De facto couples, including same-sex couples, who separate on or after 1 March 2009 are entitled to the same legal rights as married couples under the Family Law Act 1975. This legal recognition ensures that both partners in a de facto relationship have access to the same protections and responsibilities as those in a marriage when it comes to separation matters. These rights include property settlements, division of superannuation, parenting arrangements for any children involved, and spousal maintenance if one party requires financial support from the other. This alignment of legal rights reflects the evolving understanding of relationships and aims to treat all couples equally under the law, regardless of marital status.For de facto couples who separated before 1 March 2009, different rules may apply depending on the state or territory in which they lived. In such cases, state laws may govern the division of property and related matters, and outcomes can vary. However, these couples may be able to opt into the federal family law system if they meet certain criteria, allowing them to resolve their matters under the more unified national framework. It is advisable for individuals in these situations to seek legal advice to understand which laws apply and how best to proceed.
