Can a Parent Lose Custody Because of Drug or Alcohol Use?

Concerns about drug or alcohol use sometimes arise in parenting disputes after separation. When this happens, many parents worry about how substance use may affect parenting arrangements or whether a parent could lose time with their child.

In family law proceedings, the court does not automatically remove a parent from a child’s life because of drug or alcohol use. Instead, the court focuses on whether the substance use creates a risk to the child’s safety or wellbeing.

The court’s primary consideration is always the best interests of the child.

How Courts Assess Drug or Alcohol Use

When substance use is raised in parenting proceedings, the court will consider a range of factors, including:

• Whether the substance use affects the parent’s ability to safely care for the child
• Whether the child has been exposed to unsafe behaviour
• Whether the substance use is occasional, historic, or ongoing
• Whether the parent has sought treatment or counselling
• Whether safeguards can reduce potential risk

The existence of substance use alone does not determine parenting arrangements. The key question is whether the child is placed at risk.

Possible Parenting Outcomes

Where substance use concerns exist, the court may consider different parenting arrangements depending on the level of risk identified.

These may include:

Drug or Alcohol Testing

Courts may order testing to determine whether substance use is ongoing.

This can include:

• Urine drug testing
• Hair follicle testing
• Alcohol biomarker testing such as CDT or PEth

Testing can provide objective evidence where allegations are disputed.

Supervised Time

Where concerns exist but the court wishes to preserve the parent-child relationship, the court may order supervised time.

This allows the child to spend time with the parent while an independent person monitors the interaction.

Supervision may be temporary while a parent addresses substance use concerns.

Limited or Structured Parenting Time

In some situations, the court may order structured arrangements such as:

• Daytime contact only
• Shorter visits

These arrangements can sometimes progress over time if concerns are addressed.

When Substance Use May Have Greater Impact

In more serious cases, parenting arrangements may be significantly affected.

This may occur where there is evidence of:

• Chronic substance dependency
• Unsafe behaviour while caring for the child
•Repeated breaches of court orders
• Refusal to participate in testing or treatment

Even in these circumstances, courts will still consider whether there are safe ways for the child to maintain a relationship with the parent.

Evidence the Court May Consider

Where allegations of drug or alcohol misuse are raised, the court may consider a range of evidence including:

• Drug or alcohol testing results
• Police or hospital records
• Text messages or admissions
• Witness statements and Affidavit material
• Counselling or rehabilitation records

Each case will depend on the reliability and strength of the evidence available.

Responding to Allegations of Substance Use

Allegations of drug or alcohol misuse can be serious in parenting proceedings. It is important that these issues are addressed carefully and with appropriate evidence.

Legal advice can assist parents to understand:

• How courts assess substance use concerns
• What testing may be ordered
• How to respond to allegations
• How parenting arrangements may be structured

Early advice can often help ensure these issues are addressed constructively and with the child’s wellbeing at the centre of the process.
