How Long Can You Be Held in Jail Without Being Convicted?
Explore how legal timelines, rights, and court procedures impact the length of pretrial detention in the U.S. justice system.
Being arrested does not mean someone has been convicted of a crime. Many people spend days, weeks, or even months in jail before their case is resolved, sometimes without ever going to trial. This raises a fundamental question about the American justice system: How long can the government legally hold someone without proving guilt?
The answer affects not only those facing charges but also the principles of fairness and due process. Understanding the limits on pretrial detention clarifies the rights individuals have after arrest and the safeguards intended to prevent indefinite incarceration without conviction.
Probable Cause Requirements
Before an individual can be held long-term following an arrest, the government must meet the probable cause standard rooted in the Fourth Amendment, which protects against unreasonable seizures. An arrest is a seizure, so it must be based on probable cause – sufficient facts for a reasonable person to believe a crime was committed and the arrested person committed it. This standard requires more than suspicion but less evidence than needed for conviction.
While an officer may determine probable cause for an initial arrest, especially one made without a warrant, the Fourth Amendment demands judicial oversight for continued detention. The Supreme Court established in Gerstein v. Pugh (1975) that individuals arrested without a warrant are entitled to a prompt judicial determination of probable cause. A neutral judge, not just a prosecutor, must review the basis for holding someone shortly after the arrest.
The court clarified the timing in County of Riverside v. McLaughlin (1991), stating that probable cause determinations within 48 hours of a warrantless arrest generally satisfy the promptness requirement.1Office of Justice Programs. Judicial Probable Cause Determinations After County of Riverside v. McLaughlin Delays beyond 48 hours are presumed unreasonable unless the government can show an emergency or extraordinary circumstance. Gathering more evidence is typically not a valid reason for exceeding this timeframe. This hearing is usually informal, focused solely on whether sufficient reason exists to continue detention, not on guilt or innocence. If the judge finds no probable cause, the individual must generally be released, though charges might still be filed later if probable cause is established.
Arraignment and Filing Charges
After the initial justification for detention, the case moves toward formal accusation. This involves prosecutors filing charges and the defendant’s first court appearance on those charges, known as an arraignment.
Prosecutors initiate this phase by filing a charging document, such as a complaint (often based on a police statement), an information (a formal accusation by the prosecutor, common for misdemeanors or waived felonies), or an indictment (issued by a grand jury, required for federal felonies unless waived). Filing this document formally begins the criminal case.
Following the filing of charges, the defendant is scheduled for arraignment. At this hearing, the defendant is informed of the specific charges, advised of their constitutional rights (including the right to counsel), and asked to enter a plea (commonly guilty, not guilty, or no contest).2United States Department of Justice.

Procedural rules aim to prevent undue delay in filing charges and holding the arraignment. For example, the federal Speedy Trial Act generally requires an indictment or information to be filed within 30 days of arrest.3U.S. Code via Legal Information Institute. 18 U.S. Code § 3161 – Time Limits and Exclusions Federal rules also mandate bringing an arrested person before a judge “without unnecessary delay.”4United States Courts. Federal Rules of Criminal Procedure While practices vary, arraignments often occur within a few days of arrest, sometimes within 48 or 72 hours (excluding weekends and holidays), especially if the defendant is in custody. Delays can extend the time someone is held before formally responding to the accusations in court.
Bail or Bond Hearing Timelines
Once probable cause is confirmed, the focus shifts to whether the accused will remain incarcerated pending trial. This is decided at a bail or bond hearing, separate from the probable cause review. Its purpose is to determine if the person can be released back into the community and under what conditions.
Many jurisdictions require this hearing promptly after arrest, often within 24 to 72 hours, sometimes excluding weekends and holidays. Federal rules require release or detention to be addressed at the initial court appearance, which must occur “without unnecessary delay.” The Supreme Court, in United States v. Salerno (1987), recognized that prompt hearings are part of the due process required for pretrial detention decisions.5Congress.gov | Library of Congress.

The outcome determines whether the pre-conviction period is spent in custody or at liberty. Judges consider factors like the seriousness of the charge, criminal history, community ties, risk of flight, and potential danger to the community. The Eighth Amendment prohibits “excessive bail,” interpreted in Stack v. Boyle (1951) as bail higher than reasonably needed to ensure the defendant’s appearance at trial.6FindLaw. Eighth Amendment Protection Against Excessive Bail and Fines However, Salerno affirmed that detention without bail is permissible based on compelling interests like public safety, provided procedural safeguards are met.
If release is deemed appropriate, conditions are set, ranging from release on personal recognizance to financial bonds or non-financial terms like curfews or electronic monitoring. If no conditions can reasonably assure appearance or community safety, the court may order detention without bail until trial.
Speedy Trial Provisions
The duration of pretrial detention is fundamentally limited by the Sixth Amendment right to a speedy trial, which guarantees that “In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial.”7Legal Information Institute. Sixth Amendment | U.S. Constitution This right aims to prevent oppressive incarceration, minimize the accused’s anxiety, and protect their ability to mount a defense. It attaches upon arrest or formal charging.8Legal Information Institute. When the Right to a Speedy Trial Applies | U.S. Constitution Annotated
To enforce this, governments have enacted specific laws. The federal Speedy Trial Act of 1974, for instance, sets deadlines for federal cases.9United States Department of Justice. Justice Manual | 628. Speedy Trial Act of 1974 Generally, an indictment must be filed within 30 days of arrest, and the trial must begin within 70 days of the indictment or the defendant’s first court appearance, whichever is later. This 70-day clock can be paused for “excludable delays,” such as time taken for pretrial motions or competency evaluations.
Failure to meet these deadlines, accounting for allowable delays, can lead to dismissal of the charges if requested by the defendant. The court decides if the dismissal is “with prejudice” (charges cannot be refiled) or “without prejudice” (charges can be refiled), considering factors like the offense’s seriousness and the reasons for the delay.
Even without specific statutes, the Sixth Amendment itself protects against unreasonable delays. The Supreme Court’s Barker v. Wingo (1972) test balances four factors: the length of the delay, the reason for it, whether the defendant asserted their right, and the prejudice caused by the delay (including prolonged incarceration or impaired defense). A violation of this constitutional right requires dismissal of the charges with prejudice, serving as a crucial backstop against indefinite detention.
Extended Detention Due to Additional Charges
An individual already jailed pending trial might face longer detention if prosecutors bring additional charges. This can happen through new cases or, more commonly, by amending the existing case with a superseding indictment or information.
New charges, especially serious ones, often prompt a review of the person’s custody status. A court might revoke previously granted bail or increase the amount based on the expanded charges or heightened perceived risks. If the new charges qualify for pretrial detention under laws where the original ones did not, or create a presumption favoring detention, the individual may be held even if they might have been released otherwise.
Adding charges can also complicate the case procedurally, leading to delays that extend pretrial custody. Defending against more numerous or complex allegations may require more time for investigation and legal motions. While potentially reasonable, these delays contribute to a longer period before trial or plea, thereby prolonging incarceration without conviction.
Consequences of Prolonged Pretrial Detention
Extended time in jail before conviction has severe personal and societal costs. Even short stays can destabilize lives, increasing the risk of job loss and homelessness. Lost income harms families, potentially leading to poverty and difficulty meeting basic needs.
Pretrial incarceration can also harm physical and mental health. Jails may lack adequate healthcare, and the stress and isolation of confinement can worsen existing conditions or create new ones. Studies indicate higher rates of psychological distress and self-harm among pretrial detainees compared to convicted prisoners.10Vera Institute of Justice. Justice Denied: The Harmful and Lasting Effects of Pretrial Detention
The length of pretrial detention appears linked to case outcomes. Research suggests that detained individuals are more likely to plead guilty, potentially feeling pressured to accept deals simply to gain release, regardless of actual guilt. Studies have found detained defendants are more likely to be convicted and receive sentences involving incarceration compared to similar defendants released pretrial.11Yale Law School via Indiana Public Defender Council.

Prolonged detention may also contribute to future involvement with the justice system. Some research suggests time spent in jail pretrial can have a criminogenic effect, increasing the likelihood of future arrests. Studies indicate that individuals detained pretrial, especially those initially assessed as low-risk, had higher rates of new arrests compared to similar individuals released soon after arrest.12University of Pennsylvania Law School.
