PERSONS LIABLE:
1. Any person who uses any name different from the one w/ w/c he was registered at birth in
    the office of the local civil registry, or w/ w/c he was registered in the bureau of immigration
    upon entry, or such substitute name as may have been authorized by a competent court.
    Exempted from criminal liability are persons who use another name as a pseudonym solely
    for literary, cinema, television, radio, or other entertainment purposes and in athletic
    events; and
2. Any person who having been baptized with a name different from what was registered, or
    who had obtained judicial authority for use of an alias, or who uses a pseudonym, represents
    himself in any public or private document w/o stating or affixing his real or original name
    or aliases or pseudonym he is authorized to use.

NOTES:

A judicial authority must be first secured by a person who desires to use an alias.

However, a common-law wife does not incur criminal liability under the Anti-Alias Law if she
uses the surname of the man she has been living w/ for the past 20 years and has been introducing
herself to the public as his wife.
