If you have already decided you want out and your spouse will not consent to a separation route, an unreasonable behaviour divorce Singapore filing under section 95(3)(b) of the Women’s Charter is almost certainly the path you will end up on. It is the most-pleaded fact in our divorce list at the Family Justice Courts, and on most weeks at my desk it accounts for the majority of the new matters that come through the door.
I am Wahab. I run A.W. Law LLC in Chinatown and I have drafted statements of particulars for unreasonable behaviour pleadings across roughly a decade of Singapore family practice. The most common opener I hear is “he’s just impossible” or “she’s just unbearable”, which by itself is not enough. This post walks through what section 95(3)(b) actually requires, the categories of conduct the Singapore courts have accepted, what makes a set of particulars hold up, and where the new Divorce by Mutual Agreement route may now be a cleaner alternative.
What section 95(3)(b) actually says
Under section 95(3)(b) of the Women’s Charter, one of the six facts that proves the marriage has broken down irretrievably is that the respondent has behaved in such a way that the petitioner cannot reasonably be expected to live with them. That is the whole statutory test. The behaviour has to be the respondent’s, and the impossibility of continuing the marriage has to be the petitioner’s.
The legal test is partly subjective and partly objective. The court asks whether a reasonable person, looking at this particular petitioner with their characteristics, history, and circumstances, would conclude that this petitioner cannot reasonably be expected to live with this respondent given the conduct alleged. Singapore lawyers sometimes call it the “this petitioner” test because it is not a one-size threshold. A pattern that one spouse might brush off, another spouse, with their particular sensitivities and history, may genuinely be unable to live with.
A few things the test is not. It is not a question of who is in the wrong. It is not a question of whether the behaviour was deliberate. It is a question of whether the marriage, viewed honestly, has crossed a line where this petitioner can no longer be expected to share a life with this respondent.
Categories the Singapore courts have accepted
There is no closed list. Section 95(3)(b) is deliberately open-textured because human marriages fail in too many ways to enumerate. That said, the patterns I see in successful unreasonable behaviour divorce Singapore filings cluster into a handful of categories.
Physical and verbal abuse
The clearest category. Hitting, shoving, slapping, throwing objects, or sustained verbal aggression amounting to intimidation. Even one serious incident with corroboration (medical report, police report, photograph, witness) usually carries the fact on its own. A pattern of lower-level incidents over months also suffices. If safety is currently the issue, a Personal Protection Order at the Family Justice Courts is a separate application that can come first and does not require a divorce filing.
Emotional abuse and neglect
Chronic belittling. Controlling who you see and when. Refusing to communicate for weeks at a time. Gaslighting, by which I mean repeatedly denying things both of you know happened until the petitioner doubts their own memory. Singapore courts have accepted these where the pattern is sustained and corroborated by messages, third-party witnesses, or counsellor records.
Financial irresponsibility
Gambling away household money. Running up debts the other spouse only finds out about when the demand letters arrive. Bankruptcy from sustained poor management. I have particularised cases where a husband’s poor financial management led to debts of around S$250,000 and a personal bankruptcy that the wife was kept in the dark about for over a year. That kind of pattern, properly evidenced, comfortably crosses the threshold and can also feed into the division of matrimonial assets argument, because dissipation of shared property is something the court will weigh under section 112.
Substance and addiction issues
Sustained alcohol abuse, drug dependency, or severe gambling addiction where the conduct affects the household. The fact is not the addiction itself. It is the conduct flowing from it: missed work, household neglect, broken commitments to the children, financial damage, episodes of aggression.
Refusal of marital relations
A sustained refusal of intimacy over a long period has been accepted in Singapore as falling within section 95(3)(b). I have seen the courts accept particulars where intimacy was refused for ten years or more without medical reason and without any willingness to discuss the issue. This is one of the more sensitive categories to plead, and the particulars need to be specific about the duration and the petitioner’s attempts to address it.
Improper association
Where the petitioner suspects adultery but cannot prove it directly, sustained suspicious association with a third party can sometimes be pleaded as unreasonable behaviour. The classic pattern is a spouse spending most evenings and weekends with one specific other person, taking trips together, and refusing to explain when challenged. This category is the standard fallback when adultery is the underlying suspicion but the evidence will not stretch that far.
Persistent neglect of family responsibilities
Sustained absence dressed up as “work”. Spending the bulk of waking hours on gaming or social media. Refusing to participate in childcare, school events, family meals, or any household functioning. The conduct has to be sustained and harmful, not just irritating. One late night a week is not unreasonable behaviour. Six months of the petitioner running the household alone while the respondent treats the marriage as a free hotel is.
Cumulative behaviour
This is the one most petitioners do not realise is available. The Singapore courts have explicitly recognised that incidents which on their own would be trivial can, taken together, cross the section 95(3)(b) threshold. I have drafted statements of particulars where roughly thirty mild incidents over two or three years (none of which would have stood alone) added up to a clean unreasonable behaviour case. The pleading has to tie them together coherently and show that the cumulative effect is what made continued life together unreasonable.
What makes the particulars hold up
The particulars are the numbered list of incidents in the statement of particulars filed with the Writ. They are the spine of the case. Three things separate particulars that hold up from particulars that get pushed back.
- Specific dated incidents. “On or around 14 March 2024, the respondent shouted at the petitioner in front of the children and refused to speak to her for the following six days.” Not “he is always rude”. Dates, places, what was said, what was done.
- Supporting evidence where it exists. Photographs of injuries or damaged property. Screenshots of messages. Bank statements showing the gambling. Police reports. Medical reports for abuse. Counsellor records. Not every particular needs documentary backup, but the most serious ones should where it is available.
- A coherent narrative. The particulars together should tell the story of why this petitioner can no longer be expected to live with this respondent. Twenty disconnected complaints read as a list of grievances. The same twenty, ordered to show a pattern of escalation or sustained harm, read as an unreasonable behaviour case.
What does not usually qualify
The honest list, because clients ask. A single argument, even a bad one. “We have grown apart.” Standard relationship friction over chores, in-laws, parenting style, or money where neither side is doing anything outrageous. Disagreements about religion or lifestyle without conduct flowing from them. Loss of physical attraction. None of these on their own gets you over the section 95(3)(b) line.
If your situation is closer to the “we have just grown apart” end of the spectrum, the introduction of Divorce by Mutual Agreement on 1 July 2024 changes the picture. Where both spouses agree the marriage has broken down, the new sixth fact under section 95(3)(f) lets you file jointly without anyone having to plead fault against the other. For couples in honest mutual breakdowns, that route is now usually cleaner than dressing the situation up as unreasonable behaviour. The DMA route still has to satisfy the court that the breakdown is genuine, and the three-year bar still applies, but it removes the need to invent a fault narrative where there is not one.
Picking unreasonable behaviour vs other facts
If you are working through which of the six facts fits your situation, my grounds for divorce in Singapore post lays out all six side by side. The short version for unreasonable behaviour: it is the right fact when the marriage is plainly over, your spouse will not consent to a separation route, you are not prepared to wait three or four years for time-based separation, and the conduct on the respondent’s side is real and provable. It is the wrong fact when both of you actually agree it is over, in which case DMA is now usually the better route, or when the situation is genuinely just incompatibility without conduct.
Where you are not sure whether the conduct rises to the threshold, that is exactly the question a Discovery Session is meant to answer.
What to do next
Most unreasonable behaviour divorces in Singapore turn on the quality of the particulars rather than on whether the conduct is dramatic enough. Wahab’s job, when you bring the situation to A.W. Law, is to listen to what has actually been happening, identify the incidents that will read as unreasonable behaviour to a Singapore family judge, and tell you honestly whether section 95(3)(b) is the right fact for your case or whether DMA, separation, or one of the other facts will serve you better.
If you are weighing this and want a straight read on what your particulars would look like and whether they would carry, the first ten minutes with me are free. Book a Divorce Discovery Session and we will work it out together. English, Malay, Mandarin, Tamil, or Vietnamese, with translation staff on hand for each.
