The District of Columbia General Forms (Will)-Notice of Registration is a document used to register a business name in the District of Columbia. It is a form issued by the Office of the Chief Financial Officer (CFO) of the District of Columbia which serves to inform the public that a business is operating in the district. It is a legal requirement for all businesses operating in the District of Columbia to obtain a Notice of Registration from the CFO. There are two types of District of Columbia General Forms (Will)-Notice of Registration: the Wil-4 and the Wil-5. The Wil-4 is used to register a business name for a limited liability company (LLC) or a corporation, while the Wil-5 is used to register a business name for a sole proprietorship. Both forms include information such as the name of the business, address, owner name, contact information, and type of business.
