RHYL County Court is set to be the last building to shut as part of a closure programme by the Ministry of Justice.
The court is set to shut in April with plans for a extension to facilities at Prestatyn magistrates court set to replace the functions of the Rhyl site.
More than 138 other buildings have closed under the cost saving measure and of the remaining sites Rhyl's closure is scheduled to be the last.
Chris Ruane, Vale of Clwyd MP, said: “The decision to close Rhyl Court was a blow not just for the town but for justice as a whole.
“The government completely ignored the arguments against closure in a quest to pursue its relentless attack against the public sector and public sector workers.
“The consultation carried out into the closure of Rhyl Court was completely flawed and ignored evidence against the closures and it amounts to the removal of justice.”
The court deals with civil matters ,district registry, divorce and bankruptcy cases.
The closure of the Rhyl court is understood to be dependent on an extension on to Prestatyn magistrates’ court but since 2010 North Wales Police have vacated the offices adjoining the courthouse.
A spokesman for the Ministry of Justice confirmed the intention was still to move to Prestatyn.
