Are dower rights automatically terminated if the spouse who is the dower passes away?

Yes, dower rights are typically automatically terminated upon the death of the spouse who holds those rights. Dower rights are intended to protect the surviving spouse's interest in the deceased spouse's property during their lifetime. Once the spouse passes away, the dower rights no longer apply, as they are linked to the living status of the spouse. However, specific laws can vary by jurisdiction, so it's advisable to consult local laws for precise details.
