Coming Into Force

  • Treaties do not automatically come into force when signed.
  • Most have a clause specifying the requirements of the treaty entering into force.
  • A treaty usually only binds parties to the agreement. 
  • Bilateral treaties usually enter into force when both parties agree to be bound as of a certain date.
