Who is next of kin when there are 3 children?

When there are three children, all of them are typically considered next of kin. In legal terms, next of kin usually refers to the closest living relatives, which can include parents, siblings, and children. If a parent has passed away, the children would collectively hold the status of next of kin. The specifics can vary based on jurisdiction and the context in which "next of kin" is being considered, such as inheritance or medical decisions.
