Illinois Declination of Office is the process of officially declining to serve in a public office or an appointed position in the state of Illinois. It is also known as the Illinois Resignation of Office. Illinois Declination of Office can be done in two ways: by filing a written statement with the Secretary of State or by written notification to the appointing authority. The first type of Illinois Declination of Office is a written statement filed with the Secretary of State's office. This statement must include the name and address of the person declining the office, the name of the office being declined, and a statement that the declination is irrevocable. The Secretary of State's office will then publish the statement in the Illinois Register. The second type of Illinois Declination of Office is a written notification sent to the appointing authority. This notification must include the name and address of the person declining the office, the name of the office being declined, and a statement that the declination is irrevocable. The appointing authority will then update their records to reflect the declination. Both types of Illinois Declination of Office must be done in a timely manner and in accordance with the applicable laws of the state of Illinois.
