Legal Minimum Marriage Age & Child-Marriage Law in Nepal

The legal age for marriage in Nepal is 20 years for both women and men. This single, gender-neutral threshold is set by Section 70 of the National Civil Code Act, 2074 (Muluki Civil Code, 2017 AD), which lists the conditions that must be met for a valid marriage. A person must have completed 20 years of age at the time of marriage; there is no separate, lower age for either sex and no distinction between arranged and love marriages.

Crucially, there are no exceptions to this rule. The age of 20 cannot be reduced by cultural tradition, religious custom, family agreement, or the fact that a couple is already living together. Parental or guardian consent does not make a younger marriage lawful either: a marriage of a person under 20 remains illegal even if both families and both parties fully agree to it.

This is a stricter standard than in many neighbouring countries. When the Civil Code came into force it confirmed 20 as the minimum for both genders, closing earlier loopholes that had allowed marriage at 18 with parental consent. In practice, the law treats anyone marrying below 20 as entering a child marriage, regardless of how the ceremony is described.

Two 2074 (2017 AD) statutes together govern marriage age in Nepal. The National Civil Code Act, 2074 (Muluki Dewani Samhita) sets out who may marry and when a marriage is valid or void. The National Criminal Code Act, 2074 (Muluki Aparadh Samhita) defines child marriage as an offence and prescribes the punishment. Both codes were authenticated on 16 October 2017 and came into force nationwide on 17 August 2018 (1 Bhadra 2075 BS), replacing the century-old Muluki Ain.

Under Section 70 of the Civil Code, a valid marriage requires four things: both parties must give free and voluntary consent; both must have completed 20 years of age; both must be unmarried (or lawfully divorced or widowed); and the two must not fall within the prohibited degrees of kinship (the incest bar). Failing the age condition is enough, on its own, to make the marriage legally defective.

The Civil Code frames the age rule as a positive condition for validity, while the Criminal Code frames the same conduct as a punishable offence. This dual structure means an underage marriage is simultaneously void in civil law and a crime in criminal law, and the two consequences operate independently of each other.

No. Child marriage is not legal in Nepal and is never recognised as a valid marriage. Under Section 72 of the Civil Code 2074, a marriage is void if a party is below the age of 20 at the time of marriage. It is also void if either party did not consent, if the parties are within the prohibited degrees of relationship, or if one party already has a subsisting marriage.

A void marriage is treated as if it never legally existed. It is invalid from the very beginning (void ab initio), and no court order is strictly required to establish that it never had legal effect, although a party may seek a declaration to remove doubt. Because the marriage is void, it does not create the ordinary legal status of husband and wife.

This distinguishes a void marriage from a merely voidable one. A voidable marriage is valid until one party asks a court to annul it, whereas an underage marriage falls into the void category and is defective by law itself. The invalidity protects the underage person and reinforces that consent by parents or the couple cannot cure the defect.

Child marriage is a criminal offence under Section 173 of the National Criminal Code 2074. It prohibits concluding, or causing to be concluded, a marriage unless both parties have attained 20 years of age, and declares any such marriage void. A person who commits the offence of child marriage is liable to imprisonment for a term not exceeding three years and a fine not exceeding NPR 30,000.

The offence is deliberately broad in who it captures. Liability is not limited to the two people getting married: it can extend to those who arrange, conduct or facilitate the marriage. In practice this means parents and guardians who marry off a child, matchmakers, and the priest or officiant who solemnises the ceremony can all be prosecuted for their role, in addition to any adult spouse.

The three-year, NPR 30,000 ceiling is a maximum, so courts set the actual sentence and fine according to the facts of each case, including the ages of the parties and the role each accused person played. Because the punishment can be imprisonment and/or a fine, an offender may face a jail term, a monetary penalty, or both.

Marriage in Nepal is registered at the ward office of the local level (municipality or rural municipality) under the civil registration system, and age is checked at this point. The primary document used to confirm age is the Nepali citizenship certificate of each party, which records the date of birth and is normally issued only from age 16. Registrars use it to confirm that both parties have reached 20.

Where a citizenship certificate is unclear, missing, or disputed, supporting proof of age such as a birth registration certificate or a school leaving certificate can be presented. Applicants also submit an application form, passport-size photographs, and the details of witnesses. Because the registrar is verifying a legal condition of the marriage, an application showing an under-age party should not be registered.

This registration check is a practical safeguard, but it is not the only test of validity. A marriage entered below 20 is void whether or not it was ever registered; conversely, registration does not cure an underage marriage. The documentary verification simply helps prevent unlawful marriages from being recorded and gives authorities a paper trail if the age rule is breached.

Although the law is strict, child marriage remains a significant social problem, especially in rural and less-educated communities. According to UNICEF and national survey data, roughly a third of young Nepali women aged 20 to 24 report having married before the age of 18, a figure that has fallen substantially from earlier decades but is still high by global standards. Nepal is also notable internationally for a comparatively high rate of child grooms, with more than one in ten boys married before 18.

Prevalence varies sharply with education and location. Child marriage is far more common among girls with no schooling than among those with secondary education, and somewhat more common in rural than urban areas. Poverty, social norms, dowry expectations, and limited access to education and reproductive health services are widely cited drivers.

The Government of Nepal, through the Ministry of Women, Children and Senior Citizens, has adopted a national strategy to end child marriage, working alongside UN agencies such as UNFPA and UNICEF and civil-society organisations. Policy briefs on ending impunity for child marriage stress that enforcement of the 20-year age rule, birth and marriage registration, and girls' education are central to closing the gap between the law on paper and reality.
