Marriage Offences in Singapore - Minors, Same-Sex, Bigamy & More

In Singapore, marriage laws are designed to safeguard the institution of marriage and protect individuals from harm. While the laws are structured to encourage healthy, consensual unions, there are various offences that can occur within the context of marriage.

Some of these offences are based on the nature of the marriage itself, such as forced child marriages or same-sex marriages, while others, like bigamy or consanguine marriages, involve breaches of legal and societal norms. Understanding these marriage-related offences is essential for both individuals and legal professionals alike.

In this blog, we’ll discuss the different types of marriage offences in Singapore, covering forced child marriage, same-sex marriage, consanguine marriage, sham marriage, and bigamy.

 

What is Forced Child Marriage and Why is It Illegal?

Forced child marriage is one of the most disturbing marriage offences. This type of marriage involves a minor being coerced or pressured into marrying someone against their will.

In Singapore, marriage before the age of 21 requires parental consent and Court approval—anything less is considered a violation of the child’s rights.

Why It’s a Serious Crime:
A forced marriage undermines the child’s ability to make free and informed decisions, which is why Singapore has strict penalties for those involved. If found guilty of arranging or facilitating a forced marriage, offenders can face up to 10 years in prison and/or a fine.

 

Consanguine Marriage: Understanding the Legal Barriers

Consanguine Marriage - Understanding the Legal Barriers

Consanguine marriages refer to unions between close blood relatives, such as siblings or a parent and child. These types of marriages are not just considered socially taboo; they are also prohibited by law in Singapore.

Why Singapore Bans Consanguine Marriages:
These marriages can have detrimental effects on offspring, both genetically and psychologically. To protect family structures and maintain public health, the law is clear that consanguineous unions are not permitted. Offenders can face imprisonment if caught in such relationships.

 

Sham Marriages: A Dangerous Game of Deception

Sham marriages are those that are entered into for fraudulent purposes, typically to gain immigration benefits or evade legal restrictions. These marriages are considered a serious crime in Singapore, as they undermine the integrity of the legal system.

What’s at Risk in a Sham Marriage?
People entering sham marriages to gain residency, citizenship, or other benefits are committing an offence that carries severe penalties. Those found guilty could face up to 10 years in prison, a fine, or both. It’s essential to understand that attempting to exploit marriage for personal gain is illegal.

 

Bigamy: The Crime of Marrying More Than Once While Still Legally Bound

Bigamy is the act of marrying someone while already married to another person. While the first marriage remains valid, the second marriage is considered void and criminal under Singapore marriage law.

Understanding the Penalties for Bigamy:
Bigamy is punishable by up to 7 years in prison, a fine, or both. The law seeks to preserve the sanctity of marriage and prevent individuals from entering into multiple marriages without proper dissolution of the first. This crime highlights the importance of fidelity and commitment in marriage.

 

The Legal Implications of Same-Sex Marriages in Singapore

The Legal Implications of Same-Sex Marriages in Singapore

While many countries are pushing for the legalisation of same-sex marriages, Singapore remains steadfast in its position. The Women’s Charter defines marriage as a union between a man and a woman, which means same-sex couples are not legally allowed to marry in Singapore.

What You Need to Know:
There are no penalties for simply being in a same-sex relationship, but the legal recognition of same-sex marriages does not exist.

Those who attempt to formalise such relationships through legal channels may find their attempts blocked, and public advocacy for the recognition of same-sex marriage remains an ongoing debate.
