Advice Column: Stepsibling Inheritance Rights After Parent's Death

A reader submitted a question to Slate's Pay Dirt advice column about their responsibilities toward their stepsister, Brianna, following their stepfather's death in March and their mother's subsequent health decline. The letter describes significant family conflict: Brianna organized a memorial service against the deceased's stated wishes, displayed her own artwork in the program without consulting the letter writer, verbally attacked their mother at the service, and disputed the handling of the father's ashes. The letter writer's mother, now seriously ill with COPD, plans to leave her estate primarily to the letter writer to help support three autistic teenagers. The columnist responds that stepchildren typically have no automatic inheritance rights unless explicitly named in a will, and that life insurance and retirement accounts pass to named beneficiaries outside the will. The columnist recommends consulting an estate attorney given state-specific variations in law.
