Bigamy is a legal term that refers to the act of marrying one person while still being legally married to another. It is considered a crime in many jurisdictions and can have serious legal consequences.

Definition of Bigamy:

Bigamy is a marriage-related offense that involves the act of marrying a second spouse while the individual is still legally married to their first spouse. It essentially constitutes a fraudulent or illegal second marriage because it occurs without legally dissolving the existing marital relationship.

The key elements of bigamy typically include:

Existing Marriage:  The accused person must already be in a legally recognized marriage at the time they enter into a second marriage. This existing marriage forms the basis for the bigamy charge.

Second Marriage: Bigamy occurs when an individual willfully and knowingly enters into a second marriage with another person while the first marriage remains valid and legally binding.

Knowledge of Existing Marriage:  In most jurisdictions, the accused person must have knowledge of their existing marriage. Marrying a second spouse while genuinely believing that the first marriage is legally dissolved may not meet the criteria for bigamy in some cases.

Implications and Penalties of Bigamy:

Bigamy is considered a criminal offense in many legal systems, and the penalties for committing bigamy can vary by jurisdiction. The severity of the penalties may depend on factors such as local laws, the circumstances of the case, and whether the accused person has a history of previous convictions. Common penalties and implications of bigamy may include:

Criminal Charges: The accused person may be charged with a criminal offense. Depending on the jurisdiction, bigamy may be classified as a misdemeanor or a felony.

Prison Time: A conviction for bigamy can result in imprisonment. The length of the sentence can vary widely, with more serious cases often resulting in longer prison terms.

Fines: The court may impose fines on the individual convicted of bigamy. The amount of the fine can vary and may be determined by local laws and the severity of the offense.

Invalidation of Second Marriage: In many jurisdictions, the second marriage entered into while the first marriage is still legally valid is considered void and legally invalid. This means that the rights and obligations typically associated with marriage, such as property rights and spousal support, may not be recognized.

Legal Consequences: The accused person may face a variety of legal consequences, including divorce proceedings, property disputes, and child custody issues stemming from the voided second marriage.

Criminal Record: A conviction for bigamy can result in a criminal record, which can have long-term consequences, including difficulties with employment, housing, and other aspects of life.

Moral and Social Consequences: In addition to legal consequences, bigamy can lead to significant social and moral consequences, including damage to personal relationships, reputation, and social standing.

Defenses to Bigamy Charges:

Defending against bigamy charges can be complex, and the specific defenses available may vary depending on the circumstances of the case and the applicable laws in the jurisdiction. Some potential defenses to bigamy charges may include:

Lack of Knowledge: If the accused person genuinely believed that their first marriage was legally dissolved or void, they may argue that they lacked the knowledge required for a bigamy conviction.

Duress or Coercion: If the individual was forced or coerced into entering the second marriage, they may argue that they did not willingly participate in the act of bigamy.

Void First Marriage: If the first marriage was void from the beginning due to legal reasons (e.g., the spouse was already married to someone else), the accused person may argue that they did not commit bigamy.

Marital Dissolution: If the accused person can provide evidence that their first marriage was legally dissolved through divorce or annulment before entering into the second marriage, they may have a defense against bigamy charges.

Mistaken Identity: In rare cases, an individual may be wrongly accused of bigamy due to mistaken identity or a clerical error in marriage records.

Lack of Evidence: Challenging the prosecution’s evidence and arguments is a common defense strategy in any criminal case, including bigamy.

International Perspectives on Bigamy:

Bigamy laws and penalties vary significantly from one country to another. Some countries have strict anti-bigamy laws with severe penalties, while others may have more lenient or culturally specific rules regarding marriage.

It is essential to understand the legal and cultural context of the specific jurisdiction in question when considering the implications of bigamy.


Bigamy is a legal term that refers to the act of marrying a second spouse while still being legally married to another. It is typically considered a criminal offense in many jurisdictions and can result in penalties such as imprisonment, fines, and the invalidation of the second marriage. The legal implications and penalties for bigamy can vary depending on local laws and the specific circumstances of the case. Defenses to bigamy charges may include lack of knowledge, duress, void first marriage, and more. Understanding the laws and consequences related to bigamy is essential for individuals considering marriage or facing potential legal issues related to multiple marriages.
