The district director is empowered to resolve disputes with respect
to claims in a manner designed to protect the rights of the parties and
also to resolve such disputes at the earliest practicable date. This
will generally be accomplished by informal discussions by telephone or
by conferences at the district director's office. Some cases will be
handled by written correspondence. The regulations governing informal
conferences at the district director's office with all parties present
are set forth below. When handling claims by telephone, or at the office
with only one of the parties, the district director and his staff shall
make certain that a full written record be made of the matters discussed
and that such record be placed in the administrative file. When claims
are handled by correspondence, copies of all communications shall
constitute the administrative file.
