Maintenance work on West Cumbria's only court building is set to overrun after bosses failed to apply for the correct licence for the work in time.
Work began last week at West Cumbria Court House in Workington, including the removal of asbestos from the building following work to upgrade its wifi system.
The Ministry of Justice originally said civil and family cases would move to Carlisle Combined Court until March 12.
A spokesman has now confirmed they will have to remain in Carlisle for a further day "due to a delay in obtaining a work licence".
He confirmed the delay had been in applying for the licence.
Criminal cases, which are held in different court rooms within the building, have moved to Carlisle Magistrates Court until April 18. That date remains unchanged.
