How long the district attorney has to file charges depends on which deadline you’re asking about. If someone has just been arrested, the prosecutor usually has a matter of days, often 48 to 72 hours in state cases and up to 30 days in federal cases, to file formal charges or release the person. If no arrest has happened yet, the prosecutor has until the statute of limitations expires, which is typically one to two years for misdemeanors, three to ten years for most felonies, and no limit at all for murder.1Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses The exact numbers depend on where the offense allegedly happened and what the charge is.
The Deadline After an Arrest
When someone is already in custody, the short clock is the one that matters. Under the federal Speedy Trial Act, prosecutors must file an indictment or information within 30 days of arrest. If no federal grand jury has been in session during that window, the deadline extends to 60 days.2Office of the Law Revision Counsel. 18 USC Ch 208 – Speedy Trial
State deadlines run shorter. Many states require charges to be filed within 48 to 72 hours of a warrantless arrest, though the exact timing and how weekends and holidays are counted varies by jurisdiction. Miss the deadline, and the court orders the person released from custody.
That release is not the end of the case. The prosecutor can still file charges later, as long as the statute of limitations hasn’t run. The post-arrest clock limits how long you can be held without charges, not whether charges can eventually be brought.
The Statute of Limitations
The statute of limitations is the outer boundary. It sets the maximum number of years a prosecutor has to bring charges after a crime occurs, and once it expires, the case is off the table for good.
The clock starts on the date the offense was committed, not the date it was discovered or reported. If a burglary happens on March 1 and the limitation period is five years, the prosecutor has until March 1 five years later to file. What counts is when the charging document is filed with the court. An arrest before that date doesn’t extend the deadline, and a trial that happens years after filing is still valid so long as the case was initiated in time.
Time Limits by Crime Severity
Misdemeanors
Less serious offenses carry the shortest deadlines. In most jurisdictions, prosecutors have one to two years from the date of the offense to file misdemeanor charges. Simple assault, petty theft, and minor drug possession typically fall in this range. If more than two years have passed without charges on a misdemeanor investigation, the window has likely closed.
Felonies
Federal law sets a general five-year statute of limitations for non-capital felonies.3Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital State felony deadlines range widely, from about three years for lower-level felonies up to ten years or more for serious violent crimes. Fraud, theft, and drug trafficking cases usually sit in the three-to-seven-year band, but the specific number depends entirely on the state and the particular charge.
Crimes With No Deadline
The most serious offenses have no statute of limitations. A prosecutor can bring charges 5, 25, or 50 years later.
- Murder and capital offenses. Under federal law, any offense punishable by death can be prosecuted at any time, and every state follows the same principle for murder.1Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses
- Sexual offenses against children. Federal law permits prosecution for child sexual abuse during the victim’s lifetime, or for ten years after the offense, whichever is longer. Many states have gone further and removed the deadline entirely.
- Other serious offenses. Depending on the jurisdiction, crimes like kidnapping and treason may have no time limit either.
Events That Pause or Extend the Clock
Several circumstances stop the statute of limitations from running, giving prosecutors more time than the baseline suggests. Lawyers call this tolling.
Fleeing the Jurisdiction
If a suspect leaves the state or country to avoid prosecution, the clock pauses. Federal law is direct: no statute of limitations protects anyone fleeing from justice.4Office of the Law Revision Counsel. 18 USC 3290 – Fugitives From Justice Most states have equivalent rules. Time spent outside the jurisdiction doesn’t count, and the clock resumes when the person returns or is caught.
The Discovery Rule
Some crimes aren’t apparent when they happen. Embezzlement schemes, investment fraud, and identity theft can stay hidden for years. Many jurisdictions apply the discovery rule, which delays the start of the limitation period until the crime was discovered or reasonably should have been discovered. A fraud victim who learns about the theft three years later may still have the full limitation period running from that later date.
DNA Identification
Federal law effectively doubles the statute of limitations when DNA testing identifies a suspect in a felony case. The additional time equals the original limitation period and runs from the date the DNA match is made.5Office of the Law Revision Counsel. 18 USC 3297 – Cases Involving DNA Evidence Many states have adopted similar rules, particularly for sexual assault. Cold cases that sat unsolved for years can be revived when a database produces a hit.
Crimes Against Minors
When the victim is a child, most jurisdictions toll the statute of limitations until the victim reaches adulthood. Children rarely have the ability or awareness to report crimes committed against them. Under federal law, prosecutions for sexual or physical abuse of a child under 18 can be brought during the victim’s lifetime or within ten years of the offense, whichever gives the prosecutor more time. Many states have eliminated the deadline entirely for childhood sexual abuse.
Due Process Limits on Deliberate Delay
Even when the statute of limitations is still running, the government cannot deliberately sit on a case to gain a tactical advantage. In United States v. Lovasco, the Supreme Court held that time spent on a thorough investigation does not violate due process, but intentional delay designed to prejudice the defendant can.6Justia. United States v Lovasco, 431 US 783 (1977)
Winning that argument is hard. You have to show two things: that the delay caused concrete harm to your defense, such as specific lost evidence or unavailable witnesses, and that the government delayed for improper reasons. Vague claims that memories have faded won’t succeed, and courts give prosecutors wide latitude when they were genuinely investigating. In extreme cases, where a prosecutor waits years despite having everything needed to file, the protection can produce a dismissal.
What Happens When the Clock Runs Out
Once the statute of limitations expires, the case is dead. New evidence, cooperating witnesses, and public pressure cannot revive it. The government is permanently barred from prosecuting that offense.
There is a catch. The statute of limitations is an affirmative defense. A court will not raise it on its own. You or your attorney must assert it, and failing to raise it before or during trial can forfeit the argument entirely.7Congress.gov. Statute of Limitation in Federal Criminal Cases – An Overview It is one of the strongest defenses in criminal law when it applies, but only if someone actually makes it.
One scenario catches people off guard. A dismissal without prejudice means the prosecutor dropped the case but reserved the right to refile. If the statute of limitations is still running when that happens, the prosecutor can bring the same charges again later, provided the filing beats the deadline. A dismissal without prejudice is not an acquittal, and it does not end the threat of prosecution.
