Statute of Limitations and Notice Requirements in Texas Oilfield Cases

By Guy Muller  ·  Injury lawyer, San Antonio  ·  Updated July 2026

The short and plain version

  • A court deadline can end even the best and strongest cases before anyone ever hears it. No court hearings. No jury verdicts. The case just legally disappears before it can ever start.
  • Most Texas injury and wrongful death lawsuits must be filed within two years of the injury or the death.
  • Workers' comp moves faster and by a different set of rules. You must tell or notify your employer within 30 days, and file the state claim within one year.
  • Some situations can change the clock or pause it from ticking, including injuries to children, diseases that take years to show up, and claims against government entities. That last one gets even shorter, not longer.
  • The evidence has its own clock, and it runs faster than every legal one.
  • If you think a deadline might be coming up quick, talk to a lawyer right now, not later. Early costs you nothing, and it is the best move, in my humble opinion. Late can cost the whole case and throw it out the window like the injury or incident never happened.

1. Why a deadline can end a strong case before anyone hears it

There is a guaranteed way to lose even the best case without ever losing an argument. You just wait too long to do anything. The deadline passes, and a claim that was worth real money, and could have made a real impact on the safety of the community and the industry, becomes worth nothing, and nobody can fix it.

If you don’t have a lawyer, nobody calls to warn you, either. The company won’t remind you, and its insurance carrier definitely won’t. Their lawyers know every one of these dates the way you know your kids’ birthdays, and against a strong case, patience is one of the cheapest moves they have. Time costs them nothing and could save them everything. And it costs you everything you were owed, and it puts our community in danger in the future if the people responsible for your injuries are not held accountable for their wrongs.

Plain English: "statute of limitations"

A "statute of limitations" is the legal deadline for filing a lawsuit. Each type of claim gets a set number of years, and the countdown usually starts the day you're hurt. File after the deadline and the company can ask the court to throw your case out no matter how strong it is, and the court will almost always have to do it. In Texas, the main deadline for injury cases is two years.

And a deadline is different from every other fight in a case. Fault gets argued, the medicine gets argued, the money gets argued hard, and a qualified lawyer can win those arguments. But a blown deadline usually doesn’t get argued at all, because the law treats it as an “affirmative defense” (a complete answer the company can raise even when it was dead wrong on the facts), and once the date is gone, it works.

So out of everything in this guide, this page covers the one problem that being early almost always prevents and being late almost never fixes.

By the numbers 328 dead

Every one of these deaths started a legal clock. In 2024, 65 workers were killed on the job in the oil and gas extraction industries (drilling, extraction, and well-support work) across the country, and 328 were killed over the five years from 2020 through 2024. In Texas alone, 36 workers died in the mining, quarrying, and oil and gas extraction sector in 2024. For every one of those families, and for every worker who got hurt and lived, the deadlines on this page started running that same day, whether anybody explained them or not.

2. The two-year rule for most injury and wrongful death claims

Start with the big one. A Texas law, section 16.003 of the Civil Practice and Remedies Code, gives you two years to file most personal injury lawsuits. The clock usually starts on the day you were hurt: the day of the blowout, the fall from the derrick, the crash on the lease road. Two years from that day is generally the last day to file suit against the companies responsible.

For a wrongful death case, the same statute answers the question families ask most. The two years generally runs from the date of death, not from the date of the injury that caused it. The statute says the claim “accrues on the death of the injured person” (“accrues” is the legal word for when a claim is born and its clock starts). So when a worker fights in a burn unit for three months and then passes, the family’s two years starts at the death. The worker’s own claims run on their own timeline, and that difference matters, as you’re about to see.

The Texas Supreme Court has been strict about that death date. In Moreno v. Sterling Drug, the Court held that the “discovery rule” (an exception covered below that can delay some clocks) does not apply to wrongful death claims, because the legislature picked the start date itself: the death.

Now, two traps hide inside the two-year rule, and both of them have ended real cases.

Trap one: the family’s case stands on the worker’s case. In Russell v. Ingersoll-Rand, the Texas Supreme Court held that wrongful death and survival claims are “entirely derivative” of the worker’s own rights. In plain words, the family stands in his legal shoes. If his own deadline ran out while he was still alive, the family’s case can already be over on the day he dies, no matter how fresh the grief is. So when a death comes months or years after the injury that caused it, this question needs a lawyer’s eyes immediately. Who can bring a death case and what it covers is explained in the wrongful death guide.

There is one piece of mercy in the statute book here. Section 16.062 pauses the clock on the worker’s own claims for up to 12 months after a death, so a family doesn’t lose the survival claim (the worker’s own claim, continued by his estate) while they’re still standing at the graveside. But the pause has a catch. If an executor or administrator of the estate qualifies sooner, the clock starts again at that moment. Probate and deadlines are tangled together in these cases, and they need to be handled together.

Trap two: “filing” means filing the lawsuit in court, and even that isn’t always enough. In Proulx v. Wells, the Texas Supreme Court explained that a suit filed on time still fails unless the plaintiff also uses due diligence in getting the defendant served (formally handed the court papers). A case filed on the last day and then left sitting can die even though it technically beat the deadline. The Court also laid out how that fight runs. Once the company shows service happened after the deadline, the injured worker has to explain every gap in the effort to serve. If that explanation raises a real dispute, the burden moves back to the company to prove the explanation fails as a matter of law. And none of these stop the clock: calling a lawyer, opening a claim with an adjuster, filling out company paperwork. Only the lawsuit does.

3. The workers’ comp deadlines: notice and claim

Everything above is about lawsuits. Workers’ comp is a different system with its own calendar, and its deadlines are much shorter.

Plain English: "notice requirement"

A "notice requirement" is a deadline for formally telling somebody about the injury, separate from any deadline for filing a case. Miss a filing deadline and you lose the courthouse. Miss a notice deadline and you can lose the claim before it ever exists.

If your employer carries workers’ comp insurance, the Texas Labor Code gives you two deadlines, and you need to hit both.

First, the 30-day notice. Under section 409.001, you (or someone acting for you) must tell your employer about the injury within 30 days of the date it happened. Telling a supervisor or a manager counts. If the injury is an occupational disease (an illness caused by the work itself), the 30 days starts when you knew or should have known the illness may be related to the job.

Second, the one-year claim. Under section 409.003, you must also file a formal claim for compensation with the Texas Division of Workers’ Compensation (the state agency that runs the workers’ comp system) within one year of the injury. There is a state form for it, DWC Form-041. Telling your boss is a different step, and so is talking to the company’s insurance adjuster. Neither one is the claim.

Miss either deadline and the statutes are blunt about what happens: the employer and its insurance carrier are “relieved of liability,” which means they can walk away from the claim, unless you fit an exception. And watch this trap, because the two deadlines carry different lifelines. A late notice to the employer can be excused three ways: the employer, a supervisor, or the carrier already had actual knowledge of the injury, the state finds good cause for the delay, or nobody contests the claim. A late claim filed with the state gets only two of those: good cause, or nobody contesting it. The company already knowing about your injury does not excuse a late claim filing. But exceptions are things lawyers fight about for months. Deadlines are things you can just meet. Meet them.

Death cases have their own version. Under section 409.007, a claim for death benefits must be filed within one year of the worker’s death. The exceptions are narrow: minor beneficiaries, legal incompetence, and good cause.

One more thing, because Texas is different from every other state here. If your employer carries no workers’ comp at all (a “non-subscriber,” which is legal in Texas and common in the oil patch), the comp deadlines above don’t control your claim against that employer. That claim is a regular negligence lawsuit running on the two-year clock. But be careful, because many non-subscribers run their own private injury benefit plans with their own reporting rules, and some of those plans demand notice within days. So report every injury in writing right away no matter who your employer is, and get a copy of any plan documents. What a non-subscriber case looks like is covered in the non-subscriber guide.

4. Special situations: the discovery rule, kids, slow diseases, and the government

Some situations move the clock. None of them are automatic, and every one of them gets fought over. So treat everything in this section as a reason to ask a lawyer early, never as a reason to wait.

The discovery rule.

Plain English: "the discovery rule"

The "discovery rule" is a narrow exception that can delay the start of a limitations clock when a person could not reasonably have known they were injured. When it applies, the clock starts when you knew, or reasonably should have known, about the injury and its likely cause, instead of the day the harm was done.

The Texas Supreme Court has kept this exception narrow. In S.V. v. R.V., the Court said the discovery rule is generally reserved for injuries that are “inherently undiscoverable” (the kind of harm even a careful person is unlikely to find in time) and “objectively verifiable” (provable with hard evidence, something stronger than somebody’s memory). A broken back on the rig floor is discovered the moment it happens, so no discovery rule. A disease that grows in silence for years is a different conversation.

Slow diseases. For latent occupational diseases (illnesses that hide for years before they show), the clock has its own rule. Silicosis, the lung disease caused by breathing silica dust, including frac sand, is the classic example. In Childs v. Haussecker, the Texas Supreme Court held that the clock starts when two things come together: symptoms show up strongly enough that a reasonable person would know they’re injured, and the person knows, or with reasonable care should know, the injury is likely work-related. You don’t always get to wait for a confirmed diagnosis, and a bare suspicion doesn’t automatically start the clock either. It’s fact by fact. On top of the case law, the legislature wrote a special statute for silica and asbestos claims, section 16.0031, that ties accrual to the earlier of the exposed person’s death or the serving of a qualifying medical report. If your case involves breathing dust, the deadline question is a specialist question, so ask it early. The disease itself is covered in the frac and silica guide.

Kids. Under section 16.001, a person younger than 18 is under a “legal disability,” and the time of that disability generally doesn’t count against them. In plain words, a child’s own clock is usually paused until their 18th birthday, and the two years run from there. One caution, though. The pause protects the child’s own claim, while claims that belong to the adults in the family run on the normal clocks.

The badly hurt. That same statute covers a person “of unsound mind.” A worker in a coma, or one whose brain injury leaves him unable to manage his own affairs, may be under a legal disability that pauses his clock. May. The statute generally ignores a disability that begins after the clock has already started, these fights are won and lost on medical records, and no family should assume the pause applies to them. Get it answered instead.

Government entities. If any responsible party is a governmental unit (a city, a county, the state, or one of its agencies), everything speeds up. Under the Texas Tort Claims Act, chapter 101 of the Civil Practice and Remedies Code, the government is entitled to formal written notice of the claim within six months of the incident, and the notice has to reasonably describe the injury, the time and place, and what happened. Cities are allowed to shorten that period in their charters, and some demand notice within a few months or less. The law does contain an exception when the government already had actual notice of the death or injury, but proving that after the fact is its own fight, and a terrible thing to bet a case on. Out here this usually means a collision with a county truck, a road crew’s work zone, or publicly owned land. The government isn’t the usual defendant in the oil patch, but when it’s in the case, the six-month clock, or a shorter city one, controls the early weeks.

Plain English: "tolling"

"Tolling" is the legal word for pausing a limitations clock. Being under 18, being of unsound mind, and the 12-month pause after a death are the main tolling rules on this page. The company will fight about whether tolling applies, so nobody should plan a case around it without legal advice.

What Texas courts have said

A short, plain summary of Texas Supreme Court decisions that shape deadline questions. This is legal background, not a prediction about any specific case.

  • Moreno v. Sterling Drug (1990). The two-year wrongful death clock runs from the date of death, and the discovery rule does not delay it.
  • Russell v. Ingersoll-Rand (1992). Wrongful death and survival claims stand entirely on the worker's own rights. If his claim was already time-barred while he was alive, the family's claims are barred with it.
  • S.V. v. R.V. (1996). The discovery rule is reserved for injuries that are both "inherently undiscoverable" and "objectively verifiable." It is a narrow exception.
  • Childs v. Haussecker (1998). For latent occupational diseases like silicosis, the clock starts when symptoms would put a reasonable person on notice of an injury the person knows, or should know, is likely work-related. A confirmed diagnosis is not always required first.
  • Proulx v. Wells (2007). Filing suit on time is not enough by itself. The plaintiff must also act with due diligence in serving the defendant.

The plain takeaway: Texas courts enforce these deadlines as written, and the exceptions are narrow and fact-heavy. The safe course never changes. Ask early.

5. Why “evidence deadlines” are just as real

The law gives most cases two years. The evidence never promises you two years.

Think about what actually proves an oilfield case: the drilling records and daily reports, the JSAs (job safety analysis forms, the pre-job safety paperwork), the gas monitor logs, the truck’s electronic data, camera footage, the equipment itself, and the memories of the hands who watched it happen. Now think about what happens to each of those over a few months. The rig moves to the next lease. The equipment gets repaired, scrapped, or “lost.” Electronic data and camera footage get overwritten on a schedule, sometimes within weeks. And the crew scatters across three states chasing the next job while memories fade and phone numbers change.

None of that waits two years. Some of it doesn’t wait two weeks.

The companies understand this better than anyone, and it’s part of why waiting serves them. Their side of the file starts the same day you get hurt: the safety man’s report, the carrier’s investigation, the photographs, the recorded statements, all of it gathered while you’re still in a hospital bed. And remember who is holding the records. The same companies whose choices are in question are the ones deciding what gets kept.

A lawyer working for you can push back early. One of the first tools is a preservation letter (a formal demand that a company keep specific evidence instead of destroying it, because destroying evidence after notice can get a company punished by the court). But a preservation letter only protects what still exists on the day it’s sent, and that is the whole argument for moving early in one sentence.

So keep the two questions separate. “When must I file?” is usually a two-year question. “When should someone start protecting my case?” was a today question from the day it happened. What those first weeks should look like, step by step, is in the first 30 days guide.

6. What this means for you and your family

What this means for you and your family

Here is the plain version of everything above.

Most Texas injury lawsuits must be filed within two years of the injury. Most wrongful death lawsuits must be filed within two years of the death.

If the employer carries workers' comp, tell the employer within 30 days and file the state claim within one year. A death benefits claim gets one year too.

If a city, county, or state agency had any part in it, formal written notice may be due within six months, and sometimes sooner.

Some clocks pause: for children, for workers too hurt to manage their own affairs, for diseases that take years to show. None of that is automatic, and all of it gets fought over.

And the evidence clock runs faster than every legal clock on this page.

If you might have a case, find out your dates now, while every option is still open. Early costs you nothing. Late can cost you the case.

7. Questions to ask any lawyer you are considering

You don’t have to take anybody’s word on your deadlines, including mine. Test any lawyer you talk to. These questions will show you fast whether they take the calendar as seriously as your case deserves.

Questions to ask before you hire a lawyer about deadlines
  • Ask them to list every deadline in your case: the two-year one, the workers' comp notice and claim dates, any government notice, and any deadline that runs against a family member's claim.
  • Ask what they will do this month to preserve evidence, and whether preservation letters will go out before anything else is decided.
  • Ask when your clock actually started. If your case involves a disease or a death that came long after the injury, ask them to explain the accrual date and what could move it.
  • Ask what happens if a deadline is close: can they file in time and still investigate properly, and who does that work?
  • Ask whether any government entity could be in the case, and whether a six-month or shorter notice applies.
  • Ask about their experience with oilfield cases, whether they work with experienced co-counsel when needed, how the fee works, what expenses they cover up front, and what happens if the case doesn't recover.

A lawyer who knows this work will answer every one of those without flinching. A lawyer who gets weird and defensive about them just answered the most important one.

Common questions

How long do I have to file an oilfield injury claim in Texas? +

For most injury lawsuits, two years from the date of the injury. Wrongful death lawsuits generally run two years from the date of death. Workers' comp is much faster: report to your employer within 30 days and file the state claim within one year. Some situations change these dates in both directions, so treat every one of them as a reason to talk to a lawyer early.

Is the deadline different for a wrongful death case? +

The deadline is still two years, but it generally starts on the date of death instead of the date of injury. Two cautions. The family's case stands on the worker's case, so a deadline that ran out while he was alive can bar the family's claim entirely. And workers' comp death benefits have a separate one-year deadline. Families should get answers early, even if they are not ready to decide anything.

What are the workers' comp deadlines? +

Two main ones. Tell your employer within 30 days of the injury, and a supervisor counts. Then file a formal claim with the Texas Division of Workers' Compensation within one year. For a disease caused by the work, both clocks start when you knew or should have known it may be tied to the job. The escape hatches are different for each. A late notice can be excused if the employer already knew about the injury, if the state finds good cause, or if nobody contests the claim. A late claim can be excused only by good cause or an uncontested claim. Death benefit claims are due within one year of the death.

What is the discovery rule? +

A narrow exception that can delay the start of a deadline when a person could not reasonably have known they were hurt. Texas courts save it for harm that is hidden by its nature and provable with hard evidence, like a disease that develops years after the exposure that caused it. It gets fought over case by case, so nobody should skip a deadline hoping the discovery rule will save them.

What if the injured worker is a minor? +

Texas law generally pauses a child's own deadline until their 18th birthday, and the two years usually run from there. The pause protects the child's claim only. Claims that belong to the parents or other adults run on the normal clocks. Evidence does not wait either, so a family should never sit on a child's case just because the law allows more time.

What if I think my deadline already passed? +

Talk to a lawyer anyway, and do it now. The real start date is not always the obvious one, a pause may apply, and different claims in the same case can have different clocks, so one door being closed does not mean every door is. And if every deadline has in fact passed, you deserve to hear it from someone who checked, instead of carrying the question around for years. The conversation is free.

Are the deadlines different if a government entity is involved? +

Yes, and they are shorter. When a claim runs against a governmental unit, like a city, county, or state agency, Texas law generally requires formal written notice within six months of the incident, and some city charters cut that shorter. The notice has to describe the injury, the time and place, and what happened. If there is any chance a government entity was involved, treat the case as urgent from day one.
