A business or partnership must file a business certificate in all counties in which it conducts or transacts business, not just in the county where its offices are located. Such filing generally initiates in the county where the business address is located.
There are certain statutory restrictions regarding what you may use as a business name; not all submitted names or titles are permissible. See General Business Law #130 (GBS) for additional information.
An attorney-in-fact or agent may not sign on behalf of an individual or partner filing a business.
