We will pay 7 Days after we transform

(c) Thus, a note payable a certain number of days after the death of the maker, or upon demand after the death of the maker, is a good promissory note, because the event is sure to happened. Carnwright v. Gray, 127 N.Y. 92; Hageman v. Moon, 131 N.Y. 462. See also Shaw v. Camp, 160 Ill. 425: Martin v. Stone, 67 N.H. 367; Price v. Jones, 105 Ind. %44; Bristol v. Warner, 19 Conn. 74. But an instrument payable when, or in so many days after, “A shall become of age,” would not be negotiable, because it is uncertain whether A will live so long.
