A criminal conviction is a court’s formal judgment that you are guilty of a crime. It can be entered after a jury or judge finds you guilty at trial, or after you plead guilty or no contest, but in every form it requires — or rests on an admission that satisfies — proof beyond a reasonable doubt.1Constitution Annotated. Amdt14.S1.5.5.5 Guilt Beyond a Reasonable Doubt Once a conviction is on your record, it opens the door to a sentence and to a long list of other legal consequences that often outlast the sentence itself.
Most convictions never involve a trial. Roughly 98 percent of federal cases and 95 percent of state cases are resolved through plea agreements, which means the typical conviction is the product of a negotiated plea, not a jury verdict.
The Proof Standard Behind Every Conviction
The Constitution requires the government to prove every element of a criminal charge beyond a reasonable doubt. The Supreme Court established this as a due process requirement in In re Winship (1970), describing the standard as “a prime instrument for reducing the risk of convictions resting on factual error.”1Constitution Annotated. Amdt14.S1.5.5.5 Guilt Beyond a Reasonable Doubt It sits well above the “preponderance of the evidence” standard in civil cases, where a plaintiff only has to show something is more likely true than not.
How a Conviction Is Entered
Guilty Pleas
When you plead guilty, you admit in open court that you committed the crime and give up your right to a trial.2United States Department of Justice. Plea Bargaining Before a judge can accept the plea, the judge must personally confirm that you understand the charges, the rights you are waiving (including the right to a jury, the right to confront witnesses, and the protection against self-incrimination), and the maximum possible penalties.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 11 – Pleas Most guilty pleas come out of plea bargaining: you agree to plead, often to a reduced charge, in exchange for a lighter recommended sentence or the dismissal of other counts. The judge is not bound by the deal but usually follows it, and the case moves directly to sentencing.
No-Contest and Alford Pleas
A no-contest plea (nolo contendere) produces a conviction and the same penalties as a guilty plea. The difference is that it cannot be used against you as an admission of guilt in a later civil lawsuit, which matters when the same incident could also lead to a personal injury claim.
An Alford plea goes further. Under the Supreme Court’s decision in North Carolina v. Alford, you can accept a conviction and a sentence while continuing to maintain that you did not commit the crime, as long as the plea is voluntary and informed and the record contains strong evidence of guilt.4Legal Information Institute. North Carolina v. Alford The resulting conviction carries the same legal weight as any other.
Trial Verdicts
At a jury trial, twelve jurors hear the evidence and must reach a unanimous guilty verdict to convict. The Supreme Court confirmed in Ramos v. Louisiana (2020) that the Sixth Amendment requires unanimity for serious criminal offenses in both federal and state courts.5Supreme Court of the United States. Ramos v. Louisiana One holdout produces a hung jury rather than a conviction, and the prosecution then decides whether to retry. In a bench trial, the judge alone weighs the evidence and decides guilt. The same beyond-a-reasonable-doubt standard applies either way.
What Does Not Count as a Conviction
Several points in the criminal process look like convictions but are not. Confusing them can cost you — on job applications, firearms purchases, and immigration forms where “have you been convicted” is a legally loaded question.
- An arrest is a police action based on probable cause. No guilt is determined.
- Charges are a prosecutor’s formal accusation. They mean the government believes it has enough evidence to proceed, not that you are guilty.
- An indictment is a grand jury’s finding that enough evidence exists to bring you to trial. Grand juries hear only the prosecution’s side and apply a low evidentiary standard.
- An acquittal is a finding of not guilty — the opposite of a conviction. Double jeopardy generally prevents the government from retrying you on the same charges.
Diversion and Deferred Adjudication
Some defendants avoid a conviction altogether through diversion or deferred adjudication, even after charges are filed. In a pretrial diversion program, the prosecution pauses the case while you complete conditions such as community service, drug treatment, or a supervision period. Finish successfully and the charges are dismissed with no conviction entered. Fail and prosecution resumes.
Federal law provides a specific version for first-time simple drug possession. Under 18 U.S.C. § 3607, a court can place you on probation for up to one year without entering a judgment of conviction, and completion without a violation leads to dismissal. The statute states that this outcome “shall not be considered a conviction” for any purpose, and defendants under 21 can apply to have the record expunged.6Office of the Law Revision Counsel. 18 U.S. Code 3607 – Special Probation and Expungement Procedures for Drug Possessors
Deferred adjudication is slightly different. The judge accepts your guilty plea but withholds the formal finding of guilt while you serve a probation-like period. Finish the conditions and no conviction is entered.
The Immigration Exception
If you are not a U.S. citizen, that favorable state-law outcome may not help you. Federal immigration law defines “conviction” more broadly than criminal law does. Under 8 U.S.C. § 1101(a)(48)(A), you have a conviction for immigration purposes if a judge or jury found you guilty — or you pleaded guilty or no contest — and the judge ordered any form of punishment or restraint on your liberty, even if the court officially withheld a judgment of guilt.7Office of the Law Revision Counsel. 8 USC 1101 – Definitions A deferred adjudication that counts as “no conviction” at the state courthouse can still trigger deportation. Any non-citizen weighing a plea should talk to an immigration attorney before signing anything.
Felonies, Misdemeanors, and Infractions
How serious a conviction is depends almost entirely on how the offense is classified. Under federal law, a felony is any crime punishable by more than one year of imprisonment, and a misdemeanor carries one year or less.8Office of the Law Revision Counsel. 18 U.S. Code 3559 – Sentencing Classification of Offenses Below misdemeanors sit infractions, which carry no jail time or at most a few days. Most states use a similar structure, with their own penalty ranges and labels.
The felony line matters because it drives most of the downstream consequences. A felony conviction can take away the right to own a firearm, serve on a jury, and in many states vote. A misdemeanor conviction leaves most of those rights intact but still creates a criminal record that appears on background checks.
Sentencing
Once the court enters a conviction, the case moves to sentencing. Minor offenses are sometimes sentenced on the spot. For felonies, the judge usually schedules a separate hearing weeks or months later to allow a pre-sentence investigation covering your criminal history, personal circumstances, employment, and health.
Judges work within ranges set by statute and are guided by sentencing guidelines, with the amount of discretion varying by jurisdiction. Common sentences include incarceration, probation, fines, and community service. For certain federal offenses — crimes of violence, property offenses, fraud, and consumer tampering — the judge must order restitution to compensate identifiable victims for their losses.9Office of the Law Revision Counsel. 18 U.S. Code 3663A – Mandatory Restitution to Victims of Certain Crimes Restitution is separate from any fines paid to the government and goes to the people harmed.
Aggravating factors (such as using a weapon, targeting a vulnerable victim, or prior convictions) push the sentence toward the top of the statutory range. Mitigating factors (minimal criminal history, cooperation with authorities, evidence of rehabilitation) pull it lower.
Collateral Consequences
The sentence imposed in court is only one part of what a conviction costs. A set of automatic legal consequences follows the conviction itself, and they rarely get mentioned at the hearing.
Firearms
Federal law makes it illegal for anyone convicted of a crime punishable by more than one year in prison to possess a firearm or ammunition, regardless of whether you actually served prison time. A separate provision extends the ban to anyone convicted of a misdemeanor crime of domestic violence.10Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Violating the ban is itself a federal felony.
Voting
A felony conviction affects voting rights in nearly every state, but the rules vary. A few states never take voting rights away. Most restore them automatically on release from prison or after completion of the full sentence including parole and probation. A handful can bar voting indefinitely for certain serious offenses. Restoration sometimes requires a formal application.
Jury Service
Federal law disqualifies you from serving on a federal jury if you have been convicted of a crime punishable by more than one year in prison and your civil rights have not been restored.11Office of the Law Revision Counsel. 28 U.S. Code 1865 – Qualifications for Jury Service Most states have similar rules for state juries, and the disqualification is permanent absent a pardon or expungement.
Immigration
For non-citizens, a conviction can mean deportation. Federal law makes any non-citizen deportable if convicted of an “aggravated felony” at any time after admission. Convictions for crimes involving “moral turpitude” can also trigger removal — particularly if the crime occurred within five years of admission and carries a possible sentence of a year or more, or if the person has two or more such convictions.12Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens The immigration term “aggravated felony” is broader than it sounds and reaches offenses that would be misdemeanors under many state codes.
Employment
A conviction can block jobs. Under Title VII of the Civil Rights Act, employers cannot use blanket policies to reject every applicant with a criminal record if the policy disproportionately excludes people based on race or national origin. EEOC enforcement guidance requires any criminal-record screening policy to be “job related and consistent with business necessity,” taking into account the nature of the crime, how much time has passed, and the nature of the job.13U.S. Equal Employment Opportunity Commission. Enforcement Guidance on the Consideration of Arrest and Conviction Records in Employment Decisions Separately, many licensed professions — law, medicine, nursing, finance, education — require disclosure of convictions on license applications, and a serious conviction can lead to denial or revocation.
Housing
Landlords commonly run criminal background checks, and federal guidance warns that blanket bans on renting to anyone with a record may violate the Fair Housing Act when the policy has a discriminatory impact. Even so, a conviction showing up on a background check still makes securing housing significantly harder in practice.
Undoing a Conviction
A conviction is not necessarily permanent. Three paths exist, and none is simple.
Expungement and Record Sealing
Expungement erases a conviction from your criminal record. Record sealing hides it from public view while keeping it accessible to law enforcement and certain government agencies. Eligibility rules, waiting periods, and qualifying offenses vary dramatically by state; waiting periods for misdemeanors alone range from immediate eligibility to ten years after sentence completion. Court filing fees vary by jurisdiction, and many states offer waivers for low-income petitioners. A successful expungement does not guarantee invisibility, because old records sometimes persist in private background-check databases.
Pardons
A presidential pardon (federal) or a governor’s pardon (state) forgives the crime and restores civil rights such as voting and jury service. A pardon is an act of executive clemency, not a judicial finding of innocence, and it does not remove the conviction from your criminal record. Both the offense and the pardon continue to appear.
Vacating a Conviction
If a conviction was obtained in violation of the Constitution, if the court lacked jurisdiction, or if the sentence exceeded what the law allows, you can ask the court to vacate it. In the federal system, 28 U.S.C. § 2255 allows a prisoner to move the sentencing court to “vacate, set aside or correct the sentence” on those grounds.14Office of the Law Revision Counsel. 28 U.S. Code 2255 – Federal Custody Remedies on Motion Attacking Sentence A successful motion can produce release, a new trial, or resentencing. These challenges are hard to win because courts require specific constitutional or jurisdictional errors rather than disagreement with the outcome, but when they succeed the conviction is treated as if it never happened.
