A pilot for a new digital jury system, which has been running in Mayo, has now been extended to Kilkenny, Waterford, and North Tipperary.
The Courts Service says that the new system will provide an easy-to-use, simple online interface.
It will allow people to reply to a jury summons, check the status, and access helpful information.
Anyone who has received a jury summons in these areas can now reply online.
The Courts Service had previously centralised the process of calling people for jury service in Castlebar, Co Mayo.
A four-person team based in a new Jury Summons Unit took on many of the administrative activities involved in calling people to serve on a jury. This work had previously been carried out by staff in local offices in each county.
A review of the move in 2020 found that it had delivered savings of €300,000.
Figures released at the end of last year also showed that the centralised office had issued 420,000 jury summonses over the previous two years.
