This section applies to any notice or other document (including a copy of a document) required or authorised to be given or made by or because of this Act.

The notice or document must be in writing.

The Welsh Ministers may prescribe the form of the notice or document and, unless the regulations provide otherwise, a notice or document not in the prescribed form is of no effect.

A notice or document within subsection (4) is to be treated as signed or executed by each person whose certified electronic signature it has.

If a notice or document in electronic form is authenticated by a person as agent, it is to be regarded for the purposes of any enactment as authenticated by that person under the written authority of that person's principal.

References to an electronic signature and to the certification of such a signature are to be read in accordance with section 7(2) and (3) of the Electronic Communications Act 2000 (c. 7).
