Certificate of Sole Proprietor

If you are operating your business as a sole proprietor, under a trade name, or as a general partnership you are required by Maine law to file with the municipal clerk where your business is located (See text of Title 31 M.R.S.A. 1 & 2).

A Certificate of Sole Proprietor is used in trade name protection for a DBA (Doing Business As) within a local community.
