Understanding Polygamy Laws and Marriage Regulations in Nepal Today

Marriage is a fundamental social institution that binds individuals into a union recognized both culturally and legally. It provides the foundation for family life, shaping social norms, values, and interpersonal relations. While marriage is often associated with love, emotional companionship, and shared responsibilities, its structure, customs, and legal rules differ widely across societies.

In Nepal, polygamy, marrying more than one spouse at a time, has historical and cultural roots. It was traditionally practiced among particular ethnic groups, in rural communities, and within aristocratic families. Influenced by religious beliefs, social hierarchy, and economic conditions, polygamy once functioned as an accepted custom. However, with legal modernization and the growing influence of international human rights principles, Nepal has gradually moved toward eliminating this practice.

Today, Nepalese law formally upholds monogamy as the legal norm. The Muluki Civil Code clearly forbids polygamous unions, making second marriages illegal while a previous marital relationship continues. Despite these legal restrictions, polygamy still persists in some areas due to long-standing traditions, financial dependency, and weak enforcement mechanisms. Consequently, debates continue regarding how to preserve cultural identity while ensuring gender equality and legal accountability.

Under the Muluki Civil Code, 2074, Section 70(c) explicitly requires that a marriage can only take place if neither partner is already legally married. This reflects the influence of Hindu family traditions, which emphasize loyalty and exclusivity in marital relationships. Engaging in a second marriage while the first is still valid is not only socially condemned but also unlawful in Nepal.

Additionally, Section 71(2e) states that a marriage cannot be concluded by concealing or falsely representing one’s marital status. Section 71(3) further provides a remedy for the victim of such deceit: the aggrieved party has the right to have the marriage declared void and seek reasonable compensation from the person who misrepresented their status. These provisions aim to protect individuals, particularly women, from deception and exploitation.

Bigamy or polygamy is further addressed under the Muluki Penal Code, 2074, Section 175, which imposes criminal liability on offenders. The law states:

• A married man cannot marry another woman during the subsistence of the first marriage.
• A woman is also prohibited from entering into marriage with a man who she knows is already married.
• An exception exists only if the spouses have legally separated after partition of property.
• Violation of this law results in imprisonment ranging from one to five years and a fine between ten thousand and fifty thousand rupees.
• Any such marriage becomes automatically void by law.
• The complaint must be filed within three months from the date when the aggrieved party becomes aware of the offense.

These punishments are designed to safeguard marital commitments, prevent domestic disputes, and uphold the legal rights of spouses, especially women, who are often the ones negatively affected in polygamous situations.

Regarding legal procedures, polygamy is categorized as a state-party offense according to Schedule 1(1)(a)(10) of the National Penal Code, 2074. This means the government prosecutes the case on behalf of the victim. As per Section 4 of the National Criminal Procedure Code, 2074, the victim must first file a First Information Report (FIR) with the nearest police office. After receiving the complaint, the police conduct an investigation and prepare a case file. If the District Government Attorney finds sufficient evidence, they will register a charge sheet in the District Court before the deadline expires.

Although Nepal has established strict legal measures to abolish polygamy, the effectiveness of these policies depends heavily on enforcement and public awareness. While imprisonment and financial penalties demonstrate the government’s determination to protect monogamous marriage, legal restrictions alone may not fully change deeply rooted societal attitudes.

Therefore, continuous efforts are needed to educate communities about the harms associated with polygamy, such as emotional abuse, economic inequality, and the violation of women's rights. Strengthening legal systems, empowering women with access to justice, and promoting social reforms are essential for meaningful progress.

In summary, marriage remains an essential institution in Nepal, reflecting both cultural identity and legal principles. The nation’s laws firmly establish monogamy as the standard marital system and criminalize bigamy to ensure fairness, commitment, and equality among spouses. Nepal’s ongoing social and legal evolution aims toward a future where marriage is grounded in mutual respect, human dignity, and adherence to the law, supporting the creation of a just and gender-equal society.
