Civil and criminal law are two distinct legal systems operating side-by-side in courtrooms. Whether you are watching a courtroom drama, reading the news, or facing a legal issue yourself, knowing the difference between these two types of law is vital to understanding how our legal system works. By the end of this blog, you will better understand what makes civil and criminal law different and learn how these systems might impact you.

The Key Differences Between Civil and Criminal Law 

Understanding the distinctions between these two systems is essential for anyone navigating the legal system.  

What is Criminal Law? 

In the United States, criminal law is primarily defined by statutes passed by a state or federal legislature. The statute is a law that will explicitly mention incarceration (jail or prison), probation and/or fines, if violated. To put it simply, if a law empowers the state to take away your liberty, it is probably a criminal law. It may also impose a "fine," but in criminal law, that fine is paid to the government as a punishment, not to a victim as compensation. The reason for this punitive power is that when someone violates certain types of statutes, they're not just harming an individual, they're violating laws designed to protect everyone within society. Hence, the government prosecutes the accused offenses on behalf of the "people.”  

What is Civil Law? 

Civil law aims to make the injured party whole and resolve disputes between individuals, businesses, or organizations. Civil law creates pathways for individuals to resolve disputes and seek compensation when they've been wronged, ensuring that disputes can be resolved fairly without requiring government prosecution (though the government can also use civil law as a coercive tool—see below). In theory, by allowing individuals to channel their disputes through the courts, the civil justice system provides a controlled mechanism of dispute resolution that prevents the dispute from spreading and creating new harms for the broader public. However, in an over-active civil justice system where lawsuits become too frequent and damages too unpredictable, the costs of those private disputes can show up as higher insurance premiums, higher prices, or fewer services for communities, states, and the country at large.  

Public Law or Private Law 

Beyond private law actions brought by private parties, certain civil actions can be brought by the government through what is known as public law. Private law actions are initiated on behalf of harmed individuals, businesses, or organizations who can obtain monetary or other redress for their injuries. In contrast, public law actions are initiated by the government and typically involve civil fines or injunctions to protect the public interest. 

For instance, the Federal Trade Commission (FTC) can bring civil enforcement actions against companies that it accuses of engaging in deceptive advertising or unfair business practices. These actions seek to stop harmful conduct and may result in fines paid to the government, rather than compensation to individual victims. Similarly, the Environmental Protection Agency (EPA) can file civil lawsuits against companies that violate environmental regulations, seeking penalties and requiring compliance with the law.  

Parties Involved 

In civil cases, the dispute can be between private parties or the government (public law actions), and the injured party initiates the action seeking compensation or other remedies.  

In criminal cases, the state or government prosecutes the accused on behalf of society, as crimes are considered offenses against the public. 

Burden of Proof 

The burden of proof differs significantly between civil and criminal cases.  

In civil cases, the plaintiff must typically prove their case by a "preponderance of the evidence," meaning they must tip the scales slightly in their favor by showing that the evidence more likely than not supports their claims. This relatively low standard reflects society's interest in resolving disputes efficiently and equitably, as the consequences of an erroneous judgment typically involve monetary remedies rather than loss of liberty. 

In criminal cases, the prosecution must establish the defendant's guilt "beyond a reasonable doubt," a much higher standard that is meant to make an erroneous judgment very unlikely. Because a person’s freedom is at stake, and because American culture and law place a very high value on individual rights and liberties, this standard is intentionally difficult for the government to meet. If there is even a small logical doubt, the jury must acquit. While there is no specific percentage defined in the law, you can think of this as needing somewhere between 85% and 100% certainty. 

Examples of criminal cases: 

• Burglary and theft: A person breaks into a home at night and steals jewelry valued at $5,000. The local district attorney's office prosecutes the case on behalf of the state, seeking criminal penalties. If convicted of burglary and theft, the defendant could face prison or jail time, be ordered to pay fines to the government, and be placed on probation. 

• Aggravated assault: During an argument outside a bar, one person punches another with brass knuckles, causing a broken jaw and severe facial injuries requiring surgery. The state brings criminal charges because the attack threatens public safety. The prosecution must prove beyond a reasonable doubt that the defendant intentionally or recklessly caused serious injury with extreme indifference to human life, and if convicted of aggravated assault, the defendant could be sentenced to jail or prison and required to complete other activities designed to prevent them from committing the same offence again, such as anger management programs. 

• Drug trafficking: Police discover an individual selling fentanyl near an elementary school. Federal prosecutors charge the person because the crime threatens public safety and violates federal law. Because the offense occurred in a school zone, the government seeks a lengthy prison sentence to punish the offender and deter others from similar conduct for drug trafficking in a school zone. 

Examples of civil cases: 

• Medical malpractice: A patient undergoes what is supposed to be a routine surgery. During the procedure, the surgeon fails to notice a piece of surgical equipment left inside the patient, causing serious internal bleeding and complications that require additional surgeries and months of recovery. The patient files a civil lawsuit against the doctor, the hospital, and/or other parties that they claim were involved in the incident, claiming medical malpractice, seeking compensation for medical bills, lost income and the long‑term impact on daily life. If the patient proves by a preponderance of the evidence that the doctor failed to meet the standard of care and that this failure caused the harm, the court may award money damages. 

• Car accidents: A driver runs a red light while texting and crashes into another vehicle, causing the other driver to suffer a herniated disc requiring surgery and six months of physical therapy. The injured driver files a civil lawsuit seeking compensation for $150,000 in medical bills, $40,000 in lost wages, and damages for ongoing pain. If the plaintiff proves by a preponderance of the evidence that the defendant was negligent, the court may award monetary damages for negligence. 

• Breach of contract: A homeowner hires a contractor to renovate their kitchen for $30,000, providing a 50% deposit upfront, but the contractor abandons the project after only demolishing the old cabinets. The homeowner sues to recover the $15,000 deposit and an additional $20,000 needed to hire another contractor to complete the work. The civil court can order the defendant to pay damages for breach of contract. 

Constitutional Protections 

Criminal defendants receive extensive constitutional safeguards due to the potential loss of liberty or life, including the presumption of innocence, the right to remain silent, the right to legal counsel (even if they cannot afford one), and protection against being tried twice for the same offense, known as double jeopardy. 

Civil litigants, while still governed by procedural rules, do not receive the same level of constitutional protections, as the stakes typically involve monetary or equitable remedies rather than personal freedom. However, some constitutional provisions include civil protection. If you break a civil statute, the result is usually that you must pay money to the person or entity you hurt to "make them whole," or you are ordered by a court to stop doing something (an injunction). A person cannot be sent to jail for violating a civil statute—though refusing to comply with court orders can sometimes lead to incarceration for contempt. 

Can a Case Be Both Civil and Criminal? 

Have you ever wondered why someone can be found "not guilty" in criminal court but still lose a civil lawsuit over the same incident? While civil and criminal law are distinct systems, certain conduct may give rise to both civil and criminal liability. The proceedings remain separate, with different burdens of proof and objectives, but the same act can trigger both. 

For instance, an act of assault may result in criminal prosecution by the state, seeking to punish the offender and deter future crimes. Meanwhile, the victim of the assault can bring a civil lawsuit against the person who assaulted them and/or other people or entities that the victim alleges bear some responsibility for the incident, seeking monetary compensation for medical bills, lost wages, and pain and suffering. The outcomes can differ. A defendant might be acquitted in criminal court (where the standard is "beyond a reasonable doubt") but still be found liable in civil court (where the standard is "preponderance of the evidence"). This happened in the infamous O.J. Simpson case, where Simpson was acquitted of criminal charges but later found liable in a civil case. 

Why Understanding the Difference Matters 

Both civil and criminal law serve essential but different purposes in our legal system. Criminal law protects society by punishing offenses against the public, while civil law resolves disputes between private parties and compensates those who have been wronged.  

When civil law works well, it fairly compensates people who are genuinely harmed and encourages safer behavior. However, all too often, the civil justice system delivers paydays for lawyers while leaving those harmed with little or no compensation, or allows “frivolous” lawsuits without a strong basis in fact to pressure defendants into settling. As this type of litigation grows more frequent, and as jury verdicts grow larger and less predictable, the costs can ripple outward in the form of higher prices, higher insurance premiums and fewer choices for consumers.  

Knowing the difference between civil and criminal law isn’t just for lawyers or judges. These systems shape the world you live in, and the better you understand them, the better equipped you will be to understand your rights and support important changes to how the law works.
