Full faith and credit
Full faith and credit: Two different ideas. Under Article IV, Section 1 of the Constitution, each state must give "Full Faith and Credit" to the public acts, records and judicial proceedings of every other state. In public finance, "full faith and credit" describes the government's pledge to repay its debt; for example, 31 U.S.C. § 3123 pledges the faith of the United States to pay Treasury obligations issued under that chapter.

What full faith and credit means
In short, full faith and credit is a term you will meet in court papers, rules and legal research. The definition above gives its usual meaning in American civil practice. However, the exact meaning can depend on the rule, statute or court decision that uses it. So it helps to read the term in context.

Next, check whether your court has a local rule that uses full faith and credit in a special way. Then look at recent decisions from courts in your jurisdiction. They show how judges apply the term today. Also, remember that state law can differ from federal law. For that reason, use our state procedures guide to find your state’s rules.
