Chain of title
The paper trail proving who owns a copyright. Gaps in it stall sales and clearances.
Chain of title is the paper trail proving that the person offering you a right actually has it. It starts at creation — who wrote it, who recorded it, on what terms — and runs through every assignment, licence, inheritance and corporate transfer since. Owning a copyright and being able to prove you own it are different problems, and the second one is what stops deals.
A complete chain typically needs the agreements that created the work in the first place (producer, session and work-for-hire paperwork, a signed split sheet), the agreements that moved it (assignments, publishing and recording deals, catalogue purchase agreements), and evidence tying the paperwork to the registrations that name the current owner at the collecting bodies. In the US, transfers of copyright ownership must be in writing and signed to be valid, and they can be recorded with the Copyright Office — recordation is optional but gives constructive notice and can settle priority between conflicting transfers.
The cost of a gap is rarely a lawsuit — it is delay and discount. A music supervisor with a deadline moves to a track that clears cleanly. An acquirer either carves the affected works out of the purchase, holds money back against the risk, or reprices. Chain of title is therefore worth maintaining as an ongoing record rather than assembled under time pressure during diligence, which is when it is usually attempted.
Two statutory points shape what the trail has to show. A work made for hire has no later transfer to trace at all: under section 101 the employer or commissioning party is treated as the author from the outset, provided the work falls within one of the listed categories and, for a commissioned work, the parties signed a written instrument saying so. Everything else is an assignment, and section 204 requires it to be in writing and signed by the owner conveying it. Recordation under section 205 then governs priority between conflicting transfers, and can allow a later transfer taken in good faith for value to prevail over an earlier one that was never recorded.
Common questions
Does a copyright transfer have to be in writing?
In the US, yes. A transfer of copyright ownership is not valid unless it is in writing and signed by the owner conveying it. Non-exclusive licences are the exception.
Should transfers be recorded with the Copyright Office?
It is optional but useful. Recordation gives constructive notice of the transfer and can determine priority if two conflicting transfers of the same right exist.
