1.1.C.40 Cohabitation, living together (FTB)


For the purposes of FTB, these terms are used only in relation to presumption of parentage (1.1.P.110) for child support (1.1.C.20).

Definition: cohabitation

The term 'cohabitation' refers to living together in a de facto relationship rather than just sharing accommodation.

When a separated couple recommence living together, they are considered to be 'cohabiting' in situations where the couple intended to resume their relationship, even if this intention only lasted a brief time.

Definition: living together

The term 'living together' rather than 'cohabitation' is used in the application for a child support assessment, as this is a more commonly used expression.

Decision about living together

For the purposes of establishing presumption of parentage, it is the responsibility of the individual (1.1.I.90), not Centrelink staff, to decide if they and the named parent of the child were living together. Centrelink staff do not need to:

  • apply the FAAct criteria for de facto relationships, or
  • make a decision about whether a person was in a de facto relationship.
