How an LLC Files
A foreign LLC that registered in Indiana under an alternate name, because its own name was not available, does not file a certificate for that alternate name. Indiana's law exempts a business other than an individual whose name includes some or all of the true surnames of the people who make it up; Indiana's state FAQ does not address how this applies to an LLC.

If you skip it
A business that trades under an assumed name without filing the certificate the law requires commits a Class B infraction.
Sole proprietors
Indiana requires a sole proprietor whose business name leaves out their surname to register an assumed name. An individual needs a certificate only when the business name leaves out their true surname, and a general partnership only when the name includes none of its partners' surnames. The certificate is filed with the recorder of each county where the business has a place of business or an office.
A sole proprietor registers an assumed name with the county recorder in each county where the business operates.
The filing fee is $25.00. The county recorder charges the $25 fee Indiana law sets for recording a document other than a mortgage. Some counties add a fee by local ordinance.
