11.—(1) A party may be represented in any proceedings by a legal representative or lay representative whose details must be communicated to the First-tier Tribunal prior to any hearing.
(2) A party may show any document or communicate any information about the proceedings to that party’s lay representative or legal representative without contravening any prohibition or restriction on disclosure of the document or information.
(3) Where a document or information is disclosed under paragraph (2), the lay representative or legal representative is subject to any prohibition or restriction on disclosure in the same way that the party is.
(4) Anything permitted or required to be done by a party under these Rules, a practice direction or an order may be done by a lay representative, except signing of a witness statement.
(5) The First-tier Tribunal may order that a lay representative is not to represent a party if—
(a)it is of the opinion that the lay representative is an unsuitable person to act as a lay representative (whether generally or in the proceedings concerned); or
(b)it is satisfied that to do so would be in the interests of the efficient administration of justice.
