Your Co-Parent Is Having a Mental Health Crisis. What Happens to Custody?

The murder trial of Massachusetts mother Lindsay Clancy has put postpartum psychosis and the treatment of serious postpartum mental health conditions back into the national conversation.

Clancy is accused of killing her three young children in January 2023. Her defense argues that she was experiencing postpartum psychosis and was not criminally responsible for her actions, while prosecutors contend the killings were deliberate. As of September 4th, 2026 a mistrial was declared due to a deadlocked jury.

The criminal case involves horrific and highly unusual circumstances. Yet the testimony has exposed questions that can arise in other families when a parent experiences a serious mental health crisis:

What happens to child custody when a parent suddenly cannot safely care for their children?

A co-parent may be hospitalized and unable to exercise parenting time. A parent may see behavior that makes them afraid to send their child to the other home. Someone who received treatment may worry that a former spouse will use the diagnosis against them in a custody dispute.

Families facing these situations may need to address both the immediate safety of the child and what custody should look like as the parent’s condition changes.

Postpartum Psychosis Is a Psychiatric Emergency

Much of the Clancy trial has centered on what was happening with her mental health before the children’s deaths and whether she was experiencing postpartum psychosis.

Postpartum psychosis is rare and serious. Symptoms can include hallucinations, delusions, paranoia, disorganization, confusion, insomnia, and unusual behavior, and the condition generally requires immediate medical attention.

The testimony in Clancy’s case has also highlighted how complicated identifying and treating a psychiatric crisis can become. Jurors have heard about multiple providers, medications, sleep problems, hospitalization, and Clancy’s own efforts to seek treatment.

For separated or divorcing parents, that complexity can create another problem: What do you do with an existing custody arrangement while a co-parent is in crisis?

Your Co-Parent Is Hospitalized. Who Has the Kids?

Suppose your former spouse is scheduled to have the children for the next five days. On the second day, they are admitted to a psychiatric hospital.

Who takes over?

The existing custody order, immediate needs of the children, availability of the other parent, and circumstances of the hospitalization can all become relevant. A grandparent or another relative may already be caring for the children.

A short-term change during hospitalization can also develop into a larger custody issue if the crisis continues or the parents disagree about when the previous schedule should resume.

Keep records of what actually happened. Dates of missed parenting time, communications between the parents, changes in who cared for the children, and specific safety concerns provide more useful information than general statements about the other parent’s mental health.

You Think Your Co-Parent Is in Crisis. They Say They’re Fine.

This can be one of the most frightening situations for a separated parent.

Your child is supposed to go to the other parent’s home, but something has changed. Your co-parent is sending messages that do not make sense, behaving erratically, talking about things that do not appear to be real, or showing other behavior that makes you question whether your child will be safe.

You may believe sending your child is dangerous while also having a custody order requiring the exchange.

Document what you personally observe. Preserve relevant texts, emails, voicemails, or other communications. Record specific dates and incidents rather than trying to diagnose your co-parent yourself.

If there is an immediate threat to a child, emergency intervention may be necessary. Courts also have procedures for requesting emergency or temporary custody orders, although the requirements vary by state.

The Clancy trial demonstrates why observable facts can matter so much. Attorneys on both sides have spent considerable time examining what Clancy said, what she searched online, what her husband and providers observed, what treatment she received, and how her behavior changed before the deaths.

In a custody case, the circumstances will be very different, but the same basic principle applies: specific evidence of what a parent is doing and how it affects the child is more useful than assigning the parent a diagnosis yourself.

Your Ex Says Your Mental Health History Makes You an Unsafe Parent

Now consider the issue from the other parent’s perspective.

Perhaps you experienced postpartum depression after your child was born. You were hospitalized during a severe episode. You have bipolar disorder. You experienced postpartum psychosis and received treatment.

Now you are divorcing, and your spouse is pointing to that history as a reason you should have less parenting time.

Family courts can consider a parent’s mental health when it affects parenting capacity, safety, or the child’s welfare. Evidence of treatment and current functioning can therefore become important. Depending on the case, that may include treatment history, compliance with recommendations, evaluations, a safety plan, testimony, or evidence showing how the parent currently cares for the child.

The intense attention on postpartum psychosis during the Clancy trial also makes an important point for family law: the name of a diagnosis cannot tell a court how a particular parent is functioning today.

Custody decisions require an individualized look at the parent, the child, and the circumstances in that family.

What Happens to Parenting Time During Treatment?

A parent receiving psychiatric treatment may need a temporary change in parenting time.

Depending on the severity of the situation, the child’s needs, and state law, an arrangement could involve a different parenting schedule, supervised parenting time, temporary primary care by the other parent, or conditions addressing a particular safety concern.

After hospitalization, another question arrives: When does the previous schedule resume?

Parents may have very different answers. One may believe discharge from the hospital means the regular schedule can start immediately. The other may want evidence of continued stability or a gradual transition.

Putting temporary agreements in writing and getting legal advice about whether court approval is necessary can prevent an emergency arrangement from becoming a new custody dispute.

The Crisis Has Passed. Can Custody Go Back to Normal?

The Clancy case has understandably focused attention on what can happen at the most extreme end of a psychiatric crisis. Most families dealing with parental mental health concerns will face a very different question: What happens after the parent gets better?

A parent may complete inpatient treatment, continue outpatient care, stabilize on medication, return to work, establish a consistent routine, and demonstrate that they can safely care for their child.

If parenting time was restricted during the crisis, the family may need to revisit that arrangement. Current functioning, treatment progress, compliance with court requirements, the child’s needs, and how parenting time has gone since the crisis can all become relevant.

A custody arrangement created during an acute psychiatric episode may need to change as the parent’s circumstances change.

What If the Crisis Happens While You Are Still Married?

A psychiatric crisis can also occur when a marriage is already ending.

Perhaps you and your spouse have discussed separation but nobody has filed for divorce. Then your spouse is hospitalized. Or you have a newborn and older children at home while your spouse’s behavior changes dramatically.

Who cares for the children? What happens when your spouse comes home? Do you need a temporary custody order? What if grandparents or other relatives have already stepped in?

If there is an immediate safety emergency, protecting the children takes priority. Once the immediate situation is addressed, a family law attorney can review the circumstances, existing parental rights, and whether temporary custody orders or other court intervention are appropriate.

Focus on What Is Happening With Your Child

The Lindsay Clancy trial involves extraordinarily serious allegations, and a jury will determine the criminal questions presented in her case. The national conversation surrounding the trial also shows how quickly mental health, parenting, treatment, and child safety can become intertwined.

For parents facing a custody issue, focus on what is happening in your own family. Is your child safe? What behavior have you personally observed? Is the parent receiving treatment? Can they currently meet the child’s needs? Has something changed since the custody order was entered? Has the situation improved since the original crisis?

Those are the facts that can give your attorney and the court a clearer picture of what your child needs now.

When a Mental Health Crisis Changes Your Parenting Situation

A serious mental health crisis can change a family’s routine overnight. One parent may suddenly become the children’s primary caregiver while also trying to understand a hospitalization, an existing custody order, and what needs to happen next.

As the Lindsay Clancy trial brings renewed attention to postpartum psychosis and gaps in recognizing and treating serious postpartum mental illness, it also serves as a reminder that families need somewhere to turn when a parent’s condition suddenly affects their ability to care for a child.

If your co-parent is experiencing a mental health crisis, you are concerned about your child’s safety during parenting time, or your own mental health history has become an issue in a custody case, the attorneys at Melone Hatley, P.C. — Your Partner in Divorce® can review the circumstances, explain the custody options available under your state’s law, and determine what legal steps may be appropriate.
