De Facto Custody Rights in Victoria: Unmarried Parents and the Family Law Act

Married or Not, the Law Treats Parents Identically

One of the most common anxieties for unmarried parents in Victoria: do I have fewer rights because we never married? The answer is no. Under the Family Law Act 1975, every provision that deals with children — parenting orders, consent orders, parental responsibility, child support — applies identically to married and de facto parents.

The FCFCOA does not ask whether you were married. It does not treat married parents' claims to parenting time more favourably. The six best interests factors under Section 60CC apply to every child, regardless of their parents' relationship status.

Both parents ordinarily have parental responsibility from birth, and separation does not change it by itself. If an unmarried father's legal parentage is not established, that parentage may need to be established; once it is, the parenting framework applies in the same way regardless of whether the parents married.

What Is Different: Separation Dates and Property

The parenting process is the same, but the separation process has one key difference that trips people up. Married couples must wait 12 months and one day after separation to file for divorce. De facto couples do not file for divorce at all — there is no legal marriage to dissolve.

This means de facto parents often resolve parenting arrangements faster because they are not waiting on a divorce timeline. But there is a corresponding time pressure on property: de facto couples must apply for property and financial orders within two years of their final separation, or seek leave of the court to file outside that window. Married couples generally have 12 months from the date their divorce order becomes final to apply for property or maintenance orders.

The other practical difference is proving when the separation actually occurred. Married couples can point to a formal date of separation. De facto couples — especially those who were never on a joint lease, never had joint bank accounts, or who continue living in the same house after the relationship ends — may need to establish their separation date through documentary evidence.

Separating Under One Roof

Australian law recognises that many parents continue living in the same house after separating, especially when children are involved and neither parent can immediately afford to move out. This applies to both married and de facto couples.

To establish that you are separated under one roof, you generally need to show that the relationship has ended in substance: separate sleeping arrangements, separate finances where possible, separate social lives, and clear communication (ideally in writing) that the relationship is over. Diary entries, text messages to family members, and changes to domestic routines all serve as evidence.

For de facto couples, this documentation is particularly important because there is no marriage certificate establishing when the relationship began or ended. If you later disagree about the separation date — which affects the two-year property limitation period — your records will matter.

The Parenting Process Step by Step

The process for de facto parents in Victoria follows the same sequence as for married parents:

Family Dispute Resolution first. For a contested parenting application, the parties must make a genuine effort through FDR with an accredited practitioner and obtain a Section 60I certificate before filing, unless an exemption applies (including family violence, child abuse, or urgency). Consent applications and responses are exempt from filing a certificate.

Negotiate a parenting plan or consent orders. If mediation produces an agreement, you can document it as a parenting plan (flexible, not court-enforceable) or submit it as consent orders through the Commonwealth Courts Portal (legally binding, court-enforceable). The consent order application requires the same forms regardless of whether you were married: the Application for Consent Orders, Proposed Orders Template, and the Notice of Child Abuse, Family Violence or Risk (Form 4).

File for parenting orders if negotiation fails. If you cannot reach agreement, you file an Initiating Application for parenting orders in the FCFCOA. The court then applies the standard process: Lighthouse Project risk screening, case management, and ultimately a hearing or trial.

Child Support Applies the Same Way

Services Australia administers child support for all parents, married and de facto, using the same formula. The eight-step calculation based on combined income, self-support amounts, and care percentages (measured in overnight stays per year) does not vary based on relationship status.

The Victoria Child Custody & Parenting Plan Guide covers the full parenting process for both married and de facto parents — including a separation documentation checklist, schedule templates, and a step-by-step consent order filing guide.
