A void marriage is one that the law treats as never having been a valid marriage at all. A voidable marriage is a valid marriage that stays valid until a court annuls it. Both are dealt with under Part 6 of the Women’s Charter 1961, and both end in a judgment of nullity, but the practical consequences of being in one category rather than the other are very different.
The short version: if your marriage is void, you were never legally married, though you will usually still want the court to say so on paper. If your marriage is voidable, you are married right now, and you stay married until you do something about it. That difference drives everything else: the urgency, the time limits, and what you can safely do next.
What makes a marriage void
Section 105 of the Women’s Charter sets out when a marriage solemnised in Singapore is void. In broad terms, a marriage is void where:
- The parties are within the prohibited degrees of kinship: they are too closely related for the law to recognise a marriage between them.
- Either party was already lawfully married at the time of the ceremony. A second marriage entered into while the first subsists is void, and bigamy is also a criminal matter.
- The parties are not respectively male and female for the purposes of a civil marriage under the Charter.
- The marriage involves Muslim law: a Muslim marriage solemnised under the Women’s Charter, or a civil marriage where either party is Muslim, is void under the Charter. Muslim marriages belong to the Syariah Court and the Administration of Muslim Law Act.
- The solemnisation requirements were not complied with in the circumstances the Charter defines, for example where the formal requirements as to a valid marriage licence or the person solemnising were not met and the statute treats that failure as fatal.
- A party was under the minimum age for marriage without the special licence the law requires.
These are status defects. They go to whether a marriage could ever have existed between these two people in these circumstances, not to how the relationship turned out.
Why you still go to court for a void marriage
If the marriage was never valid, why bother with proceedings? Because the rest of the world runs on documents. The Registry of Marriages holds a record of a solemnisation. HDB, CPF Board, banks, employers and the Immigration and Checkpoints Authority will act on what is recorded, not on your explanation of section 105. A judgment of nullity is the document that resolves that.
There is a second reason. Whether a marriage is void is a legal conclusion, and reasonable people get it wrong. Assuming you were never married and then remarrying on that assumption is a serious risk if the assumption is mistaken. The court’s declaration removes the doubt.
What makes a marriage voidable
Section 106 deals with voidable marriages. These are defects in consent, capacity or the state of affairs at the time of the marriage, rather than defects in the marriage’s basic legal possibility. A marriage is voidable where:
- The marriage has not been consummated owing to the incapacity of either party to consummate it.
- The marriage has not been consummated owing to the wilful refusal of the respondent to consummate it.
- Either party did not validly consent to the marriage, because of duress, mistake, unsoundness of mind or otherwise.
- Either party, though capable of giving valid consent, was suffering from a mental disorder of such a kind or extent as to be unfit for marriage.
- The respondent was suffering from a communicable venereal disease at the time of the marriage.
- The respondent was pregnant by another man at the time of the marriage.
Notice how many of these are framed around the respondent. You cannot rely on your own wilful refusal to consummate, and several of the other grounds are about a condition affecting the other party. That framing matters when you are working out whether you have a case at all, and how non-consummation is actually proved goes into the most common ground in detail.
The two categories side by side
| Void marriage | Voidable marriage | |
|---|---|---|
| Legal status before any court order | Never was a valid marriage | A valid marriage in every respect |
| Typical grounds | Prohibited degrees, existing marriage, Muslim law, defective solemnisation, under age without licence | Non-consummation, lack of valid consent, mental disorder, venereal disease, pregnancy by another man |
| Can you remarry without a court order? | Legally the earlier marriage does not exist, but do not rely on this without a declaration | No: you are married until annulled |
| Time limits | No equivalent three-year window | Statutory bars apply, including a three-year window for several grounds |
| Can a third party’s position be affected? | Yes, particularly where bigamy is involved | Generally only the parties can apply |
| Effect of the court’s judgment | Declares the position that already existed | Ends a marriage that was valid until then |
Time limits and other bars
Voidable marriages come with statutory restrictions in section 107 that void marriages do not. In general terms, for the voidable grounds other than non-consummation, proceedings must be brought within three years of the marriage. There are also broader bars: the court may refuse a decree where the applicant, knowing they could have avoided the marriage, behaved in a way that led the respondent reasonably to believe no annulment would be sought, and where granting the decree would be unjust to the respondent. Further specific bars attach to particular grounds.
These provisions are technical and the way they apply depends on which ground you are relying on. Do not assume a particular bar does or does not apply to your ground; check it with a lawyer before you plan around it. The time limits on annulment applications covers the framework in more detail, including what to do if the window has closed.
No three-year marriage bar
One point catches almost everyone by surprise. A divorce generally cannot be filed within three years of the marriage, subject to narrow exceptions for exceptional hardship or depravity. That restriction is a divorce rule. It does not apply to nullity. If you have a genuine ground for annulment, the fact that you married eight months ago is no obstacle, which is precisely why annulment is worth investigating in a very short marriage rather than waiting out the three years for a divorce.
Children, assets and maintenance
The most persistent myth about annulment is that it wipes out everything, including the children’s status. It does not.
Where a voidable marriage is annulled by a decree of the court, the children of that marriage remain legitimate. Their position as your children, for maintenance, for inheritance and for everything else, is unaffected by the annulment.
The court also has the same powers over ancillary matters in nullity proceedings as it has in divorce. That means it can make orders on custody, care and control and access, on maintenance for a spouse and for children, and on the division of matrimonial assets. Annulment is not a shortcut around financial responsibilities. In practice many annulments are short, childless marriages where there is little to divide and no ancillary dispute, but that is a feature of the facts, not a rule of law.
Where a flat or CPF monies are involved, the consequences are real and worth working through before you file. What happens to an HDB flat and CPF after an annulment sets out the practical issues.
Which one applies to you, and what to do next
Start with the facts at the date of the marriage, not the date the relationship broke down. Annulment looks backwards to a defect that existed at or before the ceremony. Things that went wrong afterwards (infidelity, financial pressure, drifting apart) are the territory of the facts that prove irretrievable breakdown in a divorce, not of nullity. The overview at annulment compared with divorce is a useful sanity check if you are not sure which route fits.
If a defect did exist at the outset, the next question is which category it falls into, because that sets your timetable. A voidable marriage subject to a three-year window rewards moving early; a void marriage is less time-pressured but still needs a declaration before you can safely treat yourself as unmarried.
Either way the mechanics are the same court process, described in the step-by-step annulment process, and the complete guide to annulment in Singapore ties the pieces together. Because the grounds are narrow and the bars are technical, this is an area where a short conversation with a lawyer early saves months.
