The Maine Secretary of State requires all businesses to conduct a Maine Business Name Search before registering to start operations. You should follow the business naming guidelines laid down by the SOS. If you want to run a Sole Proprietorship, you are allowed to either use your own given name or an assumed name. You are free to start the business without filing any legal papers with the SOS if you choose to use your own given name.

If you choose to use an assumed or trade name, you are required to make sure it is distinguishable from any other name registered in the Maine SOS database. Furthermore, you are required to make sure the name is filed in the Maine SOS business records. The filing fee is $10, although it may be different in some cities.

The fee for name reservation for registration at a later date is $20. The Maine SOS allows the reservation of names for up to 120 days. After the time lapses, someone else can be allowed to register or reserve the name unless you request an extension before the 120 days lapses. Be certain that the name is not taken by conducting a name search at the Maine site. To conduct an LLC or Corporation search in Maine, visit the Maine Secretary of State Website.
