My brother-in-law has passed away as a result of a fatal car accident. The court ruled that next of kin is the mother to his children (both under 18). She is considered a domestic partner. Previously, they had been in a 7-year relationship but never married. Leading to his death, they had been separated and not living together for two years due to her cheating on him for a few months. Can this be considered adultery in the eyes of the family court as they described their previous relationship as though they were married. Can this change the decision of her being next of kin?
