For Texas Lawyers
For Texas Lawyers: Co-Counsel and Referral Information
If you're a Texas lawyer and an oilfield case has landed on your desk, you already know it isn't a standard injury file. Chapter 95 is waiting. There's a Master Service Agreement you haven't seen yet. There are five companies on the site and only one of them is easy to find. This page is about what to do with that.
Some lawyers want to refer the case out and be done with it. Others want to keep their hand in, stay close to the client, and bring in a trial partner who lives in this area of the law. Both work. This page explains how the association works, what the team brings, and how the fee is divided under the rules, so you can decide which fits you and your client.
Guy Muller handles oilfield injury and wrongful-death cases in association with The Stewart Law Firm, PLLC, of Austin. The arrangement follows Texas Disciplinary Rule of Professional Conduct 1.04, in writing, with the client's informed consent. The first conversation is confidential and costs nothing.
The short version
- This page is for Texas lawyers who have an oilfield injury or death case and want experienced co-counsel. You can refer it out, or stay involved as co-counsel.
- Guy Muller handles these cases in association with The Stewart Law Firm, PLLC, of Austin. Stephen W. Stewart has handled catastrophic injury, wrongful-death, and defective-product cases, including oilfield work, since 1997.
- Either way, the arrangement goes in writing, and the client gives written, informed consent before the referral or association happens.
- Fee division between lawyers in different firms is governed by Rule 1.04(f). Texas courts generally treat a split that doesn't satisfy it as unenforceable on public-policy grounds, though some opinions discuss narrow equitable arguments on particular facts. Get the client's written consent up front, and don't rely on an after-the-fact workaround.
- Oilfield cases turn on Chapter 95, the Master Service Agreement, and the chain of companies on the site. They reward a team that knows that ground before the defense starts moving.

Who this page is for
You don't have to handle oilfield cases for a living to end up holding one. A roughneck's wife is your client's cousin. A wrongful-death call comes in and the family lives two counties over. You took the case because they trusted you, and now you're staring at a file that fights back harder than anything on your desk.
These cases are expensive to work and built to be defended. The operator and its contractors carry insurance with lawyers already on retainer, and those lawyers go to work fast, often before the worker is out of the hospital. The evidence that decides the case (the daily drilling reports, the JSA, the equipment, the Master Service Agreement) sits in the hands of the companies you'll be suing. Experts cost real money up front, and you may need several. A solo or small firm can absolutely win one of these. But it's hard to do it alone, and it's harder to do it part-time.
That's the gap this page is about. If you've got a strong oilfield case and you'd rather have a trial partner than carry the whole load yourself, there's a straightforward way to do it.
The co-counsel model and the Stewart Law Firm association
When two lawyers from different firms work the same case for the same client, Texas calls that an association, and the lawyers are co-counsel. It's an everyday arrangement, and the rules that govern it are clear once you've seen them.
A referral is when you send the case to another lawyer and step back. An association (co-counsel) is when you and another lawyer both stay on the case for the same client at the same time. Under Texas Disciplinary Rule 1.04, the fee can be divided in either situation, but only if the client agrees in writing first and the other requirements are met. The old "forwarding fee," where a lawyer sent a case along, did nothing else, and still took a cut, no longer works on its own. The current rule wants either a real division of work or shared responsibility for the representation.
Guy Muller handles oilfield cases in association with The Stewart Law Firm, PLLC, in Austin. The point of the association is depth. Oilfield injury and death cases reward lawyers who already know the statute, the contracts, and the way the companies on a site point at each other, and who have stood in front of a jury with that material before.
Guy Muller handles oilfield injury cases in association with The Stewart Law Firm, PLLC, of Austin, Texas, under an association agreement. Co-counsel arrangements are governed by Texas Disciplinary Rule of Professional Conduct 1.04(f) and are made with written client consent and full disclosure.
What the team brings to an oilfield case
Stephen W. Stewart founded The Stewart Law Firm in Austin and has been licensed in Texas since 1997. His practice is catastrophic personal injury, wrongful death, and defective products, and that work includes oilfield and industrial injury cases. Before he started representing injured people, he spent years on the other side, defending product-liability claims for large manufacturers. He has seen how the defense builds these cases, which is useful when you're the one taking them apart.
A note on my own background, since referring lawyers ask. Before I started my firm, I worked in-house as corporate counsel, first as Associate General Counsel for an AR/VR and SaaS technology company, then as General Counsel for a global publishing company. A large part of that job was drafting and negotiating service contracts, indemnity provisions, and insurance requirements. Different industries, same contractual architecture. When a Texas court reads a Master Service Agreement and asks whether one company "expressly" agreed to cover another's negligence, or whether the indemnity language was conspicuous enough to hold up, it's reading the kind of language I used to write. I'm not going to tell you I drafted oilfield contracts. I'll tell you I know how that machinery is built and where it tends to get sloppy when a real person gets hurt.
What that combination means for your file is simple. Somebody on the team has tried this kind of case, and somebody on the team can read the contract that often decides it. The substantive ground is covered in the public guide, including what Chapter 95 actually requires and the rest of the South Texas Oilfield Injury Guide.
The danger sits with the contractors, not the operators. So does the liability puzzle. In 2023, the U.S. recorded 113 fatal work injuries across the mining, quarrying, and oil and gas extraction sector. Only 10 of those deaths were classified under oil and gas extraction itself, the operator side. The larger share, 70 deaths, fell under support activities for mining, which is the drilling contractors and oilfield service companies that send workers to the wellsite. Within that group, transportation incidents alone accounted for 33 of the 70. The people getting killed are overwhelmingly contractor and service-company workers, and that's exactly why these cases turn on sorting out which company on the site did what.

It starts with a phone call. We run a conflicts check, you tell me what you have, and we look at it together. If it isn't a fit, I'll say so and tell you why. If it is, we put the arrangement in writing and get the client's written consent before anything moves, which is what Rule 1.04 requires.
From there, you choose how involved you want to be.
You can refer the matter and stay informed without carrying the day-to-day. Or you can stay on as co-counsel and assume joint responsibility for the representation, which keeps you in the loop on the work and the decisions. Rule 1.04 builds that second path out in its comments: a lawyer who assumes joint responsibility is expected to make reasonable efforts to see that the representation is adequate, to refer the matter to a lawyer competent to handle it, to stay reasonably informed as the case moves, and to make sure the client's questions get answered. You don't have to attend every deposition or sit in on every hearing to meet that standard, but you do have to stay genuinely connected to the case.
The team carries the financial weight that makes these cases possible: the case expenses, the experts, the cost of prying evidence out of the companies that are holding it. Your client keeps you as the lawyer they already trust, and gains a trial firm that has done this work.
If you want a sense of the substance before you call, two attorney references on this site show the kind of material these cases run on: the Texas Oilfield Discovery Reference, a topic list of what to ask for and where the evidence hides, and the Texas Oilfield Case Law Tracker, which follows the decisions that move this area.
Have a case you're weighing? Call or text (210) 460-0569, or email guy@guymullerlaw.com. We'll talk it through, lawyer to lawyer. If it makes sense to work it together, we'll put the association and the client's written consent in place under Rule 1.04(f). If it doesn't, I'll tell you that too.
Call or text (210) 460-0569Fee division under Rule 1.04
This is the part referring lawyers want pinned down, so here it is in plain terms.
Texas Disciplinary Rule of Professional Conduct 1.04(f) governs how lawyers who aren't in the same firm divide a fee. It allows the division only if three things are true. First, the split is either in proportion to the work each lawyer performs, or it's made between lawyers who assume joint responsibility for the representation. Second, the client consents in writing to the terms before the association or referral happens, and that written consent has to spell out who's participating, whether the division is by proportion of work or by joint responsibility, and the share each lawyer or firm will receive (or the basis for figuring it). Third, the total fee still has to be reasonable, not unconscionable, under Rule 1.04(a).
Three things have to line up before lawyers in different firms can divide a fee:
- The split is in proportion to the work each lawyer does, OR the lawyers assume joint responsibility for the case.
- The client consents in writing, before the referral or association, and that writing names the lawyers, says whether the split is by work or by joint responsibility, and states each lawyer's share or how it will be figured.
- The total fee is still reasonable under Rule 1.04(a). Get the written consent up front and the rest follows. Skip it, and you may not be able to enforce the split at all.
There's a companion provision worth knowing. Rule 1.04(g) says an agreement that lets one lawyer bring in or refer to a lawyer at a different firm has to be confirmed in the way (f) describes. A client's consent given without knowing the (f)(2) terms doesn't count as confirmation. And if the agreement isn't confirmed the right way, a lawyer can't collect the agreed fee, only the reasonable value of services actually provided and the reasonable expenses actually incurred. Texas also requires, by statute, that a contingent-fee contract be in writing and signed by the client and the attorney, under Section 82.065 of the Government Code. The takeaway for a referring lawyer is that the disclosure and the signatures aren't a formality you clean up later. They're the thing that makes the fee enforceable.
The team handles this paperwork as a matter of course. You won't be left to draft it.
A short, plain summary of how Texas courts treat fee-division agreements between lawyers in different firms. This is legal background, not a prediction about any case.
Johnson v. Brewer & Pritchard, P.C. (Tex. 2002) stated the core principle: a fee-sharing agreement between lawyers who aren't in the same firm violates public policy and is unenforceable unless the client is advised of and consents to the arrangement. The opinion applied an earlier version of the rule; in 2005 the rule was tightened to require that the consent be in writing and disclose the specific terms now found in 1.04(f)(2).
Cruse v. O'Quinn (Tex. App., Houston [14th Dist.] 2008, pet. denied) confirmed that a court may treat Rule 1.04 as an expression of public policy, so a fee-sharing contract that violates it can be unenforceable as against public policy. The specific facts involved a lawyer who could no longer carry joint responsibility after being suspended and disbarred.
Gillespie v. Hernden (Tex. App., San Antonio 2016) quoted the current 1.04(f) and confirmed that the Disciplinary Rules don't themselves create a private cause of action. The opinion also discussed a quasi-estoppel argument in a client-benefits setting, but later courts have treated that path narrowly, so it isn't safe to read Gillespie as a general license to enforce any fee split that lacks the writing Rule 1.04(f) requires. The safe reading is still the plain one: get the writing done up front, and don't count on an equitable workaround after the fact.
Padua v. Gibson (Tex. App., Houston [14th Dist.] 2023) is narrower than it first looks. The court treated client-signed consent as the public-policy line for whether the contract is enforceable, and held that even assuming the fee-sharing agreement was unenforceable for lack of that consent, the agreement's unenforceability didn't bar separate tort claims between the lawyers, because those claims turned on the parties' conduct rather than on enforcement of the contract itself.
You keep your relationship with your client and a share of the fee. The size of that share depends on how the work and responsibility are divided, which we agree on with you up front and put in writing. The one practical non-negotiable is the client's written, informed consent before anything moves. Texas courts generally treat a noncompliant fee split as unenforceable on public-policy grounds, and the narrow equitable discussions in some opinions aren't something a referring lawyer should plan around. The team prepares the documents that satisfy Rule 1.04. Your job is the part you already do well: be straight with your client and stay reachable.
How to start a conversation
Call or text (210) 460-0569, or email guy@guymullerlaw.com. A first call usually takes fifteen or twenty minutes. It helps to have the basics in front of you: who was hurt and how, who they worked for, which companies were on the site, and any deadline you're watching, since limitations and notice issues can move fast in these cases. You don't need a worked-up file. A clear picture is enough to tell whether it's worth a closer look.
The conversation is confidential, and your client's information is protected under Rule 1.05. Talking through a case doesn't commit you or your client to anything. If we go forward, we paper the association and get the client's written consent. If we don't, you've lost nothing but the time of a phone call, and you'll have a straight answer about what you're holding.

Call or text (210) 460-0569Common questions
How does the co-counsel arrangement work? +
We talk, run a conflicts check, and look at the case together. If it's a fit, we put the association in writing and get your client's written consent before anything moves. You then either refer the matter and stay informed, or stay on as co-counsel with joint responsibility. The fee is divided the way you and the client agree, under Rule 1.04(f).
Can I stay involved in the case? +
Yes, as involved as you want to be. If you assume joint responsibility under Rule 1.04, you stay connected to the work and the decisions and keep the client relationship you already have. Rule 1.04's comments describe what that involvement means: stay reasonably informed, help make sure the representation is adequate, and see that the client's questions get answered. You don't have to work it full-time to stay in it.
How is the fee divided, and what does Rule 1.04 require? +
Rule 1.04(f) lets lawyers in different firms divide a fee only if the split is by proportion of work or by joint responsibility, the client consents in writing to the terms before the referral or association, and the total fee is reasonable. The written consent has to name the lawyers, say whether the division is by work or by joint responsibility, and state each share or how it's figured. The exact dollars depend on the division of labor, which we agree on with you at the start.
What kinds of oilfield cases is this for? +
Serious injury and wrongful-death cases out of upstream oil and gas work: drilling and workover rigs, frac operations, well servicing, tank batteries, pipelines, and the trucking that ties it together. These are the cases where Chapter 95, a Master Service Agreement, and a chain of contractors are all in play, and where the worker who got hurt usually worked for a contractor rather than the operator.
Who actually does the work? +
The team does, with you as involved as you choose. Guy Muller and The Stewart Law Firm carry the litigation and the case expenses. Stephen W. Stewart has handled catastrophic injury, wrongful-death, and product cases since 1997. You keep the relationship with the client who trusted you in the first place.
Is the first conversation confidential? +
Yes. Your client's information is protected under Rule 1.05, and a call to talk through a possible association doesn't obligate you or your client to anything.
How do I start a conversation? +
