When you find that someone else in your area or industry is using a confusingly similar name, you should select another to avoid being sued. If you are looking for a very simple name that describes the business, like "Flash Messenger Service," you may have to try several times to find a name that no one else is using.
If the business is being operated as a sole proprietorship, with only one owner, or as a partnership, the company name must be recorded with the Recorder of Deeds in the county where the business is located. This will cost about $100. If the business is a corporation or LLC, the papers on file with the Secretary of State take the place of recording the name.
