I think it was somebody here who introduced me to this new term?

Locus Celebrationis.

Locus Celebrationis


The locus celebrationis of a contract is the place where the contract is entered into. If the contract is entered into as the result of a series of acts or negotiations, leading thereto, some of which took place in one state, and others in another, the situs of the contract will be the place where the act took place which rendered the contract binding.



The law of the locus celebrationis determines the formal validity of the contract and the capacity of the parties.
