AND ANOTHER TEXT I FOUND USEFUL. IN RED UNDERLINED THAT BIT.
Registration or Registering of a Trade / Trade Business Name.
In general, you are required by law to notarize (some states) Apply, Register & Get (Apply, Register & Get ) and publish (in some states) a Trade business name statement, (otherwise called a Assumed Business Name Certificate, DBA Doing Business As Statement, a Trade Business Name Certificate, or a Trade Assumed Business Name ) if the business name is a name that is different from the name of the proprietor, partnership or corporation doing business with that name.
Example, you are Al Pacone doing business as "Business Consulting Services" - you need to Apply, Register & Get the name "Business Consulting Services". Example: you are Hulliburton Corp, doing business as Robem & Cheetem - you need to Apply, Register & Get "Robem & Cheetem" under the corporation. In addition, if the business name includes the name of the owner and implies additional owners (for example: Al Pacone & Associates,) you are required to Apply, Register & Get a Trade business name as "Al Pacone & Associates".
