Executory 一词常用于法律语境中，表示(of a law, agreement, etc) coming into operation at a future date; not yet effective (法律、协议等)将来生效的。

l Executory judgement待执行判决

l Executory consideration 待履行的对价

对价可分为待履行的对价（executory consideration ）、已履行的对价（ executed consideration）。

l Executory contract 待履行合同

是指合同各方尚未履行任何合同义务，或部分履行了同等义务的合同。企业于其他企业签订的尚未履行任何合同义务或部分履行了同等义务的商品买卖合同、劳务合同、租赁合同等，均属于待执行合同。

Executory contract：An executory contract is a contract which has not yet been fully performed, that is to say, fully executed. To put it another way, it's a contract under which both sides still have important performance remaining.

l Executory devise 将来生效的财产遗赠

指不动产遗赠的生效取决于将来某一事件的发生。因此，该事件的发生与否决定着该项不动产的将来归属，且在此之前，任何人都无权转让该项不动产。如果受遗赠人在该事件发生前死亡，则该项不动产由在该事件发生时该受遗赠人的继承人继承，而不是由该受遗赠人死亡时的继承人继承。
