To the Registrar of Companies (RoC), changing your name is no small matter. As you've already incorporated, you're aware of the rules involved in selecting a name for your company. The same applies for changing your name, too. The procedure is well-defined and to be followed strictly. And just in case you haven't complied with all RoC requirements, you can't go ahead with this until you do. You first need the board to pass a resolution selecting the new name of the company. This new name must also be aligned with the guidelines provided by the RoC.
