Can a Long Term De-facto Be Determined if You Don’t Live Together De Facto Relationships

A de facto relationship has been explained in a previous article. We explore a case where the Full Court of the Family Court of Australia found that a de facto relationship existed for 18 months between a married man and a former sex worker.


  • The parties met at a massage parlour where Ms Sha worked in late 2011.
  • In February/March 2012, the parties began a sexual relationship
  • In mid-March 2012, the parties discussed having a baby together and Ms Cham stopped working at the massage parlour.
  • The parties began to see each other at Ms Cham’s home where Mr Cha occasionally stayed overnight.
  • Mr Cham provided financial support to Ms Sha through monthly and lump-sum payments. The payments were applied towards Ms Sha’s rental accommodation and general living expenses as she no longer worked at the massage parlour.
  • The parties entered into a Financial Agreement in August 2012.
  • Ms Sha fell pregnant in September 2012 and the parties had a child together in mid-2013.
  • Mr Cham and his former wife, separated in October 2012.
  • In November 2013, Ms Sha signed the separation declaration required under the Financial Agreement.
  • Ms Sha filed proceedings in the Federal Circuit Court to enforce the Financial Agreement.

Mr Cham argued that he and Ms Sha were not in a de facto relationship at the time of entering into the Financial Agreement. The Court deemed a de facto relationship to be in existence at the time of entering the Financial Agreement.


  • A de facto relationship can exist even though one of the spouses remains legally married.
  • To determine whether a de facto relationship exists, the circumstances of the relationship need to be assessed and given weight as the Court deems appropriate.
  • Mr Cham assured Ms Sha that he would support her and their future child which was evidenced by entering into the Financial Agreement.
  • Each factor under Section 4AA of the Family Law Act should not be looked at standing alone, but as to the context of the relationship as a whole.

This case highlights the importance of seeking legal advice regarding your specific matter, especially if you are considering entering into a de facto prenuptial agreement Australia or a Financial Agreement during your relationship, pre-marriage, or post-separation.
