Do you have concerns that your child’s parent has issues with drugs or alcohol that may place your child at risk of harm while in their care?

Have allegations about drug and alcohol misuse been made against you?

If there are concerns about a parent’s use of drugs or alcohol, the Court may order testing to help determine whether the children may be exposed to any risk while in that parent’s care. In many cases, parties may also agree to undertake testing voluntarily to address concerns early and avoid unnecessary litigation.

There are easy ways to clear up the issue when one party makes allegations or drug or alcohol misuse and that is by way of a drug and alcohol test.

Drug and Alcohol Testing Options

There are various test options available and the most common testing methods are as follows:

Hair Follicle Testing

This allows for approximately 3 to 4 months of use to be detected. It can be an expensive test, however, provides valuable information to the parties and the Court of whether there has been any recent use and the level of use. There are requirements for hair length and for the hair not to be dyed as well. Typically head hair is used, however, other body hair can also be used for this test as long it is sufficient length.

Toenail Drug and Alcohol Testing

A relatively newer testing option is toenail drug and alcohol testing. It is about half the price of the hair follicle test and can test for a period of 12 months. Both these are positive benefits of opting for this testing option over hair follicle. The other benefit is that it is less evasive than having a section of your hair cut for the hair follicle test. Currently only a limited of places offer this testing.

Urine Testing

Urine testing is another commonly used method of testing, however it generally only detects recent substance use over a shorter period of time, depending on the substance involved.

CDT Testing for Alcohol Use

CDT (Carbohydrate Deficient Transferrin) testings are also common undertaken if there are concerns about alcohol use. This typically will indicate if there have been recent high levels of alcohol consumption.

Why would you undertake a drug or alcohol test Voluntarily?

In some situations, undertaking testing before Court Orders are made may assist in resolving concerns quickly and reducing conflict between the parties.

Voluntary testing may:

• assist with keeping the care arrangements out of Court if the issue can be resolved;
• Provide reassurance to the other parent regarding the child’s safety;
• Support a parent who is actively addressing substance-related concerns and seeking treatment; or
• Demonstrate a willingness to prioritise the best interest of the children.

Moving Forward With Clarity and Confidence

Taking proactive steps to address concerns about drug or alcohol use can make a significant difference in reducing conflict and ensuring the safety and wellbeing of children. Whether testing is undertaken voluntarily or through Court Orders, the results can provide clarity, support informed decision‑making, and help parents move forward with arrangements that prioritise their child’s best interests.

If you have concerns about the other parent, are facing allegations, or simply want guidance on the most appropriate testing option, seeking early legal advice can help you understand your rights, responsibilities, and the best pathway to a safe and workable parenting arrangement.
