The passing of marriage equality legislation in Australia in December 2017 marked a historic moment for equality and recognition. For the first time, same-sex couples were granted the same rights to marry as heterosexual couples under Australian law. But beyond the right to marry, this reform also brought significant changes in how family law applies to same-sex couples, particularly in areas like divorce, parenting, and property settlements.
In this article, we explore how family law has evolved for same-sex couples since marriage equality, what rights and protections now exist, and where challenges remain.
Marriage Equality in Australia – A Defining Moment
On 9 December 2017, the Marriage Act 1961 was amended to redefine marriage as “the union of 2 people to the exclusion of all others, voluntarily entered into for life.” This change removed gendered language and ensured that same-sex marriages performed both in Australia and overseas would be legally recognised.
This was more than symbolic as it gave same-sex couples equal access to the legal framework of marriage, including rights and obligations in relation to property, inheritance, taxation, superannuation, and family law disputes.
Family Law Changes for Same-Sex Couples
1. Marriage and Divorce
Same-sex couples now have the same rights to marry as any other couple. Likewise, they also have the same obligations when a marriage breaks down. Divorce proceedings for same-sex couples are governed by the Family Law Act 1975 (Cth) and follow the same process as opposite-sex couples, including demonstrating that the marriage has irretrievably broken down after 12 months of separation.
2. Parenting and Children
Parenting arrangements for same-sex couples are determined under the same “best interests of the child” principle that applies to all families. Importantly, reforms to family law mean that both partners in a same-sex relationship may be legally recognised as parents in circumstances such as:
- Children born through assisted reproductive technology (ART), where both partners consented to the procedure.
- Adoption, where same-sex couples now have the same rights to adopt as heterosexual couples.
Despite these advancements, some complexities can still arise in areas like surrogacy, which remains subject to strict state-based laws.
3. Property Settlements
Same-sex couples are entitled to the same property settlement process under the Family Law Act as heterosexual couples, whether they are married or in a de facto relationship. The courts consider contributions (financial and non-financial), future needs, and fairness when dividing property.
For de facto same-sex couples, the recognition of rights predates marriage equality. Since 2009, the Family Court has had jurisdiction to deal with de facto property disputes, giving same-sex de facto couples the same entitlements as opposite-sex de facto couples.
4. Superannuation and Financial Entitlements
With marriage equality, superannuation, tax, and social security entitlements have been brought into line for same-sex couples. Superannuation death benefits can now be paid to a same-sex spouse, and tax concessions for married couples apply equally.
What Hasn’t Changed?
While marriage equality brought sweeping reforms, challenges remain:
- International Recognition – Not all countries recognise same-sex marriages. This can create complications for couples who marry overseas or who move internationally.
- Surrogacy Laws – Surrogacy arrangements remain inconsistent across Australian states, with some jurisdictions banning commercial surrogacy. Same-sex couples often face added hurdles in navigating these laws.
- Social and Cultural Barriers – Despite legal equality, many same-sex couples still report challenges in accessing services or face stigma in legal processes.
Why Legal Advice Matters for Same-Sex Couples
While the law now provides a framework of equality, the reality is that family law disputes, whether relating to divorce, parenting, or property, can still be complex. For same-sex couples, issues such as parentage in non-traditional family structures, recognition of overseas marriages, or navigating surrogacy laws make legal advice essential.
