Music Copyright Expert Witness
Whether you are pressing a claim or answering one, the figure in the letter is a claim, not a valuation. We produce independent, court-ready evidence of what a licence for that use would actually have cost. We are instructed by both sides.
What is the music actually worth, and who says so?
There is no published rate card for sync licensing and benchmarks vary widely depending on who you ask. The question a tribunal actually asks is narrower: what would a willing licensor and a willing licensee have agreed for this track, this use, this territory and this term?
Bringing a claim. Your client’s music was used without a licence and the figure on the table is a fraction of what the use was worth. We establish the fee which would have been payable, supported by comparables a tribunal can inspect, so the number you put forward survives challenge rather than inviting one.
Defending a claim. A letter of claim has landed and it names a figure for music used in an advert, a social post or a video. Claim letters are commonly built from a rights holder’s own rate card, a statutory multiplier or a settlement anchor. None of those is evidence of market value, and the claimed figure is often well above what a licence would actually have cost.
Either way you need an independent expert who can produce a valuation that holds up under cross-examination: not a guess, not a rule of thumb, but a structured, evidence-based analysis backed by verifiable comparables and a stated methodology.
What is sync licence quantum?
Quantum is the size of the claim: the fee which would have been payable had the use been licensed properly. In sync it is driven by the artist’s standing, the media and territory, the term and any exclusivity, how prominent the music is in the edit, and the commercial weight of the campaign behind it.
Two uses of the same recording can differ by an order of magnitude on those factors alone. A three-second bed under a regional social post and a hero sync in a global television campaign are not the same licence, and a quantum figure that does not distinguish them will not survive cross-examination.
Why not instruct a forensic accountant?
Because sync quantum is not in the books. A forensic accountant is the right expert for tracing revenue, profit and loss through a set of accounts. The licence fee which would have been payable sits somewhere else entirely: in comparable deals, at comparable prominence, in comparable markets, at the relevant point in time.
Different question. An accountant reconstructs what a business earned. We establish what a licence would have cost.
Different evidence base. Ledgers and management accounts, against sync deal comparables drawn from active market practice.
Different cross-examination. The pressure lands on whether the comparables are apt, which is a sync practitioner’s question rather than an accounting one.
In practice the two are complementary. Where an account of profits is in play, a forensic accountant and a sync valuation answer different halves of the same claim, and we are used to working alongside one.
What does a sync licensing expert witness do?
A sync licensing expert witness produces a court-ready valuation report, delivers written and courtroom testimony, rebuts opposing analysis, and supports pre-litigation settlement. Those are the four things a case actually needs.
Will the valuation hold up in court?
Yes: the xSV™ framework has been accepted and upheld in every jurisdiction it has been presented in, including US federal courts, German civil proceedings (Landgericht and Oberlandesgericht), UK courts, and across the EU.
A clear, well-structured valuation changes the dynamics of a negotiation. When both sides understand the defensible value, disputes resolve faster.
Why instruct a sync specialist rather than a general music expert?
Specialization. We focus exclusively on sync licensing valuation. Other music experts cover royalties, publishing, and general IP. We go deeper in the specific domain that matters for your case.
Methodology. The xSV™ framework is structured, repeatable, and transparent. It produces consistent results that can be explained clearly in court rather than black-box estimates.
Speed. Standard reports in 5–10 business days. Expedited delivery available for urgent litigation timelines.
Fixed pricing. We quote a fixed fee upfront based on case complexity. No hourly billing surprises.
