What does the full faith and credit clause in Article IV require of states?

The full faith and credit clause, found in Article IV of the United States Constitution, requires states to honor the laws, records, and judicial rulings of other states. This means that if one state issues a legal ruling or recognizes a law, other states must respect and uphold that ruling or law as well. This clause helps to facilitate cooperation and consistency among states, ensuring that legal judgments and documents such as marriage licenses, custody determinations, and contracts are valid and enforceable across state lines.

The importance of this clause lies in its role in promoting unity and preventing legal complications that could arise if states refused to recognize each other’s laws and rulings. For example, if a couple is legally married in one state, other states generally have to accept that marriage as valid due to the full faith and credit clause.

The other options do not accurately describe the requirements of the full faith and credit clause. While federal laws may play a role in state recognition to a degree, the clause specifically address the relationships between states rather than federal oversight or uniformity in law.
