A treaty is said to be what when those who have drafted it agree that it is in final form?

The term that describes a treaty as being in final form once it has been drafted and agreed upon by those involved is "adopted." In the context of international law, adopting a treaty means that the negotiating parties have agreed on its content and that it is now ready to be finalized and implemented through a formal ratification process. Adoption signifies that the text of the treaty is settled and that the parties acknowledge the agreed terms, although it does not yet have binding legal effect on the parties until ratification occurs.

Ratification, on the other hand, refers to the formal approval process that follows adoption, typically involving each country’s legislative or governing body. Executed is often used in a different context, indicating that a contract or agreement has been signed and put into effect. Enacted usually pertains to legislation that has been passed by a legislative body and made into law, rather than relating to the international treaty process. Thus, "adopted" is the correct term to use in this situation.
