Oklahoma Amended Trade name Report is a form used in the state of Oklahoma to record changes to an existing business entity, such as name, address, or ownership. This form is required when a business entity has undergone changes due to events such as a merger, dissolution, or change of ownership. The Oklahoma Amended Trade name Report must be completed and signed by the business owner, then filed with the Oklahoma Secretary of State's Office. There are two types of Oklahoma Amended Trade name Reports: a standard Amended Trade name Report, and the Short Form Amended Trade name Report. The standard Amended Trade name Report is used for changes that require a more detailed accounting, such as when ownership or name changes have occurred. The Short Form Amended Trade name Report is used when only basic information needs to be updated, such as an address change.
