Bouvier’s Law Dictionary, 1856
COMITY. Courtesy; a disposition to accommodate. 2. Courts of justice in one state will, out of comity, enforce the laws of another state, when by such enforcement they will not violate their laws or inflict. an injury on some one of their own citizens; as, for example, the discharge of a debtor under the insolvent laws of one state, will be respected in another state, where there is a reciprocity in this respect. 3. It is a general rule that the municipal laws of a country do not extend beyond its limits, and cannot be enforced in another, except on the principle of comity. But when those laws clash and interfere with the rights of citizens, or the laws of the countries where the parties to the contract seek to enforce it, as one or the other must give way, those prevailing where the relief is sought must have the preference. 2 Mart.Lo.Rep.N.S. 93; S.C. 2 Harr.Cond.Lo. Rep. 606, 609; 2 B. & C. 448, 471; 6 Binn. 353; 5 Cranch, 299; 2 Mass. 84; 6 Mass. 358; 7 Mart.Lo.R. 318. See Conflict of Laws; Lex loci contractus.
