Minimum Age to Marry in Singapore

The minimum age to marry in Singapore is 18. That single number has two layers behind it: a hard legal floor set by statute, and a practical threshold at 21 below which you need other people’s permission. Knowing which rule applies to your age — and how the date is counted — saves couples from planning around a wedding they are not yet free to hold.

This guide covers civil marriages under the Women’s Charter and, separately, Muslim marriages under the Administration of Muslim Law Act. The two are different legal frameworks, so we take them in turn.

The short answer: 18 is the floor, 21 is free

Under the Women’s Charter, the law is blunt about the floor. A civil marriage “between persons either of whom is below 18 years of age is void unless the solemnisation of the marriage was authorised by a special marriage licence” (section 9). So 18 is the minimum marriageable age; a wedding below it has no legal effect at all unless the Minister has specially authorised it.

The three civil age bands, plus the Muslim-marriage minimum.

The 21 threshold is about permission, not validity. The Women’s Charter treats “a person who is below 21 years of age” as a minor for marriage (section 21A), and the Registrar must not issue a marriage licence for a minor’s marriage unless a consent condition is met. In plain terms: at 21 you are no longer a minor and can marry on your own decision; between 18 and 20 you can marry, but only with consent and extra steps; below 18 you generally cannot marry at all.

Marrying at 21 and above

Once both of you are 21 or older, no one else’s consent is needed on account of age. You file the Notice of Marriage and go through the standard process set out in our complete ROM registration guide. Age is simply not a hurdle at this point — 21 is the default the whole civil system is built around.

Marrying at 18, 19 or 20: consent plus a programme

Between 18 and below 21, you may marry, but the Registry is clear that you “cannot marry unless their parents or legal guardians give their consent and a Licence for the marriage has been granted.” Two things are required:

• Written consent from the appropriate parent or legal guardian (set out in the Women’s Charter’s Second Schedule).
• A Marriage Preparation Programme, where at least one party is a Singapore Citizen or Permanent Resident. It must be “conducted by an MSF-approved organisation,” completed before you submit the marriage application, with the certificate of attendance brought to your Verification of Documents and Declaration appointment. See our guide to the marriage preparation programme for who runs it.

There is an important exception. The consent requirement applies to “minors who have not previously married” (section 21A), and it does not apply to a minor who “was previously in a marriage that has been dissolved or annulled” or who is a widower or widow. So a person aged 18 to 20 who is already divorced or widowed does not need parental consent to remarry.

Below 18: only with a Special Marriage Licence

A marriage where either party is below 18 is void unless it is “authorised by a special marriage licence” granted by the Minister (sections 9 and 21). This is not a fee you pay for a faster wedding — it is a discretionary authorisation, and the process is demanding. The Registry states that “persons under 18 years old cannot marry unless their parents or legal guardians give their consent,” and on top of consent “the couple is also required to apply for a Special Marriage Licence.”

After the application, “the couple and the parents of the minor will be contacted by a staff from the agency appointed by MSF, for a social assessment of their suitability for marriage,” and both must attend the Mandatory Marriage Preparation Programme. The civil below-18 process “takes at least 4 months,” so it cannot be arranged quickly. And if it is granted, the clock is tight: under section 21, “if the marriage authorised by a special marriage licence under this section is not solemnised within one month from the date of the licence, the licence becomes void.”

How the age is counted

For a civil marriage, the Registry’s rule is simple: “Age is as at day of solemnization.” It is your age on the wedding day that decides which band you fall into, not your age when you file. So a couple where one partner turns 21 a week before the ceremony is treated as a 21-and-over couple on the day, even if they were 20 when they lodged the Notice of Marriage. Plan around the solemnisation date, and if a birthday falls close to it, confirm which rules apply before you choose between the consent route and marrying freely.

Minimum age for a Muslim marriage (ROMM)

Muslim marriages are registered with the Registry of Muslim Marriages (ROMM) under the Administration of Muslim Law Act, a separate legal framework from the Women’s Charter that governs civil marriage. The headline figure is the same: “the minimum age for a Muslim marriage in Singapore is 18 years old.” But two details differ from civil marriage:

• The age is counted differently. For ROMM it is “calculated based on the date of birth at the point of marriage application” — not at the solemnisation day as in a civil marriage.
• There is a narrow religious exception. The Act allows that “a Kadi may in special circumstances solemnise the marriage of a girl who is below 18 years of age” — a limited provision, exercised by a Kadi, not a general right to marry younger.

ROMM also runs its own tracks for younger couples: a defined process where “at least one party [is] below 21 years old,” and a separate one “if the bride is below 18 years old.” For the full pathway — the wali’s consent, the Kadi and the supporting documents — see our ROMM Muslim marriage guide, and for how the two systems compare, ROM vs ROMM explained.

A note on witnesses

The age rules are not only about the couple. At a civil solemnisation you need two witnesses, and each must be 21 or older — a point couples often miss when they ask a younger sibling or friend on the day. Line up witnesses who meet the age rule when you invite them; our guide to witnesses for your ROM covers what they must bring and do.

What it costs

Age affects which licence you need, and the licences are priced differently:

• The ordinary marriage licence is S$42 where at least one of you is a Singapore Citizen or PR, or S$380 if both are foreigners.
• The Special Marriage Licence (including the below-18 route) is S$280 where at least one is a citizen or PR, or S$380 if both are foreigners.

These are the current figures on the Our Marriage Journey fee schedule; reconfirm them on the portal before you pay, as official fees can change.

Frequently asked questions

What is the legal minimum age to marry in Singapore? Eighteen. A marriage where either party is below 18 is void under the Women’s Charter unless a Special Marriage Licence has been granted by the Minister.

Can I marry at 18 without my parents’ permission? No. Between 18 and 20 you need your parents’ or legal guardian’s written consent, plus a marriage preparation programme where a citizen or PR is involved — unless you are already divorced or widowed, in which case consent is not required.

At what age can I marry without anyone’s consent? At 21. From 21, each party can decide for themselves, subject to the usual marriage requirements.

Is my age taken on the wedding day or the application day? For a civil marriage, it is your age “as at day of solemnization.” For a Muslim marriage, it is calculated from your date of birth at the point of application.

Is the minimum age different for a Muslim marriage? The minimum is also 18, but ROMM counts it from the application date and allows a narrow exception where a Kadi may, in special circumstances, solemnise the marriage of a girl below 18.
