Domain Names Are Critical Digital Assets
Domain names are among the most valuable and most overlooked digital assets a business owns. Disputes arise when ownership is challenged, transfers occur without authorization, domains are used in ways that conflict with trademarks, or a domain's value becomes a central question in a transaction gone wrong. Bill Hartzer spent many years working directly within the domain name industry — including registrar operations and registry-level work — before building his consulting practice, and he provides expert witness services in domain-related litigation, UDRP arbitration, and related regulatory matters.
That industry background matters in these cases. Domain disputes are governed by a specific set of technical protocols (DNS, WHOIS/RDAP) and by a specific set of institutional rules (ICANN policy, registrar and registry agreements, the UDRP) that few expert witnesses have actually worked inside of. Bill has.
Domain Dispute Topics
Domain disputes tend to surface at the worst possible time for a business — often when a domain has already gone dark, email has already stopped working, or a deal is already close to closing. Because of that, these matters frequently move quickly and require an expert who can turn around a technical analysis fast enough to matter, while still producing findings that will hold up months later at deposition or trial.
Domain Theft & Unauthorized Transfers
Reconstructing how and when a domain left its rightful owner's control.
Registrar & Registry Practices
Whether a registrar or registry followed its own policies and its ICANN obligations.
UDRP & Cybersquatting
Expert support for Uniform Domain-Name Dispute-Resolution Policy complaints and responses.
Domain Valuation
Establishing fair market value for a domain name or portfolio in litigation or settlement.
DNS Configuration & Redirection
Unauthorized DNS changes that redirected traffic, email, or revenue away from its owner.
Evidence and Records Reviewed
Because domain records live across several distinct systems — the registrar, the registry, and DNS hosting, which are frequently operated by three different companies — a complete picture usually requires pulling records from each source rather than relying on any single one, since no single record-keeper has full visibility into everything that happened to a domain.
- WHOIS and RDAP records and historical ownership snapshots
- Registrar logs, transfer confirmations, and account event records where available
- DNS settings, hosting changes, and traffic redirection behavior
- Comparable domain sales and market valuation data
- Contracts, agreements, and policies governing domain use and transfer
Bill's expertise helps the court understand how domains are registered, secured, and transferred, and how established industry practice compares to what actually occurred in the case at hand.
