Appears to be non-existent in Maine from In re Reben, 342 A. 2d 688 - Me: Supreme Judicial Court 1975 and The Right to Control One’s Name, Kushner UCLA law review:
[T]he Maine Supreme Court noted the freedom to use additional names informally in an opinion in which it also declared the common law right “superseded.”68 The court stated:
We recognize that a person may informally adopt a stage name, a nom de plume, or a business name or one for social purposes which is not his true name and, while using such a name, may obligate himself legally and, under certain conditions, enter into agreements which are binding upon other parties. On the other hand, there are situations in which the public interest entitles the State to demand that a person identify himself by his true, legal name in connection with his performance of certain activities
The nonjudicial name change permitted by the common law was always subject to a possible judicial determination that the attempted nonjudicial change had failed because it was motivated by fraud, that is, by a purpose to deceive. We are convinced that our own original statute was intended to bring the ancient principles 695*695 into consonance with modern needs by permitting the individual the same right but with a record, a definite date of change, and a determination in advance as to presence or absence of purpose to deceive. The common law method which would serve no further purpose was superseded.
