Adultery And The Law: Is Cheating Illegal?

Adultery laws vary across the world, with some countries and states imposing harsh punishments, including fines, imprisonment, and even capital punishment. In the United States, adultery is illegal in several states, though enforcement varies and prosecutions are rare. While adultery may not always be a criminal offense, it can have significant legal consequences, particularly during divorce proceedings, where it can impact spousal support, property division, and child custody arrangements.

Adultery laws in the US

Adultery laws refer to legal provisions that deal with extramarital sex. Historically, adultery was considered a serious crime in many cultures, sometimes even subject to severe punishment, including capital punishment, mutilation, or torture. While such punishments have fallen out of favour in Western countries since the 19th century, adultery remains a criminal offence in several countries, particularly those with a dominant Islamic religion.

In the United States, adultery laws vary from state to state. Adultery is considered a crime in 16 states and Puerto Rico, although prosecutions are rare. Three states, including Oklahoma, Michigan, and Wisconsin, classify adultery as a felony, while 13 states and Puerto Rico classify it as a misdemeanour. The punishments for adultery range from small fines to significant jail time and substantial fines. For example, in Wisconsin, adultery can result in a fine of up to $10,000 and up to three and a half years in prison. In contrast, Maryland imposes only a $10 fine for adultery.

While adultery laws are rarely enforced in the United States, they can have legal consequences, especially in divorce proceedings. Adultery can be a ground for divorce in fault-based jurisdictions and may impact property settlements, child custody, and alimony. However, in no-fault divorce jurisdictions, adultery is not a ground for divorce but may still be considered in child custody and property disputes.

There have been recent efforts to repeal adultery laws in certain states, such as New York, where legislators are considering repealing a 1907 state law that classifies adultery as a misdemeanour. These efforts align with the trend of decriminalising adultery in Western countries since the 20th century.

Adultery laws in Muslim countries

Adultery is considered a sin in almost all religions. Under Muslim law, adultery is defined as sexual intercourse by a person, whether man or woman, with someone to whom they are not married. Adultery or extramarital sex is considered an infringement of the matrimonial bond and is regarded as one of the foremost crimes condemned by Allah in the Quran, the religious book of Muslims.

Zina is an Arabic term used for premarital or extramarital relationships. The act of zina is considered a heinous crime and people may be punished harshly for it. According to Islamic laws, the punishment for premarital sex is 100 lashes, while for adultery, the adulterers are punished by stoning to death, also known as Rajm, or severe flogging. However, stoning as punishment for extramarital sex is not stated in the Quran but is prescribed in the Hadith, which are the verbal traditions connecting to the words and conduct of the Islamic prophet Mohammed.

In Muslim countries that follow Sharia law for criminal justice, the punishment for adultery may be stoning. There are fifteen countries in which stoning is authorized as lawful punishment, though in recent times it has been legally carried out only in Iran and Somalia. Countries that follow very strict versions of Sharia law in their criminal systems include Saudi Arabia, Iran, Brunei, Afghanistan, Sudan, Pakistan, 12 of Nigeria's 36 states, and Qatar; although these laws are not necessarily enforced.

In some jurisdictions, the "intruder" (the third party) is punished instead of the adulterous spouse. For instance, under the adultery law in India until 2018, it was a criminal offense for a man to have consensual sexual intercourse with a married woman, without the consent of her husband. No party was criminally punished in the case of adultery between a married man and an unmarried woman.

Adultery and divorce

In the context of divorce, adultery can impact alimony, property division, and child custody arrangements. If your financial stability has suffered due to your spouse's adultery, it can be cited as marital misconduct and may result in higher alimony payments or a more favourable property settlement. However, adultery must generally have a clear financial impact to be considered during these proceedings. Emotional trauma resulting from adultery has also been considered in previous divorce cases.

Additionally, adultery can be challenging to prove in court. The burden of proof falls on the accuser, who must demonstrate both the opportunity for infidelity and the inclination of the adulterous spouse. This can include evidence such as love letters, text messages, or witness testimonies. Hiring a private investigator or obtaining digital evidence may be necessary but can be costly and invasive.

It is worth noting that the impact of adultery on divorce proceedings may differ depending on the specific state and its laws. For example, in no-fault divorce states like California, the courts do not consider spousal misconduct when dividing property or awarding alimony. On the other hand, in states with fault-based divorce laws, adultery can be a ground for divorce and may carry more weight in property settlements and child custody disputes.

In summary, while adultery may not always lead to criminal consequences, it can have significant financial and emotional implications for those going through a divorce. The legal landscape surrounding adultery and divorce is evolving, and it is essential to consult a family attorney to understand your specific situation and rights.

Adultery and criminal punishment

Adultery, or extramarital sex, has been considered a serious crime in many cultures throughout history, with some jurisdictions imposing severe punishments, including capital punishment, mutilation, or torture. However, in recent centuries, particularly in Western countries, these punishments have fallen out of favour, and most Western nations have decriminalised adultery.

In the United States, adultery laws vary from state to state. While it is considered a crime in 16 states and Puerto Rico, prosecutions are rare. Three states classify adultery as a felony (Oklahoma, Michigan, and Wisconsin), while 13 states and Puerto Rico classify it as a misdemeanour. The punishments for adultery in these states range from small fines to several years of imprisonment. For example, in Florida, adultery is classified as a second-degree misdemeanour punishable by up to 60 days in jail and a $500 fine. On the other hand, in Wisconsin, adultery can result in a fine of up to $10,000 and up to three and a half years in prison. Despite these laws, adultery is rarely prosecuted in the United States due to factors such as privacy concerns and the difficulty of proof.

In other parts of the world, such as Muslim-majority countries following Sharia law, adultery may be punished by stoning. South Sudan and India (until 2018) are examples of jurisdictions where the "intruder" or third party in an adulterous relationship is punished rather than the spouse. In China, adultery was once punished by differentiating sentences based on the gender of the spouse; however, it is no longer a crime.

International organisations, including the United Nations, have called for the decriminalisation of adultery, particularly in light of high-profile stoning cases. They argue that classifying adultery as a criminal offence violates women's human rights and contributes to violence and discrimination against women.

Adultery and civil lawsuits

Adultery laws vary across the world. In some countries, adultery is criminalized and can carry punishments ranging from fines to imprisonment and even capital punishment. In other countries, adultery is not a criminal offence but may still have legal consequences, particularly in divorce proceedings.

In the United States, adultery laws differ from state to state. As of 22 November 2024, adultery remains a crime in 16 states and Puerto Rico, but prosecutions are rare. These states include Alabama, Arizona, Florida, Georgia, Illinois, Kansas, Michigan, Mississippi, North Carolina, Oklahoma, South Carolina, and Wisconsin. However, the majority of U.S. states have abolished adultery laws to give people more freedom, especially with the increase in open and polyamorous relationships.

While adultery itself may not be a crime in many states, it can have legal implications in civil lawsuits. In a few states, individuals can file civil tort claims, such as "criminal conversation" or "alienation of affection," against a third party who interfered with their marriage. To prove criminal conversation, one must demonstrate a valid marriage, that the spouse and the defendant engaged in a sexual act during the marriage, and that the act occurred within the state's statute of limitations. For alienation of affection, one must show a valid and loving marriage, that the love and affection were lost, and that the defendant's actions caused the loss of affection.

It is important to note that these types of civil lawsuits are generally uncommon and difficult to win, as courts tend to view them with disfavor. Additionally, adultery can have implications in divorce proceedings, impacting the division of assets, alimony, and child custody arrangements, depending on the state's laws.
