I have a company and it would be useful in my situation to have a few different trading names for the single company. Im wondering is it ok to have 4 very different trading names for that 1 company?
you can register as many traidng names as you want but registering trading names may not give you the protection you may think you have, unless you actually use the name, or show that you have had plans to do so.
You need to study the law on this (and copyright) -there are many cases where someone registers loads of names and wrongly believes that nobody else can use them.
