Old law
Old law marks a naturalization paper made before September 27, 1906, under the rules in force before the Basic Naturalization Act took effect.
Federal clerks used the phrase to set older papers apart from those on the new standard forms. An immigrant who filed an old law declaration could later petition under the new law, so the declaration sits only in the original court while the petition is also copied in the C-File.
Old law certificates often lack birth dates and arrival details. If someone later asked for a replacement, the request went into a C-File, which may add facts the original papers never held.
