Texas Criminal Defense Motions

How Texas Criminal Motion Practice Works

In a Texas criminal case, almost every meaningful decision a judge makes starts with a motion — a formal request asking the court to do something the law permits. You file most motions in writing with the district or county clerk, serve a copy on the prosecutor, and ask the court to set the matter for a hearing. A few motions, such as a trial objection or a request for a mistrial, are made orally in the moment, but the substantive motions that can reshape a case are almost always written, filed, and argued in front of a judge.

Texas motion practice draws on three bodies of law, and knowing which one governs a request tells you the deadline, the legal standard, and who carries the burden. The Code of Criminal Procedure supplies most statutory motions — suppression under article 38.23, dismissal under articles 28.061 and 32.01, and bond relief under article 17.15, among many others. The Texas Rules of Evidence control what a jury may hear and drive motions in limine and expert-reliability challenges under Rule 702. The Texas Rules of Appellate Procedure govern post-verdict motions, including the motion for new trial under Rule 21.

Most contested motions are resolved at a pretrial hearing. Article 28.01 allows the court to set a pretrial hearing to decide suppression questions, pleadings, and evidentiary disputes before the jury is brought in, and it entitles you to at least ten days' notice of that setting. At the hearing, the party carrying the burden presents evidence — testimony, records, video — and the judge rules. On a motion to suppress, for instance, once you show the search happened without a warrant, the State generally must justify it.

Not every motion looks the same. Some, such as a motion for continuance or a change-of-venue motion, must be sworn — supported by an affidavit — before a court will consider them, and others require you to attach the records or transcripts the judge needs in order to rule. The defense files most of the motions that drive a criminal case, but the State files motions too, so defending a case also means responding to the prosecution's requests, not just pressing your own. The form a motion must take, and what it must include, is set by the same statute or rule that creates the right.

Two features make motion practice decisive rather than merely procedural. First, a favorable ruling often strips out the very evidence the State needs, which can force a dismissal or a far stronger plea position without a trial ever starting. Second, a motion is how you preserve an issue for appeal: if the judge denies your motion and you later ask a higher court to review that decision, the written motion, the hearing transcript, and the court's order are exactly what the appellate court examines. A right never asserted in a motion is usually a right you cannot raise later.

When a judge rules on a significant motion, the decision may arrive as a docket notation, a signed order, or — on a motion to suppress — written findings of fact and conclusions of law that you can request and that frame any later appeal. Because those findings can control how a reviewing court reads the record, asking for them at the right moment is part of litigating the motion, not an afterthought. In short, the timing and drafting of each motion matter as much as the argument inside it.

Pretrial, Trial, and Post-Trial Motions in Texas Courts

Texas criminal motions sort into three phases, and each phase carries its own timing rules and legal standards. Understanding where a motion falls tells you when it must be filed and what the court is being asked to decide.

Pretrial motions are the largest and often the most consequential group. This is where you attack the evidence and the charge before a jury is ever seated. Motions to suppress physical evidence, statements, and identifications live here, as do motions to quash the charging instrument under articles 27.08 and 27.09, motions to set aside the case under articles 28.061 and 32.01, discovery demands under the Michael Morton Act, bond-reduction motions under article 17.15, competency and insanity issues under chapters 46B and 46C, change-of-venue motions under article 31A.004, and continuances under article 29.03. A single pretrial ruling can end a prosecution or sharply weaken the State's proof.

Trial motions are made once the case is called and the jury process begins. A motion in limine seeks an advance ruling that keeps prejudicial matters from being mentioned in front of the jury without first approaching the bench. Motions to sever — defendants under article 36.09, or offenses under Penal Code section 3.04 — are resolved as trial is organized. During the evidence, you may move for an instructed verdict of acquittal when the State's proof is legally insufficient, request a jury shuffle under article 35.11, or move for a mistrial when an incurable error makes a fair verdict impossible.

Post-trial motions come after a verdict or plea and are governed largely by the Rules of Appellate Procedure. The motion for new trial under Rule 21 asks the trial court to vacate the verdict on grounds such as newly discovered evidence or jury misconduct, and it carries a firm 30-day deadline. A motion in arrest of judgment under Rule 22 attacks a judgment for a defect apparent on the record before the sentence becomes final. A motion to withdraw a plea seeks to undo a guilty or no-contest plea shown to be involuntary or unknowing.

Some motions echo across phases, and recognizing the connections lets you build a record early. A legal-insufficiency argument you raise at trial through a motion for an instructed verdict, for example, tracks the same sufficiency question a court can revisit after the verdict; a suppression issue litigated pretrial can resurface in a motion for new trial if it was preserved. Laying that groundwork at the first opportunity often makes the later motion stronger, because the appellate record is built from what you did at each stage.

The phase matters because deadlines and standards shift with it. Pretrial motions turn on statutory filing dates and pretrial-hearing settings; trial motions must be made contemporaneously to preserve the issue; post-trial motions run on short, strict clocks measured from sentencing. Filing the right motion in the wrong phase — or missing the window entirely — can forfeit an otherwise strong argument, which is why sequencing the motions is itself part of the defense.

Suppression and Dismissal in Texas

Suppression and dismissal are the two ways a motion can end a Texas case before trial — one removes the State's evidence, the other removes the prosecution itself.

The engine of suppression is article 38.23, the Texas statutory exclusionary rule. It directs that evidence obtained by an officer or other person in violation of the law — an illegal stop, a warrantless search without a valid exception, an unlawful arrest — may not be admitted against you at trial. When the facts are disputed, article 38.23 also allows the jury to be instructed to disregard evidence it finds was illegally obtained. In practice, you file a written motion to suppress, the court sets a hearing under article 28.01, and the State must justify the police conduct. A false or reckless statement in a search-warrant affidavit can be attacked the same way, forcing the court to retest probable cause without the tainted averments.

One feature sets the Texas rule apart from its federal counterpart: article 38.23 reaches evidence obtained illegally by anyone, not only by government officers, so a private person's unlawful conduct can trigger exclusion as well. The remedy matters because it is practical — when the stop, the seizure, or the physical evidence falls, the case built on it often falls with it, which is why a contested suppression hearing is frequently the pivotal moment in a prosecution.

Statements and confessions have their own suppression track under articles 38.22 and 38.21. Article 38.22 governs the admissibility of an accused's statements: a custodial statement generally must follow the required warnings and a knowing, voluntary waiver, and an oral custodial statement usually must be electronically recorded to come in. Layered on top is Miranda v. Arizona, which bars using a statement from custodial interrogation conducted without the familiar warnings. A statement shown to be involuntary — the product of coercion — is inadmissible regardless of the warnings.

Dismissal motions attack the case itself rather than a single piece of evidence. A motion to quash challenges the charging instrument: article 27.08 addresses defects of substance, such as an indictment that fails to allege an offense or give adequate notice of what you must defend against, while article 27.09 addresses defects of form. If the instrument is fatally defective, the court can quash it.

A motion to set aside seeks dismissal for a legal bar that has nothing to do with the wording of the charge. Article 32.01 requires the State to secure an indictment by the next term of court or within 180 days; if it does not, you can move to set the accusation aside and seek release. Article 28.061 provides for dismissal tied to certain speedy-indictment and speedy-trial failures. Because the consequences differ — a quashed indictment can sometimes be re-presented, while some set-aside grounds bar reprosecution — matching the right motion to the right defect is essential.

Discovery and Bond in Texas

Two of the most practical pretrial fights in a Texas case are about information and liberty: what the State has to show you, and whether you have to sit in jail while the case is pending.

Discovery is governed by the Michael Morton Act, article 39.14 — named for the Texas man whose wrongful conviction spurred the Legislature to open the State's files by law. On a timely request, the statute requires the State to produce the offense reports, witness statements, recordings, photographs, and physical or expert evidence in its possession. The court can set the terms and timing of that production. The Act is broad, and it moved Texas from a narrow discovery regime to open-file practice by statute rather than local custom.

Subsection (h) is the heart of it. It imposes on prosecutors a standing, affirmative duty to disclose any evidence that tends to negate guilt or reduce punishment — exculpatory, impeaching, or mitigating material — whether or not the defense asks for it. That statutory duty runs alongside the constitutional rule of Brady v. Maryland, which requires disclosure of material favorable evidence. Together they let you move to compel production and, when disclosure comes late or not at all, to seek a remedy from the court. The court's tools range from ordering late production and granting a continuance to prepare, to limiting or excluding evidence the State failed to disclose in time. Because the duty under article 39.14 is continuing, it does not expire at a single deadline — new material must be handed over as it surfaces.

Bond is the second fight. Article 17.15 sets the rules for fixing the amount of bail: bail must be high enough to give reasonable assurance you will appear, but it may not be used as an instrument of oppression, and the court must weigh your ability to make bail along with the nature of the offense and the safety of the community. A motion to reduce bond asks the court to apply those factors and lower an excessive amount, or to grant a personal bond. A related motion can ask the court to modify the conditions of release — travel limits, contact restrictions, or monitoring requirements — that are more burdensome than the case warrants.

Article 17.151 adds a separate and important lever. It is a release-for-delay rule: if you are detained and the State is not ready for trial within the statutory period — 90 days from the start of detention for a felony, with shorter periods for misdemeanors — the court must release you, either on a personal bond or by reducing bail to an amount you can make. The rule turns on the State's readiness, not the strength of its case, so even a serious charge can qualify. It is enforced through a bond motion or a habeas application under article 11.24, and it makes the State's own delay a basis for your release.

Trial and Post-Trial Motions in Texas

Once a case reaches the courtroom, a second set of motions shapes what the jury sees and, if there is a conviction, whether it stands.

A motion in limine is the classic trial-management tool. It asks the judge for an advance ruling that neither side may mention a specified prejudicial matter — a prior conviction, an extraneous offense, a gruesome photograph — until the court has been approached outside the jury's hearing. A limine ruling is preliminary: it keeps the jury from hearing something before you can object, but you still must object when the evidence is actually offered to preserve the point for appeal. The Texas Rules of Evidence, including Rule 103, supply the framework.

Severance keeps a trial from becoming unfairly stacked. Under article 36.09, jointly charged co-defendants can be tried separately where a joint trial would prejudice one of them — for example, when a non-testifying co-defendant's confession would spill over. Under Penal Code section 3.04, a defendant facing multiple offenses joined from a single criminal episode generally has the right to sever them into separate trials, subject to the statute's exceptions.

A change of venue moves the trial to another county when local conditions make a fair, impartial jury unlikely — typically because of saturating pretrial publicity or community-wide prejudice. The governing statute is article 31A.004, which was recodified from the former article 31.03 effective January 1, 2025; motions filed now should cite the new article. The request is supported by affidavits, and the State may file counter-affidavits that put the issue to a hearing.

Expert evidence is tested through a Kelly challenge. Under Texas Rule of Evidence 702 and Kelly v. State, the trial judge acts as a gatekeeper and may hold a hearing on whether scientific or forensic testimony is reliable enough to reach the jury — examining whether the underlying theory is valid, whether the technique applying it is valid, and whether the technique was properly applied in your case. Unreliable forensic methods can be excluded before the jury ever hears them.

After a verdict, two motions can still change the outcome. The motion for new trial under Texas Rule of Appellate Procedure 21 asks the trial court to vacate the verdict on grounds such as newly discovered evidence, jury misconduct, or a verdict against the great weight of the evidence, and it must be filed within 30 days of sentencing. The motion in arrest of judgment under Rule 22 attacks a judgment for a defect apparent on the face of the record — a charging-instrument flaw that survived the verdict, or a conviction for an offense that was never charged — before the sentence becomes final.

Timing controls these motions as much as substance. A jury-shuffle request under article 35.11 must be made before voir dire begins; a mistrial must be sought promptly when the harmful event happens, or the complaint is lost; and a motion in arrest of judgment must be filed before the sentence is final. Even a strong ground fails if it is raised at the wrong moment, so mapping each motion to its window is part of trying the case.

Key Texas Motion Deadlines

Deadlines decide motions as surely as the law behind them. A well-founded motion filed a day late can be waived, and a right tied to a specific window disappears when the window closes. Texas does not impose one master deadline for all motions; instead, each motion runs on the clock its governing statute or rule sets, and local rules and a judge's scheduling order can tighten those clocks further.

Three of the most important benchmarks appear below. They are the ones defendants most often ask about — how long the State has to indict, how much notice you get before a pretrial hearing, and how long you have to seek a new trial after sentencing.

Article 32.01 protects against being held indefinitely on an unindicted accusation: if the grand jury does not act within the statutory period, you can move to set the case aside, though the State may in some situations re-present the charge. Article 28.01 governs the pretrial hearing where suppression and other motions are decided, and its ten-day notice provision gives you time to prepare. Rule 21.4's 30-day window for a motion for new trial is short and unforgiving — it begins the day sentence is pronounced, so it should be calendared immediately.

A missed deadline is rarely curable, and the consequences are concrete. An untimely motion for new trial cannot extend the trial court's authority over the case, and a pretrial motion filed after the court's cutoff may be treated as waived. The safest practice is to identify, at the very first setting, every clock that runs against your specific charge and to docket them all at once rather than one at a time.

Other motions carry their own deadlines that are easy to miss: the insanity-defense notice under article 46C.051 is due 20 days before trial, and many courts set a single cutoff date for all pretrial motions. Treat the entries above as common reference points, not a complete calendar. Deadlines vary by court and case — confirm the specific dates that apply to your case with counsel before relying on any of them.

How L&L Files Motions in Texas Cases

At L and L Law Group, motion practice starts with the record. We read the offense reports, video, lab results, and the rest of the State's file produced under article 39.14, then measure what happened against what the law required at each step — the stop, the search, the interrogation, the charging instrument, and the bond setting. The issues that surface become written motions.

From there the work is methodical. We draft each motion to its governing statute or rule, attach the affidavits or records it requires, request a pretrial hearing under article 28.01, and prepare the testimony and exhibits needed to carry the burden at that hearing. When a ruling can shape an appeal, we ask the court for findings of fact and conclusions of law so the record is clean. We track the deadlines that decide these motions — the 20-day insanity notice, the 30-day new-trial window, and the pretrial cutoffs your court imposes — so no issue is lost to timing.

Because a motion is also how an issue is preserved for review, we treat the written motion and the hearing record as part of your long-term defense, not just the argument in front of the trial judge. If a motion is denied, that record is what a higher court would later examine. We keep you informed at each step — what was filed, what the court decided, and what the ruling means going forward — because your decisions about trial, plea, and appeal turn on how the motions come out.

No lawyer can ethically promise a particular outcome, and we do not. What we can do is identify every motion your facts support, file it correctly, and argue it. If you are facing charges in Collin, Denton, Dallas, or a surrounding county and want your case reviewed for these issues, call (972) 370-5060 or email info@landllawgroup.com to arrange a consultation.

How Courts Have Shaped Texas Motion Practice

Motions draw their force from controlling case law as much as statutes. These decisions—verified against primary sources—frame the practice indexed on this page.

• Mapp v. Ohio, 367 U.S. 643 (1961) — Evidence obtained through searches and seizures that violate the Fourth Amendment is inadmissible in state criminal prosecutions, extending the exclusionary rule to the states.
• Franks v. Delaware, 438 U.S. 154 (1978) — A defendant may obtain a hearing challenging a search-warrant affidavit by substantially showing it contained a knowing or reckless falsehood necessary to probable cause.
• Miranda v. Arizona, 384 U.S. 436 (1966) — Before custodial interrogation, police must warn a suspect of the rights to silence and counsel; statements taken without a valid waiver are inadmissible.
• Brady v. Maryland, 373 U.S. 83 (1963) — Prosecutors violate due process by suppressing evidence favorable to the accused that is material to guilt or punishment, regardless of good or bad faith.
• Barker v. Wingo, 407 U.S. 514 (1972) — Speedy-trial claims are assessed by balancing four factors: length of delay, reason for the delay, the defendant's assertion of the right, and prejudice.
• Jackson v. Virginia, 443 U.S. 307 (1979) — Evidence is legally sufficient if, viewed most favorably to the prosecution, any rational trier of fact could find the essential elements beyond a reasonable doubt.
• Blockburger v. United States, 284 U.S. 299 (1931) — Two statutory provisions are separate offenses for double-jeopardy purposes if each requires proof of a fact the other does not.
• Kelly v. State, 824 S.W.2d 568 (Tex. Crim. App. 1992) — Under Texas Rule 702, not Frye, a proponent must prove novel scientific evidence reliable and relevant by clear and convincing evidence.
