Comity

In law, comity specifically refers to legal reciprocity &mdash; the principle that one jurisdiction will extend certain courtesies to other nations (or other jurisdictions within the same nation), particularly by recognizing the validity and effect of their executive, legislative, and judicial acts. The term refers to the idea that courts should not act in a way that demeans the jurisdiction, laws, or judicial decisions of another jurisdiction.

Part of the presumption of comity is that other jurisdictions will reciprocate the courtesy shown to them. Many statutes relating to the enforcement of foreign judgments require that the judgments of a particular jurisdiction will be recognized and enforced by a forum only to the extent that the other jurisdiction would recognize and enforce the judgments rendered by that forum.
