New Hampshire Form TN-9 Trade Name Discontinuance is a document filed with the New Hampshire Secretary of State's Office when a business wants to discontinue use of its trade name. It notifies the public that the business is no longer using the trade name and provides important legal protection for the owners of the trade name. There are two types of New Hampshire Form TN-9 Trade Name Discontinuance: Voluntary Trade Name Discontinuance and Mandatory Trade Name Discontinuance. Voluntary Trade Name Discontinuance is when the business chooses to discontinue use of its trade name and Mandatory Trade Name Discontinuance is when the New Hampshire Secretary of State's Office revokes the business's trade name due to certain violations or circumstances.
