After an arrest, the DA has anywhere from 48 hours to several years to file charges, depending on whether you’re sitting in jail, whether the case is state or federal, and which offense is under review. The short version: if you’re in custody, a prosecutor typically needs to act within about two days; if you’re out of custody, the review can stretch for weeks or months; and the absolute outer limit is the statute of limitations, which runs from one year for minor offenses to no limit at all for the most serious ones.
The 48-Hour Rule When You’re in Custody
When someone is arrested without a warrant and held in jail, the Constitution requires that they be brought before a judge for a probable cause determination promptly. In County of Riverside v. McLaughlin, the Supreme Court held that a jurisdiction providing that hearing within 48 hours of arrest will generally satisfy the Fourth Amendment.1Justia U.S. Supreme Court Center. County of Riverside v McLaughlin, 500 US 44 (1991)
Technically, 48 hours is the deadline for a judge to confirm probable cause, not for the DA to file charges. In practice the two events collapse together, because the hearing usually coincides with the initial charging decision. If the government misses the window, it bears the burden of justifying the delay, and weekends or administrative backlogs don’t count as valid excuses.1Justia U.S. Supreme Court Center. County of Riverside v McLaughlin, 500 US 44 (1991)
One important boundary: if you were cited and released, or posted bail shortly after arrest, the 48-hour clock doesn’t apply to you. The prosecutor has more time to decide.
Timelines When You’re Out of Custody
Out-of-custody cases move slower, sometimes much slower. Prosecutors handling hundreds of new arrests every week triage by who is sitting in jail, and cases where the defendant is at home tend to slide down the priority list. Straightforward misdemeanors can still be charged within days. Complex investigations can take weeks or months of review before the DA is confident enough to file.
The absence of a court date doesn’t mean the case went away. Prosecutors in some jurisdictions take months to decide on out-of-custody matters, and charges can appear long after the arrest itself feels like old news.
Federal Cases: The 30-Day Indictment Rule
Federal cases come with the most concrete deadline. The Speedy Trial Act requires that an indictment or criminal information be filed within 30 days of the defendant’s arrest or service of a summons.2Office of the Law Revision Counsel. 18 US Code 3161 – Time Limits and Exclusions
The number looks tight, but the Act carves out substantial “excludable time.” Pretrial motions, continuances granted in the interest of justice, delays caused by an unavailable witness or co-defendant, and periods when a case is under advisement all pause the clock.3Department of Justice Archives. 628 Speedy Trial Act of 1974 If the government blows the deadline without a valid exclusion, the charges must be dismissed, and a judge decides whether the dismissal is with prejudice (permanent) or without (refile allowed).
For federal felonies, the Fifth Amendment generally requires prosecution by grand jury indictment, which needs at least 12 jurors to concur.4Legal Information Institute (LII) / Cornell Law School. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury Federal misdemeanors, and felonies where the defendant waives the grand jury right, can proceed by an information filed directly by the prosecutor.5Legal Information Institute (LII) at Cornell Law School. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information A judge can seal an indictment until the defendant is arrested, so a person under investigation may not know that charges have already been approved.
The Statute of Limitations Sets the Outer Deadline
The statute of limitations is the hard ceiling. Once it expires, prosecution is permanently barred. In federal court, the general rule is five years for any non-capital offense.6Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Offenses punishable by death have no statute of limitations at all.7Office of the Law Revision Counsel. 18 US Code 3281 – Capital Offenses
State deadlines follow a similar pattern with different numbers. Misdemeanors typically carry one-to-two-year deadlines. Common felonies generally fall in the three-to-six-year range. Murder carries no time limit in every state. Some states also eliminate the deadline for other serious offenses, like sexual assault of a minor.
The clock can be paused, or “tolled.” Federal law provides that no statute of limitations applies to a person who is a fugitive from justice.8Office of the Law Revision Counsel. 18 USC 3290 – Fugitives From Justice Some states also toll the period while charges are pending against the defendant in another case, or while the defendant’s identity is unknown.
Why Filing Can Take Longer Than You Expect
Case complexity is the single biggest factor. A shoplifting arrest with surveillance footage and a cooperating store employee can be charged in a day or two. A financial fraud investigation with thousands of documents, or a homicide with multiple witnesses and forensic evidence, might take weeks or months of review.
Pending lab work is another common bottleneck. DNA analysis, toxicology reports, and digital forensics from phones or computers all take time, and crime labs in many jurisdictions carry significant backlogs. Prosecutors often won’t commit to specific charges until those results come back.
It’s also worth remembering that police make arrests, but prosecutors decide whether to file charges. The DA reviews the case file independently and can file the exact charges the police recommended, file different charges, decline to file anything, or send the case back for more investigation.
What Happens if the DA Misses a Deadline
The consequences depend on which deadline was missed. If the statute of limitations expires before charges are filed, the case is dead. No court can revive it.
Missing the 48-hour probable cause window for someone in custody has a different result. The remedy is release from jail, not dismissal of the case. The prosecutor can still file charges later, as long as the statute of limitations hasn’t run.1Justia U.S. Supreme Court Center. County of Riverside v McLaughlin, 500 US 44 (1991) Getting released because the government dragged its feet does not mean you’re in the clear.
Violating the federal Speedy Trial Act’s deadlines results in dismissal of the charges, with the judge deciding whether refiling is allowed. A Sixth Amendment speedy trial violation, by contrast, always results in dismissal with prejudice, permanently ending the case.9Constitution Annotated, Library of Congress. Amdt6.2.1 Overview of Right to a Speedy Trial
If the DA Declines to File Charges
Sometimes the prosecutor reviews a case and decides not to file, because the evidence is weak, a witness is uncooperative, or charges aren’t warranted. A decision not to prosecute is not the same as an acquittal. The DA can revisit the case and file charges later if new evidence surfaces, as long as the statute of limitations hasn’t expired.
If charges were filed and later dropped, the legal term is “nolle prosequi,” which resets the case to where it stood before charges existed. It leaves the door open for the government to refile. Only a dismissal “with prejudice” permanently blocks the same charges from being brought again.
One boundary that surprises people: your arrest record doesn’t disappear just because the DA declined to file. The arrest itself stays on your record unless you take affirmative steps to have it removed, usually through a petition for expungement or record sealing. Some states impose a waiting period of a year or more after the arrest before you can file. Background checks for employment, housing, and licensing can surface an arrest even without a conviction, so the step is worth taking.
What You Can Do While Waiting
The gap between arrest and a charging decision feels powerless, but it’s a window where the right moves can change the outcome. Get a defense attorney involved immediately. During the review period, an attorney can contact the DA’s office and present information that might persuade the prosecutor not to file, including witness statements, alibis, or context missing from the police report. Pre-filing advocacy is most effective before the prosecutor commits, not after.
Preserve any evidence that supports your side. Surveillance footage gets overwritten, text messages get deleted, and witnesses’ memories fade. Secure copies now rather than hoping the material will still be available months later.
Don’t discuss the case with anyone other than your lawyer. Check in with your attorney periodically, especially if you’re out of custody, because prosecutors can and do file charges long after the arrest itself feels like ancient history.
