1. How are interlocutory applications made?

Interlocutory applications are usually made by a summons, supported by affidavits or affirmations, which have to be filed with the court and served on the other party. You can find examples of the forms used to apply for a "summons (to extend time to file & serve defence)" and a "summons (for directions)" for High Court cases on the Judiciary website at http://www.judiciary.gov.hk/en/crt_services/forms/hc_cfi.htm .

The other party may then file affidavits or affirmations with the court to oppose the application. A copy of such opposing affidavits or affirmations must also be served on (delivered to) the party making the original application for interlocutory proceedings.

The applying party may, upon receiving the affidavits or affirmations in opposition, file and serve affidavits or affirmations in reply.

There should be no further affidavit or affirmation from either party unless there is a court order granting permission for any party to do so.
