Step-Parent Adoption Western Australia: Requirements, Process, and Alternatives
Step-parent adoption in Western Australia is legally available, but it comes with a significant caveat that surprises many families: Western Australian law often actively discourages it.
That is not a bureaucratic quirk. It reflects a considered legislative position under the Adoption Act 1994 (WA) — that adoption should only be used when no lesser order can adequately serve the child's needs. Before spending months or years pursuing a step-parent adoption, it is worth understanding exactly what the law requires and why a parenting order may serve your family better in most situations.
What Step-Parent Adoption Actually Does
Step-parent adoption under the Adoption Act 1994 (WA) permanently transfers full parental rights and responsibilities from the other biological parent to the step-parent. The child takes the adoptive family's surname, receives the same inheritance rights as a biological child, and legally becomes the child of both the resident parent and the step-parent.
The catch: adoption irrevocably severs the legal relationship between the child and their other biological parent — and the entire extended biological family on that side. Grandparents, aunts, uncles, siblings from that branch of the family lose their legal standing with the child. For a child who has any existing connection to that family, this is a permanent change that cannot be undone.
This is why the Family Court of Western Australia applies what is called the "preferable order" test to every step-parent adoption application. The court must be satisfied not merely that adoption is acceptable, but that adoption is preferable to a parenting order under the Family Law Act 1975 or another legal arrangement that provides security without severing biological ties.
Who Can Apply
The step-parent applicant must be the current spouse or de facto partner of the child's resident parent. Under the Adoption Act 1994:
- The relationship between the resident parent and step-parent must have been stable and continuous for a minimum of three years
- The step-parent must be domiciled or resident in Western Australia
- The step-parent must be at least 18 years old
- All adults in the household must hold a valid Working with Children Check (WWCC)
- The applicant must complete a National Police Clearance and a child protection record check
The resident parent and step-parent apply jointly. The application goes through the Department of Communities and ultimately to the Family Court of Western Australia, which has exclusive jurisdiction over all adoption applications in the state.
The Consent Requirement
Both biological parents must generally provide written consent to the adoption. This is often where step-parent adoption becomes complicated in practice.
Consent must be given in writing and witnessed by an authorized person who confirms the parent understands what they are consenting to. Professional counselling is mandatory before consent is signed. A 28-day revocation period follows, during which the consenting parent can withdraw their consent in writing.
If the other biological parent cannot be located after a diligent search, or is incapable of providing consent, the Family Court can dispense with the requirement under Section 24 of the Act. The court can also dispense with consent if the child has a well-established relationship with the carer and adoption is clearly in the child's best interests.
However, if the other biological parent is alive, known, and capable of consenting but refuses, the path to step-parent adoption becomes significantly more difficult. The court will not grant an adoption order over the objection of a capable biological parent in most circumstances.

What the Family Court Looks For
The Family Court's role is not to process paperwork. A judge must assess whether the adoption order is the "preferable order" compared to alternatives. In practice, this means the court frequently asks: why not a parenting order?
A parenting order under the Family Law Act 1975 can confer day-to-day decision-making authority on a step-parent. It can be structured to provide legal clarity and security without permanently severing the child's relationship with the other biological parent. For older children who have any existing relationship with the other biological parent — or any relationship with grandparents, cousins, or siblings on that side — judges often favor this less permanent option.
The court is more likely to grant a step-parent adoption where:
- The other biological parent has had no involvement in the child's life for a significant period
- The child is young, with no formed attachments to the other biological family
- The absent parent has consistently refused to provide any support or contact
- The adoption would provide legal clarity that a parenting order cannot replicate
- The child themselves, if old enough, expresses a clear preference for the adoption
In 2023-24, only three step-parent adoption orders were granted across the entire state of Western Australia. That figure reflects both the restrictive legal test and the active discouragement built into the process.
The Process Step by Step
If you have assessed the legal landscape and believe step-parent adoption is the right pathway, the process runs as follows:
Step 1 — Attend an information seminar. The Department of Communities requires all adoption applicants, including step-parents, to attend a general information session. These sessions are hosted on Eventbrite and fill quickly.
Step 2 — Education sessions. Two or three mandatory education sessions cover the needs of adopted children and the realities of open adoption under WA law.
Step 3 — Expression of Interest and screening. Within 12 weeks of completing education, you lodge a formal EOI. The Department initiates background checks: WWCC for all household adults, National Police Clearance, child protection record checks, and medical and financial assessments.
Step 4 — Home study. A social worker or psychologist contracted by the Department conducts an intensive assessment through multiple in-home interviews. Their report goes to the Adoption Applications Committee (AAC), which decides on suitability.
Step 5 — Court application. Once the Department gives clearance, the family files an application with the Family Court of Western Australia. The primary forms are Adoption Form 4 (the child adoption application), Adoption Form 1 (the cover sheet), and supporting affidavits. Birth parents must receive formal notice at least 60 days before the application is filed.
Step 6 — The hearing and order. The judge reviews the application, hears evidence, and determines whether the adoption order is preferable. If granted, the Family Court issues a Final Decree of Adoption.
When a Parenting Order Is the Better Option
Western Australian family law practitioners routinely advise step-parents that a parenting order is faster, cheaper, and less disruptive for the child in the majority of situations. A parenting order:
- Does not require the consent of the other biological parent in the same way (it is determined on a best-interests basis)
- Does not sever the child's legal relationship with the other biological family
- Can be varied as circumstances change
- Typically takes months rather than years to finalize
- Does not require attendance at adoption information sessions and education programs
For many families, the goal is simply legal clarity and parental authority — which a parenting order provides. Step-parent adoption is the appropriate mechanism when total legal severance and a permanent transfer of identity is genuinely what the child's welfare requires.

Common Questions
Does the child need to consent? If the child is old enough to understand the implications of adoption, the Family Court will take their views into account. There is no fixed age at which consent is formally required in WA, but the older and more articulate the child, the more weight their views carry.
Can a same-sex couple pursue step-parent adoption? Yes. Same-sex couples are eligible to be assessed for suitability under the Adoption Act 1994 (WA).
How long does it take? The process from first information session to final court order typically takes two to four years, depending on the complexity of the case and how contested the consent element is. This is one reason many families opt for a parenting order if their circumstances allow.
What does it cost? The departmental assessment fee is currently $1,369. Legal and court filing fees vary depending on whether you engage a solicitor and whether the application is contested. Independent legal representation is strongly advisable at the court stage.
