Calhoun/Johnson Company d/b/a Williams Lumber Company (Williams) sold building materials to Donald Miller d/b/a Millercraft Construction Company (Millercraft) on credit. Miller had signed a personal guaranty for the materials. Miller requested lien waivers from Williams for four of his projects and asked for them from Fabian Boudreau, Williams’s credit manager. Fabian refused to grant the waivers because Miller was $28,000 delinquent on his account. Miller agreed to bring his account current with the exception of $11,000 for which he signed a no-interest promissory note. Miller obtained the lien waivers and then defaulted on the note. Williams brought suit for payment, and Williams said there was lack of consideration and that the note was not valid. He said he must give value to be able to recover on the note. Was he correct?
