What is a De Facto Relationship in Australian Family Law?

A de facto relationship in Australia refers to two people living together as a couple without being legally married. Despite not being married, de facto couples have similar legal rights and responsibilities as married couples, particularly in property settlements, child custody, and spousal maintenance. Understanding the legal definition and rights of de facto relationships is vital when navigating separation and family law matters.

What Defines a De Facto Relationship?

Under the Family Law Act 1975, a de facto relationship is recognised if two people live together on a genuine domestic basis. Key features include:

  • Cohabitation: Partners typically live together, but short periods apart due to work or family obligations may not invalidate the relationship.
  • Duration: The relationship must generally last at least two years unless there are children or substantial financial contributions.
  • Financial Interdependence: Joint financial responsibilities, shared expenses, or co-owned property can indicate a de facto relationship.
  • Commitment: Evidence of shared domestic duties, mutual support, and emotional commitment is important.
  • Public Recognition: The relationship should be recognised by family, friends, and the community as genuine.


Some states, like New South Wales, allow couples to register their de facto relationship, although registration is not mandatory for recognition.

Legal Rights of De Facto Couples

Once a de facto relationship is recognised, both parties have similar rights to married couples, including:

  • Property Settlement: Assets and debts are divided fairly, considering contributions (financial and non-financial), the relationship’s length, and future needs. Superannuation splitting is also available.
  • Spousal Maintenance: A de facto partner may claim maintenance if unable to support themselves post-separation.
  • Parenting and Custody: De facto parents have equal rights and obligations regarding child custody and care arrangements.


De Facto Property Settlements

Property and financial settlements for de facto couples follow similar principles to those for married couples. The division considers:

  • Contributions: Financial (e.g., income, savings) and non-financial (e.g., homemaking, child care) contributions.
  • Future Needs: Factors like age, health, earning capacity, and child custody responsibilities.
  • Relationship Length: Longer relationships often result in more equal divisions.


De facto couples must apply for property settlements within two years of separation. Missing this deadline may require court approval to proceed.
