The Nevada Certificate of Amendment-Correction To Mark Registration is a document that is filed with the Nevada Secretary of State in order to correct errors or make changes to a trademark or service mark registration in the state. This is generally done when the owner of the mark discovers a mistake in the registration, or wishes to make modifications or alterations to the mark. There are two types of Nevada Certificate of Amendment-Correction To Mark Registration: General Amendment and Amendment to Correct Error. The General Amendment can be used to make any changes to the registration, such as changing the name of the owner, the address, the business name, or the description of the mark. The Amendment to Correct Error is used to correct mistakes on the original registration such as incorrect information or an incorrect filing date. Both types of amendments must be accompanied by a notarized signature from the owner of the mark.
