Acceptance of these terms
BillHartzer.net is published by Bill Hartzer. By accessing this website you agree to these terms of use. If you do not agree with them, the appropriate response is to stop using the site, which costs you nothing, since the site sells nothing and holds no account of yours.
These terms apply to this website alone. Hartzer Consulting at hartzer.com, DNAccess at dnaccess.com and BillHartzer.com are separate properties with their own terms, and any commercial relationship arising from one of those sites is governed by the agreement entered into there, not by this page.
What this site is
This site is a biographical and informational record: professional history, speaking engagements, publications and media citations, and descriptions of the practice areas in which Bill Hartzer works. It exists so that the public record about him is accurate, sourced, and written by him.
It is not a marketing site. It does not publish rates, take a brief, accept an engagement, or generate a quote. Every reference to commercial work points to Hartzer Consulting or DNAccess, where that work is actually performed under a written agreement. Nothing on this site is an offer to perform services, and nothing you send in response to it creates an obligation on either side.
No legal advice and no professional relationship
Nothing on this website is legal advice. Bill Hartzer is not an attorney and does not practice law. The material here about litigation support, expert witness work, evidence, discovery, trademark disputes, cybersquatting or domain name proceedings describes a technical practice as it interacts with legal processes. It is not advice about your matter and must not be relied on as a substitute for advice from a licensed attorney in your jurisdiction.
Reading this site, downloading anything from it, quoting it, or sending an email in response to it does not create an attorney-client relationship, a consulting relationship, an expert engagement, a fiduciary duty, or a duty of confidentiality. No such relationship exists until it has been agreed in writing, through the proper channel, with the necessary checks completed.
This matters in a specific and practical way. Unsolicited information sent to a prospective expert may not be treated as confidential and may, depending on circumstances, create a conflict that disqualifies that expert from a matter. Do not send case facts, documents, party names, or privileged material through this site or in a first email. Establish the engagement first.
How expert witness engagements are actually entered into
Expert witness engagements are entered into only through counsel, and only through Hartzer Consulting. They are not accepted through this website, are not accepted directly from a party to a dispute, and are not created by correspondence.
The ordinary sequence is a conflicts check, then a discussion of scope, posture and timing, then a written engagement agreement covering the work to be performed and its terms. Only after that agreement is in place is there any expert relationship, any obligation to review materials, or any protection attaching to what is exchanged. Anything sent before that point is sent at the sender's own risk and should be limited to what a stranger could safely read.
Nothing on this site should be read as a representation that Bill Hartzer is available for, qualified for, or willing to accept any particular matter. Availability, conflicts and subject-matter fit are assessed case by case, and declining an engagement is a routine outcome.
Accuracy, sourcing and changes to content
The content here is prepared carefully and sourced deliberately. Where a fact rests only on Bill Hartzer's own records rather than on independent confirmation, this site says so in the text rather than presenting the two tiers as equivalent. Where a claim could not be substantiated, it is left out.
Even so, this site is provided without any warranty that it is complete, current or error-free. Search engines, registrar practice, domain name policy and the technical particulars of the web all change, sometimes quickly. An article accurate on the day it was written may describe behavior that no longer occurs. Content may be edited, corrected, restructured or removed at any time without notice, and no obligation is assumed to update any page.
Copyright and permitted use
The text, structure and original material on this site are the copyrighted work of Bill Hartzer, except where third-party names, marks or quoted material appear. All rights are reserved.
You may read the site, print or save pages for your own reference, and quote short excerpts with attribution and a link back to the page quoted. That is normal citation and it is welcome; a biographical record that could not be quoted would be pointless.
You may not republish substantial portions of the site elsewhere, present its content as your own, sell or license it, use it to train a commercial model without permission, or scrape it systematically in a manner that burdens the server or reproduces the site in bulk. Reproducing the professional record in a way that suggests Bill Hartzer authored, reviewed or endorsed your version of it is not permitted, and neither is altering quoted text in a way that changes its meaning.
Third-party names, trademarks and links
Company names, product names, conference names, publication names and trademarks referred to on this site belong to their respective owners and are used for identification, citation and descriptive purposes only. Their use here does not imply affiliation, sponsorship or endorsement in either direction, except where a relationship is expressly stated, as with the brand ambassador roles that are disclosed in the biography.
This site links to third-party websites, including publisher archives, conference organizers and trade publications cited as sources. Those sites are not under my control. No responsibility is accepted for their content, accuracy, availability, security or practices, and a link is a citation rather than an endorsement. Following a link takes you outside these terms and under someone else's.
No warranty and limitation of liability
This site is provided on an as-is and as-available basis. To the fullest extent permitted by law, all warranties are disclaimed, express or implied, including warranties of accuracy, merchantability, fitness for a particular purpose and non-infringement. No warranty is given that the site will be uninterrupted, error-free, secure, or free of harmful components.
To the fullest extent permitted by law, neither Bill Hartzer nor Hartzer Consulting is liable for any direct, indirect, incidental, consequential, special or exemplary damages arising out of or in connection with your use of this site or your reliance on anything published on it, including lost profits, lost rankings, lost revenue, lost data, or the outcome of any dispute or transaction. If you take action based on general information published here without obtaining advice specific to your circumstances, that decision and its consequences are yours.
Governing law and contact
These terms are governed by the laws of the State of Texas, where I am based, without regard to its conflict of law provisions. If any provision of these terms is held unenforceable, the remaining provisions continue in full effect, and the unenforceable provision is to be applied to the maximum extent permitted.
These terms may be updated from time to time, and the version published here is the version that applies. Continued use of the site after a change constitutes acceptance of the updated terms. Questions about these terms can be sent using the contact link on this site. Questions about a commercial engagement belong with Hartzer Consulting instead. Last reviewed August 2026.
