composition is a joint work under 17 U.S.C. § 201, and each co-author owns an equal undivided interest unless they've agreed otherwise in writing. From the songwriter, ownership may transfer through publishing agreements (assigning part or all of the publisher's share to a music publisher), co-publishing agreements (splitting ownership between the songwriter's publishing entity and the publisher), administration agreements (the songwriter retains ownership but licenses administration rights to an administrator), and subsequent assignments, acquisitions, or estate transfers.

Master recording copyrights (the specific recorded performance) originate with the artist or producer who created the recording, unless a work-for-hire agreement or assignment transferred ownership to a label or another party. From the original owner, the master may transfer through recording agreements (the label acquires ownership in exchange for funding and distribution), producer agreements (the producer assigns master rights in exchange for points and credit), distribution agreements (the artist retains ownership but grants distribution rights), and subsequent catalog sales or corporate acquisitions.

Following each copyright from creation through every transfer to the current holder is what chain-of-title analysis does. If any link in the chain is missing, unsigned, or ambiguous, the current holder's claim to the rights is uncertain.

Where to Search

Chain-of-title research draws from multiple sources, because no single database contains a complete record of music copyright ownership.

U.S. Copyright Office records (searchable through the Copyright Public Records System at copyright.gov) include registration records (identifying the original author and claimant at the time of registration), recorded assignments and transfers (documenting subsequent changes in ownership), and recorded termination notices under § 203 and § 304 (identifying grants that have been or will be terminated by the author or the author's heirs).

PRO registrations (BMI, ASCAP, SESAC) identify the writers and publishers affiliated with each composition, along with the percentage splits registered by each party. PRO data reflects what the parties reported, not necessarily what the underlying contracts provide. Discrepancies between PRO registrations and the actual contractual splits are common, and PRO data alone isn't sufficient to confirm ownership.

Mechanical Licensing Collective (MLC) records include ownership and share data for compositions registered under the Music Modernization Act's blanket license. The MLC is currently holding over $400 million in unclaimed mechanical royalties from streaming, much of it attributable to compositions with incomplete or inaccurate ownership data.

Underlying contracts are the most authoritative source. Publishing agreements, recording agreements, producer agreements, co-writer split sheets, assignment documents, and estate documentation all establish or transfer rights. PRO registrations and Copyright Office records should reflect the underlying contracts, but when they don't, the contracts control.

Common Chain-of-Title Problems

Unregistered or undocumented co-writers. Modern popular music averages multiple songwriters per composition, and research shows the mean number of songwriters and publishers per song has tripled between 1958 and 2021. A co-writer who contributed a melody, a hook, or a verse but never signed a split sheet is an undocumented co-owner of the composition. Under the default rules of joint authorship (17 U.S.C. § 101), each co-author owns an equal undivided interest. An undocumented co-writer can surface after the song generates revenue and claim an ownership share that the other writers didn't account for. Without a signed split sheet documenting the agreed percentages, the default is equal ownership regardless of the relative contribution.

Missing producer assignments. A producer who created an original instrumental track owns the copyright in that recording and may also own a share of the composition copyright if the track includes original melodic or harmonic elements. If the producer never signed a work-for-hire agreement or a written assignment, the producer retains ownership of their contribution. A master recording that includes an unassigned producer contribution has a co-ownership problem that can prevent licensing, distribution, and sale.

Uncleared samples. A song that incorporates a portion of a pre-existing recording (a sample) requires two clearances: a license from the composition copyright owner (granting the right to use the sampled melody, lyrics, or musical elements) and a license from the master copyright owner (granting the right to use the sampled recording). An uncleared sample is a ticking infringement claim. If the sample was incorporated but never formally licensed, any subsequent license, sale, or sync placement of the song carries the risk that the sampled rights holders will assert their rights and demand compensation, an injunction, or both.

Inherited catalogs without proper estate documentation. When a songwriter or rights holder dies, the copyrights pass through the estate. If the estate documentation doesn't specifically address the music copyrights (a will that doesn't mention the catalog, an estate administration that doesn't inventory the copyrights, or multiple heirs who haven't agreed on how to manage the catalog), the chain of title becomes unclear. Licensing, collecting royalties, and selling the catalog all require a confirmed owner with the authority to act, and an estate that hasn't been properly administered can't provide that confirmation.

Termination and reversion rights. Under 17 U.S.C. § 203, authors who granted rights on or after January 1, 1978, can terminate those grants during a five-year window beginning 35 years after the grant (or 40 years after execution if the grant covers the right of publication, whichever ends earlier). Termination rights can't be waived by contract. A catalog that includes compositions approaching the 35-year mark may have grants that are subject to termination, which means the current publisher's ownership could be recaptured by the songwriter or the songwriter's heirs. Contractual reversion clauses carry similar risks if the publisher failed to meet performance benchmarks or if the reversion date has arrived.

Conflicting PRO registrations. When co-writers register the same composition with different PROs and report inconsistent ownership percentages (Writer A registers 60 percent with ASCAP while Writer B registers 50 percent with BMI, producing a claimed total of 110 percent), the PROs can't reconcile the data. Royalty payments freeze for all parties until the conflict is resolved, which can take months. Conflicting registrations are one of the most common and most frustrating chain-of-title problems, and they're preventable with accurate split sheets signed before the song is released.

Due Diligence for Catalog Acquisitions

Acquiring a music catalog (a collection of compositions, masters, or both) requires chain-of-title due diligence that goes beyond financial analysis. Legal due diligence for a catalog acquisition should confirm ownership of every composition and every master included in the transaction by reviewing the underlying contracts (publishing agreements, recording agreements, producer agreements, co-writer split sheets), cross-referencing them against Copyright Office registration records and PRO registration data, and identifying any discrepancies.

Verify that all sample clearances are documented and current. For every song that incorporates a sample, confirm that both the composition license and the master license were obtained, that the licenses are in writing, and that the licensed use covers the way the sample is used in the song.

Review every publishing, recording, and distribution agreement for reversion rights, termination rights, and option periods. A catalog that's valued at $2 million based on current income projections is worth significantly less if 30 percent of the compositions are subject to reversion within five years.

Confirm that PRO registrations match the contractual splits and that there are no unresolved registration conflicts. A composition with frozen royalties due to a PRO conflict is generating income that nobody can collect, and resolving the conflict may require the cooperation of co-writers who have no interest in helping.

Review estate documentation for any compositions or masters acquired from deceased rights holders. Confirm that the estate was properly administered, that the copyrights were specifically identified and transferred, and that all heirs with a potential claim have been accounted for.

Practical Recommendations

Use signed split sheets for every co-written composition, executed before the song is released. Every co-writer's legal name, PRO affiliation, publishing entity, and ownership percentage should be documented in writing with signatures from all parties. A split sheet prevents co-ownership disputes, ensures accurate PRO registration, and establishes the first link in the chain of title.

Require written assignments or work-for-hire agreements from every producer and contributor before the recording is distributed. An unassigned producer contribution creates a co-ownership interest in the master that can't be resolved after the fact without the producer's cooperation.

Register every composition and every master with the Copyright Office. Registration creates a public record of ownership, establishes a date of creation, and is a prerequisite to filing a federal infringement lawsuit.

Before licensing, acquiring, or selling any catalog or individual composition, conduct a chain-of-title review that follows each copyright from creation to the current holder through every documented transfer. Verify against Copyright Office records, PRO registrations, MLC data, and the underlying contracts. Any break in the chain should be resolved before the transaction closes.

Consult an entertainment attorney before exercising or responding to a termination notice under § 203 or § 304. Termination rights are subject to strict procedural requirements (written notice to the grantee not less than 2 nor more than 10 years before the intended termination date, filing with the Copyright Office before the termination date), and errors in the process can forfeit the right entirely.
