An individual who is related to another individual by blood, marriage, de facto union or adoption. For example, an individual's child, grandchild, parent, grandparent, brother or sister is a relation, as is a brother-in-law or sister-in-law, or the child or parent of the individual's spouse. A former spouse and a former de facto spouse are also considered to be relations.

However, an individual's niece, nephew, aunt, uncle or cousin is not considered a relation.
