Living together
Living together is regarded as a common element in most on-going relationships. It is recognised that, for various reasons, couples may sometimes have to live apart. Provided the separation is temporary and the couple had, at some point since commencement of the relationship lived together, their relationship might still satisfy the requirements of a de facto relationship.
For this reason, the one year relationship criterion does not require the couple to have physically lived together for the entire 12 months, but rather to have been in a de facto relationship for that period.
Partners who are currently not living together may be required to provide additional evidence that they are not living separately and apart on a permanent basis in order to satisfy the requirements of a de facto relationship.
