Affidavit of Non Prosecution Texas: How It Impacts Your DWI Defense

A DWI arrest can be overwhelming, especially when another person is involved—but you don’t have to face it alone. You might hear about a document called an Affidavit of Non-Prosecution (ANP) and wonder if it’s the key to making your case simply vanish.

In a nutshell, an ANP is a sworn, formal statement from the complaining witness—the "victim"—telling the prosecutor they don't want to press charges and wish for the case to be dropped. While not a guaranteed dismissal, it can be a powerful tool in your defense.

Understanding the Affidavit of Non-Prosecution in Texas

A DWI arrest is an isolating and stressful ordeal, but it’s a situation you don't have to navigate by yourself. When a DWI incident involves another party, such as in an Intoxication Assault case, the alleged victim's feelings about the case can become a critical part of your defense strategy. The Affidavit of Non-Prosecution is the official tool they can use to make their wishes known.

Think of the ANP as the victim’s formal request, sent directly to the District Attorney's office, to shut down the legal proceedings. But it’s crucial to grasp one key legal principle right from the start: the State of Texas is the one pressing charges against you, not the individual.

Who Actually Controls the Case?

Once a police report is filed and charges are brought, the case is officially titled "The State of Texas vs. [Your Name]." This means the prosecutor, representing the state, has the final say on whether to move forward or not.

So, an ANP doesn't automatically get your case dismissed. It won't force the prosecutor's hand. But what it does do is give your defense attorney powerful ammunition to fight for you.

A skilled DWI lawyer can use this document strategically to:

  • Show the prosecutor their key witness won't cooperate. A prosecution's case often hinges on the victim's testimony. If they're unwilling to help, the case gets much weaker.
  • Negotiate for a better deal, like a charge reduction. The ANP can be a compelling reason for a prosecutor to offer a lesser charge just to resolve the case.
  • Argue for a complete dismissal. In cases where the other evidence is shaky, an ANP might be the final push needed to convince the State to drop everything.

Why Its Role Is Critical but Not Absolute

While the ANP isn’t a magic wand, it absolutely changes the dynamic of your case. It sends a clear signal to the prosecutor that their main witness is reluctant, making a conviction at trial a much tougher uphill battle for them. This creates leverage and opens the door for negotiations that can protect your record and your future.

It's extremely important that the document is signed voluntarily, without any threats, pressure, or coercion. Trying to force a victim to sign an ANP can backfire spectacularly, leading to serious new charges like witness tampering. This process must be handled delicately and with proper legal guidance.

Keep in mind, the ANP is a tool for your criminal case. It has no direct impact on the separate civil process for your driver's license. You can learn more about that in our detailed guide on the Administrative License Revocation process in Texas.

How an ANP Realistically Impacts Your DWI Case

When the alleged victim in your case signs an Affidavit of Non-Prosecution, it's a huge step in the right direction. But let's be clear about what it does—and what it doesn't do. Think of the ANP as a powerful letter of recommendation for dismissing your case. It sends a loud and clear signal to the prosecutor that their star witness wants out, but it does not force their hand.

The District Attorney’s office is legally required to look at the ANP, but only alongside every other piece of evidence. That includes police reports, body cam footage, 911 calls, photos, and your own criminal history. Their job is to protect public safety, and since the case is legally filed by "The State of Texas," they can—and often do—push forward even when a victim wants to drop it.

The Prosecutor's Perspective

A prosecutor isn't just going to toss a case because one piece of paper tells them to. They have to weigh the victim's wishes against everything else they have. Is there overwhelming evidence? Was the alleged offense particularly serious?

For example, if you're facing a family violence charge in Texas after a heated argument and your partner signs an ANP, it's definitely helpful. But prosecutors have the final say because the state, not the victim, is the one bringing the charges. In big counties like Tarrant County, it's rare for authorities to drop a case based only on an ANP; it’s just one more factor in their calculation. You can get more insights on how Texas prosecutors view these affidavits and understand why the state's control over the case is absolute.

This is exactly why having an experienced defense attorney is so important. We know how to present the ANP not as a simple request, but as proof of a weak, unprovable case that’s destined to fail at trial.

The table below breaks down what a prosecutor is likely thinking when they see an ANP land on their desk.

ANP Influence vs. Prosecutor's Discretion

Factors That Strengthen an ANP Factors That Weaken an ANP
No independent witnesses to the event. Multiple other witnesses saw what happened.
Little to no physical evidence (injuries, property damage). Obvious physical injuries documented in photos or medical reports.
The complainant has a history of retracting statements. Your own criminal history includes similar offenses.
The ANP is detailed and sounds genuine. The 911 call or body cam footage is compelling and emotional.
The initial police report contains inconsistencies. You made incriminating statements to the police.
The complainant's story has changed over time. The alleged offense was particularly severe (e.g., use of a weapon).

Ultimately, a prosecutor's job is to secure convictions. If the ANP makes that job look incredibly difficult, they're far more likely to consider a dismissal.

Using the ANP to Highlight Weaknesses

The real power of an affidavit of non-prosecution in Texas comes from how it's used as a strategic tool. Our job is to take this document and use it to create leverage and apply serious pressure on the prosecution.

We don't just hand it over. We present it to the DA and make a compelling argument that:

  • Their star witness is now unreliable. A person who signed a sworn statement wanting to drop the case is going to be a terrible, unconvincing witness on the stand.
  • The rest of their evidence isn't enough. Without a cooperative witness, small gaps in the police report or a grainy video suddenly become huge problems for the state's case.
  • Taking this to trial is a waste of taxpayer money. We frame it as an unwinnable case that isn't in the best interest of justice for them to pursue.

An Affidavit of Non-Prosecution isn't just a piece of paper; it’s a crowbar we use to pry open the cracks in the prosecution's case. It's not about what the document says—it's about how it proves their case is falling apart. We use it to show them that a dismissal is their smartest move.

This approach completely changes the conversation. It’s no longer about what the victim wants, but about the practical, real-world problems the prosecutor will face in a courtroom. It’s a strategic pivot that opens the door to a dismissal, a reduced charge, or a better plea deal that protects your record and your freedom.

How to Properly Draft and Submit the Affidavit

For an Affidavit of Non-Prosecution to have any real sway with the District Attorney's office, it has to be drafted and submitted perfectly. A sloppy, poorly written, or improperly filed document is worse than useless—it’s a liability that can hurt your case. Getting this right demands precision and a solid grasp of legal standards.

Putting together a powerful affidavit isn’t as simple as jotting down a quick note. It's a formal, sworn statement that must contain specific details to be taken seriously by the court. Every single piece of information matters, from the case number to the exact phrasing of the victim’s request.

Essential Components of a Valid ANP

To make sure the affidavit is legally sound and carries maximum weight, it has to include a few key pieces of information. Leave any of these out, and you can bet the prosecutor will toss it aside without a second thought. A properly drafted affidavit of non-prosecution in Texas will always contain:

  • The Defendant's Information: This means the full, legal name of the person accused of the crime.
  • The Case and Court Details: You need the official case number and the specific court where the case is filed (e.g., County Criminal Court No. 5 of Harris County).
  • The Complainant's Statement: This is the heart of the document—a clear, direct statement from the alleged victim declaring they don't want to participate in the prosecution.
  • A Statement of Voluntariness: The affidavit must state, in no uncertain terms, that the victim is signing of their own free will, without being forced, threatened, or coerced.

The absolute most critical step is getting the document signed in the presence of a Notary Public. That notary’s seal and signature are what verify the signer's identity and confirm the statement was made under oath. It’s what makes the paper a powerful legal tool.

The Critical Importance of Voluntary Action

Let me be crystal clear: the alleged victim's decision to sign the affidavit must be 100% voluntary. Even a whisper of pressure or intimidation from the defendant can lead to disastrous consequences.

If a prosecutor even suspects you threatened, bribed, or strong-armed the complainant into signing, they won't just ignore the affidavit. They’ll likely hit you with new, far more severe felony charges for witness tampering. That’s a serious crime that can instantly turn a misdemeanor DWI case into a legal nightmare.

"I, [Victim's Full Name], am the complaining witness in the case of The State of Texas vs. [Defendant's Full Name], Case Number [Case #], currently pending in [Court Name]. I am signing this affidavit of my own free will. I do not wish to testify or participate in the prosecution of this case, and I respectfully request that the District Attorney's office dismiss all charges against the defendant."

This sample language shows you the kind of direct, unambiguous tone you need. The focus is squarely on the victim's independent decision, which is exactly what gives the document its credibility.

Filing the Affidavit with the District Attorney

Once the affidavit is drafted, signed, and notarized, it has to be filed correctly with the District Attorney's office handling your case. Just mailing it in or dropping it at the front desk isn't going to cut it.

An experienced DWI defense attorney will hand-deliver the affidavit directly to the prosecutor assigned to the case. This move ensures it becomes part of the official case file and, just as importantly, creates an opening for your attorney to start negotiations. They can use that moment to argue why the affidavit reinforces the case for dismissal, while also pointing out other weaknesses in the state’s evidence. You can learn more about how evidence, like DWI breathalyzer records, is scrutinized in a criminal case.

Having a lawyer manage this whole process is non-negotiable. We make sure the document is drafted perfectly, signed without a hint of coercion, and submitted strategically to give you the best possible shot at a favorable outcome. Trying to do this on your own is a huge risk, full of critical mistakes that professional guidance can easily help you avoid.

How Prosecutors Look at an Affidavit of Non-Prosecution

To get an Affidavit of Non-Prosecution to actually work, you have to get inside the head of the person on the other side of the table. A prosecutor’s decision to drop a case isn't random; they follow a specific playbook when an ANP lands on their desk. Their job is to represent the State of Texas and protect the public, which means they’re going to scrutinize that document from every angle.

Understanding their mindset is everything. They aren't just reading the alleged victim's words; they're sizing up the entire case. A sharp defense lawyer knows how to present the ANP in a way that makes dismissal seem like the only logical—and just—outcome.

The Key Factors in a Prosecutor's Analysis

When a prosecutor gets an ANP, they start a methodical evaluation. They're weighing the complainant's wishes against several critical factors, but it all boils down to one question: "If this case went to trial tomorrow, could we win it without this witness?"

Here are the main things they'll be looking at:

  • Severity of the Offense: A case with minor scrapes or no injuries is a world away from one involving serious bodily harm. An ANP carries a lot more weight in a low-level misdemeanor than it does in a felony Intoxication Assault case.
  • Strength of Other Evidence: The prosecutor will take a full inventory of every other piece of evidence. Do they have good body cam footage? Photos of injuries? A damning 911 call? Statements from other witnesses who aren't the complainant? If the state has a mountain of evidence that stands on its own, the ANP loses a lot of its power.
  • The Defendant's Criminal History: Your past plays a huge role. An ANP is far more persuasive if you have a clean record. But if you have previous arrests or convictions for similar offenses, especially assault or DWI, the prosecutor will be much more hesitant to dismiss the charge.
  • Credibility of the Complainant: They’re also going to size up the person who signed the affidavit. Have they changed their story before? Does the ANP seem genuine? Any hint of coercion or a fishy motive can make the whole document worthless in their eyes.

This decision tree shows the first basic checkpoints an affidavit must clear before a prosecutor even starts their deeper analysis.

As the chart makes clear, if the ANP wasn't signed voluntarily or properly notarized, it’s dead on arrival. Those are the absolute non-negotiables.

Why Independent Evidence Is the Real Game-Changer

The biggest hurdle an ANP has to overcome is the existence of independent evidence. A prosecutor's main goal is to secure a conviction if they believe a crime happened. If they can prove their case without the victim ever taking the stand, they will almost always move forward.

A prosecutor's job is to represent The State of Texas. They are trained to build cases that can withstand an uncooperative witness. The ANP is our tool to show them why their case is too weak to stand on its own.

Think about the reality in Texas. Over 150,000 family violence incidents are reported each year. While an affidavit of non-prosecution is filed in an estimated 25-35% of these assault cases in major cities like Houston, the dismissal rates aren't nearly that high. That's because prosecutors will use every other piece of evidence they have—identity, intent, injury—to prove the crime, even if the complainant wants nothing to do with it. You can learn more about how prosecutors use evidence when an ANP is filed to see these dynamics in action.

The Strategic Legal Argument

This is where having a strategic Houston DWI lawyer becomes critical. We don’t just file the ANP and hope for the best; we build a powerful legal argument around it. We present it to the prosecutor not as a simple request, but as concrete proof that their case has fatal weaknesses.

Our argument will hammer these points home:

  1. Lack of Corroboration: We make it clear that without the victim, there is no one else to back up the state’s story.
  2. Witness Unreliability: We explain that even if they subpoena the complainant, a witness who signed a sworn ANP is a prosecutor’s nightmare on the stand. They can be easily impeached, making them a liability.
  3. Interests of Justice: We frame the dismissal as the most just and efficient outcome for everyone involved, especially for first-time offenders where the complainant just wants to move on.

By getting inside the prosecutor’s head, we can anticipate their moves and counter their arguments, turning that ANP from a piece of paper into a powerful weapon for dismissal.

Using an ANP as a Strategic Defense Tool

A well-timed Affidavit of Non-Prosecution is so much more than a piece of paper—it's a real strategic asset in your defense. While it’s no magic wand that makes a case disappear, in the hands of a skilled Houston DWI lawyer, it becomes a powerful negotiating tool. It can pry open doors to outcomes that are worlds better than a conviction.

At The Law Office of Bryan Fagan, PLLC, we don't just file the paperwork and hope for the best. We weave the ANP into a broader, more comprehensive defense strategy designed to protect your future.

This document sends a clear signal to the prosecutor: their star witness is no longer on their side. That shift creates leverage, letting us argue for resolutions that might have been completely off the table before. We don't see the ANP as just a request to drop charges; we see it as the first move in a strategic effort to dismantle the state’s case against you.

Arguing for Charge Reductions

One of the most effective ways we leverage an ANP is to push for a major reduction in charges. This is especially critical in cases where you might be facing a felony. For instance, a serious charge like Intoxication Assault could potentially be negotiated down to a lesser misdemeanor when the complaining witness has formally stated they don't want to move forward.

A prosecutor knows that taking a felony case to trial with a reluctant or uncooperative witness is a huge gamble. We use the ANP to drive that risk home, presenting them with a choice: either proceed with a shaky, unwinnable case or agree to a reduced charge that better reflects the available evidence and the victim's wishes. This proactive approach can mean the difference between a life-altering felony conviction and a much more manageable misdemeanor.

Securing Favorable Plea Agreements

Even when a full dismissal isn't on the table, an affidavit of non-prosecution in Texas can be instrumental in securing a much better plea agreement. This often means negotiating for outcomes like deferred adjudication.

So, what is deferred adjudication?

  • It’s a special kind of probation where you plead "guilty" or "no contest," but the judge puts off a final finding of guilt.
  • If you successfully finish the probation period, the case is dismissed, and you avoid a permanent conviction on your record.
  • This can be a massive win, as it may allow you to later petition for a non-disclosure, which would seal the record from public view.

Without the leverage an ANP provides, a prosecutor has little reason to offer such a favorable deal. We use it to show them they risk losing at trial, making deferred adjudication a reasonable and just compromise for everyone involved.

Building a Comprehensive Defense Strategy

The ANP rarely works in a vacuum. Its true power is unlocked when it’s combined with other strong defense strategies. We don't just file the affidavit; we build a compelling narrative around it that shows the prosecutor why dropping the case is the right call.

Our approach involves:

  1. Challenging Other Evidence: We file motions to suppress evidence from an unlawful traffic stop or from field sobriety tests that weren't administered correctly.
  2. Highlighting Inconsistencies: We point out contradictions between what the ANP says and what’s in the initial police report, which further damages the credibility of the state's case.
  3. Presenting a Complete Picture: We use the ANP to help tell your side of the story, explaining the full context and showing that pursuing charges isn't really in the interest of justice.

In Texas criminal courts, especially for DWI-related assaults, an affidavit can be a game-changer. Defense practices show its effectiveness can vary, with dismissal rates often depending on the county and a defendant’s history. For example, criminal defense analyses in Travis County indicate that prosecutors dismiss roughly 45% of misdemeanor assault cases after receiving an ANP, but only if the victim fully recants and the defendant has no prior offenses. You can discover more insights about how Texas prosecutors respond to these affidavits and see the statistics for yourself.

By combining the ANP with aggressive legal challenges, we create overwhelming pressure on the prosecution, making it clear that dropping the charges is their most logical path forward.

Common Questions About Affidavits of Non Prosecution

When you're navigating the legal system, especially after a DWI arrest, questions pop up left and right. The Affidavit of Non-Prosecution is one of those legal tools that often brings a mix of hope and confusion. Let's clear the air with straightforward answers to the questions we hear most often about using an affidavit of non-prosecution in Texas.

Can the Victim Be Forced to Testify After Signing an ANP?

Yes, they absolutely can. The State can issue a subpoena, which is a court order that legally forces someone to show up and testify. Ignoring it isn't an option—that person could face serious legal trouble of their own.

But this is where a signed ANP becomes a game-changer for your defense attorney. Once the complaining witness is on the stand, your lawyer can pull out that sworn affidavit they signed earlier. This creates a powerful moment in court, allowing your attorney to highlight the massive difference between what they're saying now and their previous sworn statement wanting to drop the case. This can seriously damage their credibility with the judge or jury and can sometimes unravel the prosecution's entire case.

What Happens if I Pressure the Victim to Sign an ANP?

Let me be crystal clear: you should never try to persuade, threaten, or coerce a complaining witness into signing an Affidavit of Non-Prosecution. Doing so is not only a terrible idea, but it can get you slapped with a new, serious felony charge for witness tampering.

The victim's decision to sign has to be 100% their own, completely free of any influence from you, your friends, or your family. An experienced Houston DWI lawyer knows how to navigate this delicate situation. We can open the right lines of communication—ethically and legally—to ensure the ANP is obtained in a way that the court will actually respect, instead of it backfiring and digging you into a deeper hole.

The integrity of an Affidavit of Non-Prosecution hinges on its voluntary nature. Any hint of coercion renders it useless and exposes you to severe new criminal charges. The process must be handled with professional legal oversight.

Does an ANP Impact My ALR License Suspension Hearing?

No, it doesn't. An Affidavit of Non-Prosecution has zero direct effect on your Administrative License Revocation (ALR) hearing. It's critical to understand that after a DWI arrest, you're fighting two completely separate battles.

  1. The Criminal Case: This is the fight to avoid a conviction, jail time, and fines. The ANP is a tool used here, where the standard of proof is "beyond a reasonable doubt."
  2. The ALR Hearing: This is a civil process run by the Texas Department of Public Safety (DPS). Its only job is to decide whether your driver's license gets suspended.

Because the ALR hearing is an administrative proceeding, it plays by a different set of rules and has a much lower standard of proof. The ANP, which speaks to the victim’s wishes in the criminal case, is simply not considered relevant evidence in the fight to save your license.


A DWI arrest can be a frightening and confusing experience, but you have rights and options.
