Lloyd and Mario Spaulding entered into a contract to purchase property from Richard and Robert Krajcir. The two Spaulding brothers signed a promissory note to the Krajcir brothers with the following language: “The amount of $10,000 [is] to be paid sellers at the time of the initial closing [delivery of the deed]; plus, the principal amount payable to sellers at the time of the final indorsement of the subject H.U.D. loan.” In litigation over the note, the Spauldings said it was not a negotiable instrument. The lower court found it to be a negotiable promissory note and the Spaulding partners appealed. Is the note negotiable? [Krajcir v Egid, 712 NE2d 917 (Ill App)]
