The law says that siblings are:

  • Brothers and sisters who have at least one parent in common; or
  • People who have lived together and have an ongoing ‘sibling-like’ relationship.

For example, a child or young person might consider someone they lived with in a previous placement to be a sibling, even if they don’t have a parent in common. This definition of ‘sibling’ is important and needs to be considered by everyone who is supporting a child or young person.
