Your spouse or civil partner
Your former spouse or civil partner, if they’ve not remarried or formed another civil partnership
Your children or adopted children
Someone treated as your child by way of marriage – like a step-child
Anyone who was being financially maintained by you (in part or wholly), immediately before your death
Anyone living in your household for the two or more years immediately preceding your death
