Copyright Assignment Defects: The Drafting Errors That Survive Decades

A single defective assignment from 2017 can void substantial brand value in 2026. The same five defects appear in M&A diligence year after year.

Copyright assignments fail in predictable ways. Companies discover the failures years later — in M&A diligence, in litigation, in investor diligence — long after the cure has become difficult. Five drafting defects account for nearly all of the failures, and each is preventable at modest cost when caught early.

This post addresses the recurring assignment defects, the doctrinal reasons they fail, and the cure strategies that resolve them before they become deal-breakers.

The “Agree to Assign” Trap

The single most common copyright assignment defect is the use of future-tense language. “Contractor agrees to assign all right, title, and interest…” does not transfer copyright. It creates an obligation to assign, which requires a separate executed assignment to actually transfer ownership. If the contractor leaves and refuses to sign, the company is left with at most an implied license of uncertain scope.

The fix is present-tense language: “Contractor hereby assigns all right, title, and interest…” This is self-executing at the moment of creation, requiring no separate document.

This is settled doctrine. Yet “agree to assign” language remains common in employment offer letters, consulting agreements, and joint development contracts — often inserted by counsel who did not appreciate the distinction.

Signature Defects

Assignments require valid signatures from authorized parties. The recurring failures:

• Wrong signatory — The agreement is signed by someone without authority — a manager rather than a corporate officer, a regional vice president lacking sign-off authority, an individual signing for an entity not yet formed.
• Missing parties — Joint authors must each sign for the assignment to transfer all rights. A sole signature transfers only the signer’s undivided interest — the other joint authors retain their own.
• Foreign signature requirements — Many foreign jurisdictions require notarization, apostille, or specific local forms. A U.S.-style assignment without these formalities does not transfer foreign copyright in those jurisdictions.
• Improper corporate execution — Assignments by entities require execution consistent with the entity’s governing documents — board resolutions, member consents, or signature authority limits.

Recordation Failures

Assignments can be recorded with the U.S. Copyright Office. Recordation provides constructive notice to subsequent purchasers, defeats certain bona-fide-purchaser arguments, and supports specific remedies in enforcement.

Common recordation failures include not recording at all (leaving the chain of title visible only in private documents); recording incomplete instruments; failing to record assignments of foreign copyrights with foreign offices that require recordation; and recording with errors in registration numbers or party identification that survive into the public record.

Joint Authorship Without Agreement

When two or more authors collaborate on a work intending their contributions to merge into a unitary whole, they are joint authors. Each owns an undivided interest in the whole and can independently grant non-exclusive licenses, subject to a duty to account.

Joint authorship without a written agreement creates ongoing obligations and conflicts. One joint author can license the work to a competitor of the other; one can refuse consent to assignments the other wants to execute; ownership disputes can paralyze enforcement.

The fix is a joint authorship agreement — ideally before the collaboration begins, but executable retroactively. The agreement should address ownership shares, license rights, and consent requirements for material decisions.

Work-for-Hire Misapplication

The work-for-hire doctrine is misapplied with regularity. The two paths:

• Employee work in the scope of employment is automatically work-for-hire. The company owns from creation.
• Specially commissioned work from a contractor is work-for-hire only if the work falls within one of nine statutorily enumerated categories (contribution to a collective work, part of a motion picture or other audiovisual work, translation, supplementary work, compilation, instructional text, test, answer material for a test, or atlas) AND the parties expressly agree in writing, signed by both parties, that the work is made for hire.

Software, marketing materials, and most product copy are not in the nine enumerated categories. For contractors creating those materials, work-for-hire is not available; only a written assignment can transfer ownership. Companies that rely on work-for-hire language for these works retain only an implied license.

Cure Strategies

For companies that discover existing defects, three cure paths are available.

• Confirmatory assignments — Short-form documents in which the original author confirms the assignment of work previously delivered. The standard tool, typically requiring fresh nominal consideration (such as a small payment) because past performance generally does not constitute valid consideration for a new promise.
• Settlement structures — For substantial works where the contributor seeks meaningful consideration, a negotiated buyout. Documented as a settlement and assignment.
• Re-implementation — Where the contributor cannot be reached or refuses, replacing the work with a clean-room implementation. Expensive but certain.

Cure costs scale with how long the defect has existed and how cooperative the contributor is. Recently departed cooperative contributors are easy; long-departed adversarial contributors are expensive. Early action favors the company.

Practice Note: Copyright assignment defects compound silently and surface under transactional pressure. A focused audit of contractor and employee copyright paperwork — ideally 18 months before any anticipated transaction — produces clean records on routine cadence at a small fraction of closing-pace cure costs.
