Music Catalog Due Diligence Before Buying Royalty Rights

A catalog can show strong historical collections while carrying gaps in title, expiring rights, or missing registrations that reduce what the buyer actually owns. Music catalog due diligence turns a projected royalty stream into a defined legal asset with a measurable risk profile.

For investors, publishers, and acquisition teams, the work must go beyond reviewing seller statements. It requires a work-by-work review of ownership, contracts, collection data, statutory reversion exposure, and the deal terms that allocate unresolved risk.

Start with the asset, not the revenue multiple

A purchase price often begins with a multiple of net publisher’s share or master income. That multiple has little meaning until the buyer knows which rights are included, in which territories, and for how long.

A catalog schedule should identify every composition and recording, the applicable ownership percentage, the seller’s chain of title, and every excluded interest. Broad descriptions such as “worldwide publishing rights” can hide territory limits, administration carve-outs, co-writer shares, and pending reversions.

Separate compositions from sound recordings

A musical composition protects the music and lyrics. A sound recording protects the recorded performance. They are separate copyrights, often with different owners, income streams, and contract histories.

For example, a buyer may acquire a publisher’s interest in a song without acquiring the artist’s master recording. A label may control a master while songwriters retain or later reclaim composition interests. The catalog schedule should track each right separately, rather than treating a song and its recording as one asset.

Identify what the seller can actually convey

The seller may own copyright, administer copyright, collect income, or hold a limited license. Those positions have different value.

Review whether the seller has authority to:

• Assign ownership interests and grant future licenses.
• Collect royalties from domestic and foreign administrators.
• Approve synchronization uses or settle infringement claims.
• Bind co-owners, writers, producers, heirs, and affiliated entities.

A royalty statement confirms that money was paid. It does not establish who owns the underlying copyright. That distinction should guide the entire diligence process.

Build a chain of title that holds up under pressure

Every high-value work needs a document trail that reaches from the original creator to the seller. Missing links often arise after mergers, dissolved entities, informal producer deals, and unsigned amendments.

Review the documents behind each ownership claim

Start with copyright registrations, writer and producer agreements, split sheets, publishing agreements, label deals, work-for-hire provisions, assignments, amendments, and prior acquisition documents. Then compare the documents with the seller’s schedule.

Under 17 U.S.C. section 201, ownership can transfer through a written instrument signed by the owner. A registration record can support the investigation, but it may not resolve a conflicting assignment or an unrecorded transfer. Where appropriate, recordation under section 205 can also affect priority disputes involving transfers.

Work-for-hire language deserves particular attention. Calling a recording a work made for hire does not always settle authorship or termination questions. The statutory requirements and relationship between the parties matter.

Search for liens, claims, and deal restrictions

A buyer should run UCC searches and review financing documents, security interests, collection account agreements, recoupment provisions, litigation files, and prior notices of dispute. A lender’s lien may attach to copyrights, receivables, or both.

Existing contracts can also restrict a sale. Check consent rights, rights of first refusal, reversion clauses, audit claims, approval rights, exclusivity commitments, and restrictions on sublicensing. Distribution agreements may contain broad grants or platform-control terms that remain in force after closing. Review music distribution agreement terms before assuming a distributor relationship is freely transferable.

Reconcile registrations with royalty systems

Title review is incomplete until the buyer compares the legal file with the databases that route money. Names, titles, percentages, and identifiers often vary across systems.

Match the same work across every database

Create a reconciliation table for each material work. It should compare copyright registration data, publisher records, PRO registrations, Mechanical Licensing Collective data, distributor reports, administrator schedules, ISWC and ISRC data, and the seller’s accounting records.

Differences in songwriter spelling, ownership splits, alternate titles, or recording identifiers can cause delayed payments or competing claims. A catalog team should investigate discrepancies before closing, then assign a cure plan and financial reserve to unresolved items.

Review area	Evidence to compare	Common issue
Composition ownership	Split sheets, registrations, publishing agreements	Unapproved writer share
Master ownership	Artist, producer, and label agreements	Producer royalty or approval claim
Digital mechanicals	MLC work claims and statements	Missing share or unmatched work
Performance income	PRO registrations and statements	Conflicting publisher affiliation
International income	Subpublishing and society statements	Territory or term mismatch

The goal is a single source of truth that explains why each royalty payment reaches the catalog.

Test accounting rights before relying on statements

Request at least three years of detailed statements, not only summary reports. Examine payment timing, deductions, reserves, foreign exchange treatment, prior-period adjustments, unidentified receipts, and unclaimed balances.

Audit clauses matter because they set the objection deadline, scope of inspection, cost shifting, and access to underlying records. A buyer needs to know whether historical underpayments can be pursued after closing. The practical issues in reviewing a music royalty statement often reveal whether an accounting claim is still viable.

Unmatched royalties are not automatically lost royalties. They may reflect incomplete claimant data, which still requires correction before a buyer counts the income as reliable.

Review contracts that shape future income

Catalog rights carry the obligations attached to them. Diligence should identify what survives the sale and what can change the buyer’s future control over licensing and collections.

Find administration, co-publishing, and subpublishing limits

A co-publishing deal may give the seller only part of the publisher’s share. An administration agreement may give another company collection authority for a fixed term. A subpublisher may control foreign licensing in designated territories.

Review commission rates, renewal rights, termination provisions, audit clauses, minimum guarantees, recoupment rules, reserved rights, and post-term collection periods. If a seller has granted a long post-term collection right, a buyer may own the copyright while waiting years to receive income directly.

For composition rights, direct music licensing guidance helps distinguish privately negotiated licenses from rights administered under the statutory mechanical framework.

Examine synchronization and approval obligations

Synchronization income can produce meaningful one-time payments, but existing deals may restrict future uses. Identify any artist approval rights, moral-rights concerns, category exclusions, political-use restrictions, most-favored-nations obligations, and prior blanket licenses.

A sync clearance generally requires both the composition right and the master-use right when a production uses a released recording. Review composition and master use licenses with the catalog’s actual contracts in mind. A buyer who owns only one side cannot promise full clearance.

Evaluate statutory termination risk under U.S. law

Termination rights can end earlier grants and return certain U.S. copyright interests to authors or statutory heirs. They do not erase the copyright itself, and they cannot be waived in advance through broad contract language.

Apply Section 203 to post-1977 grants

Section 203 generally covers grants executed on or after January 1, 1978. The statutory window typically opens 35 years after execution, or 40 years after publication when the grant covers a right of publication.

The window lasts five years. Notice must comply with strict timing, service, signature, and recordation requirements. Each important work should be classified as having no known exposure, possible future exposure, notice served, pending effective date, or completed reversion.

The U.S. Copyright Office maintains termination-related materials, but a catalog buyer should analyze the signed grant, amendments, publication facts, and author history rather than rely on a generalized date calculation.

Address older works and derivative works separately

Sections 304(c) and 304(d) may create termination exposure for certain grants involving pre-1978 copyrights. These older works need their own schedule because the applicable statute and dates may differ from Section 203.

The Supreme Court’s decision in Mills Music, Inc. v. Snyder, 469 U.S. 153 (1985), addressed the derivative-works exception in the older termination framework. Lawfully prepared derivative works may continue after termination under the statute. That does not give the prior grantee unlimited authority to authorize new uses after reversion.

A remaster, compilation, or existing audiovisual use may therefore require separate treatment from future synchronization licenses. Foreign rights also require a territory-by-territory review, since U.S. termination law does not automatically determine ownership abroad.

Confirm how mechanical and performance royalties are collected

Royalty collection depends on accurate ownership data and on the correct administrator receiving instructions after closing. This operational review should run alongside the legal review.

Verify MLC claims and digital mechanical data

The Mechanical Licensing Collective administers the U.S. blanket mechanical license for eligible digital audio uses of musical works. It matches digital service provider usage data to registered works and distributes the resulting royalties.

Request MLC work summaries and royalty-detail files. Test the songwriter and publisher shares, title variants, service data, adjustments, and matched recordings. Registrations should align with the catalog schedule and the buyer’s post-closing collection plan.

The MLC does not collect every revenue stream. Performance income, neighboring rights, synchronization fees, physical royalties, and many foreign collections may follow different routes. Use music rights licensing and royalty management to map which administrator handles each right.

Separate PRO and SoundExchange revenue

ASCAP, BMI, SESAC, and GMR administer public-performance income under their respective systems. Verify writer and publisher affiliations, cue-sheet records, direct-license exclusions, and any advances or distribution holds.

SoundExchange handles a separate U.S. statutory stream for qualifying noninteractive digital performances of sound recordings. It does not replace on-demand streaming income from services such as Spotify or Apple Music. Master owners, featured artists, and nonfeatured performers can have distinct claims, so the diligence request should not collapse them into one master-revenue line.

Stress-test the revenue model and rate exposure

Historical collections provide a starting point. Buyers still need to understand the legal, contractual, and market facts behind the numbers.

Treat statutory rates as inputs, not fixed assumptions

The Copyright Royalty Board sets certain statutory rates. Its current web docket materials include the 2026 through 2030 rate period, and the March 2026 rule discussed by the Copyright Royalty Board’s termination update shows why statutory systems require active monitoring.

Do not apply a single rate to all streaming revenue. Contract type, service configuration, statutory formula, territory, and ownership share affect the amount that reaches the catalog. Model downside cases for rate changes, higher administrator fees, loss of a major repertoire share, and late data corrections.

Test concentration and nonrecurring income

Identify the top 10 works, top writers, top licensees, and top territories. A catalog dependent on a small group of songs can suffer a sharp valuation change if one share reverts, a platform removes content, or a major sync relationship ends.

Separate recurring income from exceptional receipts. A large settlement, audit recovery, viral spike, or one-time synchronization license should not automatically support a recurring revenue forecast. Also distinguish accrued income earned before closing from income generated after closing.

Put unresolved risks into the purchase agreement

The purchase agreement should convert diligence findings into precise obligations and remedies. Generic representations that the seller owns “all rights” often fail to address the records that matter most.

Use targeted representations and indemnities

Representations should address title, authority, ownership percentages, liens, registrations, prior grants, claims, notices of termination, royalty statements, audit disputes, and material contracts. Schedules should disclose exceptions work by work.

For known uncertainty, consider a purchase-price exclusion, escrow, special indemnity, holdback, or contingent payment. A near-term termination risk may justify excluding the affected U.S. share or tying part of the price to collections that remain payable after the effective date.

Define post-closing mechanics before signing

The agreement should state who receives pre-closing income paid after closing, who pursues old audit claims, and who bears the cost of correcting registrations. It should also require the seller to deliver files, execute transfer documents, issue letters of direction, and cooperate with collection societies.

Chase Lawyers can help buyers and sellers structure these protections through IP rights licensing and royalty management, including royalty audits, licensing review, contract enforcement, and dispute-resolution planning.

• Seller statements should be reconciled against registrations, administrator data, agreements, and detailed royalty reports.
• Sections 203, 304(c), and 304(d) can reduce the duration of acquired U.S. rights, even where an old agreement claims to be perpetual.
• Known risks should affect the price and appear in targeted indemnities, escrows, exclusions, or contingent payments.
• Chase Lawyers can assess title, royalty administration, statutory reversion risk, and closing mechanics before capital is committed.

Frequently Asked Questions

Does buying a catalog include both publishing and master rights?

Only if the purchase agreement says so and the seller owns both interests. Publishing rights concern the composition, while master rights concern the recording. A buyer should require separate schedules and chain-of-title evidence for each asset class.

Can an old “perpetual” publishing agreement block termination?

No contract label alone eliminates a valid statutory termination right. The applicable analysis depends on the grant date, copyright history, authorship, statutory heirs, notice requirements, and potential exceptions such as a valid work-made-for-hire arrangement.

Are MLC payments the full measure of streaming value?

No. MLC distributions concern eligible U.S. digital mechanical royalties for musical works. A complete analysis may also include performance royalties, master income, direct licenses, foreign collections, and other revenue that does not flow through the MLC.

Final Thoughts

A catalog purchase becomes more defensible when the buyer can trace each material right from creator to seller, reconcile it to real collections, and account for its remaining legal life. Clean title and reliable data deserve the same attention as the revenue multiple.

Chase Lawyers helps music-rights investors, publishers, and creators assess those issues before closing, so the final agreement matches the rights and income the transaction is meant to deliver.
