What to do if a Co-Parent is Abusing Drugs

Quick Answer

If you suspect your co-parent is abusing drugs in California, document all evidence immediately and consult a family law attorney. California Family Code allows you to file for emergency custody modifications or supervised visitation to protect your child. You’ll need proof such as toxicology reports, witness testimony, or evidence of substance abuse. The courts prioritize the child’s best interests and safety above parental rights when substance abuse is involved.

Key Takeaways

• California courts can modify custody arrangements when substance abuse threatens a child’s safety or well-being.
• You must provide evidence, not just allegations, to prove that substance abuse poses a risk to your child.
• Evidence can include drug test results, witness testimony, police reports, and documentation of erratic behavior.r
• Options include requesting supervised visitation, custody modifications, or emergency protective orders.
• Even parents with substance abuse issues may retain visitation rights if they complete treatment and demonstrate sobriety.

Understanding California Law on Substance Abuse and Child Custody

California family law recognizes that both parents generally have the right to spend time with their minor children following a divorce or separation. However, when a parent’s behavior, including drug or alcohol abuse, poses a risk to the child’s safety, physical health, or emotional well-being, the courts will intervene to protect the child.

An “unfit parent” determination under California law is not based on a judge’s personal feelings or assumptions. Instead, it is grounded in specific behaviors and conditions that could endanger the child. These include physical abuse, sexual abuse, neglect, and substance abuse. A parent’s drug addiction can compromise their ability to provide consistent, secure, and loving care, making this a serious concern in custody and visitation cases.

With over 20 years of experience in family law, attorney Wail Sarieh and the team at Sarieh Family Law have guided countless Orange County families through these difficult situations. We understand the fear and uncertainty you face when you suspect your child may be in danger. Our approach combines legal expertise with compassion, focusing on protecting your child while navigating California’s complex family law system.

Relevant California Statutes

California Family Code Section 3011 outlines the factors courts must consider when determining the best interests of the child in custody cases. This includes:

• The health, safety, and welfare of the child
• Any history of abuse by one parent against the child or the other parent
• The nature and amount of contact with both parents
• The habitual or continual illegal use of controlled substances or alcohol by either parent

California Family Code Section 3020 establishes that children have the right to frequent and continuing contact with both parents, but only when this contact is in the child’s best interests. Substance abuse can directly contradict this best interest standard.

California Family Code Section 3041 specifically addresses situations where the court finds that a parent habitually or continually uses controlled substances or alcohol. In such cases, the court may order that parent to abstain from use of the substances while caring for the child and for a reasonable period before exercising custody or visitation.

California Family Code Section 3064 allows courts to issue emergency orders when necessary to protect the child from immediate harm.

What Constitutes “Unfit” Due to Substance Abuse

California courts look to the mental and physical health provisions of the Family Code when evaluating whether substance abuse renders a parent unfit. The key question is not simply whether the parent uses drugs or alcohol, but whether this use creates a substantial risk of harm to the child.

Factors the court considers include:

• Whether the parent uses drugs or alcohol in the child’s presence
• Whether substance abuse impairs the parent’s judgment or ability to supervise the child
• Whether the parent’s addiction leads to neglect of the child’s basic needs
• Whether the parent engages in illegal activity to obtain drugs
• Whether the parent exposes the child to dangerous people or environments related to drug use
• Whether the parent drives under the influence with the child in the vehicle

The court may deny unsupervised visitation, place the parent on supervised visitation, or, in severe cases, deny custody and visitation rights entirely until the parent demonstrates sustained sobriety and rehabilitation.

Recognizing Warning Signs

While you may have suspicions about your co-parent’s drug use, it’s important to recognize the warning signs that may indicate a substance abuse problem affecting your child’s safety.

Physical and Behavioral Signs

• Dramatic changes in appearance or personal hygiene
• Unexplained weight loss or gain
• Bloodshot or glazed eyes
• Slurred speech or impaired coordination
• Erratic sleep patterns (sleeping too much or too little)
• Unusual odors on breath, body, or clothing
• Frequent illness or unexplained injuries

Parenting and Behavioral Red Flags

• Missing scheduled visitation without valid explanations
• Showing up late or unprepared for parenting time
• Inability to maintain a safe and clean home environment
• Failure to provide adequate food, supervision, or care during their parenting time
• Emotional volatility or mood swings around the child
• Secretive or defensive behavior
• Financial problems despite adequate income
• Association with individuals known to use drugs

Child’s Reactions and Reports

Pay attention to what your child tells you about their time with the other parent. While you should never coach your child or put them in the middle of adult issues, legitimate concerns include:

• A child expressing fear or reluctance to visit the other parent
• Child reporting seeing drug use or paraphernalia
• Child describing neglectful situations (being left alone, no food provided)
• Child showing signs of anxiety, stress, or behavioral changes after visits
• Child reporting being driven by an impaired parent

Steps To Take If You Suspect Substance Abuse

If you believe your co-parent has a drug or alcohol problem that could endanger your child, taking the right steps is crucial. Acting rashly or emotionally can harm your case, while failing to act can put your child at risk.

1. Document Everything Immediately

Begin creating a detailed record of your concerns immediately. This documentation will become critical evidence if you need to seek court intervention.

What to document:

• Dates, times, and specific observations of concerning behavior
• Instances where the other parent appeared impaired during exchanges or visits
• Missed or late pickups/dropoffs with explanations given
• Text messages, emails, or voicemails that suggest substance abuse
• Photos of unsafe conditions at the other parent’s home
• Names and contact information of witnesses who have observed concerning behavior
• Records of your child’s statements (written contemporaneously, without leading questions)
• Medical or school records showing changes in the child’s behavior
• Police reports if law enforcement was involved
• Any admission of drug use by the other parent

Documentation best practices:

• Record observations as soon as possible after they occur
• Be specific and objective (describe what you saw, heard, or smelled)
• Avoid inflammatory language or assumptions
• Include context (date, time, location, who was present)
• Keep physical evidence secure (photos, messages) in multiple locations
• Never falsify or exaggerate information

2. Prioritize Your Child’s Immediate Safety

If you believe your child is in immediate danger, take action to protect them:

• If the other parent arrives to pick up your child and appears intoxicated or under the influence, refuse to release the child and call law enforcement
• If you discover your child is with an impaired parent, contact law enforcement immediately
• Never put yourself in danger; call 911 if the situation escalates
• If the other parent is driving impaired with your child, call 911 and report the vehicle, license plate, and direction of travel.

While withholding a child from court-ordered visitation can have legal consequences, California courts recognize that a parent has the right and duty to protect their child from immediate harm. Document any instances where you kept the child due to safety concerns and inform your attorney immediately.

3. Consult With a Family Law Attorney

Before taking legal action, consult with an experienced family law attorney who understands California custody law and substance abuse issues. An attorney can:

• Evaluate the strength of your evidence
• Advise you on the best legal strategy for your situation
• Help you avoid actions that could harm your credibility with the court
• Prepare and file appropriate motions with the court
• Request drug testing or other evidence gathering
• Represent you at hearings and ensure your child’s interests are protected

At Sarieh Family Law, we provide compassionate guidance while building strong cases to protect children from substance-abusing parents. With decades of experience in Orange County Superior Court, we know how local judges approach these sensitive cases.

4. Request Drug Testing and Gather Evidence

California courts have the authority to order drug and alcohol testing when substance abuse is alleged in a custody case. Your attorney can request the court to order testing through a Request for Order (RFO).

Types of drug testing:

• Urinalysis: Detects recent drug use (typically 1-7 days, depending on the substance)
• Hair follicle testing: Shows drug use over a longer period (up to 90 days)
• Blood testing: Most accurate for detecting current impairment, but invasive
• Breathalyzer: Tests for alcohol use
• Continuous alcohol monitoring (SCRAM bracelet): Monitors alcohol consumption 24/7

The court may order random testing, scheduled testing before and after visits, or ongoing monitoring. The parent subject to testing typically bears the cost.

Witness testimony can be powerful evidence when proving substance abuse. Potential witnesses include:

• Family members who have observed drug use or impairment
• Neighbors who have witnessed concerning behavior
• Childcare providers or teachers who have concerns
• Friends of the other parent who have knowledge of their drug use
• Police officers who responded to drug-related incidents
• Medical professionals who have treated the parent for addiction

Your attorney will determine which witnesses to call and how to present their testimony most effectively.

5. Consider Additional Investigation

In some cases, hiring a licensed private investigator can help gather evidence that would otherwise be difficult to obtain. Investigators can document the other parent’s activities and associations, photograph or video evidence of drug use or impaired behavior, locate witnesses, conduct background checks, and verify information about the other parent’s living situation.

Private investigators must operate within legal boundaries. Your attorney can recommend reputable investigators who understand California law and family court procedures.

Legal Options for Protecting Your Child

California law provides several legal mechanisms to protect children when a parent’s substance abuse creates risk.

Modifying an Existing Custody Order

If you have an existing custody order, you can file a Request for Order (RFO) to modify custody or visitation based on changed circumstances. Substance abuse that has developed or worsened since the original order qualifies as a significant change in circumstances.

To modify custody, you must prove:

• A substantial change in circumstances has occurred since the last custody order
• The modification is in the child’s best interests
• The other parent’s substance abuse creates a risk to the child

The court may modify the custody order to:

• Transfer primary physical custody to you
• Reduce or eliminate the other parent’s parenting time
• Require supervised visitation
• Impose conditions on the other parent’s visitation (drug testing, sobriety requirements)
• Order the other parent to complete substance abuse treatment

Requesting Supervised Visitation

Supervised visitation allows a parent to spend time with their child while a neutral third party monitors the visit to ensure the child’s safety. California courts frequently order supervised visitation when substance abuse is a concern, but terminating all contact with the parent is not warranted.

Levels of supervision:

• Professional supervision: A trained professional supervisor oversees visits at a designated facility
• Non-professional supervision: A family member, friend, or other responsible adult approved by the court supervises visits
• Monitored exchange: Visitation itself is unsupervised, but exchanges occur in a supervised setting or with professional assistance

The court’s order will specify who may supervise visits, where visits must occur, duration and frequency of visits, any prohibited behaviors (use of alcohol/drugs before or during visits), and conditions for transitioning to unsupervised visits.

The parent subject to supervised visitation typically pays for professional supervision services.

Seeking Emergency Orders

When immediate danger exists, you can request emergency or temporary emergency orders without waiting for a full hearing. California Family Code Section 3064 allows courts to issue emergency orders when necessary to protect the child from immediate harm.

Emergency orders may include:

• Temporary suspension of visitation
• Immediate transfer of custody
• Requirement for supervised visitation
• Restraining orders preventing the parent from contact while under the influence

To obtain emergency orders, you must demonstrate imminent harm to the child. Evidence might include recent police reports of drug use in the child’s presence, medical records showing the child was harmed due to neglect, credible threats or dangerous behavior by the impaired parent, or documentation that the parent is currently incarcerated on drug-related charges.

Emergency orders are temporary and remain in effect only until a full hearing can be scheduled (typically within 21 days).

Filing for a Restraining Order

In cases where the substance-abusing parent has been violent, threatening, or poses an immediate danger, you may petition for a Domestic Violence Restraining Order under California Family Code Section 6200. This can include provisions protecting the child, such as:

• No contact orders
• Stay-away orders from the child’s school or home
• Temporary custody to the protected parent
• Suspension of visitation or requirement for supervised visitation

The Court Process: What To Expect

Understanding how California family courts handle substance abuse cases can help you prepare for what lies ahead.

Filing the Request for Order

Your attorney will prepare and file a Request for Order (Form FL-300) with the Orange County Superior Court. The RFO must specify the changes you’re seeking (modified custody, supervised visitation, drug testing), provide a factual basis for your request, include supporting declarations under penalty of perjury, and attach relevant evidence.

You’ll also file an Income and Expense Declaration (Form FL-150) if requesting changes to child support.

Service and Response

The other parent must be properly served with copies of all documents you file. The other parent has the right to file a responsive declaration contesting your allegations. They may deny the substance abuse allegations, admit past substance abuse but claim current sobriety, present evidence of treatment completion or ongoing participation in recovery programs, or argue that their substance use does not impair their parenting.

Mediation

Orange County Superior Court may require parents to attend mediation through Family Court Services before a hearing on custody issues. At mediation, a court mediator meets with both parents (separately if there’s domestic violence), parents discuss their concerns and proposed solutions, and the mediator may make recommendations to the court. You must attend even if you don’t expect to reach an agreement.

The Court Hearing

If the case proceeds to a hearing, both sides will present evidence and testimony. The hearing process typically includes opening statements, evidence presentation (documents, test results, police reports, photos), witness testimony under oath with cross-examination, and, in some cases, the judge may interview the child in chambers.

The judge’s decision will be based on the evidence presented and the child’s best interests. California family court judges have broad discretion in custody cases.

Possible outcomes:

• Order drug testing (random or scheduled)
• Require substance abuse treatment or counseling
• Order supervised visitation
• Modify custody to reduce or eliminate the other parent’s parenting time
• Maintain current arrangements but add conditions (sobriety requirements)
• Order both parents to participate in co-parenting counseling
• Continue the matter for further evidence or evaluations

When the Substance-Abusing Parent Seeks Recovery

California courts recognize that addiction is a treatable condition. A parent with a substance abuse problem is not automatically barred from custody or visitation permanently. If the other parent takes steps toward recovery, the court will consider this in future custody decisions.

Evidence of Recovery

To demonstrate recovery and potentially restore or expand parenting time, the substance-abusing parent may present:

• Completion certificates from inpatient or outpatient treatment programs
• Attendance records from support groups (AA, NA, SMART Recovery)
• Clean drug test results over an extended period (typically 6 months to 1 year)
• Letters from counselors or sponsors attesting to their recovery efforts
• Employment stability and safe housing
• Participation in parenting classes
• Compliance with previous court orders

Gradual Restoration of Parenting Time

Courts typically take a gradual approach to restoring parenting time for recovering parents. Supervised visitation continues while the parent participates in treatment. As the parent demonstrates sustained sobriety, supervision may transition from professional to non-professional. After an extended clean time, brief unsupervised visits may begin. Unsupervised visits gradually increase in duration and frequency. Overnight visits may be permitted after demonstrated stability. Eventually, standard parenting schedules may be restored.

This process can take many months or even years. Throughout, the court’s focus remains on protecting the child while encouraging parental rehabilitation.

Real-World Examples

Understanding how these cases unfold in practice can help you know what to expect.

Example 1: Prescription Drug Abuse

Situation: Maria suspects her ex-husband Carlos is abusing prescription pain medication. Their 8-year-old daughter mentioned that “Daddy sleeps a lot” during her visits and that there were “lots of pill bottles” in the bathroom. Maria noticed Carlos seemed drowsy and unsteady during a recent child exchange.

Actions Taken: Maria documented the dates and details of her observations and her daughter’s statements. She consulted with a family law attorney. Her attorney filed an RFO requesting drug testing and supervised visitation. The court ordered Carlos to undergo hair follicle testing and scheduled a hearing.

Outcome: The drug test came back positive for opioids at levels inconsistent with prescribed use. The court ordered supervised visitation and required Carlos to complete a substance abuse treatment program. After six months of clean tests and completed treatment, the court allowed unsupervised day visits. After another six months of sobriety, overnight visits resumed.

Example 2: Methamphetamine Use with Immediate Danger

Situation: Linda received a frantic call from her 13-year-old daughter while the child was at her father Ron’s apartment for the weekend. The daughter reported that Ron was “acting crazy,” the apartment was trashed, and there were “scary people” there. Linda could hear yelling in the background.

Actions Taken: Linda immediately called 911 and reported her daughter’s location and the situation. Police responded and found Ron under the influence of methamphetamine with the child present. Linda picked up her daughter from the police station. The following business day, Linda’s attorney filed an emergency RFO requesting immediate suspension of Ron’s visitation.

Outcome: Based on the police report and the imminent danger, the court issued an emergency order suspending Ron’s visitation. At the subsequent hearing three weeks later, the court maintained the suspension and ordered that Ron could only have supervised visits if he completed an inpatient drug treatment program and demonstrated 12 months of sobriety through random drug testing.

Frequently Asked Questions

Can I stop my co-parent’s visitation if I suspect drug use without a court order?

While you have a duty to protect your child from immediate harm, withholding visitation without a court order can have legal consequences. If you believe your child is in immediate danger, call law enforcement and document the situation. Then contact a family law attorney immediately to seek emergency court orders. If possible, communicate your safety concerns to the other parent in writing and suggest alternative arrangements while you seek court intervention.

What if my ex accuses me of drug use to gain custody?

False accusations of substance abuse do occur in custody disputes. If you’re falsely accused, the best defense is evidence. Voluntarily submit to drug testing to prove your sobriety. Gather witnesses who can testify to your appropriate parenting and lack of substance abuse. Maintain documentation showing you’ve been a responsible, involved parent. An experienced family law attorney can help you defend against false allegations and potentially seek sanctions against the other parent for making frivolous claims.

How long does the custody modification process take?

The timeline varies depending on court schedules, case complexity, and whether emergency orders are needed. Emergency orders can be obtained within days. Standard RFOs typically result in a hearing within 4-8 weeks after filing, though delays are common. If the case requires extensive evidence, evaluations, or multiple hearings, the process can take several months. Working with an experienced attorney can help expedite the process.

Will my child have to testify in court?

California courts prefer not to have young children testify in open court due to the emotional trauma this can cause. However, judges may interview children in chambers (in the judge’s private office) without the parents present. This typically occurs only with children aged 14 or older, though younger children may be interviewed in some cases. The judge will ask age-appropriate questions about the child’s experiences and preferences. Children are never forced to testify against a parent.

What if the other parent refuses to take court-ordered drug tests?

Refusal to comply with court-ordered drug testing is a serious matter. The court can hold the non-compliant parent in contempt, which may result in sanctions, fines, or even jail time. Additionally, courts may draw negative inferences from the refusal to test, essentially treating the refusal as evidence of substance abuse. This can result in modification of custody or visitation even without a positive drug test.

Can grandparents get involved if both parents have substance abuse issues?

Yes. If both parents are unable to care for the child due to substance abuse, grandparents or other relatives can petition for custody under California Family Code Section 3040. The court recognizes that placement with relatives is generally preferable to foster care. Grandparents may need to demonstrate that neither parent can provide safe care and that placement with them serves the child’s best interests.

How much does it cost to modify custody due to substance abuse concerns?

Costs vary significantly depending on case complexity. Simple cases where the other parent doesn’t contest the modification may cost $3,000 to $7,000 in attorney fees. Contested cases requiring multiple hearings, extensive evidence gathering, expert witnesses, and trial can cost $15,000 to $30,000 or more. However, your child’s safety is priceless, and many attorneys, including Sarieh Family Law, offer payment plans to make legal representation accessible.

What happens if my co-parent goes to rehab?

A parent entering substance abuse treatment is generally viewed positively by California courts, as it demonstrates recognition of the problem and willingness to change. However, the court’s primary concern remains the child’s safety. The court will likely maintain protective orders (supervised visitation, drug testing) while the parent is in treatment and during early recovery. Successful completion of treatment and sustained sobriety can lead to gradual restoration of parenting time.

Protecting Your Child While Maintaining Compassion

Addressing a co-parent’s substance abuse is one of the most difficult challenges in family law. It’s natural to feel anger, fear, and frustration. However, approaching the situation with a focus on your child’s safety and well-being, rather than punishing the other parent, will serve you better in court and ultimately benefit your child.

Children benefit from having relationships with both parents when those relationships are safe and healthy. California courts recognize this. If the other parent is willing to address their substance abuse and can demonstrate sustained recovery, allowing them to maintain a relationship with your child, appropriately supervised at first, can be in your child’s best interests.

At the same time, you must be your child’s advocate. No one knows your child better than you do. Trust your instincts when you sense danger, but also work with experienced professionals who can guide you through the legal process effectively.
