Documents relating to a Welsh company may be drawn up and delivered to the registrar in Welsh.
On delivery to the registrar any such document must be accompanied by a certified translation into English, unless it is—
of a description excepted from that requirement by regulations made by the Secretary of State, or
in a form prescribed in Welsh (or partly in Welsh and partly in English) by virtue of section 26 of the Welsh Language Act 1993 (c. 38).
A Welsh company may deliver to the registrar a certified translation into Welsh of any document in English that relates to the company and is or has been delivered to the registrar.
Section 1105 (which requires certified translations into English of documents delivered to the registrar in another language) does not apply to a document relating to a Welsh company that is drawn up and delivered in Welsh.
