The Legal Age of Marriage in Bangladesh - and Why We Enforce 18+

A headmistress in a Rangpur upazila keeps a mental list every year. Four or five girls from Class Eight simply stop coming after the winter holidays. Nobody announces anything. Two months later someone mentions a wedding in a neighbouring union, and a birth certificate that said the bride was eighteen when everyone in the room knew she was fourteen.

That gap — between what the law says and what a birth certificate can be made to say — is the whole subject of this article. The legal age of marriage in Bangladesh is not ambiguous. Enforcing it is where everything breaks down.

What the law actually says

Under the Child Marriage Restraint Act 2017, a child for the purposes of marriage is a male who has not completed 21 years or a female who has not completed 18 years. The full English text published by UNICEF Bangladesh is short and worth reading once.

The Act does not only punish the person who marries a child. It reaches everyone who makes the marriage happen, which is the part families rarely understand until a case is filed.

Who commits an offence, and what it costs

• An adult who marries a child — imprisonment of up to two years, or a fine of up to Tk 1 lakh, or both.
• Parents, guardians or anyone who arranges, permits or fails to prevent the marriage — imprisonment of six months to two years, or a fine of up to Tk 50,000, or both.
• Whoever solemnises or conducts the marriage — the same range of imprisonment and fine.
• A marriage registrar who registers a child marriage — the same penalties, plus cancellation of the licence that is his livelihood.
• A minor who contracts the marriage may face detention of up to one month or a fine, although the Act makes an exception where a case is brought against the guardians instead.

Notice what is missing from that list. The Act punishes people; it does not automatically make the marriage disappear. A girl married at fifteen is not tidily returned to her old life by a conviction, which is precisely why prevention matters more than penalty.

Section 19, and why it is argued about

The 2017 Act contains a special provision allowing a marriage below the minimum age in prescribed special circumstances, in the best interests of the minor, with the direction of a court and the consent of parents or guardians. It was heavily criticised when the Act was passed, on the ground that a narrow exception becomes a wide door in practice.

Two things are worth being clear about. It is not a general permission, and it is not something a kazi, a matchmaker or a union chairman can grant over tea. Anyone telling a family that section 19 makes an underage marriage lawful in their case is either mistaken or selling something.

The numbers, and which way they are moving

UNICEF's country profile on child marriage in Bangladesh, drawing on the 2019 MICS survey, records that 51 per cent of women aged 20 to 24 were married before 18 and 16 per cent before 15 — the highest prevalence in South Asia.

More recent national data points the wrong way. According to Bangladesh Bureau of Statistics figures, the share of marriages taking place before 18 rose from 30.0 per cent in 2018 to 40.9 per cent in 2022. The Business Standard reported on that finding alongside the parallel rise in divorce, in a piece on what the BBS numbers say about the country's future.

A law that is well drafted and weakly enforced produces exactly this pattern: falling numbers on paper, forged birth certificates in practice, and the burden landing on girls in the poorest households.

Why 18 is not an arbitrary line

The case for waiting is not sentimental. A marriage before 18 usually ends a girl's education, which decides her earnings for the rest of her life. It brings early pregnancy, which carries higher medical risk for both mother and child. It hands a teenager the negotiation of den mohor, household finances and in-law relationships at an age when she has no standing to negotiate anything.

It also does not protect the family from the thing they usually fear most. Marriages arranged under pressure, with no real consent and no shared expectations, are the ones most likely to fail — and BBS recorded the national divorce rate doubling between 2021 and 2022. Marrying a daughter early is not a way of securing her future. It is a way of transferring the risk to her.

What families say, and what is worth saying back

• The proposal is very good and it will not come again. A good proposal for a fourteen-year-old is still a criminal offence, and a family that would insist on it is telling you something about how they will treat her later.
• She will be safer married. Safety comes from schooling, income and a family who will take her back, not from a household she has no power in.
• Everyone does it here. Prevalence is not permission, and the registrar, the guardians and the person conducting the marriage are all exposed.
• We can adjust the birth certificate. That is a separate offence layered on the first one, and it follows the girl through every NID, passport and inheritance question for the rest of her life.

If the pressure in your own house is the ordinary kind — a family that thinks twenty-four is late — the conversation is different, and Telling Your Parents You Are Ready for Marriage may be more useful than any statute.

Where amarjibon stands

amarjibon does not carry underage profiles, and this is not a policy we intend to be flexible about. Every profile is verified against a National ID with a liveness selfie check, so age is established from a government document rather than from a self-declared date of birth. A profile that cannot clear that check does not appear in search, and accounts that misrepresent age are removed.

We also refuse to treat dowry as a normal part of a marriage negotiation, for the same reason — both practices push the youngest and poorest girls into the worst marriages. What is actually illegal is set out in The Dowry Prohibition Act 2018, and once a marriage is agreed, Marriage Registration in Bangladesh explains why the registrar checks age before anything is signed.

If you know of a child marriage being planned, the national helpline 109 and the local upazila administration both act on this, and they act faster than most people expect.

Marriage taken seriously means marrying adults

On amarjibon, every profile is NID-verified with a liveness selfie check, families can be part of the conversation from the first message, and you can filter on the things that decide compatibility — observance, education, district of origin, and expectations about work and household. It is bilingual in English and বাংলা, and your phone number stays private until you choose to share it.
