What Is an Alibi Defense?

An alibi is one of the oldest and simplest forms of defense in criminal law. It means you claim you were somewhere else when the crime took place, making it impossible for you to have committed the offense. This might sound straightforward, but successfully presenting an alibi in court requires careful planning, timely action, and strict attention to Nevada's procedural rules.

How Does Alibi Evidence Work in Nevada?

If you have evidence that places you somewhere else at the time of a crime—such as surveillance footage, receipts, GPS data, or testimony from witnesses who saw you elsewhere—this is called alibi evidence. In Nevada, simply announcing that you have an alibi is not enough. You must disclose it to the prosecution in advance. This means, well before trial, your attorney needs to let the prosecutor know not only that you plan to claim an alibi, but also where you claim to have been, and who will testify to support that claim.

Why Do I Have to Tell the Prosecutor About My Alibi?

You might wonder why the defense must reveal its strategy. Nevada law requires this to prevent surprise at trial and to give the prosecution a fair chance to investigate your claim. If you wait until the last minute to present an alibi, the judge can prevent your witnesses from testifying, or even strike your entire defense. These rules exist to ensure both sides have time to prepare and that the trial proceeds fairly.

What Must Be Disclosed—and When?

The disclosure of an alibi defense is not a vague notice; it is a formal process. Your attorney must give written notice to the prosecutor, listing the specific place you claim to have been, as well as the names and addresses of any witnesses you intend to call to support your alibi. This must be done within the time frame set by the court, usually shortly after the initial court appearances and well before trial. The prosecution, in turn, is required to disclose any evidence they have to contradict your alibi.

Common Pitfalls: How Alibi Defenses Go Wrong

One of the most common mistakes is missing the deadline to disclose an alibi. Courts can—and often do—bar late-disclosed alibi witnesses from testifying. Another error is providing vague or incomplete information. If the details about your whereabouts or your witnesses are unclear, the prosecutor can challenge your notice as insufficient, risking exclusion of key evidence. Sometimes, defendants think an alibi is “automatic,” only to find the court will not let them present it at all because their lawyer did not follow the procedural rules.

There is also the risk of witness problems. If a witness suddenly changes their story, disappears, or turns out to be unreliable, the defense can unravel quickly. Furthermore, giving the prosecution advance notice of your witnesses allows them time to investigate and prepare cross-examination, so the credibility of your alibi must be rock solid.

How a Skilled Attorney Protects Your Alibi Defense

Navigating these rules is not just a matter of filling out paperwork. An experienced criminal defense attorney will know how to properly investigate and prepare your alibi, file all required notices on time, and ensure your defense is not excluded for technical reasons. A good attorney will also anticipate how the prosecution might attack your alibi, and prepare your witnesses accordingly.
