Meaning of de facto relationship
(1) A person is in a de facto relationship with another person if:
(a) the persons are not legally married to each other; and
(b) the persons are not related by family (see subsection (6)); and
(c) having regard to all the circumstances of their relationship, they have a relationship as a couple living together on a genuine domestic basis.

(5) For the purposes of this Act:
(a) a de facto relationship can exist between 2 persons of different sexes and between 2 persons of the same sex; and

When 2 persons are related by family
(6) For the purposes of subsection (1), 2 persons are related by family if:

(b) one is another descendant of the other (even if the relationship between them is traced through an adoptive parent); or
(c) they have a parent in common (who may be an adoptive parent of either or both of them).
For this purpose, disregard whether an adoption is declared void or has ceased to have effect.
