Then

In the grammatical sense is an adverb of time. In such case the context should plainly show that it was so used before effect is thus given to it. 233 Pa. St. 35; Ann. Cas. 1913B 321; 2 Atk. 308; 19 N. Mex. 477. It is often used for the purpose of denoting an event or contingency, and is equivalent to the words "in that event" or "in that case." Frequently used in legal instruments to designate limitations of estates, or future contingencies on which they are made to depend. When thus used it becomes a word of reference, and does not indicate any particular point of time. 6 Gray (Mass.) 24; 16 Ga. 557; Ann. Cas. 1913B 321. See "Then and There."

As an adverb, means "at that time," referring to a time specified, either past or future. Mangum v. Piester, 16 S. C. 329. See Dove v. Torr, 128 Mass. 40. It may also denote a contingency and be equivalent to "in that event"; Merritt v. Portchester, 8 Hun (N. Y.) 40; or "further." 2 Jarm. 595. In a will it has been held to import the time at which the class described is to be ascertained; 3 Ves. 486; but see 17 Beav. 417.
