Understanding Bigamy In Singapore: What You Need To Know

by 22 March 2025Knowledge & Insights

Bigamy in Singapore is a serious offence that can lead to severe legal consequences. But what is bigamy in Singapore? It occurs when a person who is already legally married enters into another marriage without legally ending the first.

For non-Muslims, this is strictly prohibited under the Women’s Charter, while for Muslims, marriages are governed by Syariah Law with specific conditions for polygamy. If caught, offenders can face imprisonment, fines, or both.

 

Is Bigamy Legal In Singapore?

No, bigamy is illegal in Singapore for non-Muslims. Under the Women’s Charter, any person who marries another while still legally married to their current spouse commits a criminal offence. This applies regardless of whether the second marriage takes place in Singapore or overseas.

However, there is an exception for Muslim marriages, which Syariah Law governs under the Administration of Muslim Law Act (AMLA). A Muslim man may be allowed to take more than one wife, but this is subject to strict approval by the Syariah Court. He must demonstrate that he can financially support multiple wives and that the additional marriage is justifiable. Without official approval, any subsequent marriage could still be considered illegal.

However, there is an exception for Muslim marriages, which are governed by Syariah Law under the Administration of Muslim Law Act (AMLA). A Muslim man may be allowed to take more than one wife, but this is subject to strict approval by the Syariah Court. He must demonstrate that he is financially capable of supporting multiple wives and that the additional marriage is justifiable. Without official approval, any subsequent marriage could still be considered illegal.

For non-Muslims, there are no exceptions—any attempt to contract a second marriage without legally dissolving the first is punishable under Singapore law.

 

Legal Consequences Of Bigamy In Singapore

Committing bigamy in Singapore carries severe legal penalties and can have lasting consequences on a person’s life. The key legal repercussions include:

1. Criminal Charges & Penalties

Since bigamy is a criminal offence under the Women’s Charter, offenders can face:

  • Imprisonment for up to seven years
  • A fine
  • Or both

This means that anyone who knowingly enters into a second marriage while their first marriage is still legally binding risks having a criminal record.

2. The Second Marriage Is A Void

Under Singapore law, a bigamous marriage is considered legally invalid. This means that the second spouse has no legal rights in the marriage, including claims over marital assets or inheritance.

3. Divorce Proceedings & Family Impact

If bigamy is discovered, the first spouse has grounds to file for Divorce. The consequences of this can include:

  • Division of Assets: The legally recognised spouse may have a stronger claim over shared property and finances.
  • Spousal and Child Maintenance: The first spouse may seek financial support, especially if children are involved.
  • Child Custody Disputes: The Court may factor in bigamy when deciding parental responsibility and custody arrangements.

4. Immigration & Legal Status Issues

Engaging in bigamy can affect foreigners’ ability to stay in Singapore. If the second spouse is a foreigner, their Long-Term Visit Pass (LTVP) or Permanent Residency (PR) application could be denied or revoked.

5. Reputation & Employment Risks

Having a criminal conviction for bigamy can damage a person’s reputation and affect their employment opportunities. Many employers conduct background checks, and a criminal record could limit career advancement or job eligibility, particularly in professions requiring high ethical standards.

 

How Bigamy Cases Are Investigated In Singapore

The authorities take bigamy seriously, and investigations typically include:

  • Reviewing marriage records to confirm multiple registrations.
  • Gathering testimonies and documents from the affected spouses.
  • Checking for false declarations in marriage registrations.

If found guilty, the offender will have a criminal record, which can affect employment and travel opportunities.

Exceptions & Special Cases

There are very few exceptions where a second marriage may not be considered bigamy:

  • If the first marriage is declared null and void by a Court.
  • If the first spouse is presumed dead after being missing for several years.
  • If the individual was unaware of the existence of the first marriage due to fraud.

 

What To Do If You Suspect Bigamy

If you suspect that your spouse or someone you know is involved in bigamy in Singapore, taking the right steps can help protect your legal rights and ensure that the matter is handled appropriately. Here’s what you should do:

1. Gather Evidence

Before taking legal action, it is important to collect evidence to support your claim. This can include:

  • Marriage certificates – Check for records of multiple registered marriages.
  • Witness testimonies – Statements from people who may have knowledge of the second marriage.
  • Financial transactions – Evidence showing financial support or shared assets with a second spouse.
  • Social media activity – Photos, posts, or announcements that suggest a second marriage.

Having solid proof will strengthen your case if you decide to report the issue or take legal steps.

2. Seek Legal Advice

Consulting a lawyer is one of the most important steps to take if you suspect bigamy. A legal expert can:

  • Advise you on your rights and options.
  • Help you understand whether the marriage is legally valid.
  • Guide you through the legal process if you decide to report the offence or file for Divorce.

If bigamy is proven, you may be able to take legal action to invalidate the second marriage and seek remedies such as Divorce, spousal maintenance, or child custody arrangements.

3. Report To Authorities

Bigamy is a criminal offence in Singapore. If you have strong evidence, you can report the matter to the police or relevant authorities. The authorities will investigate and take appropriate legal action if necessary. The investigation process may involve:

  • Reviewing official marriage records to check for multiple registrations.
  • Questioning the accused and witnesses for further details.
  • Gathering supporting documents such as financial records and travel history..

4. Consider Divorce Proceedings

If you are legally married to someone who has committed bigamy, you may wish to file for Divorce. This allows you to:

  • Legally separate from your spouse.
  • Seek division of marital assets to protect your financial interests.
  • Claim maintenance for yourself and any children affected by the situation.
  • Settle child custody matters to ensure proper care for your children.
