In Texas, a notice of nonsuit with prejudice is a document a plaintiff files to voluntarily and permanently dismiss their own lawsuit. The “with prejudice” language is what makes it final: once filed, the plaintiff cannot bring those claims against that defendant again in any Texas court. A plain nonsuit, by default, is without prejudice and leaves refiling open; adding “with prejudice” closes that door for good.
What “With Prejudice” Actually Does
A dismissal with prejudice operates as a final judgment on the merits, even though no judge or jury ever ruled on who was right. That triggers res judicata, sometimes called claim preclusion, which blocks the plaintiff from relitigating the dismissed claims.
Texas applies a broad version of the doctrine. The bar reaches not only the specific claims the plaintiff filed, but also related claims arising from the same facts that the plaintiff could have raised and didn’t. A different legal theory built on the same underlying dispute will not get around it. If you settle a personal injury case and nonsuit with prejudice, a later suit for property damage from the same incident is likely gone too if it wasn’t included.
Why a Plaintiff Would File One
Giving up the right to refile sounds like a losing move, and plaintiffs rarely do it without getting something in return. The most common trigger is a settlement. When the parties resolve the case through negotiation, the defendant almost always requires a dismissal with prejudice as a condition of payment. The defendant is paying to end the dispute permanently, not to face the same lawsuit again later.
Other situations come up. A plaintiff may want to permanently drop some claims while pursuing others. A plaintiff whose case has fallen apart may prefer a voluntary with-prejudice dismissal to an adverse judgment on the record. The decision to nonsuit is generally within the plaintiff’s control.
When You Can File It
Under Texas Rule of Civil Procedure 162, a plaintiff can take a nonsuit at any point before finishing their presentation of evidence at trial, not counting rebuttal evidence. That gives a wide window, running from the day the lawsuit is filed through the late stages of trial.1South Texas College of Law. Texas Rule of Civil Procedure 162 – Dismissal or Nonsuit
The nonsuit takes effect without a court order. The judge’s permission is not needed, and the judge cannot deny it as long as it’s filed within the allowed window. This is one of the few absolute, unilateral rights a party has in litigation.
The Affirmative Relief Limit
A plaintiff cannot use a nonsuit to erase the defendant’s independent claims. If the defendant filed a counterclaim, cross-claim, or any other request for affirmative relief, that claim survives the plaintiff’s nonsuit and continues in the same court.1South Texas College of Law.

A general denial of the plaintiff’s allegations does not count as affirmative relief. The test is whether the defendant’s filing could independently produce a recovery if the plaintiff’s case disappeared. A counterclaim for breach of contract qualifies. An answer that simply says the plaintiff is wrong does not.
How to File the Notice
The plaintiff or their attorney drafts a document titled “Notice of Nonsuit” or “Notice of Nonsuit With Prejudice.” It should identify the court, case number, case style, and parties. The critical piece is the explicit statement that the dismissal is with prejudice. Without those words, the dismissal defaults to without prejudice, which has very different consequences.
The signed notice is filed with the clerk of the court where the lawsuit is pending. Rule 21a then requires service of a copy on every party who has answered or been served, through the court’s e-filing system, mail, personal delivery, or commercial delivery service. The document must include a certificate of service confirming delivery.2South Texas College of Law. Texas Rule of Civil Procedure 21a – Methods of Service
What Happens After You File
The nonsuit is effective the moment it’s filed. The court will eventually enter a formal order of dismissal, which closes the case on the docket and starts post-judgment deadlines, but the legal effect of the nonsuit does not wait for that order.
Rule 162 directs the clerk to tax all court costs against the party who took the nonsuit, unless the court orders otherwise. In practice, the plaintiff pays the accumulated filing fees, service fees, and similar charges, regardless of who was winning.1South Texas College of Law.

Pending motions for sanctions, attorney’s fees, or other costs are not wiped out by the dismissal. The court keeps authority to decide those motions after the rest of the case is gone.1South Texas College of Law. Texas Rule of Civil Procedure 162 – Dismissal or Nonsuit
Attorney’s Fees Exposure
Texas follows the American Rule: each side pays its own attorney’s fees unless a statute or contract says otherwise. A nonsuit with prejudice does not automatically entitle the defendant to reimbursement.
Chapter 38 of the Civil Practice and Remedies Code, the main Texas fee-shifting statute, allows recovery of attorney’s fees only for certain claim types, including breach of contract, rendered services, and unpaid labor, and has historically been available primarily to claimants rather than defendants.3State of Texas.

Contracts are a different story. Many commercial agreements include a prevailing-party clause, meaning the winner recovers legal fees from the loser. Texas courts have recognized that when a plaintiff nonsuits with prejudice, the defendant qualifies as the prevailing party under such a clause. The fee claim comes from the contract itself, not from the nonsuit.
Why This Decision Is Nearly Impossible to Undo
Most plaintiffs underestimate how final this is. Unlike a without-prejudice dismissal, where refiling is simple, a with-prejudice dismissal creates a res judicata bar that extends to related claims the plaintiff could have brought. There is no “take it back” option built into the rule.
Setting aside a with-prejudice dismissal is extraordinarily difficult. A party would have to file a motion to vacate and show grounds such as fraud, fundamental mistake, or a settlement that fell apart after the notice was filed. Courts are deeply reluctant to undo these dismissals, because finality is the entire point.
For a plaintiff in settlement negotiations, the practical rule is simple. Do not sign or file a nonsuit with prejudice until the settlement funds have actually been received or payment is fully secured. Once the notice hits the clerk’s desk, your leverage is gone.
