The Courts Service has said that Cloverhill Courthouse in Dublin will close for essential maintenance at the end of business on 31 July.
It says that the works are expected to continue for around two months.
All District Court cases will move to Courtroom 10 in the Criminal Courts of Justice (CCJ).
The public counter will be closed, and the office will carry out all other business by email (cloverhill@courts.ie) and post as normal.
The Courts Service adds that urgent court business will be dealt with at the Bail Office in the CCJ.
