For security reasons, CDFM certificant name changes cannot be made online. Certificants who have had a legal name change must submit a copy of the original documentation (e.g., marriage license, divorce or name change decree) to certification@asmconline.org or fax to (703) 549-3181 to the attention of the Certification Department. After your name has been updated in your ASMC account, you can order a replacement wall certificate here.
