A representative, appointed and qualified as provided in
Secs. 725.362 and 725.363, may make or give on behalf of the party he
or she represents, any request or notice relative to any proceeding
before an adjudication officer, including formal hearing and review,
except that such representative may not execute a claim for benefits,
unless he or she is a person designated in Sec. 725.301 as authorized
to execute a claim. A representative shall be entitled to present or
elicit evidence and make allegations as to facts and law in any
proceeding affecting the party represented and to obtain information
with respect to the claim of such party to the same extent as such
party. Notice given to any party of any administrative action,
determination, or decision, or request to any party for the production
of evidence shall be sent to the representative of such party and such
notice or request shall have the same force and effect as if it had
been sent to the party represented.
