"Lex fori" refers to the law of the jurisdiction where a legal case is being heard, while "lex loci" (which can be further specified as "lex loci delicti," "lex loci contractus," etc.) refers to the law of the place where a specific event (like a tort or contract) occurred, or where property is located. "Lex fori" primarily governs procedural matters, while "lex loci" determines the substantive rights and obligations of the parties. *Key Differences:* *Scope:* "Lex fori" focuses on the procedural laws of the court, while "lex loci" focuses on the substantive law governing the underlying legal issue. *Timing:* "Lex fori" applies to the proceedings in the specific court, while "lex loci" applies to the event or issue that is the subject of the case. *Jurisdiction:* "Lex fori" is always the law of the court where the case is heard, regardless of the location of the event or issue. "Lex loci" can be the law of a different jurisdiction if the case involves a dispute arising in a different place. Examples: *Lex fori:* In a contract dispute, the court's procedural rules (like rules of evidence) are determined by the "lex fori" of the jurisdiction where the case is being heard. *Lex loci contractus:* If a contract is signed in England and there's a dispute, the "lex loci contractus" might determine the substantive rights and obligations of the parties, which is the law of England. *Lex loci delicti:* If a tort is committed in France, the "lex loci delicti" (law of the place where the tort was committed) might govern the legal rights and obligations of the parties in a lawsuit.
