As from next month 10 temporary courts are being set up to help clear a backlog of hearings caused by the coronavirus pandemic.
From next week, they will hear civil, family and tribunals work as well as non-custodial crime cases.
Justice Secretary Robert Buckland said the new "Nightingale Courts" would help with "reducing delays and delivering speedier justice for victims".
The introduction of the new courts means there will be more room in current courts for hearings where cells and secure dock facilities are needed, including jury trials where the defendant is in custody.
Mr Buckland, also the Lord Chancellor, said: "They will help boost capacity across our courts and tribunals - reducing delays and delivering speedier justice for victims. "But we won't stop there. Together with the judiciary, courts staff and legal sector, I am determined that we must pursue every available option to ensure our courts recover as quickly as possible."
