The Illinois Notice of Change of Address & Name is a form that must be submitted to the Illinois Secretary of State if a person changes their address or name. The form is used to update the personal information on file with the Secretary of State, including the name and address of the person in question. There are two types of Illinois Notice of Change of Address & Name: one for individuals, and one for business entities. For individuals, the form requires the name, date of birth, old address, and new address of the person in question. The form must be signed by the individual in question and notarized by a notary public. For business entities, the form requires the name of the business, the name of the registered agent, the address of the registered office, and the address of the new registered office. The form must be signed by a corporate officer and notarized by a notary public. The completed form must be submitted to the Illinois Secretary of State along with the appropriate filing fee. Once the form is received and processed, the Secretary of State will update the person's or business entity's address and name on file.
