the place is very important especially when the party does not indicate “applicable law” or “governing law” in the contract.
Section 13 of Act on the conflict of laws 1938
The question as to what law is applicable to the essential elements or effects of a contract is determined by the intention of the parties thereto. In case where such intention, express or implied, cannot be ascertained, if the parties have the same nationality, the law applicable is the law of common nationality of the parties. If the parties have different nationalities, the law of the place where the contract is made shall govern.
