“The lex loci contractus controls the nature, construction, and validity of the contract; and on this broad foundation the law of contracts, founded on necessity and commercial convenience, is said to have been originally established. If the rule were otherwise, the citizens of one country could not safely contract, or carry on commerce, in the territories of another.” 2 James Kent, Commentaries on American Law *454 (George Comstock ed., 11th ed. 1866).
