My Ex Has Mental Health Problems and I'm Worried About the Kids. What Can I Do in Ohio?

Reviewed by Stephanie Green · Managing Partner & Co-Founder · Last updated September 6, 2026

This is one of the hardest calls we take, because the person on the other end is usually torn. They are worried about their children. They may also still care about their co-parent. And they do not want to be the person who weaponizes a diagnosis in a custody case.

So let's start with the thing that needs saying first: having a mental health condition does not make someone a bad parent, and Ohio courts do not treat it that way.

Then let's get to the part you are actually asking about: what happens when the condition is not being managed, or the other parent will not acknowledge it at all, and you can see it affecting the children.

A diagnosis alone is not a custody problem

Think about it the way you would think about diabetes, high blood pressure, or any other chronic physical condition. Millions of parents manage those every day, and nobody suggests they should lose time with their children because of it. Mental health works the same way in an Ohio courtroom. A parent who is in treatment, taking medication as prescribed, and functioning well is not going to be punished or handed lesser rights because of a diagnosis on a chart.

Ohio's custody statute does list "the mental and physical health of all persons involved" as one of the best-interest factors a judge must consider. Notice the wording: all persons involved. That includes you. Courts look at this factor the way they look at any other: does it actually affect the child? The full list of factors is in our guide to Ohio child custody laws.

If you walk into court with the argument "my ex has anxiety, therefore I should have custody," you will lose that argument, and you may lose credibility with the judge along the way.

When it becomes a real issue

The conversation changes when the condition is not being managed, or when there are serious warning signs and the other parent refuses to address them. Ohio law gives you tools for that.

The question a court asks is not "does this parent have a mental health condition?" It is "is this parent's current health affecting their ability to safely and appropriately parent?" Things like:

• Episodes that leave the parent unable to supervise or care for the child.
• Erratic or frightening behavior around the child.
• Missed medication or abandoned treatment followed by a clear decline.
• Substance use layered on top of the condition.
• Statements or behavior suggesting the parent is a danger to themselves or others.
• Repeatedly failing to show up, or showing up in no condition to parent.

All of these are about behavior and its effect on the child, not about a label. That is what you will need to show, and it is why documentation matters so much.

First question: how dangerous is the situation right now?

Everything that follows depends on your honest answer to one question: is my child in immediate danger, or am I concerned about a pattern? Those two situations lead to very different legal paths.

If the child is in immediate danger

Ohio courts can act quickly, sometimes the same day. Which motion you file depends on your current custody status:

• If you are the non-custodial parent, or a third party such as a grandparent or other relative, you may file an ex parte motion for emergency custody. "Ex parte" means the court can issue a temporary order based on your sworn affidavit before the other parent responds. A full hearing follows quickly, usually within days or a couple of weeks.
• If you have shared parenting or sole custody and the danger arises during the other parent's time, you may file an expedited motion to suspend or restrict parenting time.

The bar here is high, and it should be. You must show a real risk of imminent harm, not generalized worry. A parent having a hard month is not an emergency. A parent in an active crisis who cannot safely supervise a child is. Filing an emergency motion without emergency facts is one of the fastest ways to damage your standing with a judge, so if you are unsure whether your situation qualifies, that is exactly the moment to talk to an attorney before you file. Our statewide guide to emergency custody in Ohio explains what a court needs to see.

If it is a pattern, not an emergency

If you believe the other parent is not in a place to safely exercise their parenting time, or is not able to make sound decisions for the children, the path is a motion to modify. What you are asking to modify determines the standard:

• Modifying parenting time — the schedule, conditions on the time, supervision, exchanges — requires showing the change is in the child's best interest. That is it. No threshold showing of changed circumstances.
• Modifying custody — who is the legal custodian and residential parent — is a heavier lift. If one parent has sole custody and you want to change that, Ohio requires proof of a substantial change in circumstances since the last order, plus a showing that the change is in the child's best interest and that its benefits outweigh the harm of disruption. A significant, documented decline that is affecting the child can qualify, but the key word is documented. If you have shared parenting and are asking the court to terminate it and name you sole custodian, the focus is the child's best interest, but you still need to show what changed and why the arrangement no longer works.

Most of these cases land in the parenting time category, at least at first: supervision, conditions, or a schedule adjustment while the other parent gets stable. Custody changes tend to come when the pattern is severe or long-running. See post-decree modifications in Ohio for how the motion itself works.

The tools Ohio courts can use

Whether you are in a first-time custody case or coming back to modify an existing order, these are the main tools. You can request them, and the court can also order them on its own.

A court-ordered mental health evaluation

Ohio law gives the court power to order either or both parents to undergo a psychological or psychiatric evaluation and to have the results provided to the court. This is separate from any treatment the parent may be in. It is an assessment by a neutral professional for the purpose of the case, and it looks at current functioning and parenting capacity, not just whether a diagnosis exists.

Two things to be ready for before you ask:

1. The court can order you to do it too. Judges frequently order both parents to complete whatever the requesting parent asked for, whether that is an evaluation, drug testing, or alcohol monitoring. If you are not prepared to sit for the same evaluation you are asking your co-parent to complete, think carefully before requesting it. If you are prepared, that willingness tends to help you.
2. You may be ordered to pay for it. Courts sometimes assign the cost to the requesting party, at least up front. Costs vary widely by provider and scope, and are often split or reallocated later, but budget for the possibility.

A guardian ad litem (GAL)

A guardian ad litem is a person appointed by the court, usually an attorney, whose only job in the case is to investigate and advocate for the best interest of the child. The GAL does not work for you and does not work for your co-parent. Either parent can ask for one, or the judge can appoint one without being asked.

What a GAL actually does:

• Meets with each parent, usually more than once.
• Speaks with the child privately, in an age-appropriate way.
• Interviews teachers, school staff, counselors, doctors, family members, and others who know the child.
• Reviews records: school, medical, counseling, court, police.
• Conducts home visits, sometimes unannounced.
• Asks both parents for information and documents.
• Can ask the court to order a parent to complete an evaluation, drug or alcohol testing, or other assessments.
• Can make recommendations about temporary orders while the case is pending.

At the end of the investigation, which can take several months, the GAL files a written report and recommendation with the court and the parties about what custody and parenting time arrangement they believe serves the child. Ohio's rules require the report to be filed before trial so both sides can review it.

Courts often give a GAL's recommendation significant weight because it comes from a neutral third party focused solely on the child. But it is not automatic. The GAL is a witness like any other: you or your attorney can question the GAL at hearing or trial about the investigation, what they did and did not do, who they spoke to, and how they reached their conclusions. A thin investigation, or a recommendation that ignores key facts, can be challenged.

GALs also cost money. Courts typically require one or both parents to deposit a retainer toward the GAL's fees, which vary by county.

Supervised parenting time

If the concern is safety during the other parent's time, but cutting off contact is not warranted or is not in the child's interest, the court can order supervised parenting time. The parent still sees the child, but only in the presence of an approved third-party supervisor — often a relative both parents trust — or at a supervised visitation center.

Ohio courts have broad authority to set any parenting time terms that serve the child's best interest, and supervised time is one of the most common ways they handle these concerns. Supervised orders can include step-up provisions that let a parent gradually earn back unsupervised time by meeting specific conditions, for example:

• A set period of consistent, incident-free supervised visits.
• Completing a treatment program or maintaining consistent counseling.
• A recommendation from the parent's treating doctor or therapist.
• A follow-up evaluation with favorable results.
• A defined number of consecutive negative drug or alcohol screens.

Step-up plans are often the most workable outcome. They protect the child now, give the struggling parent a clear path forward, and avoid another round of litigation every time something changes.

Subpoenas for medical and mental health records

You can also ask the court's help getting records. A subpoena is a court-issued demand that a person, provider, or facility produce documents or testify. In a custody case, subpoenas can reach counseling, psychiatric, medication, and hospital records.

There are real limits, and this is where people get tripped up.

Scope. A subpoena has to be specific and tied to the issues actually in the case. You cannot demand a person's entire mental health history going back thirty years; a request like that is overbroad and will be quashed. A request for treatment records from the last two years, related to the condition you have raised, is the kind of scope courts will entertain.

Privilege. Ohio law protects communications between a patient and their physician, psychologist, counselor, or social worker. That privilege is not absolute in a custody case, but it is not automatically waived either. Courts weigh the parent's privacy against the child's best interest, and where a parent's health is directly at issue, judges can order records produced. Often they will limit the time frame, restrict the records to the relevant condition, or review them privately — called in camera review — before deciding what the other side sees. A parent who puts their own health in play, for example by testifying that they are in treatment and doing well, generally cannot then block the records that would prove or disprove it.

HIPAA. People often assume HIPAA makes medical records untouchable. It does not. HIPAA is a federal privacy rule governing how providers handle health information, and it specifically allows providers to release records in response to a court order, or to a subpoena where the patient has been given notice and a chance to object, or a protective order is in place. HIPAA controls the process, not whether records can ever be obtained. The bigger obstacle in Ohio cases is usually the state privilege rules above.

It cuts both ways. Sit with this before you send a subpoena. If you ask the court to open your co-parent's medical history, expect your own to be fair game. Your counseling records, prescriptions, and hospital visits are reachable by the same rules. That does not mean you should not do it. It means you should know what is in your own file before you go looking in someone else's.

A practical note: a court-ordered evaluation often yields more useful information than a records subpoena, because it is current, focused on parenting capacity, and created for the court rather than pulled from a treatment file never meant to be read by a judge.

What to document, and how to talk about it

Because everything here turns on behavior and effect on the child rather than diagnosis, your record matters more than your opinion.

• Keep a factual log. Dates, what happened, who was present, what the child said or did afterward. "Tuesday 3/14, arrived for exchange at 6:10 pm, was slurring words and became agitated in the driveway when I asked if he had eaten; the children were in the car and crying" is useful. A general characterization is not.
• Save communications. Texts, emails, voicemails, and co-parenting app messages — especially anything showing concerning statements, missed exchanges, or refusal to engage in treatment.
• Note objective sources. Police reports, school incident reports, hospital visits you know about, statements from teachers or coaches. Third-party observations carry far more weight than yours alone.
• Do not diagnose. You are not your co-parent's doctor, and asserting a diagnosis that has never been made will hurt you. Describe what you saw and let the professionals draw conclusions.
• Do not interrogate your child. Age-appropriate, unprompted comments belong in your log. Questioning or coaching a child is something judges and GALs recognize quickly, and it damages your credibility.
• Stay steady yourself. Your health is one of the "all persons involved" too. Keep your own appointments, keep your conduct clean at exchanges, and do not respond to provocation in writing.

If the other parent is simply not exercising their time rather than exercising it unsafely, that is a different problem with different fixes — see what to do when your co-parent hands their parenting time to someone else. And where an existing order is being violated outright, a contempt motion is the enforcement tool.

The reality under Ohio law, in one place

A diagnosis is not a custody problem. A managed mental health condition, like a managed physical one, does not cost a parent time or rights.

Conditions that are untreated and affecting the child are. The court looks at behavior and its impact on the child, and the health of all persons involved is a best-interest factor.

How dangerous the situation is determines your path. Imminent danger means emergency motions. A concerning pattern means a motion to modify.

Parenting time is easier to change than custody. Parenting time modifications require a best-interest showing. Changing who has custody requires a substantial change in circumstances.

The court has real tools. Court-ordered evaluations, a guardian ad litem, supervised parenting time with step-up provisions, and subpoenas for relevant records.

Everything you ask for can be asked of you. Evaluations, testing, and record subpoenas all run in both directions. Be ready for that before you request them.

Documentation beats diagnosis. Judges and GALs act on specific, dated, verifiable facts about behavior and its effect on the child.

Frequently asked questions

Can a parent with a mental health condition get custody in Ohio?

Yes. A diagnosis alone does not disqualify a parent from custody or parenting time. Ohio courts consider the mental and physical health of everyone involved as one best-interest factor, and what matters is whether the condition is affecting that parent's ability to care for the child.

How do I show that my co-parent's mental health is affecting the children?

Through documented behavior and its effect on the child, not through a diagnosis. Keep a dated log of specific incidents, save communications, and gather third-party sources such as school or police reports. The court can also order an evaluation or appoint a guardian ad litem to investigate.

Can the court order a psychological evaluation in an Ohio custody case?

Yes. Ohio courts can order one or both parents to complete a psychological or psychiatric evaluation and have the results provided to the court. Be prepared for the court to order you to complete one as well, and possibly to pay for it.

What does a guardian ad litem do in Ohio?

A GAL is appointed by the court to investigate and advocate solely for the child's best interest. They interview both parents and the child, speak with teachers and other adults in the child's life, review records, conduct home visits, and file a written recommendation the court gives significant weight to — though either parent may question the GAL at hearing.

Can I get emergency custody because of my co-parent's mental health?

Only if the child faces a real risk of imminent harm. A diagnosis or a rough stretch is not enough. If the danger is immediate, a non-custodial parent or third party may file an ex parte motion for emergency custody; a parent with shared parenting or sole custody may file an expedited motion to suspend parenting time.

What is supervised parenting time?

Parenting time that takes place only in the presence of an approved supervisor or at a supervised visitation center. Ohio courts often pair it with step-up provisions letting a parent earn back unsupervised time by meeting conditions such as consistent treatment or clean screens.

Can I subpoena my co-parent's mental health records in a custody case?

Sometimes, within limits. The request must be specific and tied to the issues in the case; requests for an entire history are overbroad. Ohio's patient privilege applies but is not absolute where a parent's health is directly at issue, and courts may limit scope or review records privately first. Your own records are reachable by the same rules.

Does HIPAA prevent medical records from being used in a custody case?

No. HIPAA permits providers to release records in response to a court order, or to a subpoena with proper notice or a protective order. HIPAA governs the process for release, not whether records can ever be obtained. Ohio's privilege rules are usually the more significant limit.

Do I need to show a change in circumstances to modify custody in Ohio?

To change which parent is the sole legal custodian, yes: a substantial change in circumstances since the last order, plus a best-interest showing. Modifying parenting time, including adding supervision or conditions, requires only that the change be in the child's best interest.
