Lex Fori
Literal meaning: “The law of the forum; the law of the court”
What does the Latin term "Lex Fori" mean in law?
Lex fori refers to the law of the jurisdiction in which the court hearing the case is situated. In conflict of laws analysis, the lex fori is the default body of law that the court applies to procedural matters, even when the substantive rights of the parties are governed by the law of another jurisdiction. The distinction between substance and procedure is therefore critical in choice of law analysis because procedural questions are almost always resolved under the lex fori. The doctrine is one of several choice of law principles, alongside lex loci delicti (law of the place of the wrong) and lex loci contractus (law of the place of contracting). Determining whether an issue is substantive or procedural under the lex fori can be outcome-determinative.

How It's Used
Courts apply lex fori to resolve procedural questions such as statutes of limitations (in some jurisdictions), evidence rules, and pleading requirements. Choice of law disputes often center on whether a particular issue is substantive or procedural, since the classification determines whether the lex fori or a foreign law applies.
