Can a Commissioner of Oaths witness my signature or certify my document for use overseas?
No. South African public, company/commercial or educational documents can only be signed before a notary public. Please note that multiple page documents must be signed or sealed by the Notary Public at the bottom of each page of the notarised document required to be legalised, or apostilled. see the accession notice and more specifically article.
