A psychiatric diagnosis lands in a parenting dispute like a bomb. One parent fears the label will cost them their children. The other parent fears the illness will hurt the children. Australian courts have seen both fears play out for decades, and the case law gives a clearer answer than most parents expect: the diagnosis itself decides very little. What decides the case is evidence about risk, insight, treatment, and what each parent actually does. This article explains how judges analyse a parent's mental health under section 60CC of the Family Law Act 1975, and what real cases say about each situation you might be in. One note on language before we start: Australian legislation no longer uses the word custody. Courts make parenting orders about where a child lives and how much time the child spends with each parent. This article uses custody in its everyday sense because that is how most people search for and talk about the problem.
Introduction
Q1: I have been diagnosed with a mental illness. Will I automatically lose custody of my child?
A: No. Australian courts do not remove children because of a diagnosis. They look at how your condition affects your actual ability to care for your child, and whether treatment and insight keep any risk under control. Even a father diagnosed with delusional disorder was given the chance to contest the evidence rather than being cut off. Reference: Sandwell [2019] FamCA 320
Q2: My ex has mental health problems and I am scared for our child. Can I stop them seeing the child?
A: Not on fear alone. Your concern, even if genuine, does not give you a veto over the other parent's time. You need evidence of a real risk to the child, or proof that forcing contact would measurably damage your own capacity to care. Reference: Keane [2021] FamCAFC 1
Q3: If the risk from a parent's condition is real, will the court cut that parent out of the child's life completely?
A: Only as a last resort. Before making a no-contact order, the court must weigh safer alternatives such as supervised time or letters, and explain why none of them would reduce the risk enough. Skipping that step is appealable error. Reference: Blinko [2015] FamCAFC 146
What Does the Law Say About Mental Illness and Child Custody?
Start with what the legislation actually says. Nothing in the Family Law Act 1975 makes a mental illness a reason to refuse a parenting order, and depression, anxiety, bipolar disorder and schizophrenia appear nowhere in the Act as disqualifications. What the Act does say is that the child's best interests are the paramount consideration, and section 60CC of the Family Law Act 1975 lists what the court must weigh to work out those interests: the safety of the child and of each person who cares for the child, the child's developmental and emotional needs, and the capacity of each parent to meet those needs, among other factors.
Mental health enters that framework through three practical questions:
- Does the condition create an unacceptable risk of harm to the child? Risk is assessed on evidence of what the parent has actually done and what the condition actually causes, not on the name of the illness. The court must identify the risk, measure how serious it is, and ask whether safeguards can bring it down to an acceptable level: Blinko [2015] FamCAFC 146.
- Does the condition impair the parent's capacity to care? Where mental health is in issue, the court usually orders a parenting capacity assessment by a court-appointed single expert, typically a psychiatrist or psychologist who interviews both parents, reviews medical and police records, and reports to the court rather than to either side: Sandwell [2019] FamCA 320.
- How does one parent's mental state affect the other parent's caregiving? Family lawyers call this the Re Andrews principle. If forcing contact would so damage the primary carer's psychological health that their care of the child deteriorates, that damage counts as a risk to the child. But it must be proved with evidence, not assumed: Keane [2021] FamCAFC 1.
Notice what this means for the most common worry. If you are asking whether you can lose custody for depression and anxiety, the realistic answer is that these conditions almost never decide a case by themselves. Judges see them constantly. The question is always whether the condition is managed, and whether it shows up in the evidence as harm or risk to the child.
The same framework explains why courts treat cutting a parent off as an extreme step:
"such orders will necessarily wholly prohibit the child, during their childhood and adolescence, from ever having any form of relationship with the non-resident parent, again, a potentially grave consequence. Such an outcome needs to be arrived at only after a careful evaluation of all of the other options which might work to enable the child to have the benefit of some kind of relationship with the non-resident parent"
Before a judge removes a parent from a child's life, then, the judge must test every softer option, work out how risky each one really is, and explain why none of them works. A diagnosis can start that inquiry, but it can never end it.
Core Point: The diagnosis is a starting point, not a verdict. Courts decide custody on evidence of risk, insight, treatment and day-to-day parenting, filtered through the best interests factors in section 60CC of the Family Law Act.
Why Does Misunderstanding This Cost Parents So Much?
Reading across the cases, most of the damage comes not from the diagnosis itself but from how parents react to it. Parents who misread the law tend to make one of three mistakes, and the case law shows each one backfiring:
- Hiding the condition or refusing treatment. Courts read concealment and lack of insight as the real danger. A parent who says the doctors are all wrong looks riskier than a parent who accepts help, because an unacknowledged illness is an unmanaged one: Sandwell [2019] FamCA 320.
- Relying on fear instead of evidence. A worried parent who arrives at court with genuine distress but no medical evidence can watch the court order exactly the unsupervised time they dreaded: Keane [2021] FamCAFC 1.
- Refusing every compromise. A parent whose position leaves no room for the children to have any relationship with the other parent can be found to be the psychological risk themselves, and lose primary care entirely: Gabbey & Cadriel [2024] FedCFamC1A 60.
The stakes are easiest to see in the case where everyone acted in good faith and the orders still went too far.
The father had not seen his daughter since 2009, when she was 11 months old. The mother said her fear of him, built on a history of violence, ran so deep that she could not cope with the child spending even supervised time with him. A psychiatrist gave evidence that if the child had anything to do with the father, the mother might decompensate, meaning her mental state could deteriorate to the point where her care of the child would be seriously affected. The trial judge accepted the fear was genuine and rational, found no evidence that the father himself would harm the child, and still ordered that he have no time and no communication with her at all.
The father appealed. He had offered a menu of gentler options: cards and gifts on special occasions, a few supervised visits a year, closely supervised time supported by counselling, or therapy to prepare the child and mother for reunification.
Outcome: Appeal allowed and the case sent back for rehearing. The trial judge made no error about the facts or the law, but he never properly evaluated the father's proposals or measured how much each option would actually harm the mother's psychological health and parenting. A court cannot erase a parent from a child's life without first explaining why every safer option fails.
Key Point: Even a genuine, medically supported risk does not end the inquiry. The court must measure the risk against every workable safeguard. A parent who keeps offering realistic safeguards is never wasting their time, and a parent who refuses to discuss any of them is taking a serious gamble.
How Do Courts Handle Different Mental Health Scenarios?
Three situations cover most disputes where a parent's mental health is raised. The law treats them differently, and so should you.
Scenario 1: You are the parent who has been diagnosed
Common misconception: A serious diagnosis such as delusional disorder, schizophrenia or bipolar disorder means you will never get more than supervised time, so there is no point cooperating with the court process.
Legal truth: The court's focus is on insight and treatment, not the label. A parent who accepts the condition, follows treatment and shows the court a managed illness is in a completely different position from a parent who denies everything, because denial tells the judge the risk is unmanaged.
"Either the father is mentally well, or he is mentally ill and does not believe or accept that it is so. And it is not, in my view, a case where there are just differences of opinion, although there clearly are differences of opinion."
The couple's two children were just three years old and 18 months old when the dispute reached court. A court-appointed single expert, a psychiatrist, diagnosed the father with delusional disorder, found he lacked insight into his illness, and recommended consistent psychiatric treatment at least fortnightly for five years. The subpoenaed records behind that opinion included an acute psychotic episode linked to substance abuse.
The father rejected the diagnosis. He was referred to a psychiatrist who could have become his treating doctor, but he did not show that doctor the single expert report and stopped after two visits when the doctor said he was well. His lawyers then arranged an assessment with another psychiatrist, Dr H, who never saw the subpoenaed records or the single expert report and concluded the father had no delusional disorder at all.
Outcome: The court let Dr H's report into evidence, but only on the narrow question of the father's mental health, because the stakes justified it. The single expert's diagnosis would otherwise consign the father to limited supervised time with his children or no time at all. The judge framed the real issue directly: could a father motivated to present as well manage to do so while actually being ill and lacking insight into it?
If you are the diagnosed parent, the practical steps follow from how this evidence works:
- Engage honestly with the court-appointed single expert. The parenting capacity assessment carries far more weight than any report you commission yourself.
- Keep treating. Regular appointments, medication compliance and a treating practitioner who can describe your progress are the strongest evidence you can build.
- Show insight. Telling the court you understand the condition and what it requires persuades judges far more than attacking the diagnosis.
- Do not shop for a friendly opinion. Courts discount reports that rest only on what you told the doctor, and the shopping itself can read as lack of insight.
Scenario 2: The other parent has the mental health problem and you are worried
Common misconception: If your fear for the child is genuine, the court will protect you and stop or restrict the other parent's time.
Legal truth: Genuine fear is only the start. You must prove either a real risk of harm to the child from the other parent's condition, or that forcing contact would measurably damage your own capacity to care for the child. The court will not simply infer that damage from the strength of your feelings.
"it is an error to assume that, in each and every case where a parent is concerned about the safety of a child in the other parent's care, the court will infer that there is an unacceptable risk that the concerned parent's parenting capacity will be adversely impacted. To do so risks elevating those fears to an extent that it overshadows the totality of considerations set out in s 60CC of the Act."
The mother of a four year old alleged the father had sexually abused the child. The trial judge found the father had committed family violence towards the mother, but rated the abuse allegation so unlikely that no real chance of it could be established, and ordered supervised time that would move to unsupervised time.
On appeal the mother argued the orders would break her, so her caregiving capacity would collapse. The problem was her own evidence. She specifically denied having poor mental health, and the single expert agreed she did not. She called no treating psychologist, psychiatrist or therapist to say the orders would harm her ability to parent. Her case rose no higher than saying she would be very distressed, and she told the court she would seek therapy if that became necessary.
Outcome: Appeal dismissed. The court held that her evidence established no more than a speculative possibility of impaired parenting. Fear, without evidence that it measurably impairs your care of the child, cannot veto the other parent's time.
Two Full Court decisions, five years apart, show exactly where the line sits:
| Comparison | Blinko [2015] | Keane [2021] |
|---|---|---|
| Nature of the fear | Genuine and rational, built on a history of violence | Genuine, but the abuse allegation was found very unlikely |
| Medical evidence | Psychiatric evidence the mother would decompensate | No treating practitioner evidence; expert found no poor mental health |
| Proven effect on caregiving | Care of the child would be seriously affected | No more than a speculative possibility |
| Outcome | No-time order stood on the facts; remitted only so safer options could be weighed | Unsupervised time ordered; appeal dismissed |
Key: The decisive factor is not how afraid you are. It is whether independent evidence shows a detectable impairment of your caregiving, or a real risk to the child. The mother in Blinko had psychiatric evidence. The mother in Keane had only her own distress.
If you are the worried parent, build the case the court can actually act on:
- See a treating psychologist or psychiatrist and let them document how contact arrangements affect your functioning.
- Collect evidence of concrete incidents that affect the child: hospitalisations, police callouts, threats, missed handovers, erratic behaviour the children witnessed.
- Ask for safeguards in proportion to the evidence, such as supervised time or a staged increase, rather than demanding no contact from the start.
- Stay open to therapy and support. The Keane mother's willingness to get help if needed was part of why the court trusted her care would hold up.
Scenario 3: Your reaction to the other parent becomes the risk
Common misconception: Showing the court the full depth of your fear and refusing all cooperation proves how dangerous the other parent is.
Legal truth: Parenting orders are not a reward for the more sympathetic parent or a punishment for the more difficult one. If your position leaves no room for the children to have any relationship with the other parent, the court can find that the psychological risk to the children now comes from you, and it can reverse their care. The Full Court in Summerby & Cadogen [2011] FamCAFC 205 adopted the trial judge's warning:
"parenting orders ought not be made to assuage concern about injustice to one parent or the other, nor to redress what may be perceived to be some unfairness in the outcome. Nor should parenting orders be made as a form of retribution or penalty against one parent for what might be regarded as unacceptable behaviour on that parent's part, if otherwise the best interests of the child warrant that parent having the primary or sole care for the child."
The mother of two young children alleged the father had sexually assaulted her and had groomed and sexually abused the eldest child. The trial judge rejected those allegations after a full trial. What remained was the mother's stance. Asked in the witness box whether she would accept therapeutic help if the children resumed time with their father, she called the very idea ridiculous and said no therapy would likely make her feel safe.
The judge found the children would be at serious psychological risk in her sole care, and that her extreme position left no room for any middle-ground arrangement. Even the independent children's lawyer, appointed to represent the children's interests, sided with the father's proposal. On appeal, the mother argued the judge should have considered supervised time for her instead of near-total separation.
Outcome: The children went to live with the father with sole parental responsibility, and the mother was limited to cards, letters and gifts on special occasions. The Full Court upheld the substance of those orders because her own evidence made alternatives impossible, though it set aside side orders, such as a ban on going within 100 metres of the children's school, that the trial judge had never explained.
Courts reach similar endpoints when hostility turns into coaching. In Wang & Dennison (No. 2) [2009] FamCA 1251 the mother had deliberately conditioned the children to believe their father abused them, and after three years of failed therapeutic orders the court gave up on forced reunification and left any future contact for the children to choose, perhaps in adolescence. In Summerby & Cadogen [2011] FamCAFC 205 it was the father who coached the child into false abuse allegations, and it was the father who ended up with no time, even though the mother had breached orders ten times. The court was not rewarding the mother. It was refusing to expose the child to more emotional abuse.
If you recognise yourself sliding toward this scenario:
- Keep the door open to supervised time and therapeutic support. Willingness to engage is often what separates keeping primary care from losing it.
- Never coach the children, quiz them after visits, or share adult allegations with them. Judges treat that as emotional abuse of the child, whatever the other parent has done.
- Comply with orders while they stand and pursue changes through the court, not through withholding.
The disputes in this scenario often overlap with other problems we have covered. For when a court will cut off contact entirely, see When Will Courts Order No Contact With a Child? (Australia).

What Should You Do When Mental Health Enters Your Custody Case?
Four lessons run through every case in this article.
-
The diagnosis is not the decision. In Sandwell even a delusional disorder diagnosis from the court's own expert did not end the father's case. What the court cared about was insight, treatment and whether the illness was managed.
-
Real risk still forces the court to test safer options. In Blinko the mother's fragility was genuine and medically supported, yet the no-contact orders fell on appeal because the judge never explained why supervised visits or letters could not work.
-
Fear needs evidence before it moves a court. In Keane the mother's distress was real, but with no treating practitioner behind her and an expert who found her mentally well, the court refused to let her fear veto the father's time.
-
Refusing every compromise can cost you the children. In Gabbey & Cadriel the mother's rejected allegations plus her refusal of all therapy convinced the court that the risk to the children lay in her care, and the children went to the father.
| ✅ Helps your case | ❌ Hurts your case |
|---|---|
| Following treatment and showing insight into your condition | Denying a documented condition or attacking every expert |
| Evidence from treating practitioners about your functioning | Telling the court you are distressed, with nothing more |
| Proposing supervised time or staged safeguards | Demanding no contact and offering no alternatives |
| Keeping the children out of the adult conflict | Coaching children or sharing allegations with them |
A mental health problem, yours or the other parent's, does not have to end anyone's relationship with the children. The parents who come out of these cases intact are the ones who treat the illness as something to manage with evidence, not something to hide or weaponise.
