Even when their own laws diverge, Article IV, Section 1 guarantees that states recognize and honor the state laws and court rulings of other states. For instance, even though a marriage or divorce would not have been permitted under Florida law, if New Jersey residents marry, divorce, or adopt children in New Jersey, Florida must accept these activities as legal.
