They will be forwarded to the appropriate Section and will be acknowledged as soon as possible. Proceedings may also be served by post, in accordance with Order 121 of the Rules of the Superior Courts.


When corresponding with the CSSO at this time we encourage you to do so by email unless it is strictly necessary to do so by post, in which case you should notify the relevant person or Section by email that you have forwarded documents by post.
