Do promissory notes have to be witnessed and notarized in New Mexico?
No. New Mexico and all other states have adopted the Uniform Commercial Code. Article 3 of the Uniform Commercial Code is captioned "Negotiable Instruments." It governs promissory notes, checks, cashier's checks, and traveler's checks. You may read Section 3-104 of the Uniform Commercial Code at: http://www.law.cornell.edu/ucc/3/article3.htm#s3-104.
