In Singapore, the starting point for every custody discussion is simple. Children do best when both parents remain involved.
Our courts have repeated this for decades. Joint parenting is the default. It is the gold standard. It is the assumption that sits quietly beneath almost every custody order. And in my own practice, I rarely advise anyone to seek sole custody. It is not the norm, and it is almost never necessary.
But once in a long while, a case appears where joint custody is not merely unsuitable. It becomes impossible.
That is what made XUH v XUI [2025] SGFC 127 stand out. It is one of those very rare decisions where the Court concluded that the only way to protect the children was to depart entirely from the usual joint parenting model.
The Usual Rule: Joint Custody for Almost Everyone
The judgment itself begins by acknowledging the usual legal position.
The Judge cites the Court of Appeal’s guidance that joint parenting should be promoted because children need the love and involvement of both parents, even after a divorce. This principle is so deeply rooted that it guides almost every custody decision in Singapore.
This is why sole custody is so rare. For the Court to strip one parent of decision making power, something extreme must have happened. It is always seen as a last resort.
Why This Case Was Different
As the Judge explained, this was an exceptional situation.
After observing the Mother over half a year and reviewing the full evidence, he concluded that she was not able to make stable, child focused decisions. Her behaviour was described as unusual, disturbing and erratic.
Her conduct in court, her repeated breaches of directions, her refusal to comply with discovery, her aggressive behaviour at home, and her escalating volatility created a picture that the Judge could not ignore.
This was not a case of parents who simply could not get along. It was a case where one parent was unable to regulate her behaviour in a way that protected the children.
The Turning Point: Welfare Above Everything Else
Singapore law is very clear that the welfare of the child is the paramount consideration.
Once the Judge was satisfied that the Mother’s state of mind and behaviour made her unfit to exercise joint custody, he had to decide what would best protect the children.
At paragraph twenty nine, he stated plainly that this was an exceptional case where joint custody would not be appropriate. He found that the children’s welfare would be best served by giving the Father sole custody.
This is the core of the judgment.
- Not punishment.
- Not blame.
- A clear welfare based conclusion that the children needed stability.
The Court also granted the Father sole care and control after reviewing the children’s wishes, their discomfort around their Mother, and the pattern of behaviour that had estranged them from her.
Why Sole Custody Is So Rare in Singapore
This case illustrates beautifully why sole custody orders are unusual.
First, the threshold is extremely high. A parent must be shown to be unable to make sound, child centered decisions.
In this case, the Court found that the Mother displayed contemptuous and erratic behaviour that extended across home, correspondence and the courtroom.
Second, joint custody is not removed because a parent is difficult. The Judge went further to analyse the Mother’s mental capacity in detail.
He made clear that a person may have mental health challenges and still have the mental capacity to litigate, yet at the same time be unfit to make caregiving decisions.
This distinction is rarely explained as clearly as it was here.
Third, the Court must be convinced that joint decision making would place the children at risk.
The Judge repeatedly highlighted incidents that caused concern for the children’s safety, emotional wellbeing, and stability.
Only when all these elements lined up did the Court cross the line into the rare territory of sole custody.
A Cautionary But Hopeful Ending
What makes this judgment human is the final paragraphs.
At paragraph eighty eight, the Judge urged the Mother to take stock of her situation. He encouraged her to seek professional help and stabilise her mental state so that she could rebuild her relationship with her children.
Even after granting sole custody, the Court left a door open.
Access could be expanded if she sought psychiatric assessment, followed treatment, and showed improvement.
This is the quiet heart of family justice in Singapore.
Even in exceptional cases, the system tries to preserve the possibility of healing.
Why This Case Matters
Cases like this are rare. Sole custody is not the norm.
- It is not the starting point.
- It is not even the midpoint.
- It is the exception that only appears when a parent’s instability makes joint parenting unsafe.
This decision is a reminder that the law protects children above all.
And sometimes, when everything else fails, the Court must do the one thing it almost never does.
It must say that only one parent can safely carry the responsibility.
