Relates to the disqualification of a surviving spouse

This bill changes rules about when a surviving spouse loses inheritance rights. It states that if a marriage is legally declared invalid (annulled) after a spouse dies, the surviving spouse is disqualified from inheriting as if the marriage had never been valid. The key provision retroactively treats the marriage as null from before the death, preventing inheritance even if annulment happens posthumously. This directly affects surviving spouses in estate cases where a marriage is later annulled after the other spouse's death.
