Where do I file my D/B/A?

The Doing Business As certificate is filed with the Cattaraugus County Clerk's office at 303 Court Street, Little Valley. It costs $25 to file the certificate; $1 for a plain copy and $5 for a certified copy that will be required to open a business checking account. . Check with your bank or credit union to see if they require a plain copy or certified copy. You will need your d/b/a to open a business bank account. The d/b/a protects your business name from being used by anyone else in the County. If you are going to do business in other counties, you do NOT need to register in each county, just in the county the company is based in.
