I'm my mother's next of kin since my father died, and also her attorney since she lost capacity to deal with her affairs, and executor under her will. When she went into a care home, that was what was noted on her records. I've dealt with her finances, decisions about DNR etc. She died recently, those details would have been passed on by the care home, So who does the Registrar phone about registering the death? My brother, of course.
