Many people assume Singapore has a menu of grounds for divorce: adultery, cruelty, abandonment and so on. In fact, the Women’s Charter 1961 recognises only one ground: the marriage has irretrievably broken down. Everything else you may have heard of is a “fact”, one of six legally defined ways of proving that breakdown to the court.
Since 1 July 2024 there have been six facts, with divorce by mutual agreement joining the original five. Which fact you plead shapes the tone of your case, the evidence you need and, in some situations, how soon you can file. This guide explains each fact, the proof it requires and how to choose between them.
Irretrievable breakdown: the only ground for divorce
Under section 95 of the Women’s Charter, the court can dissolve a marriage only if it is satisfied that the marriage has irretrievably broken down, and you can only prove that by establishing at least one of the six facts. Even where a fact is made out, the court retains a safeguard: if it considers, on all the evidence, that the marriage has not actually broken down irretrievably, it can refuse the divorce.
Remember also that pleading a fact does not get around the other threshold rules. You must generally have been married at least three years before filing, a separate bar with its own narrow exceptions, explained in our guide to divorcing before three years of marriage.
The six facts at a glance
| Fact | What you must show | Minimum period |
|---|---|---|
| Adultery | Spouse committed adultery and you find it intolerable to live with them | None |
| Unreasonable behaviour | Spouse behaved such that you cannot reasonably be expected to live with them | None |
| Desertion | Spouse deserted you, intending to end the marriage | 2 years continuous |
| Separation with consent | You have lived apart and your spouse consents to the divorce | 3 years continuous |
| Separation without consent | You have lived apart; no consent needed | 4 years continuous |
| Mutual agreement | Written agreement that the marriage has irretrievably broken down | None |
The six facts explained
Adultery
You must show that your spouse had voluntary sexual intercourse with someone else, and that you find it intolerable to live with them. Unless your spouse admits it, adultery is usually proved through circumstantial evidence (most commonly a private investigator’s report), which adds cost. Two limits matter: you cannot rely on your own adultery, and if you continue living with your spouse for more than six months after learning of the adultery, you can no longer rely on that instance of it.
Unreasonable behaviour
This is historically the most commonly pleaded fact, because it has no waiting period and covers a wide range of conduct: violence or threats, chronic gambling or drinking, financial irresponsibility, controlling behaviour, prolonged refusal of intimacy, or simply a sustained failure to communicate or contribute to the family. You give evidence through particulars (specific dated examples of the behaviour) in your court papers. The test is whether you cannot reasonably be expected to live with your spouse, judged in the context of your particular marriage. The particulars can be kept factual and measured; in uncontested cases spouses often agree on a moderate set of particulars to avoid inflaming matters.
Desertion for two years
Desertion means your spouse left you, without your agreement and without good reason, intending to bring the marriage to an end, and stayed away for a continuous period of at least two years. It is rarely used in practice: if a couple has been apart that long, it is usually simpler to wait for a separation fact or to use mutual agreement, since desertion requires proving your spouse’s intention to abandon the marriage.
Three years’ separation with consent
You must have lived apart for a continuous period of at least three years, and your spouse must consent to the divorce being granted. Living apart is not just physical distance: it means living in separate households, with the marriage effectively at an end. It is possible to be separated under the same roof, for example in the same HDB flat, if you genuinely lead separate lives: separate rooms, meals, finances and no shared domestic life. Expect the court to look at such arrangements carefully. Evidence typically includes the date separation began, living arrangements, and your spouse’s written consent given in the court process.
Four years’ separation
After four years of continuous separation, you can obtain a divorce without your spouse’s consent. This is the fact of last resort for people whose spouse refuses to cooperate: no fault needs to be shown and no agreement is required, only proof of the separation itself and when it began.
Divorce by mutual agreement (since 1 July 2024)
The newest fact lets both spouses jointly declare, in a written agreement, that the marriage has irretrievably broken down, without blaming either side and without waiting out years of separation. The agreement must set out the reasons for concluding the marriage has broken down, the efforts made at reconciliation, and the consideration given to the arrangements for your children and finances. The court keeps a safeguard: it can reject the agreement and refuse the divorce if it considers there is still a reasonable possibility of reconciliation, and it can direct the couple to mediation or counselling. In practice, mutual agreement pairs naturally with the simplified track: see our guide to uncontested divorce in Singapore.
Which fact should you choose?
Where more than one fact is available, choose the one you can prove most easily and that causes the least collateral damage. A few practical rules of thumb:
- If you both agree the marriage is over, mutual agreement is usually the least acrimonious route and needs no separation period.
- If your spouse will not engage at all, unreasonable behaviour (no waiting period) or four years’ separation (no consent needed) are the workhorses.
- Adultery is often the hardest and most expensive fact to prove; many people who could plead it choose behaviour or mutual agreement instead.
- A fault-based fact does not generally win you more: asset division and custody are decided on contributions and the children’s welfare, not on whose fault the divorce was. See how the court approaches the division of matrimonial assets.
Whichever fact you plead, it is only the doorway into the case. The fact gets you the interim judgment; the arrangements for children, maintenance and property are decided in the second stage.
